Hydroxyzine belongs to the chemical group of ethanol. It is a chemical substance that counteracts histamine receptors. This is why it is used as an antihistamine, providing relief for certain allergies, and it is also used as an anxiolytic. This substance is, however, known to cause side effects such as vomiting, drowsiness, intestinal dysfunction, urine retention, and, in rarer cases, blurred vision and convulsive seizures, among others.
