Tenvir EM is a medication used to treat chronic hepatitis B and to prevent and treat HIV and AIDS.
For HIV 1 infection, tenofovir is indicated in combination with other antiretroviral agents for people 2 years of age and older. For chronic hepatitis B patients, tenofovir is indicated for patients 12 years of age and older.
It may be used for prevention of HIV and AIDS among those at high risk before exposure, and after a needlestick injury or other potential exposure.
Tenofovir can be used for HIV prevention in people who are at high risk for infection through sexual transmission or injecting drug use. A Cochrane review examined the use of tenofovir for prevention of HIV before exposure and found that both tenofovir alone and the tenofovir and emtricitabine combination decreased the risk of contracting HIV for high risk patients.
