Frequently Asked Questions

What is Heptavir 100mg Tablet used for?

›

Heptavir 100mg Tablet is used in the treatment of chronic hepatitis B virus (HBV) infection. It contains Lamivudine 100mg, a nucleoside reverse transcriptase inhibitor (NRTI), which lowers the amount of hepatitis B virus in the body and helps reduce ongoing liver inflammation. It is prescribed as part of long-term hepatitis B management under a doctor’s supervision.

Is Heptavir 100mg Tablet for HIV or hepatitis B?

›

The 100mg strength of Heptavir is intended for chronic hepatitis B, not for HIV treatment. Lamivudine is used in both conditions, but HIV treatment requires a higher strength taken alongside other antiretroviral medicines. Taking the hepatitis B strength alone when HIV is also present can lead to HIV drug resistance, which is why doctors test for HIV before starting this medicine.

What is the difference between Heptavir 100 and Heptavir 150?

›

Both contain the same active ingredient, Lamivudine, but at different strengths for different conditions. Heptavir 100 is the hepatitis B strength. Heptavir 150 is used within combination antiretroviral therapy for HIV-1. The two are not interchangeable, and only your doctor can decide which strength is right for you.

What is the recommended dosage of Heptavir 100mg Tablet?

›

The usual adult dose is one tablet once daily, or exactly as prescribed by your doctor. It can be taken with or without food. Swallow the tablet whole with water and take it at the same time each day to keep drug levels steady. Never change the dose or stop treatment without medical advice.

Can Heptavir 100mg Tablet cure hepatitis B?

›

No. Heptavir 100mg Tablet does not cure hepatitis B. It controls the infection by reducing viral replication, which helps lower the viral load and slow the progression of liver damage. Treatment is usually long term, and your doctor will decide how long you need to continue based on your response and test results.

What happens if I stop taking Heptavir 100mg Tablet?

›

Stopping hepatitis B treatment suddenly can cause a severe flare-up of the infection, with a sharp rise in viral load and worsening liver inflammation. This can happen even if you feel completely well. Never stop, pause, or restart this medicine on your own. If treatment is ever stopped, your doctor will monitor your liver closely for several months afterwards.

What should I do if I miss a dose of Heptavir 100mg Tablet?

›

If you miss a dose, take it as soon as you remember. If it is close to the time of your next dose, skip the missed one and continue your regular schedule. Do not take a double dose to make up for the one you missed. Consistent daily dosing matters, because missed doses raise the risk of the virus becoming resistant.

Does Heptavir 100mg Tablet interact with other medicines?

›

Yes. Lamivudine can interact with certain medicines, including some medicines used for HIV, some antibiotics, and medicines that affect kidney function. Alcohol and medicines that strain the liver also need care. Tell your doctor about every medicine, supplement, or herbal product you take before starting treatment.

Is Heptavir 100mg Tablet safe for people with kidney or liver problems?

›

Lamivudine is cleared by the kidneys, so people with reduced kidney function may need a lower dose. Because this medicine is used to treat a liver infection, liver function is also monitored during treatment. Tell your doctor about any kidney or liver condition before starting, and attend all follow-up tests your doctor arranges.

Can hepatitis B become resistant to Heptavir 100mg Tablet?

›

Yes. With long-term lamivudine treatment, the hepatitis B virus can change in ways that make the medicine less effective. This is why doctors monitor viral load through regular blood tests. If resistance is detected, your doctor may adjust or change your treatment. Taking every dose on time reduces the chance of resistance developing.
