Store Lamivudine oral solution at room temperature, between 68°F and 77°F (20°C and 25°C). Protect it from light and excessive heat. Discard any unused solution after its expiration date, clearly printed on the label.
Never flush unused medications down the toilet or pour them into a drain. This practice contaminates water systems. Instead, follow your local regulations for proper medication disposal. Many pharmacies offer take-back programs; check with your pharmacist for details. If a take-back program is unavailable, securely wrap the solution in a sealed bag and dispose of it in your household trash.
Always keep Lamivudine oral solution out of reach of children and pets. If accidental ingestion occurs, seek immediate medical advice. Consult a doctor or pharmacist for further clarification on storage and disposal guidelines specific to your location.
