Both Claritine and Atarax are used to relieve allergy symptoms, but they belong to two different generations of antihistamines, resulting in differences in how they work, their side effects, and their uses. Understanding these differences helps determine the most appropriate medication to effectively relieve allergy symptoms.
Claritine Tablets Ingredients
Claritine tablets contain the active ingredient loratadine. Loratadine is a second-generation antihistamine, which is less drowsy than first-generation antihistamines. Loratadine works by blocking the effects of histamine, a chemical released by the body in response to allergens that causes symptoms such as itching, sneezing, runny nose, and red eyes.
Atarax Tablets Ingredients
Atarax tablets contain the active ingredient hydroxyzine hydrochloride. Hydroxyzine is a first-generation antihistamine that also blocks histamine but more easily crosses the blood-brain barrier, resulting in powerful sedative and analgesic effects. In addition to its antihistamine effect, hydroxyzine has other properties, such as anxiolytic and anticholinergic effects.
