What is Efavirenz?

Efavirenz is used along with other HIV medications to help control HIV infection. This medication helps to reduce the amount of HIV in your body, which allows your immune system to work better. This also decreases your chances of getting HIV-related complications such as cancer, pneumonia, and other infections. This medication belongs to a class of drugs known as non-nucleoside reverse transcriptase inhibitors (NNRTIs). This medication is not a cure for HIV.

Take this oral capsule by mouth on an empty stomach, without food, usually once daily at bedtime. Taking Efavirenz with food increased the blood level of this medication, which may increase your risk of certain side effects. Swallow this medication whole with water. Do not eat any food for two hours after using this medication. For babies who are unable to eat solid food, the contents may be mixed in two teaspoons of infant formula and drawn up into an oral syringe to be given to the baby.

Your doctor will recommend an appropriate dose for you based on an assessment of your current medical condition, other drugs you are currently taking, and your response to treatment. Use this medication exactly as prescribed by your doctor. Do not increase your dose or use this drug more often than prescribed. Skipping or changing your dose without approval from your doctor may cause the amount of virus in your body to increase, making the infection more difficult to treat.

What are the side effects of Efavirenz?

Common side effects include dizziness, trouble sleeping, drowsiness, unusual dreams, and trouble concentrating. These side effects are usually temporary and go away as your body adjusts to treatment. Avoid using alcohol and street drugs while taking Efavirenz. They may worsen these side effects.

You may experience changes in body fat while you are taking this medication, such as increased fat in the stomach areas and upper back, and decreased fat in the arms and legs. The cause and long-term effects of these changes are not currently known. Talk to your doctor about the possible use of exercise to reduce this effect.
