Medical Studies Prove ORALAIR® Effectiveness
ORALAIR was studied in medical studies that included more than 2,500 adults and children with allergies to 1 or more of the 5 grass pollens in ORALAIR. Treatment was started about 4 months before the grass allergy season began and continued throughout the season.
- In medical studies, ORALAIR improved grass allergy symptoms in the first allergy season it was taken
- In another medical study, people who took ORALAIR before and during 3 grass allergy seasons in a row had their allergy symptoms improve even further in each year

Reduced Grass Allergy Symptoms
There are many symptoms of grass allergies, and some of the most common include:
- Sneezing
- Runny or itchy nose
- Nasal congestion
- Itchy and watery eyes
In medical studies, people reported that these symptoms were improved during the first grass pollen season they took ORALAIR. They also took less allergy medicines than people who did not take ORALAIR. Those allergy medicines included over-the-counter and prescription allergy medicines like antihistamines, nasal sprays, and other allergy pills.
In medical studies of ORALAIR*
The effectiveness of ORALAIR was measured in medical studies by a daily combined score of how troublesome allergy symptoms were and how much other allergy medicine was used.
*ORALAIR is approved for use in people 10 to 65 years old.
Continued Improvement, Season After Season
ORALAIR has also been proven to help beyond the first grass allergy season. A medical study showed that people who took ORALAIR about 4 months before and during 3 grass allergy seasons in a row had more symptom improvement and took less allergy medicine in each year. Your allergy specialist will be able to tell you when you should start taking ORALAIR before the next grass allergy season.
