* Anaerobic gram-negative bacilli, including: Bacteroides species (including Bacteroides fragilis group and Bacteroides melaninogenucus group), Fusobacterium species.

* Anaerobic gram-positive non spore forming bacilli, including: Propionibacterium, Eubacterium, Actinomyces species. Anaerobic and microaerophilic gram-positive cocci, including: Peptococcus species, Peptostreptococcus species, Microaerophilic streptococci.

Rare instances of erythema muttiforme, some resembling Stevens-Johnson syndrome, and a few cases of anaphylactoid reactions have also been reported. Jaundice and abnormalities in liver function tests have been observed during clindamycin therapy. Transient neutropenia (leukopenia) and eosinophilia have been reported. Clindamycin has been shown to have neuromuscular blocking properties that may enhance the action of other neuromuscular blocking agents. Therefore, it should be used with caution in patients receiving such agents. Opposition has been confirmed between clindamycin and erythromycin. Do not take these antibiotics at the same time.
