Compare Truvada vs. Epivir

Head-to-head comparisons of medication uses, side effects, warnings, and more.

Key takeaways

Truvada (emtricitabine/tenofovir disoproxil fumarate) and Lamivudine (Epivir) are both antiretroviral medications used to treat HIV, but they have some key differences. Truvada is a combination of two drugs and is also used for HIV prevention (PrEP), while Lamivudine is a single medication that can treat both HIV and hepatitis B (HBV). Truvada is taken once daily, whereas Lamivudine can be taken once or twice daily depending on the condition being treated. Truvada is known to cause side effects like nausea, diarrhea, and dizziness, while Lamivudine commonly causes headache, nausea, and tiredness. Truvada requires regular blood tests to monitor kidney and liver health, and it can cause bone problems. Lamivudine also requires regular monitoring but has fewer interactions with other medications. Both medications can worsen hepatitis B if stopped suddenly, so it's important to follow your provider's instructions carefully.
