Should people with history of heart palpitations take azithromycin? I'm taking it and had heart palpitations. I've had history of anxiety.

Anxiety. Your doctor should know your history so he/she can prescribe therapy appropriate for your situation. Azithromycin is ok for most patients with benign palpitations. There are some people who might have problems with the drug and prescribing doctors should be able to judge who they are.
