Drug Class:
Highlights of Prescribing Information
NGENLA (somatrogon-ghla) injection, for subcutaneous use
Initial U.S. Approval: 2023
Indications and Usage for Ngenla
NGENLA is a human growth hormone analog indicated for treatment of pediatric patients aged 3 years and older who have growth failure due to inadequate secretion of endogenous growth hormone (1).
Ngenla Dosage and Administration
- •
- NGENLA treatment should be supervised by a healthcare provider who is experienced in the diagnosis and management of pediatric patients with growth hormone deficiency (2.1).
- •
- Administer NGENLA by subcutaneous injection once weekly, on the same day each week, at any time of the day in the abdomen, thighs, buttocks, or upper arms with weekly rotation of injection site (2.1).
- •
- The recommended dosage is 0.66 mg/kg based on actual body weight administered once weekly (2.3).
- •
- Individualize dosage for each patient based on the growth response (2.3).
- •
- Patients switching from daily growth hormone may initiate treatment with once-weekly NGENLA on the day following their last daily injection (2.3).
- •
- If more than one injection is required to deliver a complete dose, each injection should be administered at a different injection site (2.3).
Dosage Forms and Strengths
Injection:
- •
- 24 mg/1.2 mL (20 mg/mL) single-patient-use prefilled pen that delivers a dose in 0.2 mg increments (3).
- •
- 60 mg/1.2 mL (50 mg/mL) single-patient-use prefilled pen that delivers a dose in 0.5 mg increments (3).

5. Warnings and Precautions
5.1 Increased Mortality in Patients with Acute Critical Illness
Increased mortality in patients with acute critical illness due to complications following open heart surgery, abdominal surgery or multiple accidental trauma, or those with acute respiratory failure has been reported with somatropin [see Contraindications (4)]. The safety of continuing NGENLA treatment for the approved indication in patients who concurrently develop these illnesses has not been established.
5.2 Severe Hypersensitivity
Severe systemic hypersensitivity reactions including anaphylaxis and angioedema have been reported with somatropin. Inform patients and/or caregivers that such reactions are possible and that prompt medical attention should be sought if an allergic reaction occurs. NGENLA is contraindicated in patients with known hypersensitivity to somatrogon-ghla or any excipients in NGENLA [see Contraindications (4)].
5.3 Increased Risk of Neoplasms
Active Malignancy
There is an increased risk of malignancy progression with somatropin treatment in patients with active malignancy [see Contraindications (4)]. Any preexisting malignancy should be inactive, and its treatment should be completed prior to instituting therapy with NGENLA. Discontinue NGENLA if there is evidence of recurrent malignancy.
Risk of Second Neoplasm in Pediatric Patients
In childhood cancer survivors, who were treated with radiation to the brain/head for their first neoplasm and who developed subsequent GHD and were treated with somatropin, an increased risk of a second neoplasm has been reported. Intracranial tumors, in particular meningiomas, were the most common of these second neoplasms. Monitor all patients with a history of GHD secondary to an intracranial neoplasm while on NGENLA therapy for progression or recurrence of the tumor.
New Malignancy During Treatment
Because children with certain rare genetic causes of short stature have an increased risk of developing malignancies, thoroughly consider the risks and benefits of starting NGENLA in these patients. If treatment with NGENLA is initiated, carefully monitor these patients for development of neoplasms.
Monitor patients on NGENLA therapy carefully for increased growth or potential malignant changes of preexisting nevi. Advise patients and/or caregivers to report marked changes in behavior, onset of headaches, vision disturbances and/or changes in skin pigmentation or changes in the appearance of preexisting nevi.
5.4 Glucose Intolerance and Diabetes Mellitus
Treatment with growth hormone may decrease insulin sensitivity, particularly at higher doses. New onset type 2 diabetes mellitus has been reported in patients receiving growth hormone. Patients with undiagnosed pre-diabetes and diabetes mellitus may experience worsened glycemic control and become symptomatic. Monitor glucose levels periodically in all patients receiving NGENLA, especially in those with risk factors for diabetes mellitus, such as obesity, Turner syndrome, or a family history of diabetes mellitus. Patients with preexisting type 1 or type 2 diabetes mellitus or pre-diabetes should be monitored closely. The doses of antidiabetic agents may require adjustment when NGENLA is initiated.
5.5 Intracranial Hypertension
Intracranial hypertension (IH) with papilledema, visual changes, headache, nausea, and/or vomiting has been reported in patients treated with somatropin. Symptoms usually occurred within the first eight (8) weeks after the initiation of somatropin therapy. In all reported cases, IH-associated signs and symptoms rapidly resolved after cessation of therapy or a reduction of somatropin dose.
Perform fundoscopic examination before initiating treatment with NGENLA to exclude preexisting papilledema and periodically thereafter. If papilledema is identified prior to initiation, evaluate the etiology and treat the underlying cause before initiating NGENLA. NGENLA should be temporarily discontinued in patients with clinical or fundoscopic evidence of IH. If IH is confirmed, restart treatment with NGENLA at a lower dose after IH-associated signs and symptoms have resolved.
5.6 Fluid Retention
Fluid retention during NGENLA therapy may occur. Clinical manifestations of fluid retention (e.g. edema and nerve compression syndromes including carpal tunnel syndrome/paresthesia) are usually transient and dose dependent.
5.7 Hypoadrenalism
Patients receiving growth hormone therapy who have or are at risk for pituitary hormone deficiency(s) may be at risk for reduced serum cortisol levels and/or unmasking of central (secondary) hypoadrenalism. In addition, patients treated with glucocorticoid replacement for previously diagnosed hypoadrenalism may require an increase in their maintenance or stress doses following initiation of NGENLA treatment. Monitor patients for reduced serum cortisol levels and/or need for glucocorticoid dose increases in those with known hypoadrenalism [see Drug Interactions (7)].
5.8 Hypothyroidism
Undiagnosed/untreated hypothyroidism may prevent an optimal response to NGENLA therapy. In patients with GH deficiency, central (secondary) hypothyroidism may first become evident or worsen during treatment with growth hormone therapy. Therefore, patients should have periodic thyroid function tests and thyroid hormone replacement therapy should be initiated or appropriately adjusted when indicated.
5.9 Slipped Capital Femoral Epiphysis
Slipped capital femoral epiphysis may occur more frequently in patients undergoing rapid growth. Evaluate pediatric patients with the onset of a limp or complaints of persistent hip or knee pain.
5.10 Progression of Preexisting Scoliosis
NGENLA increases growth rate, and progression of preexisting scoliosis can occur in patients who experience rapid growth. Growth hormone treatment has not been shown to increase the occurrence of scoliosis. Monitor patients with a history of scoliosis for disease progression.
5.11 Pancreatitis
Cases of pancreatitis have been reported in patients receiving somatropin. The risk may be greater in pediatric patients compared with adults. Consider pancreatitis in patients who develop persistent severe abdominal pain.
5.12 Lipoatrophy
When NGENLA is administered subcutaneously at the same site over a long period of time, lipoatrophy may result. Rotate injection sites when administering NGENLA to reduce this risk [see Dosage and Administration (2.1)].
5.13 Sudden Death in Pediatric Patients with Prader-Willi Syndrome
There have been reports of sudden death after initiating therapy with somatropin in pediatric patients with Prader-Willi syndrome who had one or more of the following risk factors: severe obesity, history of upper airway obstruction or sleep apnea, or unidentified respiratory infection. Male patients with one or more of these factors may be at greater risk than females. NGENLA is not indicated for the treatment of pediatric patients who have growth failure due to genetically confirmed Prader-Willi syndrome.

6.1 Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Safety data are derived from a safety and efficacy study in pediatric patients with GHD [see Clinical Studies (14.1)]. The data from the 12-month main study period reflect exposure of 109 patients to NGENLA administered once weekly (0.66 mg/kg/wk) and 115 patients to somatropin administered once daily (0.034 mg/kg/day).
The mean age across the treatment groups, was 7.7 years (min 3.01, max 11.96); 40.2% of patients were >3 years to ≤7 years, 59.8% were >7 years, 71.9% of patients were male, and 28.1% were female. In this study, 74.6% of patients were White, 20.1% were Asian, 0.9% were Black or African American, 0.5% were American Indian or Alaska Native, 0.5% were Native Hawaiian or Other Pacific Islander, and for 3.6% race information was missing; 10.7% of patients identified as Hispanic or Latino. Baseline disease characteristics were balanced across treatment groups.
Table 1 shows the adverse reactions that occurred in ≥5% of patients treated with NGENLA or daily somatropin during the 12-month main study period. Reporting of injection site reactions was solicited through the use of a patient diary after each weekly injection for patients administered NGENLA and once weekly for patients administered daily injections of somatropin.

7. Drug Interactions
Table 2 includes a list of drugs with clinically significant drug interactions when administered concomitantly with NGENLA and instructions for preventing or managing them.
|
Replacement Glucocorticoid Treatment |
|
|
Clinical Impact: |
Microsomal enzyme 11β-hydroxysteroid dehydrogenase type 1 (11βHSD-1) is required for conversion of cortisone to its active metabolite, cortisol, in hepatic and adipose tissue. Growth hormone inhibits 11βHSD-1. Consequently, individuals with untreated GH deficiency have relative increases in 11βHSD-1 and serum cortisol. Initiation of NGENLA may result in inhibition of 11βHSD-1 and reduced serum cortisol concentrations. |
|
Intervention: |
Patients treated with glucocorticoid replacement for hypoadrenalism may require an increase in their maintenance or stress doses following initiation of NGENLA [see Warnings and Precautions (5.7)]. |
|
Examples: |
Cortisone acetate and prednisone may be affected more than others because conversion of these drugs to their biologically active metabolites is dependent on the activity of 11βHSD-1. |
|
Supraphysiologic Glucocorticoid Treatment |
|
|
Clinical Impact: |
Supraphysiologic glucocorticoid treatment may attenuate the growth-promoting effects of NGENLA in pediatric patients. |
|
Intervention: |
Carefully adjust glucocorticoid replacement dosing in pediatric patients receiving glucocorticoid treatments to avoid hypoadrenalism and an inhibitory effect on growth. |
|
Cytochrome P450-Metabolized Drugs |
|
|
Clinical Impact: |
Limited published data indicate that growth hormone treatment increases cytochrome P450 (CYP450)-mediated antipyrine clearance. NGENLA may alter the clearance of compounds known to be metabolized by CYP450 liver enzymes. |
|
Intervention: |
Careful monitoring is advisable when NGENLA is administered in combination with drugs metabolized by CYP450 liver enzymes. |
|
Oral Estrogen |
|
|
Clinical Impact: |
Oral estrogens may reduce the serum IGF-1 response to NGENLA. |
|
Intervention: |
Patients receiving oral estrogen replacement may require higher NGENLA dosages. |
|
Insulin and/or Other Antihyperglycemic Agents |
|
|
Clinical Impact: |
Treatment with NGENLA may decrease insulin sensitivity, particularly at higher doses. |
|
Intervention: |
Patients with diabetes mellitus may require adjustment of their doses of insulin and/or other antihyperglycemic agents [see Warnings and Precautions (5.4)]. |
8. Use In Specific Populations
8.1 Pregnancy
Risk Summary
There are no available data on NGENLA use in pregnant women to evaluate for a drug associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. In reproduction studies with pregnant rats, there was no evidence of embryo-fetal toxicity following administration of somatrogon-ghla subcutaneously during organogenesis at doses up to 45 times the maximum recommended human dose based on exposure (see Data).
The background risk of major birth defects and miscarriage in the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.
Animal Data
In an embryo-fetal development toxicity study in rats, no adverse maternal or embryo-fetal effects were observed when somatrogon-ghla was administered via subcutaneous injection every 2 days from gestation day (GD) 6 to 18 at doses up to 30 mg/kg (45 times the maximum recommended human dose based on Cav exposure).
In a pre- and postnatal development study in rats, somatrogon-ghla was administered via subcutaneous injection to pregnant rats every 2 days from GD 6 to lactation day 20 at doses up to 30 mg/kg. There was no evidence of maternal toxicity and no adverse effects on the first generation (F1) offspring. Somatrogon-ghla elicited an increase in F1 mean body weights in both sexes and increased the mean copulatory interval in F1 females at the highest dose (30 mg/kg), consistent with a longer estrous cycle length. However, there were no effects on mating indices in F1 females.
8.2 Lactation
Risk Summary
There are no data on the presence of somatrogon-ghla in human or animal milk, the effects on the breastfed infant, or the effects on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for NGENLA and any potential adverse effects on the breastfed infant from NGENLA or from the underlying maternal condition.
8.3 Females and Males of Reproductive Potential
Pregnancy Testing
Although somatrogon-ghla did not interfere with hCG pregnancy testing in a limited number of commercial tests, interference with hCG blood and urine pregnancy testing in patients receiving somatrogon-ghla may be possible, leading to either false positive or false negative results. Alternative methods (i.e., not reliant on hCG) are recommended to determine pregnancy.
8.4 Pediatric Use
The safety and effectiveness of NGENLA have been established for the treatment of growth failure due to inadequate secretion of endogenous growth hormone (GH) in pediatric patients aged 3 years and older [see Clinical Studies (14.1)]. The use of NGENLA for this indication is supported by evidence from a 52‑week, multi-center, randomized, open-label, active-controlled, parallel-group phase 3 study in 224 treatment-naïve, prepubertal pediatric subjects with growth hormone deficiency.
Risks in pediatric patients associated with growth hormone use include:
- •
- Increased risk of second neoplasm in pediatric cancer survivors treated with radiation to the brain and/or head [see Warnings and Precautions (5.3)]
- •
- Slipped capital femoral epiphysis [see Warnings and Precautions (5.9)]
- •
- Progression of preexisting scoliosis [see Warnings and Precautions (5.10)]
- •
- Pancreatitis [see Warnings and Precautions (5.11)]
- •
- Sudden death in pediatric patients with Prader-Willi Syndrome. NGENLA is not indicated for the treatment of pediatric patients with growth failure secondary to genetically confirmed Prader‑Willi syndrome. [see Warnings and Precautions (5.13)]
10. Overdosage
Acute overdosage may lead initially to hypoglycemia and subsequently to hyperglycemia. Overdose with growth hormone may cause fluid retention. Long-term overdosage could result in signs and symptoms of gigantism consistent with the effects of excess growth hormone.
11. Ngenla Description
Somatrogon-ghla, a human growth hormone analog, is a fusion protein produced in Chinese Hamster Ovary (CHO) cells by recombinant DNA technology. It is comprised of the amino acid sequence of human growth hormone (hGH) with one copy of the C-terminal peptide (CTP) from the beta chain of human chorionic gonadotropin (hCG) at the N-terminus and 2 copies of CTP (in tandem) at the C-terminus. Somatrogon-ghla has an approximate molecular weight of 40 KDa.
NGENLA (somatrogon-ghla) injection is a sterile, clear and colorless to slightly light yellow solution for subcutaneous use supplied in a 24 mg/1.2 mL (20 mg/mL) or 60 mg/1.2 mL (50 mg/mL) single-patient-use prefilled pen.
Each 1.2 mL of solution contains either 24 mg or 60 mg of somatrogon-ghla, and the inactive ingredients citric acid monohydrate (0.3 mg), histidine (1.9 mg), metacresol (4 mg, as a preservative), poloxamer 188 (2 mg), sodium chloride (10 mg) and sodium citrate (2.8 mg) in water for injection. NGENLA has a pH of approximately 6.6.
12. Ngenla - Clinical Pharmacology
12.1 Mechanism of Action
Somatrogon-ghla binds to the GH receptor and initiates a signal transduction cascade culminating in changes in growth and metabolism. Somatrogon-ghla binding leads to activation of the STAT5b signaling pathway and increases the serum concentration of Insulin-like Growth Factor (IGF-1). GH and IGF-1 stimulate metabolic changes, linear growth, and enhance growth velocity in pediatric patients with GHD.
12.2 Pharmacodynamics
Following single dose administration of somatrogon, dose-dependent increases in IGF-1 response were observed.
Following multiple dosing, IGF-1 SDS levels were in the normal range for pediatric patients with GHD, similar to daily somatropin. IGF-1 levels peak approximately 2 days (48 hours) post-dose, with the average weekly IGF-1 occurring approximately 4 days post-dose.
12.3 Pharmacokinetics
Somatrogon-ghla pharmacokinetics (PK) was assessed using a population PK approach for NGENLA in 151 pediatric patients (aged 3 to 15.5 years) with GHD.
Absorption
Following subcutaneous injection, serum concentrations increased slowly, peaking 6 to 25 hours with a median of 11 hours after dosing.
In pediatric patients with GHD, somatrogon-ghla exposure increases in a dose-proportional manner for doses of 0.25 mg/kg/wk, 0.48 mg/kg/wk, and 0.66 mg/kg/wk. There is no accumulation of somatrogon-ghla after once weekly administration. In pediatric patients with GHD, the mean population PK estimated steady-state peak concentrations (mean ± SD) following 0.66 mg/kg/wk was 495 ± 90 ng/mL.
Distribution
In pediatric patients with GHD, the mean population PK estimated apparent central volume of distribution was 0.342 L/kg and apparent peripheral volume of distribution was 0.671 L/kg.
Elimination
In pediatric patients with GHD, the mean population PK estimated apparent clearance was 0.0398 L/h/kg. The mean population PK estimated effective half-life was 37.7 hours, which allows for weekly dosing. Somatrogon-ghla will be present in the circulation for about 8 days after the last dose.
Specific Populations
Based on population PK analyses, age, sex, race, and ethnicity do not have a clinically meaningful effect on the pharmacokinetics of somatrogon-ghla in pediatric patients with GHD. The exposure of somatrogon-ghla decreases with an increase in body weight. However, the somatrogon-ghla dosing regimen of 0.66 mg/kg/wk provides adequate systemic exposure over the body weight range of 10 to 54 kg evaluated in the clinical studies.
12.6 Immunogenicity
The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies in the studies described below with the incidence of anti-drug antibodies in other studies, including those of somatrogon or other growth hormone products.
During the 12-month main period of study NCT 02968004, 84/109 (77.1%) of somatrogon-ghla‑treated patients tested positive for anti-drug antibodies, with most showing specificity to human growth hormone. The anti-drug antibodies persisted in most of the subjects during the study. Neutralizing antibodies developed in 8/217 (3.7%) of somatrogon-ghla-treated patients during the study for up to 42 months of exposure to somatrogon-ghla. The neutralizing antibodies were transient in all subjects. Anti-drug antibodies, including neutralizing-antibodies, did not appear to have a clinically significant impact on the safety or effectiveness of NGENLA during the 12‑month randomized treatment period. Additionally, no apparent effect of anti-drug antibodies on growth was observed for additional 30 months of exposure to somatrogon-ghla in the uncontrolled extension period of study NCT 02968004.
Anti-Drug Antibody Effects on Pharmacokinetics
The population pharmacokinetic analysis of data from study NCT 02968004 showed that patients who tested positive for anti-drug antibodies had an approximately 26% decrease in apparent clearance. These anti-drug antibody-associated pharmacokinetic changes are not considered to be clinically significant.
13. Nonclinical Toxicology
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
Impairment of Fertility
The potential for somatrogon-ghla to affect fertility and early embryonic development was evaluated in male and female rats administered subcutaneously before cohabitation, through mating to implantation. Somatrogon‑ghla elicited an increase in estrous cycle length, copulatory interval, and number of corpora lutea at exposures ≥22-fold the MRHD, but there was no impact on female fertility, mating indices, number of viable embryos or early embryonic development, or on male fertility up to 30 mg/kg every two days (45-fold the MRHD based on exposure).
14. Clinical Studies
14.1 Treatment-Naïve Pediatric Patients with Growth Hormone Deficiency
A multi-center, randomized, open-label, active-controlled, parallel-group phase 3 study (NCT 02968004) was conducted in 224 treatment-naïve, prepubertal pediatric subjects with growth hormone deficiency (GHD). The primary efficacy endpoint was annualized height velocity at Week 52.
One hundred nine (109) subjects received 0.66 mg/kg/week NGENLA, and 115 subjects received 0.034 mg/kg/day daily somatropin. The subjects age ranged from 3 to 12 years, with a mean of 7.7 years. One hundred sixty-one (71.9%) subjects were male and 63 (28.1%) were female. One hundred sixty-seven (74.6%) subjects were White, 45 (20.1%) subjects were Asian, 2 (0.9%) subjects were Black or African-American, 1 (0.5%) subject was American Indian or Alaska Native, 1 (0.5%) subject was Native Hawaiian or Other Pacific Islander, and for 8 (3.6%) subjects race information was missing; 24 (10.7%) subjects identified as Hispanic or Latino. The subjects had a mean baseline height standard deviation score (SDS) of -2.9.
Treatment with once-weekly NGENLA for 52 weeks resulted in an annualized height velocity of 10.1 cm/year. Patients treated with daily somatropin achieved an annualized height velocity of 9.8 cm/year after 52 weeks of treatment. Refer to Table 3.
| Abbreviations: CI=confidence interval; LSM=least square mean; N=number of patients randomized and treated | |||
| The estimates of LSM are from analysis of covariance model with treatment, age group, gender, peak growth hormone levels, and region as fixed factors and baseline height SDS as a covariate. Missing data is imputed by multiple imputation using SAS PROC MI with MNAR/FCS Method. | |||

Is this pen new?
Yes: Go to new pen set up
No
New pen set up (priming) – for the first use of a new pen only
You must set up each new pen (priming) before using it for the first time
- •
- New pen set up is done before each new pen is used for the first time.
- •
- The purpose of setting up a new pen is to remove air bubbles and make sure you get the correct dose.
Important: Skip Step-A through to Step-C if you have already set up your pen.
A - Set priming dose
- •
- Turn the dose knob to 0.4.
- o
- This is the amount to prime the pen.
- Note: If you turn the dose knob too far, you can turn it back.
B - Tap cartridge holder
- •
- Hold the pen with the needle pointing up so that the air bubbles can rise.
- •
-
Tap the cartridge holder gently to float any air bubbles to the top.
Important: Follow Step-B even if you do not see air bubbles.
C - Press button and check for liquid
- •
- Press the injection button until it cannot go any further and "0" is shown in the dose window.
- •
- Check for liquid at the needle tip. If liquid appears, your pen is set up.
- •
- Always make sure that a drop of liquid appears before you inject. If liquid has not appeared, repeat Step-A through to Step-C.
- o
- If liquid does not appear after you have repeated Step-A through Step-C five (5) times, attach a new needle and try 1 more time. Do not use the pen if a drop of liquid still does not appear. Contact your healthcare provider or pharmacist and use a new pen.
Setting your prescribed dose
Step 7 - Set your dose
3.8 mg shown in the dose window
12.0 mg shown in the dose window
- •
- Turn the dose knob to set your dose.
- o
- The dose can be increased or decreased by turning the dose knob in either direction.
- o
- The dose knob turns 0.2 mg at a time.
- o
- Your pen contains 24 mg of medicine but you can only set a dose of up to 12 mg for a single injection.
- o
- The dose window shows the dose in mg. See Examples A and B.
- •
-
Always check the dose window to make sure you have set the correct dose.
Important: Do not press the injection button while setting your dose.
What should I do if I cannot set the dose I need?
- •
- If your dose is more than 12 mg you will need to split your dose into more than 1 injection.
- •
- You can give from 0.2 mg to 12 mg in a single injection.
- o
- Use a new needle for each injection (See Step 4: Attach needle).
- o
- If you normally need to give 2 injections for your full dose, be sure to give your second dose.
What should I do if I do not have enough medicine left in my pen?
- •
- If your pen contains less than 12 mg of medicine, the dose knob will stop with the remaining amount of medicine shown in the dose window.
- •
- If there is not enough medicine left in your pen for your full dose, you may either:
- o
- Inject the amount left in your pen, then prepare a new pen to complete your dose in full. Remember to subtract the dose you have already received. For example, if the dose is 3.8 mg and you can only set the dose knob to 1.8 mg, you should inject another 2.0 mg with a new pen.
- o
- Or get a new pen and inject the full dose.
Only split your dose if you have been trained or told by your healthcare provider on how to do this.
Injecting your dose
Step 8 - Insert the needle
- •
- Hold your pen so you can see the numbers in the dose window.
- •
- Insert the needle straight into your skin.
Step 9 - Inject your medicine
- •
- Keep holding the needle in the same position in your skin.
- •
- Press the injection button until it cannot go any further and "0" is shown in the dose window.
Step 10 - Count to 10
- •
- Continue to press the injection button while counting to 10. Counting to 10 will allow the full dose of medicine to be given.
- •
- After counting to 10, let go of the injection button and slowly remove the pen from the injection site by pulling the needle straight out.
Note: You may see a drop of medicine at the needle tip. This is normal and does not affect the dose you just received.
Step 11 - Attach outer needle cover
- •
- Carefully place the outer needle cover back on the needle.
- •
- Press on the outer needle cover until it is secure.
Caution: Never try to put the inner needle cap back on the needle. You may prick yourself with the needle.
Step 12 - Remove the needle
- •
- Unscrew the capped needle from the pen.
- •
- Gently pull until the capped needle comes off.
Note: If the needle is still on, replace the outer needle cover and try again. Be sure to apply pressure when unscrewing the needle. - •
- Throw away the needle in the FDA-cleared sharps container (See How should I dispose of the pen needles and pens?).
- •
- Important: Always remove and throw away used needles. Do not reuse needles.
Step 13 - Replace the pen cap
- •
- Replace the pen cap back onto your pen.
- •
- Do not recap the pen with a needle attached.
- •
- If there is any medicine left in your pen, store in the refrigerator between uses (See How should I store my pen?).
Step 14 - After your injection
- •

Is this pen new?
Yes: Go to new pen set up
No
New pen set up (priming) – for the first use of a new pen only
You must set up each new pen (priming) before using it for the first time
- •
- New pen set up is done before each new pen is used for the first time.
- •
- The purpose of setting up a new pen is to remove air bubbles and make sure you get the correct dose.
Important: Skip Step-A through to Step-C if you have already set up your pen.
A - Set priming dose
- •
- Turn the dose knob to 1.0.
- o
- This is the amount to prime the pen.
- Note: If you turn the dose knob too far, you can turn it back.
B - Tap cartridge holder
- •
- Hold the pen with the needle pointing up so that the air bubbles can rise.
- •
-
Tap the cartridge holder gently to float any air bubbles to the top.
Important: Follow Step-B even if you do not see air bubbles.
C - Press button and check for liquid
- •
- Press the injection button until it cannot go any further and "0" is shown in the dose window.
- •
- Check for liquid at the needle tip. If liquid appears, your pen is set up.
- •
- Always make sure that a drop of liquid appears before you inject. If liquid has not appeared, repeat Step-A through to Step-C.
- o
- If liquid does not appear after you have repeated Step-A through Step-C five (5) times, attach a new needle and try 1 more time. Do not use the pen if a drop of liquid still does not appear. Contact your healthcare provider or pharmacist and use a new pen.
Setting your prescribed dose
Step 7 - Set your dose
21.5 mg shown in the dose window
30.0 mg shown in the dose window
- •
- Turn the dose knob to set your dose.
- o
- The dose can be increased or decreased by turning the dose knob in either direction.
- o
- The dose knob turns 0.5 mg at a time.
- o
- Your pen contains 60 mg of medicine but you can only set a dose of up to 30 mg for a single injection.
- o
- The dose window shows the dose in mg. See Examples A and B.
- •
-
Always check the dose window to make sure you have set the correct dose.
Important: Do not press the injection button while setting your dose.
What should I do if I cannot set the dose I need?
- •
- If your dose is more than 30 mg you will need to split your dose into more than 1 injection.
- •
- You can give from 0.5 mg to 30 mg in a single injection.
- o
- Use a new needle for each injection (See Step 4: Attach needle).
- o
- If you normally need to give 2 injections for your full dose, be sure to give your second dose.
What should I do if I do not have enough medicine left in my pen?
- •
- If your pen contains less than 30 mg of medicine, the dose knob will stop with the remaining amount of medicine shown in the dose window.
- •
- If there is not enough medicine left in your pen for your full dose, you may either:
- o
- Inject the amount left in your pen, then prepare a new pen to complete your dose in full. Remember to subtract the dose you have already received. For example, if the dose is 21.5 mg and you can only set the dose knob to 17 mg, you should inject another 4.5 mg with a new pen.
- o
- Or get a new pen and inject the full dose.
Only split your dose if you have been trained or told by your healthcare provider on how to do this.
Injecting your dose
Step 8 - Insert the needle
- •
- Hold your pen so you can see the numbers in the dose window.
- •
- Insert the needle straight into your skin.
Step 9 - Inject your medicine
- •
- Keep holding the needle in the same position in your skin.
- •
- Press the injection button until it cannot go any further and "0" is shown in the dose window.
Step 10 - Count to 10
- •
- Continue to press the injection button while counting to 10. Counting to 10 will allow the full dose of medicine to be given.
- •
- After counting to 10, let go of the injection button and slowly remove the pen from the injection site by pulling the needle straight out.
Note: You may see a drop of medicine at the needle tip. This is normal and does not affect the dose you just received.
Step 11 - Attach outer needle cover
- •
- Carefully place the outer needle cover back on the needle.
- •
- Press on the outer needle cover until it is secure.
Caution: Never try to put the inner needle cap back on the needle. You may prick yourself with the needle.
Step 12 - Remove the needle
- •
- Unscrew the capped needle from the pen.
- •
- Gently pull until the capped needle comes off.
Note: If the needle is still on, replace the outer needle cover and try again. Be sure to apply pressure when unscrewing the needle. - •
- Throw away the needle in the FDA-cleared sharps container (See How should I dispose of the pen needles and pens?).
- •
- Important: Always remove and throw away used needles. Do not reuse needles.
Step 13 - Replace the pen cap
- •
- Replace the pen cap back onto your pen.
- •
- Do not recap the pen with a needle attached.
- •
- If there is any medicine left in your pen, store in the refrigerator between uses (See How should I store my pen?).
Step 14 - After your injection
- •
- Press lightly on the injection site with a clean cotton ball or gauze pad, and hold for a few seconds.
- •
- Do not rub the injection site. You may have slight bleeding. This is normal.
- •
- You may cover the injection site with a small adhesive bandage, if needed.
- •
- If your pen is empty or it has been more than 28 days after first use, throw it away even if it contains unused medicine. See Storage and disposal on the right side of this leaflet.
