Wormer Overdose!

moonspinner · #1 06/21/12, 07:39 PM

I was just worming my eight week old ND buckling with Zimectrin Gold paste (Ivermectin/praziquantel) when the ring on the plunger slipped and a LOT went into him - about 400 pounds' worth. (He only weights about 15 pounds) I'm worried sick about an overdose. How likely is it he will be affected? What should I look for (I read stumbling, lack of coordination are symptoms) and when would this happen? I don't have any charcoal on hands. Anything else I should be doing?

If he lives 24 hours he should live. The ivermectin toxicity symptoms start within an hour or two. But liver failure can always be a later issue too. Good luck.
Just for future reference, stick the wormer on a plastic spoon then pick it up with your finger and rub it inside his lips. Don't take a chance by using the whole tube of wormer to give it to him. Always measure it out first then just stick it in his lips with your finger.
Ivermectin and prazi have a short half life. An hour or so after he ingests it, it has mostly reached his bloodstream. Like I said, liver failure can always occur over time as the body filters it from the blood. But neurologic symptoms start within an hour or two.

Most of us have done this at least once. He'll *most likely* be OK.

Yup only I gave an entire tube of quest to a 40 pound doe. She loved it. Everything was fine other then $10 wasted.

wow, that is good to know. everything i read on ivermectin said it was safe even if it did get accidentally overdosed. if you use the horse paste, do you do the 3x the body weight dose? like if your goat weighs 100lbs you give up to the 300lb mark?

He should be fine. My friend gave her weanling a tube of Ivermectin and she lived.

Of course in my case it's two chemicals so don't know if that makes it potentially extra toxic. It's been about three hours and just checked on him and so far he seems to be okay. But I'll be on edge at least until tomorrow.

That's the way I use it.

Ivermectin toxicity is almost always self resolving within 24 hours. The only thing that sometimes does happen after that time is possible liver issues. But since it is a young, healthy animal, that is doubtful. It's possible, but doubtful.
But, yes, ivermectin toxicity is usually self resolving.

If it is 1% you do three times, but if you are using the 1.87% you double it not triple since it is almost 2 twice the percentage.
It will not hurt them if you give a bit more.

I put it on animal crackers or Saltines and make a sandwich so I do not have to fight with them

It's been 12 hours and so far he seems okay. He's a very vocal guy, big whiner so hard to tell what would upset him and what's normal. But he was trying to mount does this morning so can't feel too bad. His stool has also been normal - might expect some diarrhea with all that going into his system?

Guilty we did that with one of ours pushed the plunger and it just kept going. My daughter and I looked at each other and said oops! She was just fine.
