Effectiveness
How Xyzal Allergy 24Hr Affects PatientsLevocetirizine is a type of medication used to reduce the symptoms of allergies. It is usually taken once per day, and is considered safe as it takes a large amount to cause harm. Patients should be aware that this drug can make them drowsy, so they should avoid activities that require them to be alert. Those with a higher risk of urinary retention should be especially cautious when taking levocetirizine.
How Xyzal Allergy 24Hr works in the bodyLevocetirizine helps prevent the effects of histamines in the body. Histamines are chemicals that cause muscle contractions, allow fluid to move through vascular walls, stimulate cough receptors, and create flare responses in the nervous system. Levocetirizine stops these effects by blocking histamine from binding to its receptor.

12/19/2021 I tried the generic form of this medication, and it was completely ineffective. I could tell no difference whatsoever after taking it as directed.
