I have a cold and am on an antibiotic, doxycycline, is it dangerous to start taking trinessa while?
It is not dangerous for you to take Trinessa with doxycycline but you will need extra contraception while taking doxycycline and for 7 days after the last dose. So if you haven’t started Trinessa yet, probably wait until you finish the course of doxycycline (I’m assuming it’s a short course as you have a cold).
