Why does my cancer medicine make me urinate more?

Dear Erwin — Yes, me too. I pee and 10 minutes later I feel I have to pee again. My urologist prescribed mirabegron. For me, it’s been slightly effective at best, and it’s expensive. (I use Good Rx coupons; cheaper than using my Medicare Part D insurance coverage). But look into it; you may want to give it a try.

Thank you

Erwin, here’s a followup on my posting above. I’ve terminated my mirabegron. It was benefitting me—if at all—so minimally that it isn’t worth the time, cost, and trouble of getting it. I’ve been forced to admit that I have vesical and rectal tenesmus (you should look it up) and I probably always will, owing to being almost 78 years old and recognizing that age is a huge factor in odds there will ever be recovery. Here’s hoping that you, Erwin, are considerably less than 78!

Thank you Dave
