Sterman prescribes the drug off-label for about a dozen patients at high risk for developing AIDS. The pill, already used to treat people with HIV, also helps prevent the virus from infecting healthy people. The Food and Drug Administration is expected to decide by June 15 whether the pill’s maker Gilead Sciences should be allowed to formally market the drug for preventive use. (AP Photo/Jeff Chiu)
