My cat ate amoxicillin by mistake. Will he overdose or be okay?

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.

Most likely this amount of amoxicillin is not going to cause Theodore any harm. However any medication can cause GI irritation like vomiting and diarrhea. IF you notice any diarrhea I would recommend trying a bland diet for 12-24 hours of boiled chicken and white rice. If this does not help than Theodore should go see a vet for medications to resolve the GI upset. Hope that helps . thanks for using pet coach

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.

Hello and welcome to Petco Pet Education Center, formerly Petcoach. Overdosing of antibiotics is usually not a huge deal. It can cause an upset stomach, vomiting, diarrhea. I would monitor for these signs. I do recommend calling your local emergency clinic (or posting another question) including which antibiotic (Amoxyclav?, Doxycycline?, etc.), as this might change the answer and inducing vomiting might be recommended. Otherwise, just monitor for signs of an upset stomach and skip the next dose. Best of luck with Sumi!

This should be fine as most commonly used antibiotics have wide dose ranges and good safety margins. It does depend on the specific antibiotic though and dosage, to be safe you can either ring your vet for advice or repost with more details here.

Hi, amoxicillin can be used in kittens but how do you give it ? I have witnessed some owners doing more harm then good by administering oral medications to kittens. I would recommend to see your vet so they can be started with a more effective, safe and fast acting injection and then you can continue at home with some oral drops for example. The dosage in kittens would be 10 mg per pound for 5-7 days. Hope this helps,

Hello. While this is not a huge overdose, it is a bit high for an 8-pound cat. Please double check with your veterinarian to see if he wants you to continue with this dose. Thanks for using Petco Pet Education Center, formerly Petcoach.
