Discussions that mention benadryl

High & Low Blood Pressure board

I was just prescribed this yesterday also. It dropped my BP a lot just in one dose (from 165/111 to several readings of 123/75-85 range); however, all day yesterday my hands, feet and scalp were itching like crazy. I took some Benadryl last night and it went away. If if happens after my dose today, I will know it's the Benicar and will call my dr.
