What brand names does oxybutynin ER go by?
Oxybutynin ER (extended-release) is sold under multiple brand names, depending on the manufacturer and the specific ER formulation in that country. Commonly searched brand names include:
- Ditropan XL
- Oxytrol (this is oxybutynin, but it is a different product form than ER tablets)
Because brand availability and naming can vary by country and over time, it helps to confirm which country you’re in and whether you mean ER tablets/capsules (not a patch).
Is Ditropan XL the main brand name for oxybutynin ER?
Ditropan XL is widely known as a brand name for oxybutynin extended-release tablets in the United States. Patients and clinicians often use “Ditropan XL” to refer specifically to oxybutynin ER tablet dosing schedules.
How can I tell if my prescription is oxybutynin ER?
Check the label for wording such as:
- “oxybutynin chloride ER”
- “extended-release”
- “ER tablets” (or “ER capsule” if applicable)
If it says “patch” (like Oxytrol), that’s oxybutynin but not ER tablets.
