Study Shows Pill Prevents H.I.V. Among Drug Addicts

Drug-injecting addicts who took a daily antiretroviral pill were half as likely to become infected with H.I.V. as those who did not, a major new study has found, providing the final piece of evidence that such treatments can prevent AIDS in every group at risk. Earlier clinical trials showed that the therapy can sharply reduce the risk of H.I.V. transmission from mother to child, and in gay and bisexual men and heterosexuals.

Once-a-day pill prevents HIV in drug users

Daily Pill Cuts HIV Risk in IV Drug Users

The researchers enrolled 2,413 volunteers — ages 20 through 60, HIV-negative, and reporting injecting drugs within the previous 12 months — from 17 drug-treatment clinics in Bangkok.

Study participants were randomly assigned on a one-to-one basis to either tenofovir or placebo and followed for an average of 4 years. They were offered condoms and methadone treatment and got monthly HIV testing, combined with risk-reduction and adherence counseling and blood safety tests every 3 months.
