Method of Usage



What is Lamivudine(Lamivir)?


Lamivudine is a prescription medicine that is used in treatment of HIV infection and chronic hepatitis B virus (HBV) infection.


It helps to prevent multiplication of viruses in human cells and stops viruses from producing new viruses. This further clears up infection.


Human immunodeficiency virus (HIV) is a sexually transmitted infection that leads to acquired immunodeficiency syndrome (AIDS) over time.


While chronic hepatitis B is a long-term viral infection that is caused by hepatitis B virus.


Dose of Lamivir 150mg and 300mg is used for treatment of human immunodeficiency virus (HIV) infection.


While a dose of Lamivir 100mg is effective in treating hepatitis B virus infection.


Lamivudine is available under brand names Epivir and Epivir HBV. Cipla Ltd. produces this medication.

  • HIV and hepatitis B treatment

How does Lamivudine work?


Lamivudine belongs to a class of medicines known as nucleoside reverse transcriptase inhibitors (NRTIs).


This medicine will not cure your HIV or HBV infection but help to slow down progression of these diseases by restricting ability of viruses to replicate.


To replicate and spread in your body, HIV and HBV require to use of an enzyme known as reverse transcriptase.


NRTIs like lamivudine stop this enzyme. This action prevents HIV and HBV from making copies and slows down spread of viruses.


If Lamivudine is used on its own to treat HIV then it might cause drug resistance.


It should be used in combination with almost two other antiretroviral medicines to control HIV.
