Hydroxyzine hydrochloride is used as an allergy treatment. It is an antihistamine and works by blocking the production of histamine, which is a natural substance that your body produces during an allergic reaction.
It is also known to be used short-term to treat anxiety, due to its sedative properties, and can even be used before and after surgery.
Hydroxyzine is the chemical name of the drug but pharmaceutical companies have many commercial names that you might have probably heard of, such as Vistaril or Atarax.

What if I am taking other drugs with Hydroxyzine?

“Does not make me sleepy or less anxious.”
Taken for 1 to 6 months

“Ok so my doctor’s PA gave me hydroxyzine to ease my nighttime itchiness (eczema) and it’s started making me shake severely, have tightness in my chest, and makes my breathing feel a little laboured. Unfortunately, she has me on other meds to which I’m beginning to believe I’m allergic to. Going to stop taking hydroxyzine until I can see my new doctor. Don’t ignore these horrible symptoms as they’re not normal! 3-5 hours to go before it’s supposed to work its way out of my system…this.is.awful.”

“my doctor prescribed me 25mg Hydroxyzine for my severe anxiety, social anxiety panic attacks and PTSD. I take 1/2 tabs four times daily as needed for my severe anxiety. I am giving this drug a 8 because it does NOT work with panic attacks but it does work amazing with anxiety. I am also on Xanax 1 mg as needed for my severe panic attacks which I usually have about 2-3 times a day. Some days are better and worst but Hydroxyzine been helping keep me calm. Also I am on 60mg of Cymbalta and this stuff works amazing. So with the combo xanax, hydroxyzine and cymbalta, my life is back to normal and social anxiety panic attacks and PTSD controlled and I feel myself again.”
