How many days can i have sex after taking a 5 day dosage of azithromycin ?i was prescribed this for bronchitis

Anytime: If you're taking antibiotics for bronchitis (not usually recommended as most colds & upper respiratory infections are caused by viruses that don't respond to antibiotics), then only reason to avoid/postpone sex is that you don't feel strong enough (aren't up for it - get it? sorry, couldn't resist!). Clearly if you're coughing up lots of phlegm, etc, you might not want to pass germs onto partner.
