Brief Answer:
Possibly losartan

Detailed Answer:
Hello, I'm Dr. Branch, thanks for using Ask a Doctor. The only pills I could find that might match your description would be Losartan, which are green, have 46 on one side, and E on the other (which may look like a 3?). I do not see any Xanax pills that would be similar to this.

Losartan is commonly used as a blood pressure medication.

If you would like to send a picture of the pill, I might be able to confirm for sure what it is.

I hope that helps, please let me know if you have any questions about any of that, and I would be glad to discuss it with you further.
