HepaGam B FDA Prescribing Information: Side Effects
Overall Adverse Reaction Profile
The most common expected adverse drug reactions for intravenous immune globulins like HepaGam B (hepatitis b immune globulin (human)) are chills, fever, headaches, vomiting, allergic reactions, nausea, arthralgia and moderate low back pain.7-8 In a clinical trial in liver transplant patients, 2 adverse drug reactions of tremor and hypotension were reported in 2 of 14 patients who received intravenous infusions of HepaGam B.8 In studies with healthy volunteers, only 1 adverse drug reaction of nausea was reported in the 70 adult subjects who received an intramuscular administration of HepaGam B (hepatitis b immune globulin (human)) .8
Although no anaphylactic reactions have been reported following HepaGam B (hepatitis b immune globulin (human)) administration, anaphylactic reactions have been reported following the administration of other immune globulin products on rare occasions [see WARNINGS AND PRECAUTIONS].
Adverse Reactions in Clinical Trials
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Hepatitis B-Related Liver Transplantation
In an ongoing clinical trial, only 2 adverse drug reactions occurred following the 313 (<1%) HepaGam B (hepatitis b immune globulin (human)) infusions in 14 liver transplant patients. A listing of all adverse events (including those assessed as unrelated to study drug) occurring in >10% of patients are summarized in Table 4 below. These adverse events were reported in an interim analysis from a one-year Phase 3 clinical trial examining HepaGam B (hepatitis b immune globulin (human)) for the prevention of hepatitis B recurrence following liver transplantation. This study utilized the recommended dosing regimen outlined in Table 1 [See DOSAGE AND ADMINISTRATION]. The 2 attributed adverse drug reactions of tremor and hypotension were reported in 2 patients. All reactions were associated with a single HepaGam B (hepatitis b immune globulin (human)) infusion during the first week post-transplant. All reactions resolved on the same day and did not recur with subsequent HepaGam B (hepatitis b immune globulin (human)) infusions.

Healthy Volunteer Studies
Seventy healthy male and female volunteers received a single dose of HepaGam B™ (Hepatitis B Immune Globulin Intravenous [Human]) intramuscularly in clinical trials.8 Seventeen (17) subjects reported 30 adverse events following administration of HepaGam B (hepatitis b immune globulin (human)) . The most frequently reported adverse events included 4 subjects (6%) who experienced headache. 7 subjects (10%) who had cold symptoms or flu and 2 subjects (3%) who experienced lightheadeness/ fainted. The majority of events were reported as mild and were not related to study drug. One adverse event, an episode of nausea, was considered to be drug related. There were no serious adverse events reported. A similar number of subjects in the comparator groups reported adverse events.
As of April 2007, there have been no postmarketing adverse events reported for HepaGam B (hepatitis b immune globulin (human)) administered i.m.
