About InsulinPoint
A free, evidence-based clinical insulin decision-support tool — built for patients, pharmacists, and diabetes care teams.
Our Mission
Insulin dosing is one of the most complex, high-stakes calculations in everyday diabetes management. Errors — even small ones — can result in dangerous hypoglycemia or uncontrolled hyperglycemia. Yet most patients and even many clinicians rely on mental math, outdated charts, or confusing smartphone apps.
InsulinPoint was created to bring the full precision of pharmacy-grade clinical rules directly to your browser — free, private, and always accessible. No account registration. Zero clinical data collection.
What InsulinPoint Calculates
Meal Bolus (500 Rule)
Calculates your Insulin-to-Carb Ratio (ICR) using the 500 Rule: ICR = 500 ÷ TDD. Then computes the exact units needed for any carbohydrate intake.
Correction Bolus (1800 Rule)
Derives your Insulin Sensitivity Factor (ISF) via the 1800 Rule: ISF = 1800 ÷ TDD. Computes exact correction units based on your current vs. target glucose.
Active IOB Decay Guard
Models exponential insulin-on-board decay across rapid, regular, and mixed insulin types. Prevents dangerous stacking by factoring remaining active insulin.
TDD & Basal/Bolus Split
Profiles your Total Daily Dose and calculates the recommended 50/50 basal-to-bolus split. Estimates starting doses from body weight for newly initiated insulin therapy.
Rx Days Supply & BUD
Calculates pharmacy days supply from vial size, concentration, and daily dose. Applies FDA Beyond-Use Dating (BUD) rules for opened insulin pens and vials.
Clinical Reference & FAQ
Comprehensive 800+ word clinical education guide covering insulin types, dosing principles, safety rules, and commonly asked patient questions.
Design Philosophy
- ✓ Privacy-first: All calculations run entirely in your browser. No form data, glucose readings, or personal information is ever transmitted or stored on a server.
- ✓ Evidence-based: Every formula is sourced from established clinical pharmacokinetic rules used by endocrinologists, CDEs, and clinical pharmacists.
- ✓ Always free: InsulinPoint is and will remain completely free with no subscriptions, premium tiers, or paywalls. Accurate clinical insulin dosing tools should be accessible to everyone.
- ✓ Dual unit support: All blood glucose values support seamless switching between mg/dL (US) and mmol/L (international) — without reloading or re-entering data.
