The most common side effects reported with this drug have included headache, nausea, malaise, fatigue, nasal signs and symptoms, respiratory tract infections, throat and tonsil discomfort, abdominal discomfort and pain, vomiting, diarrhea, and cough. During clinical studies in HIV-1-infected patients, this drug was used with zidovudine (with or without other antiretroviral agents). Patients with hepatitis B virus (HBV) infection received lamivudine (the active ingredient contained in Epivir-HBV) monotherapy.[Ref]
