Warnings and Precautions
Hypersensitivity Reactions
Isolated cases of serious hypersensitivity (anaphylaxis and anaphylactoid) reactions (including shock) have been reported in patients receiving Mycamine. If these reactions occur, Mycamine infusion should be discontinued and appropriate treatment administered.
Hematological Effects
Acute intravascular hemolysis and hemoglobinuria was seen in a healthy volunteer during infusion of Mycamine (200 mg) and oral prednisolone (20 mg). This reaction was transient, and the subject did not develop significant anemia. Isolated cases of significant hemolysis and hemolytic anemia have also been reported in patients treated with Mycamine. Patients who develop clinical or laboratory evidence of hemolysis or hemolytic anemia during Mycamine therapy should be monitored closely for evidence of worsening of these conditions and evaluated for the risk/benefit of continuing Mycamine therapy.
Hepatic Effects
Laboratory abnormalities in liver function tests have been seen in healthy volunteers and patients treated with Mycamine. In some patients with serious underlying conditions who were receiving Mycamine along with multiple concomitant medications, clinical hepatic abnormalities have occurred, and isolated cases of significant hepatic impairment, hepatitis, and hepatic failure have been reported. Patients who develop abnormal liver function tests during Mycamine therapy should be monitored for evidence of worsening hepatic function and evaluated for the risk/benefit of continuing Mycamine therapy.
Renal Effects
Elevations in BUN and creatinine, and isolated cases of significant renal impairment or acute renal failure have been reported in patients who received Mycamine. In fluconazole-controlled trials, the incidence of drug-related renal adverse reactions was 0.4% for Mycamine treated patients and 0.5% for fluconazole treated patients. Patients who develop abnormal renal function tests during Mycamine therapy should be monitored for evidence of worsening renal function.[1]
