question about mites and ivermectin

My 3 pigs all had mites to a varying degree in December. Penny had them the worst. She had fur loss, flaking skin and went wild when I touced her sides. The other 2 were much better, but not perfect.

1. I treated the 2 lesser cases with 3 treatments of Ivermectin (orally) spaced about 10 days apart. I gave them about 2 units of the Ivermectin.

2. I treated Penny with 5 treatments of Ivermectin (orally) spaced about 10 days apart. Also about 2 units.

3. After 3 treatments Penny looked SO much better, I felt I could stop with the other 2 who had lesser cases.

4. Penny had her last dose 5 weeks ago and the other 2 had their last doses about 8 weeks ago.

5. Tonight, I noticed that Lilly (one of the lesser cases) was acting crazy when I was petting her and she has some scabs on her rump and small tufts of fur can be easily pulled out.

6. I rechecked Penny and she is still looking good but seems more sensitive to her fur being "fussed" with than she did a few weeks ago.

My question... do I treat all 3 again?? If so, how many treatments do I do? I did go ahead and give them all one treatment of 3 units orally tonight. Poor piggies! I can tell they are just not themselves. Also, do any of you give the Ivermectin once a month or so for prvention? I hope I didn´t lose anyone here. It does get confusing!!

Also, does Advantage work for any of this? Can you use Advantage and oral Ivermectin at the same time?

Thank you SO MUCH!!!

What do you mean by "two units"? How much do they weigh?

There is always the possibility that some eggs fell off or the bad case you had was so severe that it somehow reinfected the other two (that´s why I asked about dosing).

If they got the correct dose and the area was adequately cleaned and there was no way they were reintroduced, you would think this would take care of them.

I would recheck my doses and just start over again -- and give at least 3 doses. Are there any other animals in your home that have access to them? Mites are supposedly species specific but I wondered anyway.

Advantage will not treat mange mites. I don´t know whether it is safe to use both of them at the same time. I would be tempted to use topical ivermectin instead.

Two units is the about the same as .02cc The vet had given me some small syringes that measure in units. The entire syringe is 30 units or 3/10cc. It just makes it easier to measure that small dose!

The piggies all weigh about 1120g.

No other pets in the house. No chance of reintroduction by another animal. I did scrub the cage, but I probably could have scrubbed it several times.

I probably should have done the 5 doses on all of them. I just didn´t want to give them any more than they needed.

Thank you for your help. I think I will dose them all 5 times.

I had a similar problem that reaccured with one of my males, check the hay isn´t infested or any of the bedding. The vet i used, used ivomec injectable , you can also use it straight onto the skin like advantage. Advantage will do nothing, i have tried a very small dosage (for their weight). I also washed him with Hexocil shampoo which cleared it up (I have to say if your gonna bathe them then keep hold of them tightly as they dont like it. dry them off with a hairdryer so they dont catch a cold) Because of his problem re-curring i used to bath him say every month to 2 months. The reason why they could have re-infected is that one of the lesser cases may have still had the odd one still alive on them and therefore have re-produced and spread! they are horrible to get rid of too.
Good luck

The hay and bedding should not have any mange mites -- they don´t live on hay or in shavings. The mouth parts are adapted to animals. I would be sure your hay and bedding is not stored anywhere there are mice or rats though.

KarasKavies, were you using Ivomec injectable? If so, 0.02cc would have been about the dose -- slightly low, though. 0.02cc undiluted Ivomec injectable would treat a 1 kilo animal. Yours are a bit larger.

Thank you Lynx. Yes, it is the injectable. I am just so afraid to give them too much! I probably don´t give enough and then I wind up re treating and giving them even more! These piggies! I worry about them as much as I do my own kids.

I am going to treat them all 5 times. Should I bump it up to .03??

You could also try it topically at 0.05cc/kg. That would mean you would give 0.056cc for the 1.12 kilo pig. I would put it on the skin behind the ears. If you are using a needled syringe, it ends up looking like 5 or six tiny droplets. In the kind of syringe you normally use orally, it might look like about a drop per ear. Try to get it on the skin and kind of push the hair over and rub it in a bit. You´re not supposed to get it on your own skin -- I try to just rub the fur and avoid the ivermectin.

Do you think it is more effective used topically? The pigs sure would like it better!! I am assuming I would wait until their next dose to do it topically. I plan to dose them every 10 days.

You can do it 7 to 10 days. One of the primary benefits of doing it topically is it may treat some of the other types of bugs more effectively, like lice.

Do you think it is equally effective when used topically?

According to a study in Harkness and Wagner´s book on the Biology and Medicine of Rabbits and Rodents, all methods are effective on mange mites. I just think topical is easiest.

Sounds good to me! They HATE the taste. Although, I have to admit, they sure are cute making all of thie "yuck" faces! It´s so cute to see those little pink tongues. Thanks Lynx for all your help.

I´m thinking the dose may be too low. I have a similar problem myself - except Herbie gets so severe that he has seizures. I use oral dosages mixed with cherry syrup. He loves it so getting meds in him is no trouble. He´s 1 1/2 pounds and they recommend .07cc for him. He got severe again - so he´s back on the 3 doses 10 days apart.

I finally got my own bottle of Ivermectin today along with the syrup. $103.00 - that´s stuff isn´t cheap! But if it works it´s worth it! I plan on trying him on once a month to see if it helps.

I tried treating the whole herd - and that was also a bust. Herbie still gets them and I don´t know how or from where! It´s been driving me nuts for over a year.

Herbie-
0.7cc is not an accurate indication if you don´t also write the concentration of the Ivermectin you use. Are you using injectable Ivermectin? For what animal is it designed? Different kinds have different concentrations.

That is 5 times the recommended dose. I would not use it. There must be something else going on.

That´s either way overpriced or a HUGE bottle of Ivermectin! My bottle of 50ml 1% injectable only cost $35. Maybe it´s a different form of Ivermectin?

OK - I got the box - it´s ivomec - injection for cattle & swine - 50 ml made by merial. 1% sterile solution. The vet said I don´t need to mix it with anything - but the cherry syrup. The dose is .07cc

He said this is the only kind they´ve every used - so it´s what Herbie´s been getting.

Is that right? Or is there something I don´t know here?

I think we´re trying to tell you you were over charged. If you need to mix it with cherry syrup, what is the ratio you mix it at? Saying a dose is 0.07cc is not helpful unless you know the concentration in mg of the drug. It also doesn´t take into account the weight of the animal.

So, the ivomec injection undiluted has 10mg/cc. How much syrup are you adding?

Please read the dosing info at: http://www.guinealynx.info/guinealynx/ivermectin.html#dose

It is clear and should explain what I am trying to get at.

Lynx-
I´m not sure, but I think she takes out .07cc and then adds syrup to it. I´m not sure, though.

Are there several brands of this stuff?? Mine is ULTRAMECTIN (Ivermectin) by RXV Products. It is 1% sterile solution for cattle and swine (injection.) It is also 50ml and I paid $45.00 for it. Sounds like the pricing for it is all over the board too!! I assume as long as it´s 1%, the brand doesn´t matter. Isn´t .07 of ivermectin only still high? I give my girls .02 or .03 they are all about 1100 grams.

As if this weren´t confusing enough!!
