Benzodiazepine Conversion Calculator

How to Use Benzodiazepine Conversion Calculator

The Benzodiazepine Conversion Calculator estimates an equivalent daily dose between common benzodiazepines. Select the current drug, enter the current daily dose in mg, then select the target drug. The calculator converts the current dose to a diazepam-equivalent amount and then converts that amount to the target drug.

The result panel displays the estimated target daily dose and the intermediate diazepam equivalent. This makes the conversion traceable and easier to audit. The table in the calculator uses fixed equivalence anchors, so the output is best understood as an approximate comparison rather than a precise prescription.

Benzodiazepine switching and tapering can be risky. Sedation, withdrawal, seizures, respiratory depression, alcohol or opioid co-use, older age, pregnancy, liver disease, and psychiatric context all matter. A clinician should supervise medication changes.

Formula & Theory - Benzodiazepine Conversion Calculator

The Benzodiazepine Conversion Calculator uses:

Target dose = current dose / current equivalent dose x target equivalent dose

The implemented diazepam-equivalent anchors are:

Diazepam 10 mg
Lorazepam 1 mg
Alprazolam 0.5 mg
Clonazepam 0.5 mg
Temazepam 20 mg
Oxazepam 15 mg

For example, converting lorazepam 1 mg/day to diazepam:

1 / 1 x 10 = 10 mg/day diazepam equivalent

Use Cases for Benzodiazepine Conversion Calculator

The Benzodiazepine Conversion Calculator is useful for pharmacology education, medication reconciliation examples, tapering discussions, and explaining why different benzodiazepines cannot be compared milligram-for-milligram.

Use the output only as an approximate educational estimate. Real conversion plans require prescriber oversight and patient-specific adjustment.
