Can I Take Zithromax Before my Surgery on Monday?

Thnakd for your question.  I could not tell when your surgery was scheduled for and I am assuming you have a strep throat infection?  I would reccomend if you were my patient to treat the infection and wait at least 10 days - 2weeks prior to elective surgery.   Please communicate with your surgeon. 

I'm sorry to hear about the infection and its poor timing. Unfortunately, online consultation is not the way to go here; you need to communicate with your plastic surgeon...

Best wishes.
