Effectiveness Relieves Allergy Symptoms: Allegra effectively reduces sneezing, runny nose, itchy or watery eyes, and throat irritation caused by allergens like pollen, dust, and pet dander.

People with kidney disease (dose adjustment needed) Avoid taking with fruit juices (grapefruit, orange, apple) as they reduce absorption Pregnant & breastfeeding women should consult a doctor before use Dosage & Usage Usual Dose: 120mg once daily with water Best taken before meals for better absorption Conclusion Allegra 120mg is a safe, effective, and non-drowsy option for allergy relief. However, always follow doctor’s advice for the best results.
