How our ALLERGYCAST® Predictions work
Wondering how your day may be affected by your allergy symptoms? Knowing local pollen levels can help, but many allergy sufferers need more than just a pollen count to plan their day.
The Zyrtec® AllergyCast® app goes beyond pollen levels alone. Our personalized symptom severity prediction technology calculates how the local pollen levels in the air may make you feel - giving you your very own personalized symptom severity prediction. It's like a "real-feel" forecast for your allergies!
When you start using the app, you’ll receive pollen levels and a generalized symptom severity prediction based on data including local pollen levels, weather conditions, and air quality. To unlock personalized symptom severity predictions, simply sign in and track your symptoms. The more consistently you log, the more personalized your symptom severity predictions will become.
After you've started tracking symptoms, you'll get a daily symptom severity prediction, as well as a forecast for the next several days! It's calculated using unique-to-you factors like your tracked symptoms and the local weather, with some help from Zyrtec®'s allergy experts.
Did AllergyCast® predict a "Mild" symptom day? Great! You can expect less sniffling and sneezing.
Are "Severe" symptoms predicted? You may want to have some tissues handy or plan to spend less time outside that day.
