ORALAIR is a sublingual (under the tongue) grass allergy immunotherapy tablet used to treat symptoms of allergies to the grass pollens in ORALAIR. It is an allergy immunotherapy, which means that it works differently than other medicines you may take when you experience bothersome allergy symptoms.

When to Start ORALAIR Treatment

  • It is important to know that ORALAIR is a grass allergy treatment you start taking about 4 months before the grass allergy season begins. It is not a medication that gives immediate relief of allergy symptoms. This means you may begin taking ORALAIR when you aren’t likely having any symptoms of your grass allergy. You continue taking it every day throughout the grass allergy season, until your allergy specialist tells you to stop.

ORALAIR can cause severe allergic reactions that may be life-threatening. Symptoms of allergic reactions to ORALAIR include:

  • Trouble breathing
  • Throat tightness or swelling
  • Trouble swallowing or speaking
  • Dizziness or fainting
  • Rapid or weak heartbeat
  • Severe stomach cramps or pain, vomiting, or diarrhea
  • Severe flushing or itching of the skin

If any of these symptoms occur, stop taking ORALAIR and immediately seek medical care. For home administration of ORALAIR, your doctor should prescribe auto-injectable epinephrine for you to keep at home for treating a severe reaction, should one occur. Your doctor will train and instruct you on the proper use of auto-injectable epinephrine.

Please see additional Important Safety Information below and full Prescribing Information, including Boxed Warning and Medication Guide.

How it works:

  • Treatment with Oralair is intended to increase the immunological tolerance towards grass pollens, thereby building immunity to the specific allergens in grass pollens, thus helping to reduce the allergic symptoms.
  • Ask your doctor if you have any questions why Oralair has been prescribed for you.
  • Oralair is not addictive.
  • This medicine is available only with a doctor’s prescription.

Before you are given Oralair

Do not take Oralair:

  • if you are hypersensitive (allergic) to any of the other ingredients of Oralair;
  • if you suffer from severe and/or unstable asthma;
  • if your immune system is very weakened or if you suffer from a disease that attacks your own immune system;
  • if you suffer from a malignant disease (for example cancer);
  • if you have any inflammation in your mouth (for example mouth ulcers, bleeding gums).
  • If you are not sure if you should be taking Oralair, talk to your doctor.

Before you start your treatment with Oralair:

Take special care with Oralair:

  • If you have to undergo surgery in the mouth or if you are having a tooth pulled, you should stop treatment with Oralair for 7 days to allow your oral cavity to heal. Thereafter, restart treatment with the previous dosage. If you stopped treatment for more than 7 days, please ask your doctor how you should restart treatment.

Talk to your doctor if:

  • you have any history of allergic inflammation of the oesophagus (eosinophilic oesophagitis). During treatment with Oralair, if you have severe or persistent upper abdominal pain, swallowing difficulties or chest pain, please contact your doctor who may reconsider your treatment.
  • you are taking a beta blocker (i.e., a class of drugs often prescribed for heart conditions and high blood pressure but also present in some eye drops and ointments), as this drug may decrease the effectiveness of adrenaline, a medicine used to treat serious allergic reactions.

Tell your doctor if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

Pregnancy and breast-feeding

  • Ask your doctor for advice before taking any medicine.
  • At present there is no experience for the use of Oralair during pregnancy. Therefore, you should not start immunotherapy if you are pregnant. If you become pregnant, speak to your doctor about whether it is appropriate for you to continue treatment.
  • There is no experience for the use of Oralair during breast-feeding as well. No effects on infants who are breast-fed during treatment are anticipated. However, you should not start immunotherapy if you are breast-feeding. If you wish to breastfeed while on treatment, speak to your doctor about whether it is appropriate for you to continue treatment.

Driving and using machines

  • No effect on the capacity to drive or use machines has been observed with Oralair.

Important information about some of the ingredients of Oralair

  • This medicine contains lactose. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.
  • Your doctor will advise you.
  • Your doctor has more information on medicines to be careful with or avoid while taking Oralair.

How Oralair is given

Treatment should be started 4 months before the onset of the pollen season.

Always take Oralair exactly as your doctor has told you. Check with your doctor if you are not sure.

Oralair is prescribed by doctors with adequate training and experience in treatment of allergy. With prescriptions for children, the doctor will have the relevant experience in the treatment of children.

You are advised to take the first tablet under medical supervision and be monitored for 30 minutes. This gives you the opportunity to discuss possible side effects with your doctor.


  • Adults, adolescents and children above the age of 5
  • The therapy is composed of an initiation treatment (first month of treatment, including a 3-day dose escalation) and a continuation treatment.

Initiation Treatment:

The pack corresponding to the initiation treatment (first month of treatment) contains two blisters:

  • One small blister with 3 tablets of 100 IR
  • One large blister with 28 tablets of 300 IR

Method of administration

Take one 100 IR tablet on day one. Keep the tablet under your tongue until it is completely dissolved (for at least 2 minutes) before you swallow. On the second day, two 100 IR tablets are put under the tongue simultaneously and then swallowed after about 2 minutes. It is recommended that the tablets be taken during the day.

Continuation Treatment:

The package corresponding to the continuation treatment (from the second treatment month) contains larger blisters packs with 30, 90, or 100 tablets of 300IR sublingual tablets

From the 2nd month onwards, treatment must be continued until the end of the pollen season with 1 tablet of 300 IR once a day from the Oralair CONTINUATION TREATMENT which contains 300 IR sublingual tablets only.

Duration of treatment

  • Take these tablets as prescribed by your doctor. Start treatment about 4 months before the beginning of the pollen season and continue it until the end of the pollen season.
  • Treatment is to be repeated over 3 consecutive grass pollen seasons.
  • If necessary, your doctor may, at the same time, prescribe medication to treat the possible allergic symptoms.

There is no experience with Oralair in young children (younger than 5 years) and in patients over 65 years of age.

How long should Oralair be taken for?

Oralair is started 4 months before the pollen season and then continued until the pollen season ends. Each year your Doctor will assess if it is suitable for you to restart Oralair treatment. Results from a recent long term study have shown that patients treated over 3 consecutive pollen seasons with Oralair, did not require further treatment in the 4th year.

If you take more Oralair than you should

If you take more Oralair than you should, you may experience allergic symptoms including local symptoms from mouth and throat. If you experience severe symptoms, such as angioedema (i.e. swelling), difficulty in swallowing, difficulty in breathing, changes in voice, or a feeling of fullness in the throat, seek urgent medical advice.

If you forget to take Oralair

  • Do not take a double dose to make up for a forgotten dose.
  • If you interrupted treatment with Oralair for less than one week, you can take up treatment where you left off.

If you stop taking Oralair

  • If you stop taking Oralair before the full treatment end, you may not have an effect from the treatment.
  • If you have any further questions on the use of this product, ask your doctor.

While you are receiving Oralair
