Reactine Extra Strength Rapid Dissolve 10 mg tablets dissolve in seconds on the tongue without water — no need to swallow a pill. Each oral-disintegrating tablet starts working fast on allergy symptoms and provides up to 24 hours of long-lasting relief.
Active ingredient: Cetirizine hydrochloride 10 mg per rapid-dissolve tablet. Pack of 24 tablets.
Relieves: Sneezing, runny nose, itchy and watery eyes, itchy nose and throat, hives and skin itching due to seasonal allergies (hay fever), pet dander, dust mites, and indoor or outdoor allergens.
Adult dosage: One tablet daily, with or without water. Place on the tongue and let it dissolve. Suitable for adults and children 6 years and older.
Why it stands out: Cetirizine is a second-generation antihistamine — relief without the heavy drowsiness common to first-generation products like diphenhydramine. The rapid-dissolve format is convenient when traveling, at work, or for anyone who has trouble swallowing tablets.
Cautions: May cause drowsiness in some people. Speak with a pharmacist if you have kidney disease, liver disease, or are pregnant or breastfeeding before use.
