Efavirenz is a medication that belongs to a class of drugs known as non-nucleoside reverse transcriptase inhibitors (NNRTIs). It is commonly used in the treatment of HIV infection, either on its own or in combination with other antiretroviral medications. Efavirenz works by inhibiting the enzyme reverse transcriptase, which is essential for the replication of the HIV virus.

It is important to take Efavirenz exactly as prescribed by your healthcare provider, typically once daily on an empty stomach. This medication should not be taken with food, as it can affect its absorption and effectiveness. It is also important to avoid alcohol while taking Efavirenz, as it can increase the risk of side effects.

Common side effects of Efavirenz may include dizziness, drowsiness, trouble sleeping, and vivid dreams. These side effects usually improve over time as your body adjusts to the medication. However, if you experience severe or persistent side effects, it is important to contact your healthcare provider.

It is important to note that Efavirenz is not a cure for HIV infection, but rather helps to control the virus and improve the immune system. It is important to continue taking this medication as prescribed, even if you feel well. Stopping Efavirenz suddenly can lead to the virus becoming resistant to the medication and may result in a worsening of your condition.

If you have any questions or concerns about Efavirenz or its use in your treatment regimen, do not hesitate to speak with your healthcare provider. They can provide you with more information and guidance on how to best manage your HIV infection.
