Diphenhydramine (Benadryl) dosing ranges

Does anyone know where I might find info. re: dosing ranges using Benadryl to give an addative affect to narcotics? I cannot find the info in my Davis Drug Guide.

Merry Christamas to all,

Rarely see docs use it as such, but when they do, generally 25 mg IVP.

We use it in combo with LIBRIUM for sleep/anxiety, 25-100mg via PO q6hrs prn. We try to keep the BENADRYL under 50mg when combining with the LIBRIUM.
