Of 298 outpatients receiving clindamycin for a variety of indications, diarrhea developed in ten (3.4%); none were diagnosed as having pseudomembranous colitis. This is well within the range of relative frequencies of diarrhea development (0% to 22.2%) reported in 45 previous studies. Reliance solely on computer-recorded instances of diarrhea yielded a substantial underestimate of diarrhea occurrence, but the rate was still significantly higher (P <.05) in clindamycin users than in nonusers.
