Introduction to Heptavir 100mg Tablet

Heptavir 100mg tablet is an antiretroviral with an active ingredient called Lamivudine which belongs to the family called nucleoside analog reverse transcriptase inhibitors (NRTIs). It is used to treat HIV infection and chronic hepatitis B virus infection. HIV is a Human immunodeficiency virus that attacks and destroys the cells in the immune system; the body's ability to fight against infections decreases and leads to death if untreated properly. This medicine does not completely cure the infection; it reduces the amount of virus in your body and increases the CD4 cell count in your blood. These cells are important in helping your body to fight infection. Inform your physician if you have any liver disorders, including hepatitis B or C, kidney problems, or if you are overweight (especially if you are a woman) before taking this tablet. 

Inform your physician if you or your children have these conditions. Your doctor might take extra checkups, including blood tests, while under this treatment; Kidney patients might suggest dose adjustment. Do not take  Heptavir 100mg tablet if you are allergic to Lamivudine and its other ingredients. Inform your physician if you are pregnant or planning to get pregnant or breastfeeding. Discuss more fertility concerns with your doctor. Do not share personal objects such as toothbrushes or razors with anyone. Do not breastfeed. Consult your doctor about safe sex practices.
