Lamivudine
About Lamivudine
Lamivudine is an antiviral medication used to treat human immunodeficiency virus (HIV-1) infection and chronic hepatitis B virus (HBV) infection. It works by keeping the viral replication process under control to support your immune system and protect your organs. This oral prescription medicine is available as either a tablet or an oral solution.
For the best results, you must take Lamivudine consistently every day at the same scheduled times as directed by your doctor. You can take Lamivudine with or without food, but keeping a regular schedule is key to preventing the virus from multiplying. Incorporating a nutrient-dense, liver-friendly diet and staying well-hydrated can also support your body’s response to the treatment.
While taking Lamivudine, you may experience mild side effects like headaches, nausea, or mild fatigue. However, you should contact your healthcare provider immediately if you experience signs of more serious issues, such as severe stomach pain, unusual muscle pain, or signs of liver damage like yellowing of your skin or eyes.
Before starting this treatment, tell your doctor if you have kidney problems, liver disease, or a history of pancreas inflammation. Do not take this if you have had a severe allergic reaction to this medication in the past.
Be sure to discuss all other medications you take, as certain antibiotics or other antiviral drugs can interact with Lamivudine and affect how it works. Additionally, you should consult your doctor before starting Lamivudine if you are pregnant, breastfeeding, or an older adult, to ensure your dosage is safe and appropriate.

View AllDrug Warnings
- Do not stop treatment abruptly: Never stop taking Lamivudine without consulting your doctor, as stopping treatment suddenly may cause a severe flare-up of hepatitis B and lead to serious liver complications.
- Take every dose as prescribed: Missing doses may allow HIV or hepatitis B viruses to become resistant to treatment, making future therapy less effective. Follow your treatment schedule carefully.
- Ensure appropriate testing before treatment: Testing for both HIV and hepatitis B may be required before starting Lamivudine, as treating one infection without properly managing the other can increase the risk of drug resistance.
- Attend regular monitoring appointments: Keep all scheduled follow-up visits and blood tests so your doctor can monitor your liver function, kidney function, and overall response to treatment.
- Inform healthcare providers before procedures: Tell your dentist, surgeon, or other healthcare professionals that you are taking Lamivudine before undergoing any medical or dental procedure.
- Be aware of immune system reactions: Some people starting HIV treatment may develop immune reconstitution inflammatory syndrome (IRIS), in which the recovering immune system reacts to previously hidden infections. Contact your healthcare provider if you develop new or worsening symptoms after starting treatment.
Drug Interactions
- Antiviral medicines (e.g., emtricitabine, zalcitabine, ribavirin): Taking these medicines alongside Lamivudine may affect how the treatment works or increase the risk of side effects. Your doctor may recommend additional monitoring or treatment adjustments.
- Antibiotics containing trimethoprim (e.g., trimethoprim): These medicines may increase the amount of Lamivudine in your body, potentially raising the risk of side effects.

Disease/Condition Glossary
Human immunodeficiency syndrome (HIV): It is a virus that suppresses the immune system and causes acquired immunodeficiency syndrome (AIDS) over time. The suppression of immunity leads to the development of opportunistic infections. It is a life-long condition, and there is no permanent cure. The treatment (antiretroviral therapy) is given to suppress the infection.
Chronic Hepatitis B: A severe and long-term liver infection caused by the hepatitis B virus (HBV). It spreads by contact with infected body fluids. The symptoms of this condition are abdominal pain, dark urine, and yellowing of the eyes.
