Starting GRASTEKAlthough you may not be thinking about grass allergies or experiencing any grass allergy symptoms, the best time to start talking to your allergy specialist about GRASTEK is at least a few months before grass allergy season starts. Starting treatment early may give your body time to become less sensitive in preparation for the grass pollen season. Grass pollen season varies regionally.
