Benadryl One a Day tablets contain cetirizine dihydrochloride, which blocks the effects of histamine in your body. When you encounter an allergen, your body releases histamine, which triggers allergy symptoms. Cetirizine prevents histamine from affecting your cells, reducing symptoms like sneezing, runny nose, and watery eyes.
The medication starts working within one hour of taking it and provides relief throughout the day.
Take one 10mg tablet once daily with a glass of water. You can take the tablet with or without food. If you forget to take your dose, take it when you remember, but never take more than one tablet in 24 hours.
