Benzodiazepine Dose Equivalence (tapering converter)
Benzodiazepine dose-equivalence converter for tapering.

Example
- Source benzodiazepine
- Lorazepam
- Source dose
- 2 mg
- Target benzodiazepine
- Diazepam
Result: 2 mg lorazepam ≈ 10 mg oral diazepam (VA/DoD 2021) or 20 mg (Ashton 2002).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- VA/DoD 2021 (mg ≈ 10 mg diazepam)
- alprazolam 1, chlordiazepoxide 25, clonazepam 1, clorazepate 15, estazolam 1, flurazepam 15, lorazepam 2, oxazepam 30, quazepam 10, temazepam 15, triazolam 0.25.
- Ashton 2002 (mg ≈ 10 mg diazepam)
- alprazolam 0.5, clonazepam 0.5, lorazepam 1, oxazepam 20, quazepam 20, temazepam 20, triazolam 0.5, estazolam 1-2, flurazepam 15-30; others as VA/DoD.
- Safety
- A tapering planning estimate, not a prescription. Individualize to patient response; long half-life agents (diazepam, chlordiazepoxide) accumulate. Confirm with an independent check.

How this is calculated
- Method
- Factors are mg of the drug ≈ 10 mg oral diazepam. The source dose converts to a diazepam equivalent, then to the target. The two systems differ, so both are shown.
