How to Calculate Clindamycin 75 mg/5 mL (suspension) Dose

This calculator determines the Clindamycin dose for treating bacterial infections, using a concentration of Clindamycin 75 mg/5 mL (15 mg/mL), based on the patient’s weight and dosage regimen:

Dose in mg and Volume in mL (based on Clindamycin component):

Volume Calculation:

Where:

• Weight: Patient’s weight in kilograms or pounds (minimum ~5 kg for pediatric >1 month, automatically converted to kg).
• Dosage Regimen: Select from 8 to 12 mg/kg/day TID, 8 to 12 mg/kg/day QID, 13 to 16 mg/kg/day TID, 13 to 16 mg/kg/day QID, 17 to 25 mg/kg/day TID, or 17 to 25 mg/kg/day QID.
• Concentration: Clindamycin 15 mg/mL (75 mg/5 mL).

For adults, the usual dose is 150 to 600 mg po TID to QID. Administer for 7–10 days, or as directed. ⚠️ Always consult a healthcare provider.
