Description
Atarax (hydroxyzine hydrochloride) is an FDA-approved antihistamine that is used to treat anxiety, relieve itching from allergic conditions, and provide sedation before and after surgery. It may also be prescribed short-term to help with sleep difficulties
Atarax is not usually used for long periods to treat anxiety. If you stop taking it after using it for some time, you may notice symptoms like restlessness or trouble sleeping.
These are signs of Atarax withdrawal, and your doctor may help you slowly stop the treatment to avoid them.
Indications and Benefits of Atarax
- Anxiety relief
- Itching and allergy symptom control
- Sedation before surgery
- Helps improve sleep
- Can help relieve itching associated with chronic hives (urticaria) or eczema
- Provides calming effects during allergic reactions
How It Works
Atarax works by blocking a natural chemical called histamine, which is responsible for causing itching, swelling, and allergic reactions.
It also affects serotonin, a chemical in the brain related to anxiety and stress.
By influencing these two chemicals, Atarax reduces allergic symptoms and produces a calming, sedative effect.
Dosage
Doctors adjust the Atarax dose based on your age, the condition being treated, and how your body responds to the medication. It comes in tablet, syrup, and injectable forms.
Follow your doctor’s instructions closely to get the best results from Atarax. Taking too much can increase the risk of side effects, so never go beyond the Atarax max dose without medical advice.
Dosage Form and Strengths of Atarax
Atarax comes in different forms to suit patients of all ages. These include tablets, syrup, and injections.
The strength and form your doctor prescribes will depend on your age, the condition being treated, and whether you need fast or long-lasting relief.
