What is Efavir?
Efavir containing the active ingredient efavirenz belongs to a class of medications called non-nucleoside reverse transcriptase inhibitors (NNRTIs). The medication works by decreasing the amount of HIV in the body and preventing the cells from multiplying to allow the immune system to work better. It must be used along with other medications to decrease the chance of developing acquired immunodeficiency syndrome (AIDS) and HIV related illnesses such as serious infections or cancer.
How is Efavir used?
Efavir is usually taken orally once per day at bedtime or as directed by a doctor. The medication should always be taken on an empty stomach along with plenty of water. Contact a doctor for the correct dosage as it will depend on the patientís condition and their response to the therapy. It is recommended to avoid consuming grapefruits or grapefruit juice as it may increase the amount of the drug in the bloodstream, making side effects more likely.
Patients using Efavir may encounter unwanted side effects such as:
- Difficulty concentrating
- Upset stomach
Contact a doctor immediately should side effects persist or encounter more severe side effects such as:
- Abnormal dreams
- Signs of new infections
- Loss of appetite and unexplained weight loss
- Lack of energy
- Mental or mood changes
- Irregular heartbeat
- Difficulty breathing or swallowing
The medication can be used to treat HIV but cannot be used to cure HIV or decrease the risk of transmitting the HIV virus to other people.
Immediately proceed to your nearest emergency department if you suffer an allergic reaction. Symptoms usually associated with such a reaction include difficulty breathing or swallowing, chest tightness, swelling, skin rashes, and hives.
