What “equivalent” means here
This page uses the FDA therapeutic-equivalence designation only for matching strengths and labeled scheduled regimens. It does not establish cross-strength conversion, rescue use, SMART/MART dosing, or equivalence with other ICS/LABA products.
Inhaler counseling still matters
Both products are metered-dose inhalers, but patients should follow the product-specific instructions for priming, cleaning, dose tracking, and inhalation technique. Prescription and coverage questions still require a prescriber or pharmacist.
