1. What is Actair and what is it used for

This medicine contains standardized allergen extracts from house dust mites.

This medicine is used to treat allergic rhinitis (inflammation of the nasal mucosa) in adolescents (12-17 years old) and adults. This medicine works by increasing immune tolerance to house dust mites (i.e., the body's ability to cope with their presence). You may not notice an improvement until you have been taking the treatment for 3 months.

Before starting treatment, a doctor must diagnose your allergy through skin tests or appropriate blood tests.

The first dose of this medicine should be taken under medical supervision. You should remain under medical observation for at least half an hour after taking the tablet. This is a precaution to observe your sensitivity to the medicine. It will also give you the opportunity to discuss any possible side effects with your doctor.

This medicine must be prescribed by a doctor with experience in the treatment of allergies.

2. What you need to know before you take Actair

Do not take Actair

  • If you are allergic to any of the excipients (other components) of this medicine (listed in section 6).
  • If you have severe and/or unstable asthma or have had a severe asthma exacerbation in the last 3 months.
  • If your doctor determines that your forced expiratory volume in one second [FEV1] is less than 80%.
  • If you have a disease that affects the immune system, if you are taking immunosuppressive medications, or if you have cancer.
  • If you have ulcers or oral infections. Your doctor will recommend delaying the start of treatment or interrupting it until your mouth is healed.

Do not start taking this medicine if you are pregnant.

Warnings and precautions

Consult your doctor or pharmacist before starting to take this medicine:

  • If you have severe allergic symptoms, such as difficulty swallowing or breathing, changes in voice, hypotension (low blood pressure), or feel a lump in the throat. Stop treatment and contact your doctor immediately.
  • If you have had a severe allergic reaction to a medicine with allergen extracts in the past.
  • If your asthma symptoms worsen more than usual. Stop treatment and contact your doctor immediately.
  • If you have a cardiovascular disease.
  • If you are taking a beta-blocker (a class of medications usually prescribed to treat heart diseases and high blood pressure and which is also present in some eye drops and ointments).
  • If you are receiving treatment for depression with tricyclic antidepressants or monoamine oxidase inhibitors (MAOIs) or for Parkinson's disease with catechol-O-methyltransferase (COMT) inhibitors.
  • If you are going to undergo oral surgery or a dental extraction, temporarily interrupt treatment with this medicine until it has completely healed.
  • If you have heartburn or difficulty swallowing. In that case, contact your doctor.
  • If you have an autoimmune disease in remission.

Tell your doctor:

  • About any disease you have had recently;
  • About your personal or family history of any disease that affects the immune system;
  • If your allergic disease has worsened recently.

Do not stop taking your asthma control and/or relief medications without your doctor's advice, as this may worsen your asthma symptoms.

During treatment, it is expected that some localized allergic reactions of mild or moderate intensity will occur. If the reactions are severe, talk to your doctor to determine if you need any antiallergic medication, such as antihistamines.
