More Good News About HIV Prevention Drug Truvada

There is more good news about HIV treatment pills used to prevent infection in people at high risk of getting the AIDS virus: Follow-up from a landmark study that proved the drug works now shows that it does not encourage risky sex and is effective even if people skip some doses.

The research was discussed Tuesday at the International AIDS Conference in Melbourne, Australia, and was published by the British journal Lancet Infectious Diseases.

It involves 1,600 gay men and transgender women who took part in the original study showing that daily use of the drug Truvada (true-VAH'-duh) lowered the risk of getting HIV.
