Efavirenz is a drug used to treat HIV infection. It belongs to a group called NNRTIs, which stop the virus from multiplying. People on Efavirenz usually take it with other HIV medicines as part of a combination therapy. The goal is to keep the virus at low levels, protect the immune system, and improve health.
The virus needs an enzyme called reverse transcriptase to turn its genetic material into a form that can infect cells. Efavirenz blocks this enzyme, so the virus can’t make new copies of itself. By cutting off the virus’s replication line, the drug helps the body’s defenses stay stronger. It doesn’t cure HIV, but it can keep the virus under control for years when taken correctly.
The usual adult dose is 600 mg once a day, taken on an empty stomach. That means you should swallow the tablet at least one hour before or two hours after eating. Some doctors start with a lower dose and increase it to avoid side effects. If you miss a dose, take it as soon as you remember—unless it’s almost time for the next dose, then just skip the missed one. Never double‑up; that can raise the risk of side effects.
Most people feel a bit dizzy or have a headache when they first start Efavirenz. Those symptoms often fade after a week or two. Other common effects include trouble sleeping, vivid dreams, and mild nausea. If you notice severe rash, fever, or mood changes such as depression or anxiety, call your doctor right away. Efavirenz can affect liver enzymes, so regular blood tests are important, especially if you have liver disease.
Alcohol can make side effects worse, and some medicines, like certain antidepressants or anti‑seizure drugs, can interact with Efavirenz. Always tell your doctor about every prescription, over‑the‑counter drug, and supplement you take. Women who are pregnant should discuss the risks, because Efavirenz may harm a developing baby.
Sticking to the schedule is the biggest factor for success. Setting a daily alarm or using a pill organizer helps a lot. If you travel across time zones, keep the same interval between doses—don’t reset the clock based on the new local time.
In summary, Efavirenz is a powerful tool against HIV when you follow the dosing rules, monitor side effects, and stay in touch with your healthcare team. Keeping the virus suppressed means a healthier life, fewer infections, and a lower chance of passing HIV to others.
