Can flagyl and/or ciprofloxacin in combination with alcohol cause a higher breathalyzer reading and/or cause alcohol to remain in your system longer?

Why do you ask?: Your doctor must have told you not to drink while you're taking flagyl. It's quite dangerous. And while you're on "Cipro", both alcohol and caffeine are best avoided. They won't actually raise the level. If you failed a breathalyzer, you need both a good lawyer and an eagerness to make sure that nothing like this ever happens again. Best wishes.

Worse: You should not be taking alcohol while on such medication. Even without being on medication, alcohol is a poison that never did anybody any good, ever, stay away from it.
