I've been saving up some interesting info in a word file that ive gathered from various internet sites.. thought all you druggies out there would enjoy Dosage equivalents for benzodiazepines & miscellaneous tranquilizers & hypnotics: 20mg Ambien (zolpidem tartrate) = 1mg Ativan (lorazepam) = 0.5mg Halcion (triazolam) = 0.5mg Klonopin (clonazepam) = 25mg Librium (chlordiazepoxide HCl) = 20mg Restoril (temazepam) = 20mg Sonota (zaleplon) = 15mg Tranxene (clorazepate dipotassium) = 10mg Valium (diazepam) = 0.5mg Xanax (alprazolam). SSRI dosage equivalents: 20mg Celexa (citalopram hydrobromide) = 5mg Lexapro (escitalopram oxalate) = 50mg Luvox (fluvoxamine maleate) = 20mg Paxil (paroxetine hydrochloride) = 20mg Prozac (fluoxetine hydrochloride) = 50mg Zoloft (sertraline hydrochloride) = 75mg of Effexor (venlafaxine hydrochloride). One study has shown that Celexa (citalopram hydrobromide) is the best intermediary drug when rotating SSRIs. Although Effexor (venlafaxine hydrochloride) is not an SSRI, it's listed here because it is frequently confused for one, its discontinuation syndrome sucks worse than that of the SSRIs', and at 75mg it affects only serotonin anyway. Not sure how accurate these may be, but from experience I think most are bang on
