"prescribed hydroxyzine a year ago for itching/rash/hives. worked extremely well. my skin cleared up and didnt need to take anymore. i also suffer with anxiety/panic attack/ agoraphobia and stress. heard that hydroxyzine can also be used for that. about 30 minutes ago i began having a severe anxiety/panic attack. my arm and face hurt, tingling/numbness, fear i am dying, etc. so i took two 25mg and hoping it will lesson all my panicky feelings. as of now symptoms have lessened but not gone. not extremely sleepy/tired but slight sedation. in the past with taking for the itching/hives and rash the sedation usually kicked in about an hour after taking. so it could do the same - which would be fine with me."
