FDA OKs Merck Tablet to Reduce Ragweed Allergies

Posted: Updated:

U.S. regulators have again approved a Merck & Co. tablet for gradually reducing seasonal allergies, this time for ragweed pollen.
 
Ragwitek tablets dissolve quickly under the tongue. Patients are to take one daily for a few years, starting  three months before ragweed season begins in late summer. The Food and Drug Administration approved it for patients aged 18 through 65.
 
Whitehouse Station, N.J.-based Merck's tablet for spring grass allergies, Grastek, was approved Monday for patients aged 5 to 65. 
 
Both offer an alternative to medicines that just temporarily relieve symptoms or years of uncomfortable allergy shots.
 
The shots and tablets work by gradually tamping down immune response to allergy-triggering substances and reducing sneezing, runny noses and itchy, watery eyes.
 
Ragwitek and Grastek should be available in pharmacies by April 30. (AP)
