Efavirmg Tablet reduces the chances of getting HIV-related complications and improves your lifespan. It can be taken empty stomach or with food and is prescribed in combination with other HIV medicines. Taking all these medicines regularly at the right times greatly increases their effectiveness and reduces the chances of HIV becoming resistant to them. It is important to keep taking them regularly until your doctor tells you it is safe to stop.
Common side effects of this medicine include headache, nausea, vomiting, stomach pain, fatigue, diarrhea, and rash. These are usually not serious but tell your doctor if they bother you or do not go away. Consult your doctor urgently if you experience a skin reaction or liver damage.
Before taking it, tell your doctor if you have any skin, liver, or kidney problems. While using it, you may need regular blood tests to check your blood cell counts and liver function. Avoid drinking alcohol as it may increase your risk of liver damage. Pregnant or breastfeeding mothers should consult their doctor before using this medicine. Do not have unprotected sex or share personal items like razors or toothbrushes, if you are HIV positive. Talk to your doctor about safe ways like condoms to prevent HIV transmission during sex.

In HIV infection
It is not a cure for HIV or AIDS and should not be used to prevent HIV after accidental exposure to a risk.

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.
