Quackgrass Pollen Extract for Grass-Pollen Allergy
Quackgrass pollen extract is a prescription allergen extract that contains the pollen proteins responsible for some grass-pollen allergies. It is used as immunotherapy to gradually reduce symptoms such as sneezing, congestion, runny nose, and itchy nose caused by grass pollen.
This treatment may help reduce grass-pollen allergy symptoms over time, but it is not immediate relief. It should be used only according to an allergist’s instructions, and emergency help is needed for signs of a severe allergic reaction.
