Two different dr's have prescribed Hydroxyzine HCL for allergies and Hydroxyzine PAM for nausa with my pain meds. My regular dr doesn't believe they are different although they seem to react different in my body and my pharmacist agrees. Are they different?
The active ingredient, hydroxyzine, is the same in both formualtions, though the salt, pamoate or hydrochloride, to which it is attached is different. The pamoate comes as a capsule and the hydrochloride is a tablet. The release mechanism into the body is different between the two and hence why one may work better for you. Both the doctor and the pharmacist are correct. The doctor is looking at the active ingredient, hydroxyzine, which is what controls the symptoms of allergies and nausea, while he pharmacist is looking at the salt formulation which can affect how it is absorbed into your body.
Hydroxyzine is used for numerous unrelated medical conditions. I had been taking it for quite a while for allergies before finding out that it's commonly prescribed for anxiety! Sometimes it's even prescribed for sleep (though it doesn't personally make me drowsy). But the first commentor is correct. They're the same drug, just in different formulations.
