STORAGE: Capsules, tablets, and liquids should be stored at room temperature 15 C to 30 C (59 F to 86 F). Liquid should not be frozen and should be shaken well prior to each use. Injectable hydroxyzine should be stored below 30 C (86 F).

DRUG INTERACTIONS: Hydroxyzine adds to (exaggerates) the sedating effects of alcohol and other drugs that can cause sedation such as the benzodiazepine class of anti-anxiety drugs (for example, diazepam [Valium], lorazepam [Ativan], clonazepam [Klonopin], alprazolam [Xanax]), the narcotic class of pain medications and its derivatives (for example, oxycodone and acetaminophen [Percocet], hydrocodone/acetaminophen [Vicodin], hydromorphone [Dilaudid], codeine, propoxyphene [Darvon]), the tricyclic class of antidepressants (for example, amitriptyline [Elavil, Endep], imipramine [Tofranil], desipramine [Norpramin]), and certain antihypertensive medications (for example, clonidine [Catapres], and propranolol [Inderal]). Hydroxyzine can also intensify the drying effects of other medications with anticholinergic properties (for example, dicyclomine [Bentyl], bethanechol [Urecholine], Probanthine, amitriptyline [Elavil, Endep], and chlorpromazine [Thorazine]). When using these drugs, the dose of hydroxyzine may require reduction.
