Pulmicort Alternatives and FDA-Approved Generic Budesonide
FDA determined Budesonide Inhalation Suspension 0.25 mg/2 mL and 0.5 mg/2 mL to be bioequivalent and therapeutically equivalent to matching Pulmicort Respules strengths. The Pulmicort Respules 1 mg/2 mL strength is not included as a direct equivalent on this page.
Direct equivalent
Matching Pulmicort Respules and generic budesonide strengths
FDA determined generic budesonide inhalation suspension to be bioequivalent and therapeutically equivalent at the two matching strengths below. The Pulmicort Respules 1 mg/2 mL strength is not presented as a direct equivalent.
Pulmicort
0.25 mg/2 mL — 1 single-dose ampule by jet nebulizer twice daily
Budesonide Inhalation Suspension
0.25 mg/2 mL — 1 single-dose ampule by jet nebulizer twice daily
Pulmicort
0.5 mg/2 mL — 1 single-dose ampule by jet nebulizer twice daily
Budesonide Inhalation Suspension
0.5 mg/2 mL — 1 single-dose ampule by jet nebulizer twice daily
What “equivalent” means here
The FDA designation applies only to matching 0.25 mg/2 mL and 0.5 mg/2 mL inhalation suspensions. It does not establish equivalence for the brand-only 1 mg/2 mL strength or for another budesonide formulation or device.
Pediatric nebulizer counseling matters
These suspensions are labeled for maintenance therapy in children 12 months to 8 years—not rapid symptom relief. Use a compressed-air jet nebulizer, not an ultrasonic device, and rinse the mouth after treatment.
Common questions
Pulmicort Respules and generic budesonide FAQ
Does Pulmicort Respules have an FDA-approved generic?
Yes. FDA approved Budesonide Inhalation Suspension 0.25 mg/2 mL and 0.5 mg/2 mL under ANDA 78-202 as generic versions of matching Pulmicort Respules strengths.
Which Pulmicort Respules and generic budesonide strengths match?
The FDA-supported matching strengths on this page are 0.25 mg/2 mL and 0.5 mg/2 mL. Each is an inhalation suspension supplied in a single-dose ampule for jet-nebulizer administration.
Is Pulmicort Respules 1 mg/2 mL included as a direct generic equivalent?
No. Pulmicort Respules labeling includes a 1 mg/2 mL strength, but the FDA ANDA evidence used for this page identifies generic 0.25 mg/2 mL and 0.5 mg/2 mL products. The 1 mg/2 mL strength is therefore not displayed as a direct equivalent here.
What is the labeled age range for nebulized budesonide asthma maintenance?
Pulmicort Respules and generic budesonide inhalation suspension are labeled for asthma maintenance treatment and prophylactic therapy in children 12 months to 8 years of age. The prescribed dose depends on previous therapy and asthma control.
Can Pulmicort Respules or generic budesonide treat sudden asthma symptoms?
No. Budesonide inhalation suspension is an inhaled corticosteroid for maintenance therapy, not a rapid-relief bronchodilator. It should be administered with a compressed-air jet nebulizer rather than an ultrasonic nebulizer, and the mouth should be rinsed after treatment.
