Lol. Never! And last year, I figured I'd filled right at 1,000,000 prescriptions over the years. I've never even seen it in a pharmacy and I've worked in about 50 different pharmacies. I hate to burst your bubble, but it's not common and my responses were accurate. I challenge you to call 5 pharmacies and ask the pharmacist if he's even heard of the drug. If he says yes, ask him the mechanism of action. That should be fun.
