Adverse Reactions

The following adverse reactions are discussed in greater detail in other sections of the labeling:

  • Hematologic toxicity, including neutropenia and anemia [see Boxed Warning, Warnings and Precautions (5.1)].
  • Symptomatic myopathy [see Boxed Warning, Warnings and Precautions (5.2)].
  • Lactic acidosis and hepatomegaly with steatosis [see Boxed Warning, Warnings and Precautions (5.3)].
  • Acute exacerbations of hepatitis B [see Boxed Warning, Warnings and Precautions (5.4)].
  • Hepatic decompensation in patients co-infected with HIV-1 and hepatitis C [see Warnings and Precautions (5.6)].
  • Exacerbation of anemia in HIV-1/HCV co-infected patients receiving ribavirin and zidovudine [see Warnings and Precautions (5.6)].
  • Pancreatitis [see Warnings and Precautions (5.7)].

Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

Lamivudine Plus Zidovudine Administered As Separate Formulations: In 4 randomized, controlled trials of EPIVIR 300 mg per day plus RETROVIR 600 mg per day, the following selected adverse reactions and laboratory abnormalities were observed (see Tables 1 and 2).

Pancreatitis was observed in 9 of the 2,613 adult patients (0.3%) who received EPIVIR in controlled clinical trials [see Warnings and Precautions (5.7)].

Selected laboratory abnormalities observed during therapy are listed in Table 2.

Postmarketing Experience

In addition to adverse reactions reported from clinical trials, the following reactions have been identified during post-approval use of EPIVIR, RETROVIR, and/or COMBIVIR. Because they are reported voluntarily from a population of unknown size, estimates of frequency cannot be made. These events have been chosen for inclusion due to a combination of their seriousness, frequency of reporting, or potential causal connection to EPIVIR, RETROVIR, and/or COMBIVIR.
