hydroxyzine HCl IM 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 help manage withdrawal symptoms (e.g., anxiety, agitation) in alcoholics. Other uses include helping to decrease anxiety and nausea before/after surgery or during childbirth or helping certain narcotic pain relievers (e.g., meperidine) work better.
Hydroxyzine belongs to a class of medications called antihistamines. It is thought to work by affecting certain natural substances (acetylcholine, serotonin) in your body or by acting directly on certain parts of the brain. Hydroxyzine also blocks a natural substance that your body makes during an allergic reaction (histamine).How to use hydroxyzine HCl IM
