Customer Question

My boxer ate a flector patch--(diclofenac epolamine topical patch). What can I do until the vet opens. He vomited the patch--I think he had it in his stomach for several hours before this!!

Thanks for the questionCustomer

It is good that the dog vomited up the patch but the possibility remains that some of the active ingredient has been absorbed. This is an unusual poisoning that few vets will have encountered, I have found the following information.

" Even a used Flector® Patch contains a large amount of diclofenac epolamine (as much as 170 mg). The potential therefore exists for a small child or pet to suffer serious adverse effects from chewing or ingesting a new or used Flector® Patch. It is important for patients to store and dispose of Flector® Patch out of the reach of children and pets. " Reference LINK

Given the above information the best thing to do is to contact an emergency vet and explain what has happened. Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) for which there will be no antidote. These poisoning are treated on a symptomatic basis, make the dog vomit, make it swallow activated charcoal to mop up any drug in the alimentary tract and then control such symptoms as vomiting, diarrhoea, stomach ulcers or anything else which occurs.
