Yes, hydroxyzine can be used for both itching and anxiety.
How hydroxyzine treats itching
Hydroxyzine is an antihistamine that blocks histamine H1 receptors, reducing allergic reactions like hives, rashes, and dermatitis that cause itching. The FDA approves it for symptomatic relief of pruritus due to allergic conditions.[1]
How hydroxyzine treats anxiety
It also has sedative effects via antihistamine and anticholinergic actions on the central nervous system, calming anxiety and tension. The FDA approves it short-term for anxiety relief and as a preoperative sedative.[1]
Usual doses for each use
For itching in adults: 25 mg three or four times daily. For anxiety: 50-100 mg four times daily, not exceeding 400 mg per day. Doses vary by age, condition, and form (capsules, syrup, injection).[2]
Common side effects and precautions
Drowsiness affects up to 40% of users, impairing driving or machinery use. Other effects include dry mouth, dizziness, and headache. Avoid in glaucoma, urinary retention, or with alcohol/MAOIs. Not for long-term anxiety due to tolerance and dependence risks.[2]
Why doctors prescribe it for both
Its dual action makes it convenient for patients with overlapping symptoms, like anxiety from chronic itching in atopic dermatitis. Studies show it reduces pruritus scores by 50-70% and anxiety comparably to low-dose benzodiazepines with less abuse potential.[3]
