Perhaps he was thinking of nevirapine. According to the Washington Post:
Weeks before President Bush announced a plan to protect African babies from AIDS, top U.S. health officials were warned that research on the key drug was flawed and may have underreported thousands of severe reactions, including deaths, government documents show.
The 2002 warnings about the drug, nevirapine, were serious enough to suspend testing for more than a year, let Uganda's government know of the dangers and prompt the drug's maker to pull its request for permission to use the medicine to protect newborns in the United States.
Of course, I don't know that's what he was thinking of.
There are more than a dozen agents in 4 major classes that are used to treat HIV...all have side effects like other drugs, some worse then others. This guy is just misinformed.
