Humira

Humira is a prescription medication used to relieve the symptoms of certain autoimmune disorders. It is used to treat certain kinds of arthritis, ankylosing spondylitis, Crohn's disease, plaque psoriasis, ulcerative colitis and hidradenitis suppurativa (a chronic inflammatory skin disease). 

Humira is in a class of medications called tumor necrosis factor (TNF) inhibitors. It works by blocking the action of TNF, a substance in the body that causes inflammation. 

This medication comes in an injectable form in prefilled syringes. Humira is injected just under the skin usually once every other week.

Common side effects of Humira include reactions at the injection site, sinus infections, and headaches.

Humira is a prescription medication used to:

• Reduce the signs and symptoms of:
  • moderate to severe rheumatoid arthritis (RA) in adults. Humira can be used alone, with methotrexate, or with certain other medicines.
  • moderate to severe polyarticular juvenile idiopathic arthritis (JIA) in children 2 years and older. Humira can be used alone, with methotrexate, or with certain other medicines. It is recommended that JIA patients should be up to date with appropriate vaccinations before starting Humira. Those taking Humira may receive vaccinations except for live ones.
  • psoriatic arthritis (PsA) in adults. Humira can be used alone or with certain other medicines.
  • ankylosing spondylitis (AS) in adults.
  • moderate to severe Crohn’s disease (CD) in adults and children when other treatments have not worked well enough.
  • moderate to severe hidradenitis suppurativa (HS) in adults.
  • moderate to severe ulcerative colitis (UC)
  • non-infectious intermediate, posterior and panuveitis (UV) in adults
• Treat moderate to severe chronic (lasting a long time) plaque psoriasis (Ps) in adults who have the condition in many areas of their body and who may benefit from taking injections or pills (systemic therapy) or phototherapy (treatment using ultraviolet light alone or with pills).
• Treat moderate to severe ulcerative colitis in adults who have not been helped by corticosteroids and other immunosuppressant medicines.

This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information.

Humira is a medicine that affects your immune system. Humira can lower the ability of your immune system to fight infections. Serious infections have happened in people taking Humira. These serious infections include tuberculosis (TB) and infections caused by viruses, fungi or bacteria that have spread throughout the body. Some people have died from these infections.

• Your doctor should test you for TB before starting Humira.
• Your doctor should check you closely for signs and symptoms of TB during treatment with Humira.

You should not start taking Humira if you have any kind of infection unless your doctor says it is okay.

Cancer

• For children and adults taking TNF-blockers, including Humira, the chances of getting cancer may increase.
• There have been cases of unusual cancers in children, teenagers, and young adults using TNF-blockers.
• People with RA, especially more serious RA, may have a higher chance of getting a kind of cancer called lymphoma.
• If you use TNF blockers including Humira your chance of getting two types of skin cancer may increase (basal cell cancer and squamous cell cancer of the skin). These types of cancer are generally not life-threatening if treated. Tell your doctor if you have a bump or open sore that doesn’t heal.
• Some people receiving TNF blockers including Humira developed a rare type of cancer called hepatosplenic T-cell lymphoma. This type of cancer often results in death. Most of these people were male teenagers or young men. Also, most people were being treated for Crohn’s disease or ulcerative colitis with another medicine called Imuran (azathioprine) or Purinethol (6-mercaptopurine).

Medications can interact with certain foods. In some cases, this may be harmful and your doctor may advise you to avoid certain foods.

• have recently received or are scheduled to receive a vaccine. You may receive vaccines, except for live vaccines while using Humira.
• Children with juvenile idiopathic arthritis should be brought up to date with all vaccines before starting Humira.
• are allergic to rubber or latex. The needle cover on the prefilled syringe contains dry natural rubber. Tell your doctor if you have any allergies to rubber or latex.
• are allergic to Humira or to any of its ingredients.
• are pregnant or planning to become pregnant. It is not known if Humira will harm your unborn baby. Humira should only be used during a pregnancy if needed. 
  Pregnancy Registry: Abbott Laboratories has a registry for pregnant women who take Humira. The purpose of this registry is to check the health of the pregnant mother and her child. Talk to your doctor if you are pregnant and contact the registry at 1–877–311–8972.
• breastfeeding or plan to breastfeed. You and your doctor should decide if you will breastfeed or use Humira. You should not do both.

Tell your doctor about all the medicines you take, including prescription and non-prescription medicines, vitamins, and herbal supplements.

Tell your doctor if you are pregnant or planning to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Humira falls into category B. Humira can cross the placenta during the third trimester of pregnancy. No harm was observed in studies performed in pregnant animals. Because animal studies cannot always predict how these medications may affect humans, Humira should be used during pregnancy only if clearly needed.

Tell your doctor if you are breastfeeding or planning to breastfeed. It is not known if Humira is excreted in human breast milk or if it will harm your nursing baby.

Humira is given by an injection under the skin. Your doctor will tell you how often to take an injection of Humira. This is based on your condition to be treated. Do not inject Humira more often than you were prescribed. See the Patient Instructions for Use inside the carton for complete instructions for the right way to prepare and inject Humira.

Make sure you have been shown how to inject Humira before you do it yourself. You can call your doctor or 1-800-4Humira (1-800-448-6472) if you have any questions about giving yourself an injection. Someone you know can also help you with your injection after he/she has been shown how to prepare and inject Humira. Do not try to inject Humira yourself until you have been shown the right way to give the injections. If your doctor decides that you or a caregiver may be able to give your injections of Humira at home, you should receive training on the right way to prepare and inject Humira.

Do not miss any doses of Humira unless your doctor says it is okay. If you forget to take Humira, inject a dose as soon as you remember. Then, take your next dose at your regular scheduled time. This will put you back on schedule. In case you are not sure when to inject Humira, call your doctor or pharmacist.

If you take more Humira than you were told to take, call your doctor.

Take Humira exactly as it is prescribed by your doctor. Your doctor will determine the best dose for you.

The recommended dose of Humira is 80 mg initial dose, followed by 40 mg every other week starting one week after initial dose.

If you take too much Humira, call your healthcare provider or local Poison Control Center, or seek emergency medical attention right away.
