1. What is Actair and what is it used for
This medication contains allergen extracts from house dust mites.
This medication is used to treat allergic rhinitis (inflammation of the nasal mucosa) in adolescents (12-17 years old) and adults. This medication 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.
Actair 100 IR is indicated only for the dose escalation period and not for maintenance.
Before starting treatment, a doctor must diagnose your allergy through skin tests and appropriate blood tests.
The first dose of this medication 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 monitor your sensitivity to the medication. It will also give you the opportunity to discuss any possible side effects with your doctor.
This medication should only be prescribed by a doctor with experience in treating allergies.
2. What you need to know before taking Actair
Do not take Actair
- If you are allergic to any of the excipients (other components) of this medication (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.

Do not start taking this medication if you are pregnant.
Warnings and precautions
Consult your doctor or pharmacist before starting to take this medication:
- If you experience 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 medication 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 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 medication until it has completely healed.

- 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.
