Like all medicines, GRAZAX® can cause side effects, although not everybody gets them. The side effects may be an allergic response to the allergen you are being treated with. In most cases the side effects last from minutes to hours after taking the oral lyophilisate and settles down within one week of starting the treatment. Very common (affecting more than 1 in 10 people): Itching in the mouth and ears, irritation of the throat, sneezing and swelling in the mouth.
Please refer to the GRAZAX® Patient Information Leaflet (PIL) for more details.
