JACKSONVILLE, Fla. -

You've heard about devastating medication errors happening with people, but pet owners should know it can happen to four-legged patients, as well.

The Food and Drug Administration has issued a new warning because investigators are finding prescription mistakes happen with pet meds, too.

Sarah Schuck learned that painful lesson with her beloved Labrador named Rafter.  A collar, pictures and fond memories are all she has left.

"It was really hard," said Schuck.

Hard, because it shouldn't have happened. Schuck said the drug store that filled Rafter's prescription messed up.

The bottle's label said to give rafter 'two and one fourth teaspoon' of medication.

Trouble is, Sarah said, the dosage her vet called into the pharmacy was for much less medication, 'two and one fourth CC.'

The overdose, combined with Rafter's already bad health, was too much. Schuck had to put the dog to sleep.

"It was a tough realization," said Schuck.

Experts say this mistake happens all too often. FDA investigators discovered errors stemming from simple issues like:

  • Look-a-like packaging
  • Drugs with similar names
  • Bad handwriting

Veterinarian Tom Cox, of Timuquana Animal Hospital on Jacksonville's Westside, said pets aren't always as tough as people think they are, and simple mistakes can easily be deadly.

"Cats aren't dogs. Dogs aren't people," warned Cox. "Each species if different on the way drugs interact inside."

Cox says he's seen times when abbreviations on prescriptions have caused pharmacists to fill the wrong amount...and owners to give too many doses of medicine to their pets.

"We have two technicians double-check and then they bring it to me and make sure it's the right dosage, because mistakes happen everywhere," said Cox.

And while we've learned how to make ourselves better when we don't feel well, like treating a headache or an upset stomach, we can't just give the same pills to our pets.

Dr. Gary Roberts, a pharmacist and owner of Roberts Pharmacy, sometimes fills prescriptions for pets.

"Medications for humans don't work the same way in pets," said Dr. Roberts.

He said animals can be especially sensitive to medicine, so that's why pharmacists, vets and pet owners need to double check everything they do and never go against doctors' orders.

"Drugs are not broken down the same way in your pets as they would be in the human body," said Dr. Roberts. "So dosing wouldn't be pound for pound necessarily."
