My dog ate a ciprofloxacin. 500 mg. Can it hurt her

Dr. Kara :

Hello, I'm sorry to hear about your girl and I'd like to help.

Dr. Kara :

How much does she weigh?
Does she have any pre-existing medical conditions?

JACUSTOMER-55ftcily- : She weighs 17 lbs. She is healthy
Dr. Kara :

Thanks very much. We do sometimes use this drug in dogs, though not often as it is not as well absorbed as some other drugs in its class (the fluorquinolones).
Let me check a maximal dose for a dog her size.

Dr. Kara :

The common maximal dose is 20mg per kilogram of body weight.

Dr. Kara :

At her weight that's roughly 154mg.
So she's had about 3X a normal dose.

JACUSTOMER-55ftcily- : What should I do?
Dr. Kara :

You might see some gastrointestinal upset (vomiting or diarrhea) but this is unlikely with a one time dose.

Dr. Kara :

In some very sensitive dogs you can see stress on her kidneys or liver and crystals in her urine.
How long has it been since she ate it?

JACUSTOMER-55ftcily- : 20. Minutes
Dr. Kara :

So you can choose to try and make her vomit it by giving her one tablespoon of 3% hydrogen peroxide orally, then take her out and run her around to get things bubbling and get her to vomit.

JACUSTOMER-55ftcily- : What if I do nothing?
Dr. Kara :

If no vomiting then you can repeat in 10 minutes.
If you don't have hydrogen peroxide then you can just feed her frequent small meals as it is poorly absorbed with food on the stomach. And get her to drink as much as possible to flush the rest out as quickly as possible.

JACUSTOMER-55ftcily- : Thank you for the help.
Dr. Kara :

Odds are that she will be absolutely fine with one high dose, especially if she's kept well hydrated and fed frequent small meals to decrease absorption. Especially as she's basically healthy.
I would be more concerned if you told me she has a history of liver or kidney disease.

Dr. Kara :

If you choose not to induce vomiting you might feed her a bland diet of 50% boiled hamburger or chicken mixed with 50% boiled white rice. This will help decrease the odds of gi upset.
You are very welcome.
Can I answer anything else?

Dr. Kara :

And giving her yogurt with active live cultures will also help decrease the absorption as Cipro is bound by dairy products.

Dr. Kara :

You can add a tablespoon or two to each meal for thre next 12 hours.

Dr. Kara :

Are you still with me?
