About Efavirenz+emtricitabine+tenofovir Disoproxil Fumarate
Efavirenz+emtricitabine+tenofovir Disoproxil Fumarate is a prescription tablet used to treat Human Immunodeficiency Virus type 1 (HIV-1) infection in adults and eligible children. It functions as a complete treatment regimen to control the virus and support the immune system. This medicine is not a cure for HIV-1 or AIDS, but it helps manage the condition long-term by keeping the viral load low.
For this medicine to work effectively, it must be taken consistently once a day, exactly as directed by your doctor. Taking it at bedtime on an empty stomach is highly recommended, as this timing helps minimise dizziness and sleep-related side effects. Adopting a balanced diet and avoiding high-fat meals around your dosing time can further support successful treatment results.
Some patients may experience mild side effects like trouble sleeping, headache, or mild dizziness when starting treatment. However, you must consult your doctor immediately if you experience serious symptoms such as signs of liver damage, deep depression, or a severe, painful skin rash.
Do not take this if you have a known severe allergy to any of its components or if you suffer from severe liver disease. Before starting this treatment, tell your doctor if you have a history of kidney disease, mental health disorders, or Hepatitis B infection. Your doctor may perform blood tests, including resistance testing, before starting treatment to ensure this medicine is suitable and likely to work effectively against your HIV infection.
Efavirenz+emtricitabine+tenofovir Disoproxil Fumarate can interact with several other prescription drugs, alcohol, and herbal supplements like St. John's Wort, which can reduce its effectiveness or increase the risk of harmful side effects. It is highly important for pregnant women, breastfeeding mothers, and older adults to consult their healthcare provider before using this medicine.

Patients Concern
Disease/Condition Glossary
HIV infection: HIV (human immunodeficiency virus) is a virus that attacks the immune system, making the individual susceptible to other conditions or illnesses. People with HIV experience flu-like symptoms such as fever, chills, rash, night sweats, muscle aches, tiredness, and sore throat. These symptoms usually last for days to several weeks. It spreads through body fluids such as semen, vaginal fluid, and blood. This condition can lead to AIDS (Acquired Immunodeficiency Syndrome). It is a life-long condition, and there is no definite cure. However, it can be controlled by treating it with antiretroviral agents.
