Excede antibiotic is given in Muscle Tissue by mistake

[vrkolli]

I recently administered Excede to a cow for treating mastitis, as prescribed by the vet. However, I accidentally gave the injection in the neck muscle instead of at the base of the ear as directed.

What are the possible consequences of this mistake? Has anyone else had this happen, and how did it turn out?

Thanks in advance for any advice or shared experiences.

Even when we try hard, everything can't be perfect, and the base of the ear doesn't give a lot of margin for error, anyway. That's one of the drawbacks to using Excede, but it is a really good product.

The biggest problem is not the location so much, but that you gave it in the muscle instead of under the skin. I've given a lot of it high up in the neck, close to the ear, and figured it was good enough. Cattle fighting you in a squeeze chute don't leave a lot of ear access and sometimes you just have to go with it, but I've always made sure it went under the skin. Still, though, I'm sure your not the first person who has put it into the muscle, it has almost certainly been tested that way, and there would be specific label warnings if it was dangerous to do that.

So, consequences will likely only be tissue-related - tissue damage to edible muscle, and drug residue in tissue longer than desired. Your mistake probably won't actually hurt your cow, and the results should be adequate. Stop worrying, but get it right next time or use a different product.

Were you treating a beef or dairy cow? Did the cow have respiratory problems also?

For mastitis, I am surprised the vet didn't recommend the teat infusion method. The ear site has a quicker and more effective response to respiratory infections, but less effective than the teat infusion for mastitis.
