1. What is ORALAIR and what is it used for

ORALAIR contains an allergen extract. Treatment with ORALAIR is indicated to increase immunological tolerance to grass pollen and thereby reduce allergic symptoms.

ORALAIR is used for the treatment of grass pollen allergy, characterized by rhinitis (sneezing, runny nose, nasal itching, nasal congestion) with or without conjunctivitis (itchy eyes and tearing) in adults, adolescents, and children from 5 years of age.

Before starting treatment, the allergy must be diagnosed by means of skin tests or appropriate blood tests by a doctor specializing in the treatment of allergic diseases.

  • You are allergic to any of the other components of this medication (listed in section 6);
  • You have severe or unstable asthma or have suffered from severe asthma exacerbations in the last 3 months;
  • Your forced expiratory volume in one second (FEV1) is less than 80% as assessed by your doctor;
  • You have a disease that affects your immune system, are taking medications that suppress the immune system, or have cancer;
  • You have mouth ulcers or oral infections. Your doctor may recommend delaying the start of treatment or interrupting it until your mouth has healed.

Do not start taking ORALAIR if you are pregnant.

Warnings and precautions

Consult your doctor or pharmacist before starting to take ORALAIR if:

  • You experience severe allergic symptoms, such as difficulty swallowing or breathing, changes in your voice, hypotension (low blood pressure), or a sensation of a lump in the throat. Interrupt treatment and contact your doctor immediately.
  • You have previously had severe allergic reactions to a medication containing allergen extracts.
  • Your asthma symptoms worsen more than usual. Interrupt treatment and contact your doctor immediately.
  • You have a cardiovascular disease.
  • You are taking a beta-blocker (a class of medications commonly prescribed for heart conditions and high blood pressure, but also present in some eye drops and ointments).
  • You are being treated for depression with tricyclic antidepressants or monoamine oxidase inhibitors (MAOIs), or for Parkinson's disease with catechol-O-methyltransferase (COMT) inhibitors.
  • You need to undergo oral surgery or a dental extraction, you should interrupt treatment with ORALAIR until you are fully healed.
  • You persistently experience heartburn or difficulty swallowing. You should contact your doctor.
  • You have an autoimmune disease in remission.

Tell your doctor about:

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

If you take medications to control and/or relieve asthma, do not stop asthma treatment without your doctor's advice, as this may worsen asthma symptoms. If you have asthma and a respiratory infection, you should postpone the start of treatment with ORALAIR until the infection has resolved.

You may expect some localized allergic reactions, from mild to moderate, during treatment. If these reactions are severe, talk to your doctor to see if you need any anti-allergic medication such as antihistamines.

Children and adolescents

ORALAIR is used for the treatment of grass pollen allergy with or without conjunctivitis in adolescents and children from 5 years of age. ORALAIR is not indicated for use in children under 5 years of age.

Other medications and ORALAIR

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medications, including those without a prescription.

Especially inform your doctor if you are taking certain antidepressants (tricyclic antidepressants and monoamine oxidase inhibitors (MAOIs).

If you are taking other medications for allergies, such as antihistamines, medications for asthma relief, or steroids, or medications that block a substance called immunoglobulin E (IgE), such as omalizumab, talk to your doctor if you should continue taking them. If you stop taking those allergy medications, you may experience more side effects during treatment with ORALAIR. Symptomatic treatment (e.g., antihistamines and/or nasal corticosteroids) can be used along with ORALAIR.

Consult your doctor or pharmacist before taking Oralair: if you are taking a beta-blocker (i.e., a type of medication commonly prescribed for heart disorders and high blood pressure, and also present in some eye drops and ointments), as this medication may reduce the effectiveness of adrenaline used to treat severe systemic reactions.
