In multiple-dose clinical trials involving more than 3000 patients, 3 patients discontinued therapy because of treatment-related liver enzyme abnormalities and 1 because of a renal function abnormality. Difficile, and surgical evaluation should be instituted as clinically indicated. Nonclinical Toxicology Carcinogenesis, Mutagenesis, Impairment of Fertility Long-term studies in animals have not been performed to evaluate carcinogenic potential. Although a dose adjustment of azithromycin is not recommended when administered in combination with nelfinavir, close monitoring for known adverse reactions of azithromycin, such as liver enzyme abnormalities and hearing impairment, is warranted. Appropriate antibacterial therapy and follow-up tests for these diseases should be initiated if infection is confirmed. Chronic therapy with 1200 mg weekly regimen The nature of adverse reactions seen with the 1200 mg weekly dosing regimen for the prevention of Mycobacterium avium infection in severely immunocompromised HIV-infected patients were similar to those seen with short-term dosing regimens. Direct parents and caregivers to contact their physician if vomiting or irritability with feeding occurs.
