Xyzal 5 mg (Levocetirizine): Uses, Dosage, Side Effects, Safety, and Frequently Asked Questions

What Is Xyzal 5 mg?

Xyzal 5 mg is a second-generation antihistamine containing the active ingredient levocetirizine dihydrochloride. It is used to relieve symptoms caused by allergic rhinitis (hay fever and year-round allergies) and to treat chronic idiopathic urticaria (long-lasting hives).

Unlike many older antihistamines, Xyzal is less likely to cause drowsiness, although some people may still experience sleepiness.

Xyzal is available in several forms, including:

• 5 mg tablets
• Oral solution (commonly used for children)
• Generic levocetirizine products

How Xyzal Works

During an allergic reaction, the body releases histamine, a chemical responsible for symptoms such as sneezing, itching, watery eyes, and a runny nose.

Xyzal works by:

• Blocking histamine H1 receptors.
• Preventing histamine from causing allergy symptoms.
• Reducing itching, sneezing, watery eyes, and skin reactions.

It begins working within about an hour for many people and can provide symptom relief for up to 24 hours.
