Precautions
The US FDA requires a Risk Evaluation and Mitigation Strategy (REMS) for pramlintide. It includes communication plan. For additional information: www.fda.gov/REMS
BOXED WARNING(S):
- Use with insulin has been associated with an increased risk of severe hypoglycemia, particularly in patients with type 1 diabetes.
- Hypoglycemia risk may be reduced by appropriate patient selection, careful patient instruction, and insulin dose reduction.
Safety and efficacy have not been established in patients younger than 18 years.
Consult WARNINGS section for additional precautions.

Other Comments
Administration advice:
- This drug should be administered subcutaneously immediately prior to each major meal (greater than or equal to 250 kcal or containing greater than or equal to 30 grams of carbohydrate).
- Each dose should be administered subcutaneously into the abdomen or thigh; administration into the arm is not recommended.
- Injection sites should be rotated so that the same site is not used repeatedly.
- Never share an insulin pen between patients, even if the needle is changed; do not reuse or share needles between patients as this presents a risk for transmission of blood-borne pathogens
- The injection site selected should be different from the site chosen for any concomitant insulin injection.
- Pramlintide and insulin should be administered as separate injections.
- This drug should not be mixed with any type of insulin.
- If a dose is missed, wait until the next scheduled dose and administer the usual amount.
