What the FDA labels say
From the Budesonide (PULMICORT FLEXHALER) label · effective 2026-01-29
Patients should be instructed to contact their physician immediately if episodes of asthma not responsive to their usual doses of bronchodilators occur during the course of treatment with PULMICORT FLEXHALER.
Deterioration of Asthma or Acute Episodes PULMICORT FLEXHALER is not a bronchodilator and is not indicated for the rapid relief of bronchospasm or other acute episodes of asthma.
If paradoxical bronchospasm occurs following dosing with PULMICORT FLEXHALER, it should be treated immediately with an inhaled, short-acting beta 2 -bronchodilator.
From the Theophylline label · effective 2026-01-29
Dosage Increases: Increases in the dose of theophylline should not be made in response to an acute exacerbation of symptoms of chronic lung disease since theophylline provides little added benefit to inhaled beta2 -selective agonists and systemically administered corticosteroids in this circumstance and increases the risk of adverse effects.
