Was ProAir HFA discontinued in the FDA Orange Book?
The FDA Orange Book tracks approved drug products and gives information on patents and exclusivity, but it does not itself always clearly label a product as “discontinued” the way a manufacturer press release might. To verify whether ProAir HFA is discontinued (and, if so, when and which strengths are affected), you typically need to check the Orange Book listing for “ProAir HFA” and look for changes in the listed approved product (for example, deletion/sunset of a specific strength/labeler entry).
How to check the Orange Book for “ProAir HFA” accurately
On DrugProduct listing records, search by the trade name and/or the active ingredient: “albuterol sulfate” (the common active ingredient in ProAir HFA). Then confirm:
- Whether the Orange Book entry still shows an active marketing status for the relevant strengths
- Whether a particular labeler/strength appears to have been removed or replaced by a different listing
If you want, tell me the exact strength(s) you mean (for example, 8.5 g canister, 90 mcg per actuation) and I can help interpret what an Orange Book change usually signals.
Did Teva or another company replace ProAir HFA after discontinuation?
When a product is discontinued, the market often shifts to another authorized albuterol HFA product (same active ingredient and similar dosing), or to different albuterol formulations. Orange Book data can show whether another applicant’s HFA albuterol inhaler remains the active approved product at the same time.
To pinpoint replacements, you’d check Orange Book entries for:
- Other albuterol HFA products with the same strength
- Whether they carry the same or different NDA/BLA and labelers
What to do if your pharmacy can’t get ProAir HFA
If ProAir HFA is no longer being marketed in your area, patients are usually switched to an equivalent authorized albuterol inhaler (same active ingredient and commonly the same dosing). Any change should be guided by a clinician or pharmacist, especially for people with severe asthma/COPD who rely on fast rescue medication.
Patent/exclusivity angle: could listings change without “discontinuation”?
Orange Book entries can change because of:
- Patent status updates
- NDA/product labeling changes
- Applicant/labeler updates
- Consolidations of listings
Those changes are not always the same as “discontinued,” so it matters how the listing is updated.
If you’re trying to determine discontinuation specifically, the Orange Book should be treated as one evidence source, alongside manufacturer notices and pharmacy availability.

If you share the exact wording you see in the Orange Book (or a link/screenshot to the ProAir HFA entry) and the strength, I can help interpret whether the listing indicates discontinuation versus a record update.
