What is in this leaflet

This leaflet answers some common questions about Oralair Initiation Treatment and Oralair Continuation Treatment sublingual tablets.

It does not contain all the available information.

It does not take the place of talking to your doctor.

All medicines have risks and benefits. Your doctor has weighed the risks of you taking Oralair against the expected benefits it will have for you.

If you have any concerns about taking this medicine, ask your doctor.

What is Oralair used for

Oralair contains an allergen extract. Treatment with Oralair is intended to increase the immunological tolerance towards certain grass pollens, thereby reducing the allergic symptoms.

Oralair is used for the treatment of certain grass pollen allergies that are characterised by rhinitis (sneezing, runny or itchy nose, nasal congestion) with or without conjunctivitis (itchy and watery eyes) in adults, adolescents and children above the age of 5.

Before treatment, the allergy is confirmed by a doctor with adequate training and experience in allergic diseases, who will perform the appropriate skin and/or blood tests.

The grass pollens that Oralair is used for are: Dactylis glomerata (cocksfoot); Lolium perenne (rye grass); Anthoxanthum odoratum (sweet vernal grass); Phleum pratense (timothy) and Poa pratensis (meadow grass).

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;
  • You suffer from severe and/or unstable asthma or experienced severe asthma exacerbation within the last 3 months;
  • Your forced expiratory volume in one second (FEV1) is below 70% as assessed by your doctor;
  • You have an illness which affects the immune system, you are taking medicines which suppress the immune system or if you have cancer;
  • You have mouth ulcers or mouth infections. Your doctor may recommend delaying the start of the treatment or stopping treatment until your mouth has healed.

Do not start taking ORALAIR if you are pregnant.

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:

Talk to your doctor before taking ORALAIR if:

  • You experience severe allergic symptoms, such as difficulty in swallowing or breathing, changes in your voice, hypotension (low blood pressure) or a feeling of a lump in the throat. Stop the treatment and contact your doctor immediately or go to the Emergency Department at your nearest hospital
  • You have previously had a severe allergic reaction to a drug with allergen extracts.
  • Your asthma symptoms get noticeably worse than normal. Stop treatment and contact your doctor immediately.
  • You have a cardiovascular disease.
  • 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.
  • You are taking MAOIs, tricyclic antidepressants and COMT inhibitors. Allergen immunotherapy in patients treated with mono amine oxidase inhibitors (MAOIs) or tricyclic antidepressants or for Parkinson’s disease with COMT inhibitors should be considered carefully as these treatments could potentiate the effect of adrenaline (epinephrine).
  • You need mouth surgery or a tooth extraction, you should temporarily stop treatment with ORALAIR until completely healed.
  • You have an autoimmune disease in remission
  • 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.

Talk to your doctor about:

  • Any recent disease you may have had,
  • Personal or family history of any disease which could affect your immune system,
  • If your allergic illness has recently worsened.

If you take asthma controller and/or reliever medications, do not interrupt your asthma treatment without your doctor’s advice as this may worsen the asthma symptoms.

You can expect some mild to moderate localised allergic reactions during your treatment. If those reactions are severe, talk to your doctor to see if you need any anti-allergic medicines such as antihistamines.

Taking other medicines

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

If you are taking other allergy medicines such as antihistamines, asthma relief medication or steroids or a medication that blocks a substance called immunoglobulin E (IgE) e.g., omalizumab, discuss with your doctor whether to continue taking them. Do not stop taking these medicines before talking to your doctor. If you stop taking those allergy medicines you may experience more side effects during ORALAIR treatment.

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. 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.

The first dose of Oralair should be taken under medical supervision. You should stay under medical observation for at least half an hour after taking the first dose. This is a precaution to monitor your sensitivity to the medicine. This gives you the opportunity to discuss possible side effects with your doctor.


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

Method of administration

Keep the tablet under your tongue until it completely dissolve (at least 2 minute) before you swallow it. On the second day, put two 100 IR tablets simultaneously under the tongue and then swallow after about 2 minutes. It is advisable to take the tablet during the day, in an empty mouth. Do not eat or drink for at least 5 minutes.

Initiation Treatment:

The treatment with ORALAIR should be initiated as follows:

Continuation Treatment:

The dose is 300 IR (one tablet) daily until the end of the pollen season.

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 Oralair should 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.
