antibiotcs and birth control
I have been placed on two courses of antibiotics in one months after having my wisdom teeth removed. First right after the operation and later in the same month after it was not healing properly. Is it true that antibiotics have an effect on the pill?
I can't remember the names of the antibiotics but my pill is Nordette. I am worried that I have been unprotected all this time.

Worried, antibiotics like Ciprofloxacin, Clarithromycin, Co-trimoxazole and Erythromycin have very little effect on the pill. The risk of break-through bleeding and of pregnancy are very remote to nil, but my advice would be to rather be safe than sorry – take extra precaution for the duration of the treatment.
With antibiotics like Cephalexin, Chloramphenicol, Clindamycin, Metronidazole, Penicillin and Tetracycline the risk of break-through bleeding is high and the risk of falling pregnant is moderate. The best would be to take extra precaution for the duration of the treatment plus 7 days. In the case of long-term treatment extra precaution is only necessary for the first 4 weeks.
