Ivermectin 1% Injectable Question

[dawg53]

So I bought Eprinex (eprinomectin). On the bottle it says for cows there is zero slaughter withdrawal and zero milk discard. That it kills lungworms cattle grubs(all stages) Lice 5 kinds, mange mites 2 kinds horn flies chorioptic mange mites were gone completely in tests 8 weeks after treatment. It says it can be used on lactating cows. It also says only can be used topically not injected or oral. I know if a chicken has worms the eggs are not affected and can still be eaten. So Im not sure of the withdrawal of eggs.

I used Eprinex a long time ago and dont use it anymore. It was ineffective against poultry large roundworms, just like Ivermectin.
It would be best to return the Eprinex and swap it out for Safeguard liquid goat wormer or Valbazen liquid cattle/sheep wormer.

I am jumping here, have not read all the posts above. I have used 1% Ivermectin orally (in the water) 1ml per 1lit of water. I used it on my not-laying hens (young chicken and broodies). As per the instructions, it should be given for 2 days and that would help with lice/mites. It does, but the effect is short term, as after a week or so the chicken get infested again. So it has to be given periodically. If anyone has a better experience, please share.

In poultry, people use the 1% injectable orally, topically and they also inject it. There is also a 5% pour-on that people use topically in poultry.

Hi Kathy. I was wondering about using the 1% injectable orally. I'm treating for capillaria and feather mites. What dosage do you use? I mostly see 0.2-0.4 mg/kg (poultry dvm)

I don't know where you live, but in Ontario, my vet administered "Ivomec Injection" at the nape of the neck (as described above). It is an off-label use, and I believe he said to dispose of the eggs for 14 days after the last dose. He gave me the dose for follow-up, ten days later. This was for 2 ex-battery hens, which had 2 types of lice and bird mites, and he assumed they would have worms too. My receipt says dosage of 0.50 ml per bird, per treatment. It seems the 'injection' is only used topically in chickens. Perhaps cows actually do get injected, given their larger body size (and much thicker skin).

Thanks for this post. I trust what a vet says as they have real world experience as well as book smarts. How did the injectable treatment go topically? Our farming stores community also mention giving the injectable 1% as a drop at the nape of the neck for hens.

You quoted a post from 2013, unfortunately that user is mo longer active.
For current and correct information, you'll want to start a new thread. :]

1% Injectable Ivermectin can be use orally, by injection or by drops. Dosing is by weight and is posted below also with a link to the post. Hope that helps.

The dose is not drops. Birds should be weighed or at least have their weights guessed and the proper amount should be given. I have bolded the amount I use.

There are two types, one is injectable, the other is a pour on. The doses are different.

The max dose for 1% Ivermectin is 1 mg/kg which is 0.045 ml per pound. This can be given orally, by injection, or topically.
A five pound hen would get 0.23 ml.

The minimum effective dose for 1% Ivermectin is 0.2 mg/kg which is 0.009 ml per pound. This can be given orally, by injection, or topically.
A five pound hen would get 0.045 ml

The max dose for Pour On Ivermectin is 1 mg/kg which is 0.09 ml per pound. This is given topically only.​

A five pound hen would get 0.45 ml.

The minimum effective dose for Pour On Ivermectin is 0.5 mg/kg, which is 0.045 ml per pound. This is given topically only.
A five pound hen would get 0.23 ml

DO NOT USE this on your dogs unless you are working with a vet!​
