Pet's info: Dog | Shih Tzu | Female | spayed | 10 years old
I gave my dog too much Cefpodoxime 100mg medication tonight. She was suppose to take a half tablet every 12 hours, but I gave her a whole tablet.

Don' t worry about having given her a one off overdose. It is a third generation cephalosporin antibiotic that it's quite often used at high dosages for skin problems. If given continuously at double dosage, I would recommend to check her liver through a blood test but since it just occurred once I would not worry on this occasion.

This antibiotic has a wide margin of safety in dogs, so in general, no serious side effects would be expected from a single "extra" dose. Charlie may have an upset stomach today (mild diarrhea or vomiting), or you may not notice any problems at all. If you have any concerns, it would be best to contact the veterinarian who prescribed the medication for him to see what he/she recommends.

Thanks for using Petco Pet Education Center, formerly Petcoach! This is unlikely to result in an issue other than causing gastrointestinal upset such as vomiting, inappetence or diarrhea. If any of those symptoms are observed, have her evaluated by a veterinarian for further assessment and treatment. Otherwise, she is likely going to be fine. I would just not give her any more doses until 24 hours after the last dose. Good luck and have a good night!
