Interactions between your drugs
tenofovir boceprevir
Applies to: Genvoya (cobicistat / elvitegravir / emtricitabine / tenofovir alafenamide) and boceprevir
Boceprevir may increase the blood levels and effects of tenofovir. This can increase the risk of side effects including serious ones like kidney or liver damage and a condition known as lactic acidosis, which is a buildup of lactic acid in the blood. You should seek immediate medical attention if you develop symptoms of these conditions. Symptoms of kidney damage may include swelling, weight gain, shortness of breath, drowsiness, confusion, mood changes, increased thirst, loss of appetite, nausea, vomiting, pain in your lower back, and urinating more or less than usual or not at all. Symptoms of liver damage may include fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, dark colored urine, and/or yellowing of the skin or eyes. Symptoms of lactic acidosis may include fatigue, unusual muscle pain, difficulty breathing, stomach pain, nausea, vomiting, lightheadedness, dizziness, and a fast or irregular heartbeat. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
tenofovir cobicistat
Applies to: Genvoya (cobicistat / elvitegravir / emtricitabine / tenofovir alafenamide) and Genvoya (cobicistat / elvitegravir / emtricitabine / tenofovir alafenamide)
Using cobicistat together with tenofovir can increase the effects of tenofovir, which can cause new or worse kidney problems. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
emtricitabine cobicistat
Applies to: Genvoya (cobicistat / elvitegravir / emtricitabine / tenofovir alafenamide) and Genvoya (cobicistat / elvitegravir / emtricitabine / tenofovir alafenamide)
Cobicistat is a medication used to boost the effects of some medications that treat HIV infection. However, using cobicistat together with other HIV medications, such as emtricitabine, may alter the blood levels and effects of both medications. Using emtricitabine with cobicistat may reduce or increase blood levels of cobicistat. Reduced blood levels of cobicistat may make cobicistat less effective and may cause overall HIV treatment to be less effective. Cobicistat may increase blood levels of emtricitabine which may increase the risk of side effects. Talk to your doctor or pharmacist if you have any questions on how to use these medications properly. Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications. Contact your doctor if your condition changes or you experience increased side effects. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
