My 50lb dog ate human amoxicillin. Will he be okay or get sick?

The amount of antibiotic he ingested is higher than typically used so he may experience some gastrointestinal issues but it should not be toxic. You could give him a probiotic for a few days (Proviable or Fortiflora) and monitor for any abnormal signs. If you notice anything abnormal then he should be examined by a vet for treatment.

Oh no, that was naughty of Baxter! He took about five times the recommended dose of ampicillin. This will likely cause a reaction in the form of vomiting, drooling, and diarrhea, but more serious effects such as tremors or seizures. If you see tremors or seizures, Baxter will have to see a vet immediately. Should you see vomiting and diarrhea, withhold food for 12-24 hours, then feed him a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in his normal diet.

Hopefully Chappo will only experience GI effects for this overdose. However, in some cases Amoxicillin overdose can cause neurological side effects, elevated liver enzymes and even cardiac issues. Do not give Chappo any more amoxicillin until you are able to get him in to your veterinarian.

I would not be overly concerned, although the recommended dose is 5-10mg/lb (and an 8lb cat would have consumed approx 15mg/lb) it does have a wide safety margin and overdose symptoms are very rare. I would expect some mild gastrointestinal upset and a probiotic would be helpful to reduce the impact on the natural gut balance

Hello. Amoxicillin is a very safe medication with a large range of appropriate doses. I would not worry at all about this one time overdose. Just continue with the 1.5 ml at the next scheduled time. Thanks for using Petco Pet Education Center, formerly Petcoach.

Thank you for submitting your question regarding Archie. I do recommend that he sees a veterinarian right away. I would take the prescription bottle with you to show the veterinarian. Vomiting may be induced depending on how many tablets he may have consumed and based on his current weight. I hope this information helps!

Hello. This is twice the normal dude for him, but this is a very safe antibiotic with very low chance of toxicity. I doubt that Skipper will suffer any side effects, but to guard against nausea...try to feed him a little to reduce the chance that he could vomit . Other than the small chance of upset stomach, this is not a problem. Thank you for using Petco Pet Education Center, formerly Petcoach
