Allegra (fexofenadine) is an antihistamine that temporarily blocks the chemicals causing your symptoms, but it does not cure the underlying trigger. When the medication wears off, or if you are continuously exposed to the allergen, your symptoms can return. Since taking 180 mg twice daily is higher than the standard dosage, it is very important to consult a healthcare professional. They can help identify the root cause of your symptoms and guide you toward a safer, more effective long-term treatment plan.
