Since Atarax (hydroxyzine) helps temporarily, the rash is likely responsive to antihistamines, but we need to find the root cause. For daily management, a non-drowsy antihistamine like cetirizine or fexofenadine can help prevent breakouts. However, because the rash keeps returning, it is important to consult a doctor or dermatologist. They can help identify triggers?like allergies or stress?and discuss targeted treatments, such as topical corticosteroids. Please be reassured that this is very common and manageable. A medical evaluation will help you find lasting relief.
