Nucleoside analogue (reverse transcriptase inhibitor).
Warnings/Precautions:
Discontinue if pancreatitis (increased risk in pediatric patients) or lactic acidosis occurs. Suspend therapy if hepatotoxicity (eg, hepatomegaly, steatosis) occurs. Women, obesity, or prolonged nucleoside exposure: increased risk of toxicity (ie, lactic acidosis, steatosis). Hepatitis B (monitor for post-treatment exacerbation). Other liver disease risk factors. Diabetes (oral soln). Children with prior antiretroviral nucleoside exposure, history of pancreatitis or risk factors for pancreatitis. Pregnancy (Cat.C). Nursing mothers: not recommended.
Interactions:
Concomitant zalcitabine: not recommended. Avoid concomitant drugs that contain lamivudine or emtricitabine. Caution with drugs eliminated by active organic cationic secretion (eg, trimethoprim). Increased lamivudine absorption with TMP/SMX (clinical significance unknown). Triple therapy (once daily regimen) with abacavir + tenofovir or with didanosine + tenofovir: high rate of early viral non-response (see literature). Monitor for treatment-associated toxicities with interferon-alpha with or without ribavirin.
