Typical dosage for Grastek

The typical dose is 1 Grastek tablet dissolved under the tongue once a day. Each tablet contains 2,800 bioequivalent allergy units (BAU).

You need to take your first dose at a medical office so that you're supervised by a healthcare professional. They have to make sure that the medication is safe for you before you can start taking it at home.

You usually start taking Grastek at least 3 months before allergy season and keep taking it during the season.

For lasting effects, you can also take Grastek every day for 3 years in a row (including between seasons). After you finish the 3-year treatment, the effects of the medication can last for another year.
