What is Truvada?
Truvada contains a combination of emtricitabine and tenofovir. Emtricitabine and tenofovir are antiviral medicines that prevent HIV (human immunodeficiency virus) cells from multiplying in your body.
Truvada is used to treat HIV, the virus that can cause acquired immunodeficiency syndrome (AIDS). This medicine is not a cure for HIV or AIDS, but it can be used to treat HIV in adults and children who are at least 12 years old and weigh at least 17 kilograms (37 pounds).
Truvada may be used together with safer-sex practices to reduce the risk of becoming infected with HIV. You must be HIV-negative and an adult or an adolescent weighing at least 35 kg to use Truvada for this purpose. It may not provide protection from disease in every person.
Do not take Truvada if you also take other medicines that contain emtricitabine, tenofovir, lamivudine, or adefovir.
Truvada is sometimes used to reduce the risk of becoming infected with HIV. You must be HIV-negative and an adult to use the medicine for this purpose.
Truvada may cause a serious condition called lactic acidosis. Get emergency medical help if you have even mild symptoms such as: muscle pain or weakness, numb or cold feeling in your arms and legs, trouble breathing, stomach pain, nausea with vomiting, fast or uneven heart rate, dizziness, or feeling very weak or tired.
If you have hepatitis B you may develop liver symptoms after you stop taking this medicine, even months after stopping.
