This medication contains allergenic extracts of house dust mites.

This medication is used to treat allergic rhinitis (inflammation of the nasal mucosa) in adolescents (12-17 years) and adults. This medication works by increasing immunological 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 taken the treatment for 3 months.

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

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 observe your sensitivity to the medication. It will also give you the opportunity to discuss any possible adverse effects with your doctor.

This medication should be prescribed by a doctor with experience in treating allergies.

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 your immune system, if you are taking immunosuppressive medications, or if you have cancer.
• If you have mouth ulcers or oral infections. Your doctor will recommend delaying the start of treatment or interrupting it until your mouth has healed.

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 have severe allergic symptoms, such as difficulty swallowing or breathing, voice changes, low blood pressure, or a lump in your throat. Stop treatment and contact your doctor immediately.
• If you have had a severe allergic reaction to a medication with allergenic 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 often prescribed for heart disease and high blood pressure, and also present in some eye drops and creams).
• If you are receiving treatment for depression with tricyclic antidepressants or monoamine oxidase inhibitors (MAOIs) or for Parkinson's disease with catechol-O-methyltransferase inhibitors (COMTIs).
• If you are undergoing oral surgery or tooth extraction, interrupt treatment with this medication until you have fully healed.

Inform your doctor:

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

Do not interrupt the use of asthma control and/or relief medications without consulting your doctor, as it may worsen asthma symptoms.

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