Benzodiazepine Conversion Calculator

Convert Between Benzodiazepine Doses

Benzodiazepine conversion tables express each drug relative to alprazolam (Xanax). To switch agents, divide the current dose by the source drug factor, then multiply by the target drug factor. This calculator performs that conversion and displays a full equivalency table for common agents including diazepam, lorazepam, clonazepam, and midazolam.

Conversion Formula

$$\text{target dose (mg)} = \frac{\text{source dose (mg)}}{\text{source factor}} \times \text{target factor}$$

Important Clinical Notes

Equivalent doses are approximations. Half-life, onset, potency at receptors, and patient factors differ between agents. Cross-tapering under medical supervision is safer than abrupt switches. IV midazolam and oral midazolam use different factors because absorption and use cases differ.
