Introduction
If you suffer from seasonal allergies hay fever or chronic hives you may be familiar with Xyzal (levocetirizine dihydrochloride). But have you ever wondered what exactly is inside this medication and how its ingredients work to relieve your symptoms?
In this detailed guide we shall break down the active and inactive ingredients in Xyzal their functions and any potential side effects or concerns you should know about. By the end you will have a clear understanding of what makes Xyzal an effective allergy relief solution.
Active Ingredient in Xyzal
The key active ingredient in Xyzal is:
Levocetirizine Dihydrochloride (5 mg per tablet or 2.5 mg per 5 mL in liquid form)
β What It Does: Levocetirizine is an antihistamine that works by blocking histamine receptors (H1 receptors) in the body. Histamines are chemicals released by the immune system in response to allergens causing sneezing itching runny nose and watery eyes. By blocking histamine Xyzal provides relief from allergy symptoms for up to 24 hours.
β Why It is Effective: Levocetirizine is a second-generation antihistamine meaning it causes less drowsiness compared to older antihistamines like Benadryl (diphenhydramine). It has a faster onset of action (30-60 minutes) and provides long-lasting relief.
β Who Should Take It?
- People suffering from seasonal allergies (hay fever)
- Those with perennial (year-round) allergies
- Individuals with chronic urticaria (hives)
π‘ Key Fact: Levocetirizine is the active enantiomer of cetirizine (Zyrtec) meaning it is a purified version that may have fewer side effects than cetirizine.
