Zyrtec is also known by the generic name Cetirizine


USES:
This medication is an antihistamine that treats symptoms such as itching, runny nose, watery eyes, and sneezing from "hay fever" and other allergies. It is also used to relieve itching from hives.

Cetirizine does not prevent hives or prevent/treat a serious allergic reaction (e.g., anaphylaxis). Therefore, if your doctor has prescribed epinephrine to treat allergic reactions, always carry your epinephrine injector with you. Do not use cetirizine in place of your epinephrine.

If you are self-treating with this medication, it is important to read the manufacturer's package instructions carefully so you know when to consult your doctor or pharmacist. (See also Precautions section.)

Atarax is also known by the generic name Hydroxyzine Hcl


USES:
Hydroxyzine is used for the short-term treatment of nervousness and tension that may occur with certain mental/mood disorders (e.g., anxiety, dementia). It is also used to treat itching from allergies and other causes (e.g., reactions to certain drugs). It may also be used to help you feel calmer before/after surgery, or to help certain narcotic pain relievers (e.g., meperidine) work better.

Hydroxyzine belongs to a class of medications called antihistamines. It works by blocking a certain natural substance (histamine) that your body makes during an allergic reaction. Its other effects (e.g., calming, pain relief) may work by affecting other natural substances (e.g., acetylcholine, serotonin) or by acting directly on certain parts of the brain.
