You can avoid problems by learning about potential interactions with your HIV meds

Your pharmacist can be helpful too. The list below shows how heartburn and GERD medications can interact with drugs to treat HIV. Tell your doctor right away if any of the drugs listed are part of your regimen.
Antacids & HIV Drugs Alka Seltzer, Maalox, Mylanta, Tums, Rolaids, etc.

Rescriptor (delavirdine)—should be taken at least one hour apart
Reyataz (atazanavir)—should be taken two hours before or one hour after antacids
