Uses of Duovir N Tablet

Benefits of Duovir N Tablet

HIV infection
Duovir N Tablet prevents the HIV virus from multiplying in your body. It helps control the infection and makes your immune system work better. This lowers your chances of getting complications such as new infections and improves your quality of life.

It is not a cure of HIV or AIDS and should not be used to prevent HIV after accidental exposure to a risk. It is important that you take this medicine as prescribed, following the dosage recommended by your doctor. Taking all doses in the right amount at the right times greatly increases the effectiveness of your combination of medicines and reduces the chances of your HIV infection becoming resistant to antiretroviral medicines. However, taking this medicine will not prevent you from passing HIV to other people.

How to use Duovir N Tablet

Take this medicine in the dose and duration as advised by your doctor. Swallow it as a whole. Do not chew, crush or break it. Duovir N Tablet may be taken with or without food.

How Duovir N Tablet works

Duovir N Tablet is a combination of three medicines: lamivudine, zidovudine, and nevirapine that work together to fight HIV by preventing the virus from multiplying in the body. Lamivudine and zidovudine belong to a class of medicines called nucleoside reverse transcriptase inhibitors (NRTIs). They work by blocking an enzyme called reverse transcriptase, which HIV needs to make more copies of itself. This helps slow down the spread of the virus. Nevirapine, on the other hand, is a non-nucleoside reverse transcriptase inhibitor (NNRTI). It attaches to the same enzyme but differently, making it even harder for HIV to multiply. By working together, these three medicines help protect the immune system and lower the risk of complications.
