What GRAZAX® is used for

GRAZAX® contains an allergen extract of grass pollen. It comes in a tablet form which is intended to be absorbed by the body by placing it under the tongue.

GRAZAX® is used to treat grass pollen allergies that are characterised by rhinitis (sneezing, runny or itchy nose, nasal congestion) and allergic conjunctivitis (itchy eyes) in adults and children 5 years or older.

GRAZAX® works by increasing your immunological tolerance to grass pollen, thereby reducing the severity of your allergic reactions over time.

Before starting treatment, the doctor will check if GRAZAX® is suitable for you by performing the appropriate blood and/or skin prick tests.

GRAZAX® is only available with a doctor’s prescription.

Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.

This medicine is not expected to affect your ability to drive a car or operate machinery.
