Before starting Efavirenz/Emtricitabine/Tenofovir, discuss your complete medical history with your healthcare provider, especially if you have liver disease, kidney disease, osteoporosis, mental health conditions, or other significant health concerns.

- Unusual muscle pain or weakness

Liver Problems
This medication may cause serious liver problems, including liver damage or, in rare cases, liver failure.
The risk may be higher in people who:

Tell your healthcare provider immediately if you experience changes in mood, worsening depression, or thoughts of self-harm.
Kidney Problems
Tenofovir may affect kidney function, particularly in people with existing kidney disease or other risk factors.
Your healthcare provider may monitor your kidney function with blood and urine tests before and during treatment.
Bone Loss and Fracture Risk
Long-term use of tenofovir has been associated with:
- Reduced bone mineral density
- Osteoporosis
- An increased risk of bone fractures
The risk may be higher in people who already have osteoporosis or other risk factors for bone loss. Your healthcare provider may recommend monitoring bone health during treatment.
Immune Reconstitution Syndrome
As HIV treatment begins to strengthen the immune system, the body may start responding to previously hidden infections. This condition is known as immune reconstitution syndrome or immune reconstitution inflammatory syndrome (IRIS).
Symptoms can vary depending on the infection involved and should be reported to your healthcare provider promptly.

Efavirenz/Emtricitabine/Tenofovir can interact with many medications, including:

Tell your healthcare provider if you have:
- Heart disease
- High blood pressure
- High cholesterol
- Diabetes
- A history of smoking
Your healthcare provider can help monitor and manage any cardiovascular risk factors during treatment.
