Epivir (Lamivudine)

Indications

Epivir (lamivudine) is an antiviral medication used to treat HIV-1 infection in combination with other antiretroviral drugs. Epivir is also used to treat chronic hepatitis B virus infection in adults and children. It belongs to a class of medications called nucleoside reverse transcriptase inhibitors (NRTIs), which work by reducing the amount of HIV or hepatitis B virus in the body, slowing down the progression of the disease and improving the immune system.

Epivir should always be used in combination with other antiviral medications as prescribed by a healthcare provider. It can be used with other HIV medications to help control HIV infection. It helps to decrease the amount of HIV in your body so your immune system can work better. This lowers your chance of getting HIV complications (such as new infections, cancer) and improves your quality of life.

Uses and Dosage

Epivir (Lamivudine) comes in tablet form and is taken orally, with or without food, usually once or twice daily. To use Epivir tablet, take it by mouth with or without food as recommended by your doctor, typically once or twice daily. Patients who cannot swallow tablets should use the oral solution, or alternatively they may crush the tablets and add them to a small amount of food or drink immediately before swallowing it.

Be sure to follow the dosage and frequency instructions carefully and do not change your dose without your doctor's direction. Taking Epivir tablet inconsistently or stopping it abruptly can make the infection more challenging to treat or cause adverse side effects. Also, take it at the same time(s) each day to achieve the most beneficial outcome.

The recommended dose of Epivir for adults and children weighing at least 25 kg is 300 mg a day. This can be taken either as a single daily dose or divided into 150 mg twice a day. In children weighing less than 25 kg the recommended dose depends on their weight.
