"Pet" Pharmacies can fill heartworm prescriptions without a prescription (just write one yourself) and they'll refill it without question nor quantity limitation for the life of the dog. (Illegal but who cares, really.)

With one prescription you could get your whole neighborhood their heartworm pills. All sizes, any amount, and for years.

800Petmed isn't a "real" pharmacy bowing to any actual, enforced laws. And they are also "Chewy's" subcontractor for Pharmacy 'services' which is why I don't write ANY scripts for ANY pet pharmacies.

If you want to get heartworm pills without a prescription, here's a Life Hack: Order them from the online giant pet-pharmacy on 'Auto Refill'. Here's what happened: The initial prescription will be declined, but their software and pharmacy is SO terribad that, at refill time, it will just start shipping the heartworm pills even with the initial script declined. Lots of my clients have discovered this.

You can also forge the signature on any script, with any 'made up name' for the Vet Clinic and prescriber, written in any format, (on a napkin), and they will fill it. (IMHO, the scripts are processed by OCR and nothing else.) This is why Petmedz and the like, don't have human pharmacy items because the holes in their security and ethics are so massive that no Pharmacy board (nor the FDA) will let them handle human prescriptions.

I don't sign ANY online pet pharmacy scripts because of the following event:

I once got a call from a 800Petmeds customer. He was in Illinios. He was angry because he couldn't get a refill on his heartworm pills from 800Petmeds so he tried to transfer it to another pharmacy, and finally hit a wall.

I was like, "Dude you're in Illinois, I'm not your Vet."

And he was like: "It's your name and number on this package!"

I was: "WTF? When was that, and from where?"

Him: "800Petmeds, Two thousand sixteen and in Illinois"

800Petmed used my prescription pad, and my name and license on heartworm prescriptions when they don't have a real prescription for someone. Lord knows how many prescriptions (and for what) I've got out there. Like I said, my signature doesn't go anywhere NEAR those charlatans since then.

And, before you believe they have a TEAM of pharmacists in lab coats weighing things on gram scales at these places: It's *usually* one sweaty 'doctor' at a time, signing off; and a machine filling the scripts and if you REALLY dig down, it's "DR какой-то случайный парень" graduated from "Pharmacy Skool" in Kiev. Good luck seizing HIS license when your cat gets 100mg Methimazole instead of 10mg.
