Effexor xr patent expiration date?

Do you mean the patent expiration date for Effexor XR in the US, and do you want the date for the active ingredient (venlafaxine) patent or for the extended-release formulation (XR) patent? Patent protection can involve multiple patents (composition, formulation, method of use) and different dates by country.

If you’d like, I can help you find the exact dates. Here’s how you can check it quickly:

- In the US, use the FDA Orange Book (Patents and Exclusivity) or Google Patents.
- Search for “venlafaxine” or “Effexor XR.”
- Look for the entries under “Patents” or “Exclusivities” to see the expiration dates for each patent/family.
- Note the country: patent expiry can differ outside the US, and there may be pediatric exclusivities or settlement-related extensions.

If you can share whether you want US data or another country, and specify whether you want the active ingredient patent vs. the XR formulation patent, I’ll tailor the answer and help interpret the exact dates.
