RAGWITEK is ragweed allergy immunotherapy in a tablet

RAGWITEK® (Short Ragweed Pollen Allergen Extract) Tablet (not actual size)

Instead of a shot, RAGWITEK is a once-a-day tablet that dissolves quickly when placed under the tongue. After taking it, do not swallow for at least 1 minute. RAGWITEK is made from small amounts of natural short ragweed pollen and may help you gradually build tolerance so you become less sensitive to ragweed pollen.

RAGWITEK® (Short Ragweed Pollen Allergen Extract) is a daily dose of immunotherapy

Immunotherapy is designed to repeatedly expose your body to small amounts of an allergen. That’s why it’s important to take RAGWITEK every day, as your allergy specialist prescribes, even when you don’t have symptoms.

Taking the first tablet in your allergy specialist’s office

The first dose of RAGWITEK must be taken in the allergy specialist’s office. After taking the first dose, you will be observed for at least 30 minutes by a health care professional for symptoms of a serious allergic reaction. If the first dose is well tolerated, you can continue to take your RAGWITEK once a day at home.
