Drip Rate Calculator Free

Weight-based pressors, sedation, and continuous infusions — auto-converted between mcg/kg/min, mcg/min, units/hr, and mL/hr. Includes preset concentrations for the most common ICU/ED drips, plus titration step calculator.

⚠ Reference only — verify before administering. This is a study and double-check aid, not a clinical decision tool. Always verify dose, concentration, infusion rate, and compatibility against your institution's formulary, the package insert, and a second licensed verifier (per ISMP high-alert medication guidelines) before initiating or titrating any drip. Concentrations below are common defaults — your facility may use different.
