Many (if not all) flea meds are available over the counter. It is the heartworm meds which require a prescription. This one, Advantage Multi, includes a heart worm component.

Federal (U.S.A.) law restricts this drug to use by or on the order of a licensed veterinarian.

You will see this on any reputable site offering it. I would never get a script med without a script, not for me, not for my pets. How do you know it is not counterfeit? It may not be "real," and hence not effective. That would worry me.

Drs Foster and Smith, and 1-800 Pet Meds are both reputable, and have Vet-VIPPs certification.
