Epivir (Lamivudine) Information

The active ingredient in Epivir is:

• Lamivudine: 150 mg or 300 mg per tablet

Other inactive ingredients may include:

• Microcrystalline cellulose
• Magnesium stearate
• Pre-gelatinized starch
• Croscarmellose sodium

Common side effects include:

• Headache
• Fatigue
• Nausea
• Dizziness
• Insomnia

Serious side effects requiring immediate medical attention:

• Lactic acidosis (symptoms include deep or rapid breathing, weakness, and muscle pain)
• Severe liver problems (jaundice, dark urine, abdominal pain)
• Pancreatitis (inflammation of the pancreas, which may cause abdominal pain, nausea, and vomiting)
• Severe allergic reactions (rash, swelling, difficulty breathing)

Epivir is usually taken once or twice daily with or without food. The dosage will depend on your specific medical condition and your doctor’s recommendations.

Important considerations:

• Take the medication exactly as prescribed by your healthcare provider.
• Do not stop taking Epivir without consulting your doctor, as this may lead to viral resistance.
• It is important to follow your doctor’s instructions about other HIV medications or treatment for hepatitis B.

Epivir may interact with other medications, so always inform your doctor about any other drugs you are taking, including over-the-counter medications, supplements, and herbal products.

Common interactions include:

• HIV medications: Epivir is often used in combination with other antiretroviral medications. Your doctor will recommend a suitable regimen.
• Hepatitis B treatments: If you have both HIV and hepatitis B, your doctor may prescribe a combination therapy that includes Epivir.
• Certain antibiotics or antifungals: Some may increase the levels of Epivir in the blood, increasing the risk of side effects.

Epivir begins working immediately, but its full effect may take several weeks or months. For HIV patients, the full therapeutic effect is usually achieved when combined with other HIV medications. For chronic hepatitis B, Epivir helps reduce viral replication over time, leading to improved liver function.

If you experience symptoms of lactic acidosis (deep, rapid breathing, muscle pain, and weakness) or severe liver issues (jaundice, dark urine), stop taking Epivir and seek immediate medical attention.

If you notice symptoms of pancreatitis or any unusual side effects, contact your doctor for further evaluation.
