Ivermectin

Ivermectin uses and doses in Rabbits

Ivermectin is used topically to treat ear and fur mites

Fur mites can be treated with a .5 cc drop of the pour on ivermectin behind the neck of a 10lb rabbit. and redoes 7 days latter see exact dosing by your rabbits weight below.

Ear mites can be treated with topical application of 3 drops the injectable ivermectin in each ear of a 10lb. The injectable ivermectin is preferred for use in the ear becuse after they are cleaned with olive oil the skin is raw and the injectable ivermectin is easier on the rabbit, the pour on has an alcohol carrier base and will stink the already raw ears . See exact dosing by your rabbits weight below.

Drug class:

Ivermectin is a semi-synthetic antiparasitic medication derived from avermectins, a class of highly-active broad-spectrum antiparasitic agents isolated from the fermentation products of Streptomyces avermitilis.8 Ivermectin itself is a mixture of two avermectins, comprising roughly 90% 5-O-demethyl-22,23-dihydroavermectin A1a (22,23-dihydroavermectin B1a) and 10% 5-O-demethyl-25-de(1-methylpropyl)-22,23-dihydro­-25-(1-methylethyl)avermectin A1a (22,23-dihydroavermectin B1b).8 https://go.drugbank.com/drugs/DB00602

Dose:

• max dose up to 0.4mk/kg*

• SC dose may also be given topically**

0.1-0.2 mg/kg SC(injected), repeat in 14 days Ear mites, James Carpenter: exotic animal formulary 4th edition

• Ivermectin Dosage(injectable formula) Topically or Orally

up to 0.4mk/kg "The 1% is 10mg/ml. undiluted, it would be 0.072 ml. Dilute it 1/10 to make it 1mg/ ml, so then a dose volume of 0.72 ml which is much easier and safer to draw up and dispense." Diluted with propylene glycol can also be given orally From Dr. D: Exotic Veterinarian

• For the pour on (3%) (Topical use ONLY)

Dilute 1/5 and the dose would be the same. Again 1mg/ ml. Dilution" dose stays the same 0.4mg/kg

Now my personal horror stories for not knowing better .

First time did not make the corrolation found ear mites in 2 of 10 bred does, did a herd treatment .

2-4 days latter Indy miscarried she had never even missed before , then Fred, aborted , then 3 litters didn't materialize , and the rest had small liters, or DOA kits .

Because Ivermection has a delayed reaction I didn't correlate.

The second time I did a herd treatment as I was breeding, 15 does bred , 9 did not take, 4 had unusually small litters .1 had deformed kits.

We will not use Ivermection in pregnate does for treating ear mites . All forms of ivermection are not safe to dose in pregnant does or ones you want bred. . Our treatment cut off is no less then 7days prior to breeding . And not until after they kindle. During pregnancy olive oil , sweet oil , can be used to control outbreak. Or other treatments .

notes

Ivermection is an off lable drug for rabbits so their is not an offical statement which is Why i am going to shout this. High risk of complications when used during pregnacy . If you can abort the litter or have to to treat mites fine . But if someone can not.lose the litter and has other options they need to be aware that it has a high probability of causing an abortion or birth defects. The conclusion of the litature review was done to see whether it was safe for HUMANS which is why it stated , many adverse effect is mice and rabbit. But determined it was safe for pregnant HUMAN use at the lower dosage . Because multiple studies do in fact say to avoid in pregnate rabbits . As well as my veterinary consult, and multiple.other breeders who found out the hard way.
