Great Lakes
(Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, Ohio, Wisconsin)
In the Great Lakes region, trees with pollen that can trigger nasal allergy symptoms are elm, maple/box elder, alder, birch, oak, and hickory. They can pollinate from March through June. Oak trees may continue pollinating until mid-June.
Many grasses pollinate in this region during the summer, from May to July. Starting in May, redtop, brome, orchard grass, fescue, rye, Bermuda, and timothy pollinate.
Weeds generally pollinate from July to September, including ragweed, plantain, and nettle. Other weeds that are allergens or trigger nasal allergy symptoms include waterhemp, lamb's quarter, pigweed, Mexican fire bush, and Russian thistle. Later in the season, hemp can trigger symptoms for people with seasonal nasal allergies—typically from mid-July to mid-August. Then, from early August until late September, ragweed pollinates in this region.
Note: Trees, grasses, and weeds do not pollinate at the same time or in the same sequence each year.

Bothered by Seasonal Nasal Allergies?
Ask your doctor if NASONEX® may be able to treat or help prevent most of your seasonal nasal allergy symptoms.
For the treatment of seasonal and perennial nasal allergy symptoms...
NASONEX® is a prescription nasal allergy spray approved for the treatment of seasonal and perennial nasal allergy symptoms in adults and children 2 years of age and older. Taken just once a day as directed by your doctor, NASONEX® helps relieve nasal allergy symptoms. These symptoms are itchy nose, runny nose, sneezing and congestion. NASONEX® helps by treating nasal allergy symptoms caused by dust mites, pet dander, even tree and grass pollen. Improvement can occur within 11 hours of initial treatment (based on studies done in a park during the pollen season and in a controlled pollen exposure room). The maximum benefit of NASONEX® is usually achieved within 1 to 2 weeks.
To help prevent most seasonal nasal allergy symptoms...
NASONEX® is the only prescription nasal spray clinically proven and FDA-approved to help prevent most seasonal nasal allergy symptoms in adults and children 12 years and older in addition to treating them once they occur. To help prevent most seasonal nasal allergy symptoms before they start, begin treatment 2 to 4 weeks before the anticipated start of the pollen season. It is important that you take NASONEX® regularly at the time recommended by your doctor, since its effectiveness depends on regular use.
And treatment of nasal polyps...
NASONEX® is proven effective to treat nasal polyps in patients 18 years and older.
