Taking Amoxicillin and Doxycycline, is it safe?
BreeCortez07 posted:
I am curious if it is safe to take these two medicines, (Amoxicillin and Doxycycline)?

please post back.
Amelia_WebMD_Staff responded:
Hi Bree!

After putting these two medications into the Medscape Interaction Checker , it seems that there is a serious interaction. "doxycycline decreases effects of amoxicillin by pharmacodynamic antagonism. Serious - Use Alternative."

Please check the site here and speak with your doctor before taking and/or combining any medication.

Take care!
