The Efavir Tablets belong to the class of Antiretroviral drugs, which are used in treating HIV infection. These are manufactured by Cipla, and contain Efavirenz (600 mg) as its active component.



Efavir Tablets are used together with other antiretroviral medications to treat HIV infections. 

It can also be used to prevent HIV after needlestick injuries or other potential exposure to HIV.


How do the Efavir Tablets work?

Efavirenz, the main component of Efavir Tablets, is a non-nucleoside reverse transcriptase inhibitor. Reverse transcriptase is a vital enzyme that HIV needs to multiply. By inhibiting this enzyme, the amount of HIV in the body decreased.

This medication does not cure HIV. When taken properly in a combination with other antiretroviral medicines, it can help reduce HIV to undetectable levels. When HIV is undetectable in the body, you cannot pass it on to another person, even through unprotected sex.
