It sounds distressing to have your allergy symptoms return after stopping the medication. Since your symptoms include itchy red spots that worsen with rubbing, warmth, and difficulty breathing, this suggests a significant allergic reaction that needs careful management.

• You should contact your allergist or dermatologist promptly to discuss the recurrence and severity of your symptoms.
• It may be necessary to restart or adjust your antihistamine treatment, such as Artazin (hydroxyzine), under medical supervision.
• Because difficulty breathing can indicate a serious allergic reaction, seek immediate emergency care if this symptom worsens or you experience swelling of the face, lips, or throat.
• Avoid known triggers or allergens as much as possible until you have a clear management plan.
• Follow up with your doctor for possible allergy testing or additional treatments like corticosteroids or epinephrine if recommended.
