Lamivudine is a nucleoside analogue used in antiviral therapy for the following conditions:

- HIV infection: suppresses viral replication and helps maintain immune function. - Chronic hepatitis B: reduces viral load and slows disease progression. - Prevention of mother‑to‑child transmission of HIV: lowers the risk of vertical transmission when given to pregnant women.

Lamivudine may cause a range of adverse reactions. Most are mild and reversible, but serious events can occur.

Common Side Effects: - Nausea: mild to moderate stomach upset. - Headache: intermittent cranial discomfort. - Fatigue: reduced energy levels. - Diarrhea: loose stools. - Insomnia: difficulty falling or staying asleep. - Dizziness: sensation of light‑headedness.

Serious or Rare Side Effects: - Lactic acidosis: severe metabolic disturbance requiring immediate care. - Hepatotoxicity: significant liver enzyme elevation or failure. - Pancreatitis: inflammation of the pancreas with abdominal pain. - Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Hypersensitivity: rash, fever, or organ involvement. - Renal impairment: worsening kidney function.

Before initiating lamivudine therapy, clinicians should consider several safety measures.

- Renal function: assess creatinine clearance and adjust dose if needed. - Hepatic status: monitor liver enzymes, especially in hepatitis B patients. - Pregnancy: evaluate risks versus benefits; data are limited. - Concomitant medications: review for potential interactions that may affect lamivudine levels. - Storage: Store at ambient temperature: keep in the original container, protect from moisture and direct sunlight.

Lamivudine can interact with other medicines, altering its efficacy or safety.

Major Interactions (Avoid): - Didanosine: increased risk of pancreatitis. - Tenofovir: potential additive renal toxicity. - Zidovudine: heightened bone marrow suppression.

Moderate Interactions (Monitor Closely): - Rifampicin: may reduce lamivudine plasma concentrations. - Proton pump inhibitors: possible effect on absorption, monitor clinical response.
