Quote from SMassmann:I am just relaying what my doctor has told me GLSheridan. Actually I do know someone that has had a interaction from antibiotics & she did end up pregnant.
My doc told me when i was on zithromax to use a back up method for a month...
He said it doesn't happen alot but it does happen.
Anyway! Good Luck HEYTEACH!
Zithromax is a macrolide, and that class of antibiotics does not affect the pill. There are some studies suggesting that antibitiocs such as Amoxil do affect the pill, but Zithromax isn't in the class.
Of course, it's better to be safe than sorry, but I'm right on this one.
