Dalacin C is a prescription antibiotic that contains clindamycin hydrochloride, used to treat certain serious bacterial infections. It belongs to a class of antibiotics called lincosamides and works against specific gram-positive and anaerobic bacteria. Because clindamycin carries a known risk of antibiotic-associated colitis, healthcare providers usually reserve it for infections where safer alternatives are not appropriate.
Dalacin C is a brand name for clindamycin used in several countries. In the United States, clindamycin is available under various brand and generic names. The Dalacin C capsules offered here contain clindamycin hydrochloride and are used for the same approved indications as U.S.-marketed clindamycin products.
This ensures patients receive the same active ingredient and therapeutic effect, even if the brand name differs from what is commonly available in U.S. pharmacies.
