Infections have also been reported in patients receiving HUMIRA alone. Treatment with HUMIRA should not be initiated in patients with active infections. TNF-blocking agents, including HUMIRA, have been associated with reactivation of hepatitis B (HBV) in patients who are chronic carriers of this virus. Some cases have been fatal. Patients at risk for HBV infections should be evaluated for prior evidence of HBV infections before initiating HUMIRA. The combination of HUMIRA and anakinra is not recommended and patients using HUMIRA should not receive live vaccines.

More cases of malignancies have been observed among patients receiving TNF blockers, including HUMIRA, compared to control patients in clinical trials. These malignancies, other than lymphoma and non-melanoma skin cancer, were similar in type and number to what would be expected in the general population. There was an approximately 3.0 fold higher rate of lymphoma in combined controlled and uncontrolled open-label portions of HUMIRA clinical trials. The potential role of TNF-blocking therapy in the development of malignancies is not known. TNF-blocking agents, including HUMIRA, have been associated in rare cases with demyelinating disease and severe allergic reactions. Infrequent reports of serious blood disorders have been reported with TNF-blocking agents.

Worsening congestive heart failure (CHF) has been observed with TNF-blocking agents, including HUMIRA, and new onset CHF has been reported with TNF-blocking agents. Treatment with HUMIRA may result in the formation of autoantibodies and rarely, in development of a lupus-like syndrome.

The most frequent adverse events seen in the placebo-controlled clinical trials in adults with rheumatoid arthritis (HUMIRA vs. placebo) were injection site reactions (20 percent vs. 14 percent),
