Relative Potency Of Benzodiazepines


Relative potency of benzodiazepines will give you a general idea of how strong of a dose, in milligrams, it would take to produce results equal to ingesting 20 milligrams of diazepam (valium).

Everyone is different so results will vary, but this will be helpful if you are switching from one benzodiazepine to another. You can figure out what size of a dose will provide similar results when comparing between any of the medications listed.
