(July 22, 2014) Researchers say use of the HIV treatment pills used to prevent infection in people at high risk of getting the AIDS virus does not encourage risky sex and is effective even if people skip some doses.
The results are from longer follow-ups on more than 1,600 gay men in a landmark study a few years ago testing daily doses of the pill Truvada.
About three-quarters of the participants kept taking the pills for another 17 months, and none who used them four or more days a week got HIV, and even taking the pills less often helped, although not as much.
The work was discussed Tuesday at the International AIDS Conference in Melbourne, Australia.
