Emtricitabine & Rilpivirine & Tenofovir Precautions
Serious side effects have been reported with this medication, including the following:
- A build-up of an acid in your blood (lactic acidosis). Lactic acidosis can happen in some people who take emtricitabine/rilpivirine/tenofovir or similar (nucleoside analogs) medicines. Lactic acidosis is a serious medical emergency that can lead to death.
- You may be more likely to get lactic acidosis or severe liver problems if you are female, very overweight (obese), or have been taking emtricitabine/rilpivirine/tenofovir or a similar medicine containing nucleoside analogs for a long time.
- Lactic acidosis can be hard to identify early, because the symptoms could seem like symptoms of other health problems. Call your healthcare provider right away if you get any of the following symptoms which could be signs of lactic acidosis:
- feeling very weak or tired
- have unusual (not normal) muscle pain
- have trouble breathing
- have stomach pain with nausea (feel sick to your stomach)
- feel cold, especially in your arms and legs
- feel dizzy or lightheaded
- have a fast or irregular heartbeat
- New or worse kidney problems, including kidney failure, can happen in some people who take emtricitabine/rilpivirine/tenofovir. Your healthcare provider should do blood tests to check your kidneys before starting treatment with emtricitabine/rilpivirine/tenofovir. If you have had kidney problems in the past or need to take another medicine that can cause kidney problems, your healthcare provider may need to do blood tests to check your kidneys during your treatment with emtricitabine/rilpivirine/tenofovir.
- Depression or mood changes. Tell your healthcare provider right away if you have any of the following symptoms:
- feeling sad or hopeless
- feeling anxious or restless
- have thoughts of hurting yourself (suicide) or have tried to hurt yourself
- Change in liver enzymes. People with a history of hepatitis B or C virus infection or who have certain liver enzyme changes may have an increased risk of developing new or worsening liver problems during treatment with emtricitabine/rilpivirine/tenofovir. Liver problems can also happen during treatment with emtricitabine/rilpivirine/tenofovir in people without a history of liver disease. Your healthcare provider may need to do tests to check your liver enzymes before and during treatment with emtricitabine/rilpivirine/tenofovir.
- Bone problems can happen in some people who take emtricitabine/rilpivirine/tenofovir. Bone problems include bone pain, softening or thinning (which may lead to fractures). Your healthcare provider may need to do additional tests to check your bones.
- Changes in body fat can happen in people taking HIV medicine. These changes may include increased amount of fat in the upper back and neck ("buffalo hump"), breast, and around the main part of your body (trunk). Loss of fat from the legs, arms and face may also happen. The cause and long term health effect of these conditions are not known.
- Changes in your immune system (Immune Reconstitution Syndrome) can happen when you start taking HIV medicines. Your immune system may get stronger and begin to fight infections that have been hidden in your body for a long time. Tell your healthcare provider if you start having new symptoms after starting your HIV medicine.
