Questions on Ivermectin and Lice

[casportpony]

@Casportpony, post #19 needs fixed. I use appox. 0.45 per Bird not pound.

Thanks! changed to say this:
0.045 ml per pound and 0.09 ml per pound

0.45 ml per pound would be way too much.

I'm guessing this ivermectin is the 1% injectable, not the 0.05% pour on?

Yes that is a correct guess, it is the 1% injection, thanks for pointing that out. However, as to clarify a little more, the 1% (0.01 no percent) injection solution that I use can be given oral, injection, or topical treatment in many instances and applicable after proper dosage is determined.


I guess if the 0.5% proves to allow for such internal modes, one could simply dilute it down to the acceptable percentage as required and recommended per species. But I have no experience with the 0.5% = 0.005 (no percent) and do not make comment for that label.


The 1% 250 ml I have will treat all 6 of my dogs, all my birds, and if needed myself monthly for the next 2 years, and I will most likely have some left over when the bottle (vile) expires.

Edited to correct typeo, errors, removed/corrected text of errors. Was not stepping on toes.


1% = 0.01 (One percent)
0.5% = 0.005 (Half percent)

People need to understand that there are no sucking lice on birds, they bite and irritate but do not suck fluids. Therefore any 'treatment' given to the bird internally via injection or orally will not kill lice. Only topical treatments will kill lice, that is why we use the pour on and not the injectible.

When I give ivermectin orally it *does* kill lice, and usually in 24 hours.

Truth be told, I've never used the pour on.

This is one that I treated in June. She was given ivermectin horse paste orally and all lice were gone in 24 hours.

2015 peahen that weighs 3.2 kg and was given 0.15 ml of 1.87% ivermectin paste, which works out to ~0.9 mg/kg.

Sorry... major typo on my part - no such thing as 0.05% In bold are the products available in the US. The other numbers are there just to help people, myself included, understand the math. Please check my math and let me know if I got it right this time!

0.1% = 0.1 mg/ml
1% = 10 mg/ml (injectable for cattle)
10% = 100 mg/ml
100% = 100 mg/ml

0.05% = 0.5 mg/ml
0.5% = 5 mg/ml - Pour on for cattle
5% = 50 mg/ml
50% = 500 mg/ml

0.08% = 0.8 mg/ml - Sheep drench (oral)
0.8% = 8 mg/ml
8% = 80 mg/ml
80% = 800 mg/ml

1.87% = 18.7 mg/ml - Horse paste

As far as I know there is no such thing as 5% ivermectin. 5% means that it would have 50 mg ivermectin in 1 ml. Products readily available in the US are:

• 1% (10 mg/ml) injectable that can be given orally, by injection, and I have read about people using it topically. Maybe I will try that next.
• The pour on is 0.5% (5 mg/ml), not 5% (50 mg/ml). It is meant to be used topically, not orally, and never by injection.
• 1.87% horse paste can be given orally, and I think I read about someone using it topically. Maybe I should add that to my list of experiments.
• Ivermectin Sheep Drench is 0.08% (0.8 mg/ml) and is given orally.

Quote: The pour on is half the strength of the 1% injectable, so no dilution is needed. And the 0.05% was a type, should have said 0.5%.

No such thing as 0.05%, nor is there a 5%.

And your 1% bottle could last years past it's expiration date... I know mine still works, and I think it expired several years ago.

Okay, thanks (where is that crow pie?) I boo-booed big-time on adding the % to the decimals (0.01% and 0.05%) that I typed, it should be as you stated (0.5%) or 0.005 (no percent)..... I was/am not trying to step on toes nor trying to be a Smart-Axx.

Also thanks for confirming the expiration date issue. I never kept meds past the due date and hate the thought of throwing away and giving it away (the excess) due to cost.



I do dilute my meds as needed to reach the more diluted levels and I failed to make that clear when I wrote
"However, I will say that the amounts of dosages are different for specific animals and humans, so the solution needs to be researched as for what dosage is acceptable for the lively creature." and latter "one could simply dilute it down to the acceptable percentage as required and recommended per species".


just to clarify to any others on my mistake.....

1% ivermectin is 0.01(no percent)
0.5% ivermectin is 0.005(no percent)

I re-edited my prior post to include the corrections.

That looks correct to me!

1% ivermectin is 0.01(no percent) = 10 mg ivermectin per one ml
0.5% ivermectin is 0.005(no percent) = 5 mg ivermectin per one ml

I will take some pictures of the dosing info for all the species and post them later.

@BobDBirdDog , forgot to mention that I checked the expiration date on my injectable ivermectin, and it says it expired in 2011. I know it still works because I use it orally for lice, and all lice were gone in 24 hours. The color still looks fine, though I'm not sure i'd wanna give it by injection, so I'll just stick with the oral route. Note that the bottle has been store in a cool closet and has not been exposed to sunlight.

@casportpony can you please give me details on treating lice with horse paste ivermectin? I gave my chickens pea sized dabs yesterday. I now know that was way too much. They seem fine though. Lice are not dead yet. I'm wondering about egg withdrawal? I know people use ivermectin internally so I'm not too worried about ingesting some... Thank you for any info you can share!
