The onset of pseudomembranous colitis symptoms may occur during or after antibacterial treatment. It appears as a pale plaque on direct visualization of the mucosa by endoscopy and is sensitive to oral vancomycin or metronidazole. Pseudomembranous colitis may be associated with toxic megacolon, which can be life-threatening.

Some cases of erythema multiforme resembled Stevens-Johnson syndrome.
Rare cases of leukocytoclastic angiitis, toxic epidermal necrolysis, erythema multiforme, and Stevens-Johnson syndrome associated with clindamycin hypersensitivity have been reported.
Rash was particularly common in AIDS patients.
A 47-year-old female patient with multiple comorbidities was diagnosed with Sweet's Syndrome. The patient's symptoms developed 2 days after initiating oral clindamycin (the active ingredient contained in Cleocin) therapy for a tooth infection. The patient's symptoms persisted despite tooth extraction and continuance of antibiotic treatment with intravenous, then oral, clindamycin. Following discontinuation of clindamycin, the patient's symptoms resolved over several days. Drug-induced Sweet's syndrome was determined based on the temporal relationship of the patient's symptoms, the beginning and end of clindamycin therapy, and the exclusion of other etiologies.
Three days after starting oral clindamycin for the persistence of symptoms following a root canal, a 34-year-old male patient reported "pimples" on his scalp which changed to pustules 24 hours later. The lesions progressed and the patient's antibiotic therapy was discontinued. Two days later, the rash improved considerably. The patient met the diagnostic criteria for drug-induced Sweet's syndrome and clindamycin was the most likely cause due to the timeline of antibiotic therapy and the patient's improvement following its discontinuation.
Rare (less than 0.1%): Exfoliative dermatitis, erythema multiforme, Stevens-Johnson syndrome, drug-induced Sweet's syndrome (at least 2 cases)
Frequency not reported: Pruritus, maculopapular rash (generalized pruritic), vesiculobullous rash, urticaria, acute generalized exanthematous pustulosis
