The patent for Mybertriq is owned by the Japanese company Astellas Pharma Inc and is manufactured in Ireland and Japan. When last I tried to refill it at CVS the price was like $1400 with me contributing $400 for a 90 day supply of 25mg extended release so that is over $15/pill even if my cost is only $4.50 / pill. I live an hour south of Montreal and I have driven up there and refilled it for $300 without insurance.
Every Urologists I have seen is pushing the stuff and it is not worth the money even if someone else is paying. Classic example of the drug company bleeding patients for every penny they can.
Sorry for ranting.
