Hi,
Adalimumab (brand name HUMIRA) is a TNF inhibitor which has been shown to reduce the signs and symptoms of psoriatic arthritis (PsA) in adults, alone or with certain other medicines.
Adalimumab is an immunosuppressant, and as such has a number of serious safety concerns, potentially fatal, typical of the TNF class. According to the product labeling, after a number of studies and reports of adverse events in patients receiving adalimumab, including serious and sometimes fatal blood disorders; serious infections including include TB (tuberculosis) and infections caused by viruses, fungi, or bacteria; rare reports of lymphoma and solid tissue cancers; rare reports of serious liver injury; and rare reports of demyelinating central nervous system disorders); rare reports of cardiac failure; the U.S. Food and Drug Administration issued a black box warning to doctors appearing in the product labeling of adalimumab and the other TNF drugs instructing them to screen and monitor potential patients more carefully.

You have to take it only under medical supervision and not self-medicate with drug.
At the first sign of any of the adverse effects mentioned .stop taking it and report to the doctor immediately.
