Try mdcustomrx.com

You can get transdermal (skin absorption) applications, too. Looks like they can do this with a wide range of meds.

You do need a prescription though

I have some makers in my small-ish town, too. My vet says if one doesn't have it, most likely the other guy does.

She mentioned Walgreens as a supplier too.

I don't know about that option as I was unaware.

Good luck!
