Pharmacy & Drug Dosing Calculators
Calculate IV drip rates, opioid MME, pediatric doses, warfarin and gentamicin dosing, and renal dose adjustments.
This category currently includes 8 tools, including IV Drip Rate, Opioid MME, and Pediatric Dose.
These resources are built for clinicians, trainees, and medically informed patients who need fast bedside calculations. Use the results as decision support and pair them with full clinical context and local guidelines.
All Pharmacy Tools (8)
IV Drip Rate
Calculate IV infusion rates in mL/hr and drops per minute from volume, time, and drop factor. Essential nursing and pharmacy calculator for safe, accurate IV fluid and medication administration.
Opioid MME
Calculate morphine milligram equivalents (MME) for opioid medications using CDC conversion factors. ≥50 MME/day warrants caution; ≥90 MME/day carries significantly increased overdose risk.
Pediatric Dose
Calculate pediatric medication doses based on patient weight (mg/kg). Essential for safe pediatric prescribing.
Warfarin Guidance
Get warfarin dose adjustment guidance based on current INR and target range. Helps manage anticoagulation therapy.
Gentamicin Dosing
Calculate gentamicin dose and interval using extended-interval (5–7 mg/kg q24h) or traditional q8–12h dosing methods based on creatinine clearance and adjusted body weight.
Renal Dosing
Get renal dosing guidance by eGFR stage for antibiotics, anticoagulants, metformin, NSAIDs, and 20+ drug classes using CKD staging.
POSS Scale
Classify opioid-related sedation severity (S, 1, 2, 3, 4) and map to common bedside action guidance.
Ramsay Scale
Classify sedation depth from 1 to 6 using the Ramsay Sedation Scale to support bedside sedation monitoring.
