Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with today.

How long ago did you give the second dose?

What is the milligram dose of each you have given?

How much does he weigh?

How much peroxide did you give?

Gabapentin 200 mg too much
Taramadol 100 mg too much

I poured as much peroxide down him as I could but no vomit
Expert:  Dr. B. replied 10 months ago.

Thank you,

First, with him being a larger dog and these drugs having a wide dosing range, we have some wiggle room. If he had 200mg Tramadol that is a high dose but not an overdose. As for the Gabapentin, it too is high but not an overdose. That said, the Methacabinol is slightly over at 50mg/kg where the top dose he can have is 44mg/kg. And an overdose of that with the others at high doses could cause drooling, sedation, vomiting and stumbling.

Now you didn't note how long ago this was. If it was <2 hours, you can try to induce vomiting again. We need to be giving at least 20ml of peroxide but up to 90ml for his size to trigger vomiting. If just won't then you can either have him to the ER for injectable Apomoprhine. Otherwise, you can use activated charcoal at this stage. This is available over the counter from the pharmacy (ask for the high strength version in grams, not the one for gas since you will need a lot of these) and works by binding any remaining material in the stomach. For activated charcoal, we tend to give 1-4 grams per pound every 8 hrs. This can be mixed with food to be fed or with water to syringe feed (do note that it stains, so keep it away from white carpets/clothes). This will just limit how much is absorbed and reduce the intoxication risk here.

Overall, most of these aren't overdoses for him. Though with the one and given the sedation these all can cause, the above would be best to limit absorption. So, consider trying again if you didn't give as much peroxide as I noted. Else the other 2 options need to be considered to reduce what he absorbs and avoid any harm. Just in case you need a local emergency vet, you can check @ or via

Response was accurate to what an on call emergency vet told me. The response just wasn't fast enough.

Hi again,

I am sorry you felt that way, though the only delay on my part was that for calculating out the risk for the doses you gave and to type a reply.

Take care,

Dr. B.
