A member asked:

On the pill. had sex with no condom 3 days after i finish my doxycycl meds. pregnancy? are bc pills still ineffective 3 days after finishing doxycycl?

A doctor has provided 1 answer

BCP's and antibiotic: Broad spectrum antibiotic(which doxycycline) is, will lower the effectiveness of BCP's. It is prob the best idea to consider the entire BCP cycle as compromised. When you take antibiotics, you should continue with your BCP but also use additional method of BCP during the entire cycle. ie, BCP + condom
