Warning and Precautions

  • Exercise caution if administering atazanavir to those with hepatic impairment.

In these patients, perform testing of the hepatic laboratory before starting and during treatment. 
  • Use Ritonavir with caution in those with underlying structural heart disease, cardiomyopathies, ischemic heart disease, and preexisting conduction system abnormalities, as these patients may be at greater risk for cardiac conduction abnormalities.
  • Increased hepatic transaminase exceeding 5 times the upper limit of normal, clinical hepatitis, and jaundice may occur in those receiving ritonavir alone or together with other antiretroviral medicines. Monitor increased AST/ALT, especially during the initial three months of atazanavir ritonavir therapy.
  • Allergic reactions including bronchospasm, mild skin eruptions, urticaria, and angioedema may occur with ritonavir. Anaphylaxis, Stevens-Johnson syndrome, and toxic epidermal necrolysis (TEN) may also occur. Stop treatment in case serious reactions develop. 
  • Cases of nephrolithiasis may occur in HIV-infected patients taking atazanavir treatment. In case signs and symptoms of nephrolithiasis or cholelithiasis occur, temporarily interrupt or stop atazanavir therapy. 
  • Ritonavir may be responsible for increased triglycerides, cholesterol, SGPT (ALT), SGOT (AST), CPK, GGT, and uric acid. Perform relevant laboratory testing prior to initiating treatment with ritonavir and at periodic intervals or if any clinical signs and symptoms occur during therapy.
