Can i take metronidazole and dalacin c together?

Unusual but possible: It would be unusual to take both metronidazole (Flagyl® and generics) and clindamycin (Dalacin C® and other brands). But there could be complex infections that might be treated with both, esp. if you can't tolerate more usual antibiotics. If both were prescribed for a particular infection, follow that advice. But if prescribed by two doctors for separate problems, contact both for their advice.
