Oh god, don't remember me with clindamycin,
the only time i'd used it to manage ludwig's angina, 300 mg 3 times daily, 5 days
i had had sever diarrhea that was not responsive to Metronidazole 500 nor ciprofloxacin 750
so, i was advised for Vancomycin P.O and it showed help...
since that day, i sweared that i will not prescribe clindamycin(or at least with 4timed daily dosing!!!!)
You may want to call and ask him if the prescription is proper. The dentist can prescribe based upon his clinical judgement but generally, clindamycin is prescribed at 150 to 300mg every 6 hours, with 300mg being a stronger dosage to kill bacteria. He may be concerned with some side effects of the antibiotics.
