Are you a real, licensed pharmacy?

Yes. We are a licensed, veterinarian-staffed pharmacy. A licensed veterinarian reviews every prescription and a licensed pharmacy dispenses it.

Do I need a prescription from my own vet?

Not necessarily. If you have one you can attach it. If you do not, our licensed veterinarian can review your request and write the prescription at no separate cost; you pay only for the medication.

How does ordering work?

You reserve the medication with no payment. A licensed vet reviews it, usually within one business day. You get one email with your prescription and a secure payment link. Once you pay it ships with tracking.

Is it safe to give my pet antibiotics from an online pharmacy?

It is safe when a licensed vet has reviewed it for your specific animal, which is our process. We never sell prescription medication without that review.

Where do you ship and what does it cost?

We ship nationwide across the United States with free shipping. International orders are handled case by case.

Vet-prescribed medication

Medically reviewed by Dr. Olivier Toulza September 3, 2026

Information only — not currently available to order from PrepperPetSupply. Need help getting it?

Fluoxetine for Dogs & Cats is a vet-prescribed medication for separation anxiety. Fluoxetine is a prescription SSRI (the same active ingredient as Prozac) used for ongoing anxiety and compulsive behaviors. A licensed veterinarian sets the right dose — never a website. The prescription is included at no separate cost.

What it is

Fluoxetine is a prescription SSRI (the same active ingredient as Prozac) used for ongoing anxiety and compulsive behaviors. It builds up over several weeks and works best alongside a behavior plan — it is not a quick fix or a sedative.

What it is used for

Veterinarians prescribe fluoxetine for separation anxiety, generalized anxiety, compulsive behaviors. Whether it is right for your pet, and at what dose, is a decision your veterinarian makes after reviewing your pet.

How dosing works (why we don't publish a chart)

The correct amount depends on your pet's weight, species, other medications, and health history — which is exactly why a licensed veterinarian sets it, not a website. Your veterinarian reviews your pet and sets the prescription and dose for your animal. If you see a generic "dosage chart" online, treat it with caution: the safe dose is the one your vet sets.

Clinical references & further reading

If your veterinarian mentioned this medication and you want to read the professional literature, these are authoritative starting points. They are for reference and education — the right treatment and dose for your pet is set by a licensed veterinarian.

Your vet mentioned this — not sure what's next?

Our licensed veterinarian reviews your order and can answer questions about your vet's recommendation. The prescription is included at no separate cost.

Frequently asked questions
