Nabi-HB is available in generic form. Common side effects of Nabi-HB include:

SIDE EFFECTS
Fifty male and female volunteers received Nabi-HB, Hepatitis B Immune Globulin (Human), intramuscularly in pharmacokinetics trials20. The number of patients with reactions related to the administration of Nabi-HB included local reactions such as erythema 6 (12percent) and ache 2 (4percent) at the injection site, as well as systemic reactions such as headache 7 (14percent), myalgia 5 (10percent), malaise 3 (6percent), nausea 2 (4percent), and vomiting 1 (2percent). The majority (92percent) of reactions were reported as mild. The following adverse events were reported in the pharmacokinetics trials and were considered probably related to Nabi-HB: elevated alkaline phosphatase 2 (4percent), ecchymosis 1 (2percent), joint stiffness 1 (2percent), elevated AST 1 (2percent), decreased WBC 1 (2percent), and elevated creatinine 1 (2percent). All adverse events were mild in intensity. There were no serious adverse events. No anaphylactic reactions with Nabi-HB have been reported.
