Question ID: 427660
I was perscribed Bactrim, an antibiotic usually used for ear
infections and such, to treat my acne. When I go back to college
though, I have every intention of drinking alcohol on the weekends (I
don't drink ridiculously dangerous amounts, but enough to have fun.)
I'm worried about the possible effects of drinking while on this
medication. Will it just decrease the antibiotic's ability to work, or
make me more succeptible to intoxication? Or is it an actually
dangerous combination?

It's actually a potentially dangerous combination, especially for
people with underlying cardiac issues.  If you're otherwise healthy,
it's probably not a serious medical threat, but it will likely make
you very sick.  Bactrim (well, one of its components) is a sulfa drug,
and has the effect of inhibiting one of the enzymes in alcohol
metabolism.  When you drink, your body quickly develops very high
levels of an intermediary (acetaldehyde) which makes you feel flushed,
can induce nausea and vomiting, high pulse, and widened pulse
pressures.
This article
http://pubs.niaaa.nih.gov/publications/arh23-1/40-54.pdf
gives a nice summary of the physiology of alcohol metabolism, if
you're interested, and table 2 lists meds that can cause similar
reactions. (These reactions are called disulfiram-like reactions
because they're similar to, you guessed it, disulfiram, a medicine
used to encourage alcoholics who are trying to stop drinking.  They
take the pill every day, and if they cheat and have a drink, they get
really sick)
I don't think the alcohol will decrease the ability of the antibiotic to work.

Good luck.
