Warnings
All patients with HIV-1 should be tested for presence of chronic Hepatitis B virus (HBV) before initiating antiretroviral therapy; safety and efficacy of emtricitabine not established in patients coinfected with HBV and HIV-1; patients infected with HBV and treated with emtricitabine, the exacerbations of hepatitis B were associated with liver decompensation and liver failure; hepatic function should be monitored closely with both clinical and laboratory follow-up for at least several months in patients who are coinfected with HIV-1 and HBV and discontinue therapy; if appropriate, initiation of anti-Hepatitis B therapy may be warranted
Lactic acidosis and severe hepatomegaly with steatosis, including fatal cases, reported with use of nucleoside analogs, either alone or in combination with other antiretrovirals; suspend therapy in any patient who develops clinical or laboratory findings suggestive of lactic acidosis or pronounced hepatotoxicity (which may include hepatomegaly and steatosis even in the absence of marked transaminase elevations)
Should not be coadministered with combination antiretroviral agents containing emtricitabine or lamivudine
Dose reduction recommended in patients with impaired renal function
Risk of immune reconstitution syndrome if used in combination with other antiretroviral drugs; autoimmune disorders (such as Graves’ disease, polymyositis, and Guillain-Barré syndrome) reported to occur in the setting of immune reconstitution; however, time to onset is more variable, and can occur many months after initiation of treatment
