morning-after pill + PEP?

Aug 25, 2006

dr. bob! you are a wonderful human being.

here's a quick q: now that the morning-after pill is available over the counter, if me and a guy have, let's say, a little bit more fun than we should without protection, is it OK for me to take the morning-after pill at the same time i'm taking post-exposure prophylaxis drugs for hiv? or will one somehow cancel out the other or cause really bad side effects?

thanks so much, cf

Response from Dr. Frascino

Hello cf,

There is always the possibility of drug-drug interactions. Since I do not know what medications are in your hypothetical PEP regimen, I can't comment specifically. Your HIV specialist or the physician who prescribes the PEP should warn you about all potential drug interactions. You can also check on They have a feature that allows you to enter a particular combination of drugs and determine any specific drug-drug interactions. Your concerns about the morning-after pill and PEP cancelling each other out are unfounded.

Stay safe to stay well.

Dr. Bob
