IMPORTANT SAFETY INFORMATION
Rhophylac® is indicated to raise platelet counts in Rh0(D)-positive, non-splenectomized adult patients with chronic immune thrombocytopenic purpura (ITP). For the treatment of ITP, Rhophylac® must be administered IV.
Rhophylac® is contraindicated in individuals with known anaphylactic or severe systemic reaction to human immune globulin products.
Allergic or hypersensitivity reactions may occur with Rhophylac®; early signs of hypersensitivity include generalized urticaria, chest tightness, wheezing, hypotension, and anaphylaxis. Individuals with selective IgA deficiency can develop antibodies to IgA and may develop severe hypersensitivity and anaphylactic reactions. For these individuals, weigh the expected benefits of treatment against the potential risks.
Rhophylac® is derived from human plasma. As with all plasma-derived products, the risk of transmission of infectious agents, including viruses and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent, cannot be completely eliminated.
The most serious adverse reactions in patients receiving Rh0(D) immune globulin have been observed in the treatment of ITP. ITP patients being treated with Rhophylac® should be monitored for signs and symptoms of intravascular hemolysis, including back pain, shaking chills, fever, and hemoglobinuria. Potentially serious complications of intravascular hemolysis include clinically compromising anemia, acute renal insufficiency, and, very rarely, disseminated intravascular coagulation, and death.
The most common adverse reactions observed in the treatment of ITP are chills, pyrexia/increased body temperature, and headache. Mild extravascular hemolysis has also been observed. In patients with preexisting anemia, weigh the benefits of Rhophylac® against the potential risk of increasing the severity of the anemia.
