Hi,

We have 3 pigs and have had to take them to the vet for mites. The vet has given them two ivermectin injections (over 2 weeks) and has them on antibiotics.

It's starting to get expensive so we'd like to finish the treatment ourselves.

I've read quite a bit here and I think I have my head around it. I was hoping someone can help confirm please?

I found this product and was checking to see if it's suitable for the treatment:
https://www.aussievetproducts.com.au/products/vetafarm-avimec-50ml

I also found this one. Not sure which is the best or easiest to give them:

Also, is there any actual difference between topical and oral?

Any help would be appreciated. Thanks :)

I wouldn't fool with the horse paste. You'd have to dilute it first, and the general consensus is that topical use of Ivermectin is much safer and tends to be more effective.

Find plain Ivermectin at a local or online farm/feed/cattle/horse company. You can use either the 1% injectible or the .5% pour-on drench (it's blue in color). Otherwise, the first product you linked to should work. You'll just need to make the conversion because, if my math is correct, it's a concentration of 1mg/ml whereas the injectible 1% injectible solution that you can buy at a farm/feed store (assuming a 50cc bottle containing 500mg of Ivermectin) is 10mg/ml.

You can read more about Ivermectin products here:

Note: To use the injectible formula, you'll need a syringe with a needle to draw it up, as the top is similar to an insulin bottle. With the pour-on product, you'll just need a plain syringe to measure the amount out of the bottle. Do make sure that, no matter which product you use, you dose based on weight.

Dosing charts for both the injectible and pour-on products can be found here:

Just out of curiosity, why did your vet put them on antibiotics? Is there another issue besides mites?

The first product should work fine. Note that it is 1000µg/ml which is 1mg/ml
The topical dose is 0.5mg/kg.

So you must adjust the dose properly to the weight of your guinea pig.

OK thanks.

Seems like a lot of people here inject it? Is it more effective than topical? Or easier?

Not sure exactly why. I assumed it was because there were some sores on them from scratching/biting.

Then likely to prevent infection. Watch to make sure your guinea pig does not stop eating.

Topical works the best, in my opinion.

Ivermectin used topically tends to be very safe and effective. Most cases clear up after 3 doses (given 7 days apart), but stubborn cases may take an additional course.

Antibiotics are not usually given to guinea pigs to prevent infections. Antibiotics may be necessary to treat an actual infection, but they have their own set of problems with guinea pigs, namely, GI upset and loss of appetite. Either can be deadly. I wouldn't give mine an antibiotic unless they had something that required that specific treatment.

That's great. Thank you. I'll buy the bird marketed version of Ivermectin then.

I'll come back and confirm I've calculated the dose correctly.

OK I've bought the treatment now. So just confirming the dose calculations for the topical treatment.

The strength of the product is 1000µg/ml. So if my pig was 1kg it would be 0.5ml dose. And if the pig was 500g, it would be 0.25ml dose.

Is that right? How would you apply that topically? It's such a small amount - can you mix it with water or something to apply it?

The suspension is already pretty weak. If you draw up the correct dose and administer it, I think you will be fine.

Your calculation looks correct at 0.5ml for a 1kg guinea pig. That should be very easy to accurately dose with a 1cc syringe.

OK I'm confused. It's a topical solution I bought. I shouldn't give it orally right?

The instructions say to drop it on the skin. In this case the product I bought is marketed for birds and it says to put it on unfeathered area. I assume I put it on the bare skin of the pig or behind the ears?? Does that sound right?

I'm sorry; I wasn't clear. You can use a 1cc syringe to draw up the correct amount to be used topically. You can then put half behind one ear, in the bald area, and the other half behind the other ear.

Yes, as sef says, just do this topically.

Thank you both. That's great. I'm feeling clear about it now and will get on and give them their dose tomorrow when it's due.
