grass pollen allergen extract
How does this medication work? What will it do for me?
Grass pollen allergenic extract belongs to the class of medications called allergy immunotherapies. It is used to decrease the symptoms of moderate-to-severe seasonal allergies to grass pollens, when other allergy treatments have not been effective. Before treatment with grass pollen allergenic extract, your doctor will confirm your allergy with either a skin or a blood test.
This medication works by causing the body’s immune system to become less sensitive to the effects of the pollen. It may be started at any point during the year, but for symptoms to improve during the first allergy season, it should be started 4 months before the grass pollen season begins.
