What mg of Diphenhydramine Hcl should be taken, and how many times a day should it be taken, to efficiently manage an anxiety disorder. (a comparison would be my prescription: 25mg of Hydroxyzine Hcl - 3x/day for anxiety, and 1x/nightly for sleep.
What is the diphenhydramine hcl dosage instructions for anxiety management?

It can range from 25mg to 100mg I know my doctor won't prescribe more than 100mg 3x a day. I was put on buspar along with it but got headaches from it then I tried various ssris but had bad reactions to them so I started klonopin then Xanax.
To find the correct dosage you need to talk to your Doctor. This has several variables, like age, weight, extent of anxiety & what your body can handle.
