A new study indicates that daily HIV medication to HIV negative gay men who run a high risk of getting infected is highly effective in preventing new infections.
The study by Sheena McCormack of the Medical Research Council (MRC) Clinical Trials Unit at University College London, UK, adds that there was no evidence of increase in other sexually transmitted infections, as well.
The daily medication did not cause any serious adverse drug reactions.
Researchers said that the study strongly support s the addition of pre-exposure prophylaxis (PrEP) to the standard of prevention for men who have sex with men at risk of HIV infection.
"Our results refute concerns that the effectiveness of PrEP would be compromised when used in clinical practice, and the reduction in HIV incidence exceeded that reported from any placebo-controlled trial. The incidence of HIV infection among men not on PrEP was high (nine cases per 100 person-years), implying that the offer of PrEP is likely to attract individuals who are most likely to benefit from it," researchers said.
