Is clindamycin 300mg q12 hours often enough for an infection after a root canal or should it be taken q8h or q6?

Consult with dentist: The Usual Adult Dose for Bacterial Infection is Oral: A serious infection: 150 to 300 mg orally every 6 hours A more severe infection: 300 to 450 mg orally every 6 hours. However, I highly suggest you consult with your dentist about the dose you should be taking.

Depends: Antibiotic dosing for an adult for a systemically involved dental infection using Clindamycin at a strength of 300mg is recommended Q8h for a constant blood level. It should be noted however that there are many variables that may affect that recommendation. I suggest that you discus this with the prescribing DDS for the best answer. Good luck -

Adult Dose: Dental infection 150 to 300 mg orally every 6 hours for at least 7 days.
