What does the FDA Orange Book say about Pexeva (paroxetine mesylate) if it was discontinued?
The FDA’s Orange Book is where the FDA lists approved drugs and the “patent/exclusivity” information tied to those approvals. If a product is shown as discontinued, it generally means the manufacturer has stopped marketing that specific listed drug product (for the listed dosage form/strength), even though the drug may still have other approved versions or other manufacturers’ products.
To confirm the current status for Pexeva (paroxetine mesylate), you would check the Orange Book listing for the exact proprietary name (Pexeva) and the specific dosage form/strength, because discontinuation can apply to one NDC/product entry rather than to paroxetine mesylate as a whole.
How to check the Orange Book entry for Pexeva specifically
On the Orange Book site, look up:
- Active ingredient: paroxetine mesylate
- Proprietary name: Pexeva
- Then verify whether the product entry is marked as “Discontinued” (or whether the NDC is no longer listed as active)
If Pexeva is discontinued, it may still be possible to find other paroxetine formulations (including other brands or generics) that remain listed as active in the Orange Book under different product/NDC entries.
Is Pexeva discontinued only in marketing, or can the approval still be active?
Orange Book “discontinued” language usually relates to the marketed drug product status (marketing/NDC activity) rather than automatically removing the original FDA approval record. That’s why you may still see an approved listing or patent/exclusivity data even after the product is no longer sold, depending on how the Orange Book record is maintained.
Could generic paroxetine still be available even if Pexeva is discontinued?
Often yes. If Pexeva (brand) is discontinued, generic paroxetine products may still be marketed and listed in the Orange Book under their own NDCs. Clinicians typically switch patients from a discontinued brand to an available equivalent product if one exists for the same active ingredient, route, and dose.

What to do if you’re trying to switch from Pexeva
If your goal is to replace a discontinued Pexeva product, you’d typically verify:
- the exact strength and formulation you were taking,
- whether an equivalent paroxetine mesylate product (same route and dosing) is available,
- and any need for prescriber-directed dose conversion if the formulation differs.
If you tell me the Pexeva strength you used (for example, tablet amount) and the dosage form, I can guide you on what to look up in the Orange Book for the closest active equivalent listing.
