RxMedCalc

This free library of clinical calculators and decision-support tools is designed for healthcare professionals who need quick reference at the point of care. It covers common tasks across emergency medicine, primary care, paediatrics, obstetrics, dosing, and other clinical settings, with tools built around internationally recognized clinical guidance.

The collection includes 62+ calculators and decision-support tools and is designed for fast access without an account. No login is required, and the site states that patient data is not stored or transmitted. This makes the library suited to clinicians looking for a lightweight, privacy-focused reference during everyday clinical work.

Key Features

62+ Clinical Calculators

The library brings a broad range of clinical calculations and decision-support tools into one place.

Instead of using separate resources for different specialties, healthcare professionals can access calculators covering emergency care, general medicine, paediatrics, obstetrics, dosing, and occupational health.

Rabies PEP Calculator

The collection includes tools for calculating rabies post-exposure prophylaxis requirements.

The rabies PEP tool supports:

• Vaccine scheduling
• RIG dose calculations
• Body-weight-based calculations
• Wound-category considerations

This provides a quick reference for working through rabies PEP-related calculations.

IV Drip Rate Calculator

Calculate common intravenous infusion parameters for clinical use.

The tool covers:

• Drops per minute
• mL per hour
• Total volume
• Infusion time
• Standard IV sets
• Paediatric IV sets

This makes it useful when clinicians need to quickly work out infusion rates at the point of care.

Guideline-Based Clinical Scores

The library includes established clinical scoring and assessment tools such as:

• CURB-65
• NEWS2
• Glasgow Coma Scale (GCS)
• Wells criteria

These calculators provide structured reference points for clinical assessment and decision support.

Specialty-Based Organization

Tools are grouped into clinical areas to make relevant calculators easier to find.

Categories include:

• Emergency and critical care
• Paediatrics and neonatology
• General medicine and dosing
• Obstetrics and gynaecology
• Occupational health

This organization allows clinicians to navigate directly to the type of calculation or decision-support tool they need.

Built For Healthcare Professionals

The library is positioned as clinical decision support for qualified healthcare professionals.

It can be useful for:

• Physicians
• Clinicians in emergency care
• Primary care professionals
• Paediatric healthcare professionals
• Obstetric and gynaecology professionals
• Healthcare workers handling medication dosing
• Other qualified professionals needing point-of-care calculations

Common Use Cases

Point-of-care calculations: Quickly perform clinical calculations while working with patients.

Emergency medicine: Reference scoring systems and calculations relevant to emergency and critical care.

Medication and dosing: Use general medicine and dosing tools for common clinical calculations.

Paediatrics: Access paediatric and neonatal calculators, including tools where weight-based calculations are relevant.

Obstetrics: Use calculators and metrics relevant to obstetrics and gynaecology.

Clinical risk assessment: Work through established scoring systems such as CURB-65, NEWS2, GCS, and Wells criteria.

Infusion calculations: Calculate IV drip rates, infusion times, and volume-based parameters.

Guidance-Based Clinical Tools

The calculators are built against recognized clinical guidance from organizations and professional bodies listed by the site, including:

• WHO
• NICE
• ACOG
• BTS
• GINA
• ADA
• KDIGO

The library also covers both internationally used equations and localized risk stratification approaches, including BMI classifications and obstetric metrics.

Privacy-Focused Point-of-Care Reference

The platform is designed to be used without creating an account. The site states that no patient data is stored or transmitted, supporting a lightweight workflow for clinicians who need quick access to calculations without maintaining a separate user profile.

The focus is on using the tools as a clinical reference rather than creating another system for storing patient information.

Broad Clinical Coverage in One Library

Many clinical calculators are available individually, but finding the right tool can become difficult when working across multiple specialties. This library brings more than 62 calculators and decision-support tools into a single resource.

Its specialty-based organization makes it possible to move between emergency calculations, paediatric tools, dosing references, obstetric metrics, and occupational health resources without switching between separate calculator sites.

Why It Matters

Clinical calculations often need to be performed quickly and accurately during patient care. Having a broad set of recognized calculators in one place can reduce the need to search for individual formulas or tools while working.

This library focuses on fast, free, privacy-conscious clinical decision support, combining more than 62 calculators with specialty groupings and guidance from recognized medical organizations. It is intended as a reference for qualified professionals rather than a replacement for clinical judgment.

Access Free Clinical Calculators at the Point of Care
