Efavirenz is a medicine used to manage viral infections. Stopping the virus from making copies of itself, Efavirenz keeps viral numbers low within the bloodstream.
Efavirenz is the active compound in several HIV-treatment tablets, such as those simply labeled Efavirenz. It belongs to a class called non-nucleoside reverse transcriptase inhibitors, which work by stopping a key step the virus needs to copy itself.
Efavirenz is one part of combination therapy that many people with HIV use to lower the amount of virus in the blood. By keeping the viral load down, it can help protect the immune system and reduce the risk of illness.
Efavirenz-containing medicines are used to treat HIV infection in adults and children. They are taken together with other HIV drugs to help lower the amount of virus in your bloodstream, support your immune health, and reduce the chance of HIV-related complications.
After you swallow the tablet, efavirenz is absorbed and travels to cells where HIV tries to make copies of its genetic material. It blocks an enzyme called reverse transcriptase, which the virus needs to turn its RNA into DNA. By stopping this step, efavirenz slows the virus's ability to spread, giving your immune system a better chance to stay strong.
Pregnant or breastfeeding people should use efavirenz only if the benefits outweigh the risks, and those with liver problems or a history of mental health issues may need extra monitoring. Alcohol, certain antacids, and some seizure medications can affect how efavirenz works, so check the label of any other product you take.
People with a history of mental health disorders, existing liver disease, or who are pregnant may experience these side effects more often. Older adults and those taking many other medicines can also be more sensitive to efavirenz's effects.
Keep your tablets in the original container, tightly closed, and store them at room temperature away from excess heat, light, and moisture. The medication may be taken for a long period as part of ongoing HIV care, but each product can differ in strength and directions.
For detailed usage, dosing, and administration, refer to the specific medication's clinical information.
