1. What is Grazax and what is it used for

Grazax contains a grass pollen allergen extract. Grazax is used for the treatment of rhinitis and conjunctivitis caused by grass pollen in adults and children (5 years or older). Grazax modifies the allergic disease by increasing immunological tolerance to grass pollen.

The selection of children to receive treatment should be made by doctors specializing in the treatment of allergic diseases in children.

Your doctor will assess your allergic symptoms and perform a skin diagnostic test or take a blood sample to decide if Grazax should be used as treatment.

It is recommended to take the first sublingual lyophilisate under medical supervision. This is a precaution to assess each patient's sensitivity to the treatment. This gives you the opportunity to discuss any possible side effects with your doctor.

Grazax is prescribed by doctors specializing in the treatment of allergies.
