I am on the cerezette pill and also penicillin for tonsillitis, do the antibiotics make the pill ineffective ? I had intercourse today and am due to have the implant tomorrow and I know you cant have the implant if there is any chance of you being pregnant. Should I take the morning after pill tomorrow will they still fit the implant ?
Hello. Thanks for writing to us. The antibiotics can decrease the efficacy of the pill by increasing its metabolism. It is best to use an additional protection like a condom in this cycle. I hope this information has been both informative and helpful for you.
