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.

Tell your doctor about:
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.

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.
