One complication is that it makes "the antibiotics less effective in treating the infection it was intended to treat." So while booze might make you forget you have chlamydia, it might also reduce your chances of the medicine getting rid of it.
Or you could develop a superbug, which is as scary as it sounds
An even scarier complication is the fact that "exposure to sub-therapeutic levels of antibiotic can cause the development of resistant microbial strains over time." Why is that so scary? Enter: superbugs, which are bacteria unaffected by antibiotics. Superbugs are not a good look. If you never want to sleep again, read up on the havoc they can cause.
Oh, and you could die
Dr. Blohm says "it's pretty unlikely" you kick the bucket, but it's a possibility. "Drug interactions can be very dangerous and cause a host of problems," she said. "It isn't worth messing around with." She makes a very good point, adding, "Since antibiotics are nearly always prescribed for limited periods, it shouldn't be so hard to take a break from drinking."
