Health officials Wednesday issued guidelines for the use of a pill to prevent HIV infection among those at high risk of contracting the disease.
In its recommendations, the Centers for Disease Control and Prevention (PDF) told healthcare providers to consider the use of pre-exposure prophylaxis, or PrEP, an antiretroviral drug taken daily by intravenous drug users and men and women who are sexually active with multiple partners, who are known to be at higher risk for HIV infection.
