Efavirenz is a medication used in the treatment of HIV (human immunodeficiency virus) infection. It belongs to a class of drugs known as non-nucleoside reverse transcriptase inhibitors (NNRTIs).

Efavirenz works by inhibiting the reverse transcriptase enzyme, which is essential for the replication of the HIV virus. By blocking this enzyme, efavirenz helps to reduce the viral load in the body and slow down the progression of HIV infection.

The medication is typically taken orally in the form of tablets. It is often prescribed as part of combination antiretroviral therapy (ART), which involves using multiple drugs to target different stages of the HIV life cycle. The specific combination and dosage of drugs are determined by the healthcare provider based on the individual’s HIV strain, treatment history, and other factors.

Common side effects of efavirenz may include dizziness, headache, nausea, and rash. More serious side effects, such as psychiatric symptoms or liver problems, can occur but are less common. Regular monitoring of liver function and viral load may be recommended during treatment.

Efavirenz should only be used under the guidance and prescription of a qualified healthcare professional experienced in the treatment of HIV infection. It may interact with other medications, so it is important to inform the healthcare provider about all medications being taken, including over-the-counter drugs and supplements.

In summary, efavirenz is a medication used in the treatment of HIV infection. It inhibits the reverse transcriptase enzyme to reduce the viral load and slow down the progression of HIV. Regular monitoring and adherence to healthcare provider instructions are important during efavirenz treatment.
