ATLANTA, June 13 (UPI) -- The medication tenofovir, or Viread, taken once a day may prevent HIV transmission among injection drug users, U.S. researchers say.
Dr. Michael Martin of the Centers for Disease Control and Prevention in Atlanta said a randomized, phase III trial of injection drugs users in Bangkok found daily tenofovir reduced the risk of human immunodeficiency virus by nearly half compared with a placebo, MedPage Today reported.
