Do i take metronzidole and doxycycline together? and if so one each so ill take four a day?

What did ur doc say?: Always ask prescribing doc about how to take meds. In fact, before s/he pulls out pen/computer, tell doc everything you're taking, whether prescription or otherwise. That way, we can look for drug-drug interactions. Or DIY by using online interaction checkers. http://www.drugs.com/interactions-check.php?drug_list=940-0,1617-0 shows no interaction btwn ur antibiotics. Pharmacist is good source too
