Wondering how today’s allergy forecast will affect your seasonal allergies? Are your seasonal allergies so bad that you always check the pollen count and allergy map before you head out?
The Zyrtec® AllergyCast® app helps take some of the guesswork out of managing your allergies. It uses advanced technology developed by Zyrtec allergy experts to predict how your allergy symptoms may make you feel so you can prepare for each day.

Personalized Predictions at Your Fingertips
When you first download the app, we’ll provide you with the pollen level in your area based on your zip code. Each day for 5 days, you’ll track your symptoms in the app.

After 5 days of tracking, we’ll unlock your personalized symptom predictions. This rating, on a scale from Low to Severe, lets you know how your allergy symptoms should really feel that day. The more you track, the smarter and more personalized our predictions become.

In addition to your daily symptom predictions, you’ll get a fresh-looking app that includes these features:
- Weather forecasts and insights for your zip code that updates based on your current location
- An enhanced allergy symptom tracker
- Allergy trends based on your tracked symptoms and treatments
- A list of the top allergens in your area
- A 3-day allergy symptom forecast
