Can clindamycin be taken together with doxycycline?

Yes but not sure why: Doxycycline 'covers' the same bacteria as are treated with clindamycin and has a better side-effect profile. So I'm not sure 'why' you would be taking both at the same time. With dual antibiotics, you have a higher chance of side-effects. Maybe this is just a short-term treatment, so it wouldn't matter so much. Hope you can improve there.
