Diagnosing Asthma

How Will Your Doctor Diagnose Asthma?

Get to Know the Facts

Describe your symptoms

It's important to explain what your asthma symptoms are ("wheezy feeling in my chest"€) as well as how these symptoms make you feel ("€œI just can't catch my breath"). Your doctor will also want to know when and where your asthma symptoms occur most. Do they happen during a certain time of day? Do they happen in any particular room?

Know your family history

Tell your doctor about your family members. Does anyone else have asthma? Allergies? Eczema (red, swollen, and itchy skin)? A family history of these conditions can mean an increased risk for asthma.

Physical exam

Your doctor will look for swollen nasal passages and listen to your breathing — paying special attention to sounds of asthma, like wheezing or coughing. Keep your appointment, even if you don't have symptoms on the day of your doctor visit, because your doctor can still listen to your lungs and examine your nasal passages.

Other Tests

Your doctor may order other tests if he or she needs more information to make an asthma diagnosis.

Important Safety Information

PULMICORT FLEXHALER is not a bronchodilator and should NOT be used to treat an acute asthma attack. If you are switching to PULMICORT FLEXHALER from an oral corticosteroid, follow your doctor's instructions to avoid serious health risks when you stop using oral corticosteroids.

Avoid exposure to infections such as chicken pox and measles. Tell your doctor immediately if exposed. Inhaled corticosteroids may cause a reduction in growth rate. The long-term effect on final adult height is unknown.

Rare instances of glaucoma, increased intraocular pressure, cataracts have been reported following the inhaled administration of corticosteroids.

PULMICORT FLEXHALER contains small amounts of lactose, which contains trace levels of milk proteins. In patients who have severe milk protein allergy (not those who are lactose intolerant) cough, wheezing, or bronchospasm may occur.

Be sure to tell your healthcare provider about all your health conditions, and all medicines you may be taking.

As with other inhaled asthma medications, bronchospasm, with an immediate increase in wheezing, may occur after dosing. If bronchospasm occurs following dosing with PULMICORT FLEXHALER, it should be treated immediately with a fast-acting inhaled bronchodilator. Treatment with PULMICORT FLEXHALER should be discontinued and alternate therapy instituted.

The most commonly reported side effects in clinical trials include inflammation of the nose and throat, nasal congestion, sore throat, nasal allergies, viral upper respiratory tract infection, and thrush in the mouth and throat.

Approved Use

PULMICORT FLEXHALER (budesonide inhalation powder, 90 mcg & 180 mcg), an inhaled corticosteroid, is used for the maintenance treatment of asthma in adults and children 6 years or older.
