Benzodiazepine Conversion Calculator
Compare approximate equivalent doses between common benzodiazepines using diazepam-equivalent potency ratios.
About benzodiazepine conversion
Benzodiazepine conversion examples
| Conversion | Approximate result | Context |
|---|---|---|
| 1 mg alprazolam to diazepam | 20 mg diazepam | Uses a diazepam-equivalent factor of 20 for alprazolam. |
| 2 mg clonazepam to lorazepam | 4 mg lorazepam | Both are first converted through their diazepam-equivalent factors. |
| 10 mg diazepam to chlordiazepoxide | 25 mg chlordiazepoxide | The larger milligram result does not imply a stronger clinical effect. |
How to use the converter
- Choose the benzodiazepine currently being taken as the source medicine.
- Enter the source dose in milligrams and select the medicine to compare.
- Enter the number of daily doses if a total daily estimate is useful.
- Calculate the approximate equivalent and review it with a qualified clinician.
Benzodiazepine conversion FAQ
Are benzodiazepine equivalent doses exact?
No. Equivalency tables are approximate population-level guides, and published values can differ. A prescriber must account for response, half-life, health conditions, and other medicines.
Can I use this result to switch medicines myself?
No. Unsupervised switching or abrupt dose reduction can cause withdrawal, oversedation, or loss of symptom control. Discuss any medication change with the clinician who manages the prescription.
Why does half-life matter during conversion?
Half-life affects how quickly drug levels rise and fall and whether active compounds accumulate. A potency-equivalent dose of a shorter-acting medicine may not produce the same timing of effects as a longer-acting medicine.
Does the calculator create a taper schedule?
No. It only performs a dose-equivalence calculation and does not recommend a reduction rate. Taper schedules must be individualized according to duration of use, symptoms, dose, and clinical risk.
What does diazepam equivalent mean?
It expresses different benzodiazepine doses on one common potency scale based on diazepam. It helps compare strengths, but it does not erase differences in onset, duration, metabolites, or patient response.
