Yuflyma (adalimumab-aaty) is a biosimilar of Humira; it is a TNF alfa inhibitor used to reduce pain, inflammation, and skin symptoms in autoimmune conditions.  Yuflyma is used to treat rheumatoid arthritis, juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, Crohn's disease, ulcerative colitis, plaque psoriasis, and hidradenitis suppurativa. 

Yuflyma is a biosimilar to Humira, biosimilars are biologic medicines that are a very close copy to the original product made by another company. It is not an interchangeable biosimilar. Yuflyma is available as a high-concentration and citrate-free formulation and can be given using a prefilled syringe or an autoinjector.

Yuflyma affects your immune system. You may get infections more easily, even serious or fatal infections.

Before or during treatment with Yuflyma, tell your doctor if you have signs of infection such as fever, chills, aches, tiredness, cough, skin sores, diarrhea, or burning when you urinate.

Your doctor should test you for tuberculosis (TB) before starting to take Yuflyma and also monitor you closely for signs and symptoms of TB during treatment.

The chances of getting cancer may be increased for children and adults taking TNF-blockers.

Use Yuflyma exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Yuflyma is injected under the skin (subcutaneous injection) using an autoinjector or a prefilled syringe.

The dose schedule for Yuflyma depends on the severity and the condition you are treating. Follow your doctor's dosing instructions very carefully.

A healthcare provider will teach you how to use Yuflyma by yourself properly. Do not use Yuflyma if you do not fully understand the instructions for proper use. Ask your doctor or pharmacist if you have any questions.

Do not use this medicine if you have any signs of an infection. Call your doctor for instructions.

Prepare your injection only when you are ready to give it. Do not use it if the medicine looks cloudy, has changed color, or has particles in it. Call your pharmacist for new medicine.

Leave the Auto-injector or Prefilled Syringe at room temperature 68°F to 77°F (20°C to 25°C) for 15 to 30 minutes to allow it to warm up.  Do not warm the Prefilled Syringe using heat sources such as hot water or a microwave.

Choose an injection site. You may inject into the front of your thighs and your abdomen except for the 2 in (5 cm) around the belly button (navel). Rotate the injection site each time you give an injection. Each new injection site should be at least 1.2 in (3 cm) away from the injection site you used before.

Do NOT inject in the red, hard, tender, damaged, bruised, or scarred skin, and do NOT inject through your clothes.

Yuflyma affects your immune system so you may get infections more easily, even serious or fatal infections. Your doctor will need to examine you on a regular basis.

Use a needle and syringe only once, then place them in a puncture-proof "sharps" container. Follow state or local laws about how to dispose of this container. Keep it out of the reach of children and pets.

The dose and frequency of Yuflyma given are dependent on age, severity, and condition treated. For more information on specific dosing schedules, click the link below.

• Yuflyma Prefilled Auto-injector (Yuflyma AI): 40 mg/0.4 mL
• Yuflyma Prefilled syringe with safety guard: 40 mg/0.4 mL

Before you start using Yuflyma, tell your doctor if you have signs of infection--fever, chills, sweats, muscle aches, tiredness, cough, bloody mucus, skin sores, diarrhea, burning when you urinate, or feeling constantly tired.

Yuflyma should only be used in age groups for the specific conditions that Yuflyma is FDA-approved to treat. Children using Yuflyma should be current on all childhood immunizations before starting treatment.

Tell your doctor if you have ever had:

• tuberculosis (or if anyone in your household has tuberculosis);
• a chronic infection;
• cancer;
• hepatitis B (Yuflyma can cause hepatitis B to come back or get worse);
• diabetes;
• heart failure;
• any numbness or tingling, or a nerve-muscle disorder such as multiple sclerosis or Guillain-Barre syndrome;
• an allergy to latex rubber;
• if you are scheduled to have major surgery; or
• if you have recently received or are scheduled to receive any vaccine.

Tell your doctor where you live and if you have recently traveled or plan to travel. You may be exposed to infections that are common in certain areas of the world.

Yuflyma may cause a rare type of lymphoma (cancer) of the liver, spleen, and bone marrow that can be fatal. This has occurred mainly in teenagers and young men with Crohn's disease or ulcerative colitis. However, anyone with an inflammatory autoimmune disorder may have a higher risk of lymphoma. Talk with your doctor about your own risk.

Pregnancy

It is not known whether Yuflyma will harm an unborn baby. Tell your doctor if you are pregnant or planning a pregnancy. Make sure any doctor caring for your newborn baby knows if you used Yuflyma while you were pregnant, and especially before your baby receives any vaccines.

Breastfeeding

It may not be safe to breastfeed a baby while using Yuflyma. Ask your doctor about any risks and the best way to feed your baby while on Yuflyma.

Use the medicine as soon as you remember, and then go back to your regular injection schedule. Do not use extra medicine to make up for the missed dose.

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

Do not inject into skin that is bruised, red, tender, or hard.

Avoid being near people who are sick or have infections. Tell your doctor at once if you develop signs of infection.

Do not receive a "live" vaccine while using Yuflyma. The vaccine may not work as well during this time, and may not fully protect you from disease. Live vaccines include measles, mumps, rubella (MMR), polio, rotavirus, typhoid, yellow fever, varicella (chickenpox), or zoster (shingles).
