Tablet / Capsule Quantity Calculator
Calculates tablets per dose and total tablets to dispense for a complete treatment course.
⚠️ Educational Calculation & Clinical Safety Safeguard: If Units/Dose is <0.5 or >4 tablets, verify strength selection to prevent administration errors. Educational calculations do not replace clinician assessment, patient-specific laboratory monitoring, or institutional prescribing protocols.

Step-by-Step Mathematical Derivation & Explanation:
Validated Formula & Conversion Rules
Units/Dose = Desired Dose / Strength; Total Dispensed = Units/Dose × Doses/day × Duration (days)Worked Clinical Example
Prescribed 500 mg TID for 5 days using 250 mg capsules: 500/250 = 2 capsules/dose; Total = 2 × 3 × 5 = 30 capsules.
Rounding Rules, Assumptions & Source References
- Rounding Rule: Do not split enteric-coated, modified-release (SR/XR), or unscored capsules.
- Clinical Assumptions & Limitations: Validated only within the stated physiological input boundaries. For paediatric, renal (Cockcroft-Gault), and critical-care infusion calculations, always cross-check against official product labelling and institutional guidelines.
