Hydroxyzine is available both by prescription and over-the-counter (OTC) in the United States for certain uses [1].
What is hydroxyzine used for OTC?
Over-the-counter hydroxyzine pamoate is primarily indicated for the temporary relief of the symptoms of hay fever and other allergic conditions, such as itching and runny nose [2]. It is also used for the management of skin itching caused by allergic reactions [2].
What is the difference between prescription and OTC hydroxyzine?
While the active ingredient is the same, the key difference lies in the dosage and the conditions for which they are approved [1, 2]. Prescription hydroxyzine can be used for a wider range of conditions, including anxiety, nausea, vomiting, and as a sedative before surgery, and may be available in different formulations and strengths [1]. Over-the-counter formulations are typically lower in strength and limited to allergy symptom relief and itching [2].
Can I buy hydroxyzine without a prescription?
Yes, hydroxyzine pamoate is available without a prescription for specific indications like hay fever symptoms and itching associated with allergies [2]. However, for other uses such as anxiety or pre-operative sedation, a prescription is required [1].
What are the common side effects of hydroxyzine?
Common side effects of hydroxyzine include drowsiness, dry mouth, and dizziness [2]. It is important to avoid driving or operating heavy machinery after taking hydroxyzine due to its sedative effects [2].
How long does OTC hydroxyzine take to work?
OTC hydroxyzine typically begins to relieve symptoms within 15 to 30 minutes of administration [2].
When does the patent for hydroxyzine expire?
Hydroxyzine is an older medication with a long history, and its original patents have long since expired. This has allowed for the widespread availability of generic versions [3].
Can I take hydroxyzine for anxiety without a prescription?
No, hydroxyzine is not approved for treating anxiety without a prescription [1]. For anxiety management, a doctor's consultation and prescription are necessary.
Are there other OTC antihistamines for allergies?
Yes, numerous other over-the-counter antihistamines are available for allergy relief, including diphenhydramine (Benadryl), loratadine (Claritin), cetirizine (Zyrtec), and fexofenadine (Allegra) [4]. These medications differ in their side effect profiles, particularly regarding drowsiness [4].
