Benzodiazepine Equivalence Calculator

Convert a dose of any common benzodiazepine into its diazepam equivalent, and back out again to another agent. Equivalence ratios follow published clinical pharmacology sources rather than a single house table.

What the calculator gives you

• Diazepam-equivalent dose for the agent and dose you enter
• The equivalent dose in any other listed benzodiazepine
• Half-life and onset for the agents being compared
• The published source behind each equivalence ratio

Equivalence ratios are approximations from clinical pharmacology, not from randomised trials, and individual response varies. For clinical decision support only. Not a substitute for professional judgment.
