Levocetirizine Dihydrochloride is the stable salt form of the antihistamine levocetirizine, designed to inhibit the effects of histamine in the body. It is indicated for the symptomatic relief of allergic rhinitis and uncomplicated skin manifestations of chronic idiopathic urticaria. This ingredient is found in many cost-effective generic allergy medications. We provide a licensed platform for purchasing authentic treatments containing Levocetirizine Dihydrochloride to help manage your daily allergy symptoms.
Levocetirizine dihydrochloride is a second-generation antihistamine, a type of medicine that blocks the action of histamine - a natural chemical released during an allergic response. By stopping histamine from binding to its receptors, it helps relieve common allergy symptoms such as sneezing, itching and a runny nose. This active ingredient is found in products marketed under the name Levocetirizine.
In the UK, Levocetirizine is available as a tablet and as a syrup for those who prefer a liquid form. The most widely recognised brand name is Xyzal, which contains levocetirizine dihydrochloride as the sole active substance. Generic levocetirine tablets are also supplied by several pharmaceutical companies and are listed on the NHS formulary. Strengths commonly seen are 5 mg tablets and 2.5 mg/5 ml syrup, but the exact dosage and packaging can differ between brands. All of these products share the same active ingredient, levocetirine, though they may vary in size, shape or additional inactive components.
Levocetirine dihydrochloride is used to manage several allergic conditions:
These uses are approved by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK. Some clinicians may prescribe levocetirine for other allergy-related symptoms, but any off-label use should be guided by a qualified healthcare professional.
When an allergen enters the body, cells release histamine, which attaches to receptors in the nose, eyes and skin, causing the typical allergy signs. Levocetirine dihydrochloride competes with histamine for these receptors, preventing the chemical from triggering the allergic response. Because it does not readily cross into the brain, it usually causes less drowsiness than older antihistamines. Most people notice relief within a few hours, and the effect can last through the day with a single dose.
These effects are usually short-lived and resolve without needing any special action.
Although rare, some individuals may experience more serious signs such as:
If any of these occur, seek urgent medical help.
