General Info

Truvada is an HIV medication. It is in a category of HIV medicines called nucleoside reverse transcriptase inhibitors. Truvada was approved by the U.S. Food and Drug Administration for the treatment of HIV in August 2004. Truvada was approved for use as PrEP to prevent HIV among those at high risk in July 2012. 

Truvada is a coformulation of two drugs: Viread (tenofovir DF) and Emtriva (emtricitabine). Both of these drugs can still be purchased individually for use in combination with other HIV drugs

As HIV treatment, Truvada must be used in combination with other HIV drugs.

As PrEP, Truvada should be used in combination with risk-reduction counseling, correct and consistent condom use, regular HIV testing and screening for and treatment of other sexually transmitted infections.

Side Effects

Common side effects among people using Truvada as a component of a treatment regimen include: diarrhea, nausea, tiredness, headache, dizziness, depression, problems sleeping, abnormal dreams, and rash.

Common side effects among people using Truvada as PrEP include: headache, stomach-area (abdomen) pain, and decreased weight.

Truvada may lead to new or worsening kidney problems, including kidney failure. Your healthcare provider may order creatinine clearance (CrCl) tests to check your kidneys before and during treatment with Truvada. If you develop kidney problems, your healthcare provider may adjust your medication doses or switch Truvada for other HIV medications.

Truvada may lead to bone problems, including bone pain or bones getting soft or thin, which may lead to fractures. Your healthcare provider may do tests to check your bones.

If you also have hepatitis B virus (HBV) and take Truvada, your hepatitis may become worse if you stop taking Truvada. Do not stop taking Truvada without first talking to your healthcare provider.

Drug Interactions

Tenofovir disoproxil fumarate decreases Reyataz (atazanavir) concentrations in the blood; atazanavir increases tenofovir disoproxil fumarate concentrations in the blood. Atazanavir should be combined with ritonavir (Norvir) if tenofovir disoproxil fumarate is also being used. Combining Truvada with atazanavir and Norvir (ritonavir), Prezista (darunavir) and ritonavir, or Kaletra (lopinavir/ritonavir) increases tenofovir concentrations in the blood; may increase risk or severity of tenofovir side effects.

Truvada should not be combined with any HIV medications that contain any of the active ingredients in Truvada. These include: Atripla, Complera, Emtriva, Genvoya, Stribild, or Viread. Combining Truvada with HIV medications containing active ingredients similar to those in Truvada should also be avoided. These include: Combivir, Epivir, and Trizivir.

Other drug interactions are possible. Consult the Truvada package insert for more details: http://www.gilead.com/~/media/Files/pdfs/medicines/hiv/truvada/truvada_pi.PDF
