Medically reviewed by Last updated on Sep 4, 2023.

PULMICORT FLEXHALER should be administered twice daily by the orally inhaled route only. After inhalation, the patient should rinse the mouth with water without swallowing [see Patient Counseling Information (17.1)].

Patients should be instructed to prime PULMICORT FLEXHALER prior to its initial use, and instructed to inhale deeply and forcefully each time the device is used.

The safety and efficacy of PULMICORT FLEXHALER when administered in excess of recommended doses have not been established.

After asthma stability has been achieved, it is desirable to titrate to the lowest effective dosage to reduce the possibility of side effects. For patients who do not respond adequately to the starting dose after 1-2 weeks of therapy with PULMICORT FLEXHALER, increasing the dose may provide additional asthma control.


If asthma symptoms arise in the period between doses, an inhaled, short-acting beta2-agonist should be taken for immediate relief.

Patients 18 Years of Age and Older: For patients 18 years of age and older, the recommended starting dosage is 360 mcg twice daily. In some adult patients, a starting dose of 180 mcg twice daily may be adequate. The maximum dosage should not exceed 720 mcg twice daily.

Patients 6 to 17 Years of Age: The recommended starting dosage is 180 mcg twice daily. In some pediatric patients, a starting dose of 360 mcg twice daily may be appropriate. The maximum dosage should not exceed 360 mcg twice daily.

For all patients, it is desirable to titrate to the lowest effective dose after adequate asthma stability is achieved.

Improvement in asthma control following inhaled administration of budesonide can occur within 24 hours of initiation of treatment, although maximum benefit may not be achieved for 1 to 2 weeks, or longer. Individual patients will experience a variable onset and degree of symptom relief.

If a previously effective dosage regimen of PULMICORT FLEXHALER fails to provide adequate control of asthma, the therapeutic regimen should be re-evaluated and additional therapeutic options (e.g., replacing the lower strength of PULMICORT FLEXHALER with the higher strength or initiating oral corticosteroids) should be considered.
