GRAZAX is a once daily sublingual (under the tongue) immunotherapy for hay fever available in a fast-melting tablet form.

GRAZAX tablets contain a tiny amount of grass pollen. Taken daily, this will help your immune system build up tolerance to grass pollen. In this case, GRAZAX treats the underlying cause of your allergy. This is called immunotherapy.

Over time, your immune system should react less and less and your hay fever symptoms should improve.

Are there any side effects?

Like many medicines there are some side effects which most people do not find troublesome.

The most common side effect of GRAZAX treatment is a tingling sensation under the tongue. This may happen directly after you have placed the tablet under the tongue. This effect is only temporary and usually does not last very long.

The following are rare but you must STOP the intake of GRAZAX and contact your doctor or hospital immediately if you experience any of the following symptoms:

  • Swelling of the face , mouth or throat
  • Difficulties in swallowing
  • Worsening of existing asthma
  • Rash
  • Difficulties in breathing
  • Voice changes

If GRAZAX has been prescribed for you do NOT pass it on to others, as it may harm them, even if their symptoms are the same as yours.
