What is Humira Pen (adalimumab)?
Adalimumab reduces the effects of a substance in the body that can cause inflammation.
Adalimumab is used to treat rheumatoid arthritis, juvenile idiopathic arthritis, psoriatic arthritis, ankylosing spondylitis, plaque psoriasis, and a chronic skin condition called hidradenitis suppurativa. It is also used to treat Crohn's disease or ulcerative colitis, after other drugs have been tried without successful treatment of symptoms.
Adalimumab may also be used for purposes not listed in this medication guide.
What is the most important information I should know about Humira Pen (adalimumab)?
Some people using adalimumab have developed a rare fast-growing type of lymphoma (cancer), which can be fatal. Adalimumab can also lower blood cells that help your body fight infections and help your blood to clot. Serious and sometimes fatal infections may occur.
Call your doctor at once if you have symptoms such as fever, night sweats, weight loss, feeling full after eating only a small amount, pain in your upper stomach, easy bruising or bleeding, dark urine, or jaundice (yellowing of the skin or eyes).
What should I discuss with my healthcare provider before using Humira Pen (adalimumab)?
You should not use this medicine if you are allergic to adalimumab, or if you have an active infection.
Some people using adalimumab have developed a rare fast-growing type of lymphoma (cancer). This condition affects the liver, spleen, and bone marrow, and it can be fatal. This has occurred mainly in teenagers and young adults using adalimumab or similar medicines to treat Crohn's disease or ulcerative colitis. However, people with autoimmune disorders may have a higher risk of lymphoma.
Before you use adalimumab, your doctor may perform tests to make sure you do not have tuberculosis or other infections. To make sure adalimumab is safe for you, tell your doctor if you have:
recent or chronic infections;
past or present cancer;
a history of hepatitis B;
congestive heart failure;
an allergy to latex rubber;
any numbness or tingling, or a nerve-muscle disorder such as multiple sclerosis or Guillain-Barre syndrome; or
if anyone in your household has tuberculosis, or if you have recently traveled to an area where tuberculosis is common.
Some infections are more likely to occur in certain areas of the world. Tell your doctor where you live and where you have recently traveled or plan to travel to during treatment.
Adalimumab is not expected to harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment.
It is not known whether adalimumab passes into breast milk or if it could harm a nursing baby. Tell your doctor if you are breast-feeding a baby.
Adalimumab should not be given to a child younger than 2 years old (or 6 years old if treating Crohn's disease). Children using adalimumab should be current on all childhood immunizations before starting treatment.
Using this medicine may increase your risk of certain types of cancer, such as lymphoma (cancer of the lymph nodes), or melanoma (a tumor that usually affects the skin). You may also develop an autoimmune disorder such as a lupus-like syndrome. Talk with your doctor about your specific risk.
How should I use Humira Pen (adalimumab)?
Follow the directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended. Use adalimumab regularly to get the most benefit. Get your prescription refilled before you run out of medicine completely.
The dose schedule for adalimumab is highly variable and depends on the condition you are treating. You may need an injection only every other week. Or you may need up to 4 injections in 1 day for 2 days in a row. Follow your doctor's dosing instructions very carefully.
Do not start using adalimumab if you have any signs of an infection (fever, chills, night sweats, weight loss, body aches, tiredness, cough with mucus, feeling short of breath, skin sores, stomach pain, diarrhea, pain or burning when you urinate). Call your doctor for instructions.
Adalimumab is injected under the skin. You may be shown how to use injections at home. Do not self inject this medicine if you do not fully understand how to give the injection and properly dispose of used needles and syringes. Do not inject adalimumab into skin that is bruised, red, tender, or hard.
Each adalimumab prefilled syringe is for one use only. Throw away after one use, even if there is still some medicine left in it after injecting your dose. Do not use a prefilled syringe if the medicine if it looks cloudy or has particles in it. Call your pharmacist for new medicine.
Use a disposable needle and syringe only once. Follow any state or local laws about throwing away used needles and syringes. Use a puncture-proof "sharps" disposal container (ask your pharmacist where to get one and how to throw it away). Keep this container out of the reach of children and pets.
Adalimumab can lower blood cells that help your body fight infections and help your blood to clot. This can make it easier for you to bleed from an injury or get sick from being around others who are ill. Your blood may need to be tested often. Serious and sometimes fatal infections may occur during treatment with adalimumab. Contact your doctor right away if you have signs of infection such as: fever, chills, sore throat, or flu symptoms.
If you need surgery, tell the surgeon ahead of time that you are using adalimumab.
If you have ever had hepatitis B, adalimumab can cause this condition to come back or get worse. You will need frequent blood tests to check your liver function during treatment and for several months after you stop using this medicine.
Store in a refrigerator. If you travel with a prefilled syringe, keep it in a small cooler with an ice pack and protect it from light. Do not remove the prefilled syringe from the refrigerator or cooler until you are ready to give yourself an injection.
Do not freeze adalimumab, and throw away the medicine if it has become frozen.
What happens if I miss a dose?
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 the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while using Humira Pen (adalimumab)?
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 adalimumab. 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), zoster (shingles), and nasal flu (influenza) vaccine.
