HUMIRA is a medication that is taken by injection. And once your doctor shows you how to take HUMIRA, the injections can be taken in the convenience of your own home. After your initial starting doses, you only need to take one injection of HUMIRA every other week.

HUMIRA is a biologic disease-modifying antirheumatic drug, also called a biologic DMARD, or simply "biologic." Biologics are a class of advanced medications used to treat the signs and symptoms of active psoriatic arthritis, improve physical function and help keep the joint damage from getting worse. Other biologic DMARDs include ENBREL® (etanercept) and REMICADE® (infliximab).

Yes, you can take other medicines if your doctor has prescribed them, or has told you it's okay to take them while you're taking HUMIRA. It's important that you tell your doctor about any other medicines you are taking for other conditions (for example, high blood pressure medicine) before you start taking HUMIRA. You also should tell your doctor about any over-the-counter drugs, painkillers, herbal medicines, and vitamin and mineral supplements you're taking.

Crohn's disease is a lifelong inflammatory bowel disease (IBD). Parts of the digestive tract get swollen and have deep sores called ulcers. Crohn's disease usually is found in the last part of the small intestine and the first part of the large intestine. But it can develop anywhere in the digestive tract, from the mouth to the anus.

HUMIRA is a biologic disease-modifying antirheumatic drug, also called a biologic DMARD, or simply "biologic." Biologics are a class of advanced medications approved for reducing the signs and symptoms of active AS. Other biologic DMARDs include ENBREL® (etanercept) and REMICADE® (infliximab). ENBREL is self-injected and REMICADE requires a visit to a health care professional to administer the medication by intravenous infusion (IV).

A malfunction in the immune system is certainly a part of Crohn's disease. This may be an inability to "turn off" the immune system after it "turns on" for an appropriate reason. Or, the immune system may "turn on" for the wrong reason. Immunosuppressive medications used to keep individuals from rejecting transplanted organs have been shown to be effective in treating Crohn's disease. These factors have led many researchers to characterize Crohn's disease as autoimmune.

Unfortunately, there are no current treatments available that can cure psoriatic arthritis. However, HUMIRA is a disease-modifying medicine that can control inflammation. It treats the disease by relieving the pain and inflammation as well as the skin lesions.

Gastroesophageal reflux disease (GERD) develops when stomach acid and juices back up, or reflux, into the esophagus, the muscular tube that connects the throat to the stomach. This happens when the valve between the lower end of the esophagus and the stomach (the lower esophageal sphincter) does not close tightly enough. GERD most commonly occurs when the lower esophageal sphincter relaxes at the wrong time (that is, when you are not swallowing) and remains open too long.

Crohn's disease is very rarely life threatening. Normally, Crohn's disease is a chronic, lifelong illness characterized by sporadic flare-ups separated by periods of remission. Occasionally, a complication such as a severe abscess or a large fistula connecting the intestine to another internal organ can set the stage for a life-threatening infection. In addition, Crohn's disease may require surgery; all surgical procedures involve the risk of life-threatening complications.

Doctors don't know what causes Crohn's disease. You may get it when the body's immune system has an abnormal response to normal bacteria in your intestine. Other kinds of bacteria and viruses may also play a role in causing the disease. Crohn's disease can run in families. Your chances of getting it are higher if a close family member has it. People of Eastern European (Ashkenazi) Jewish family background may have a higher chance of getting Crohn's disease.
