Can I use my 1.87% Ivermectin Horse wormer for my dogs

Customer Question

Can I use my 1.87% Ivermectin Horse wormer for my dogs? How would I figure the dosage? I intend to pay for the Heartworm check, but the meds are rediculously expensive...

That's nearly twice the strength used for dogs.

Ivermectin guidelines for canines is 1% solution of Ivomec at 1/10th cc per 10 lbs

This might be helpful for supplies

Most importantly, be sure to get the HW check.

Reply to TheCaretaker's Post: Using the 1.87% Ivermec: So if I gave my dog (approx) 1/20th of a cc per 10 lbs (if I could figure out how to measure that out) then it would be the approximately equivalent?
Expert:  S. August Abbott, CAS replied 9 years ago.

No, it would just be less of the 1.87% . The % is the concentration of Ivermectin in solution - the dosage cc's is the amount of med per lb or kg that an animal needs. You can change the amount of cc's, but need the 1% solution for canine treatment.

These days it's not unusual for help to be necessary, so there's places you can look into if you need to (if you don't need this list, pass it on to someone you think might ok?)


American Animal Hospital Association
Veterinary care for sick or injured pets if abandoned or if their owner is experiencing financial hardship.

Angels 4 Animals
Services range from financial aid to complete treatment.

Care Credit
A credit card company for health care, including veterinary care.

God's Creatures Ministry

Efforts focus on serving the elderly, the disabled, and the
working poor.

Also, call your local Humane Society for options and low cost clinics. If you have a Pet Smart or PetCo in the area, they usually have rescue organizations working through them (not a part of them) and they may be able to provide some help.

Reply to TheCaretaker's Post: Thanks for the links (though I get the idea that you must benefit from some way when you send links?) I'm not poor, just trying to get a round a system that is overpricing an inexpensive ingredient just because it is for a pet...not your fault of course.
Expert:  S. August Abbott, CAS replied 9 years ago.

No, not at all (no payment or benefit whatsoever for the links) - they're just some I've found along the way and feel are helpful.

I totally agree with the inflation of prices for Rx's in both animal and human care. If you can find a Canadian or European pharmacy that will issue supplies to the US it may be considerably less.

Of course finding a sympathizing vet who will let you purchase the meds at their own cost is the ideal solution and some are very cooperative, but of course, not all.

I'm really on your side here. Keep in mind that you can re open this question anytime to follow up and you do not have to press "accept" again - so no more payment necessary.

Please let me know how you do and if you find a better supplier, I'd like to be able to share it with others when the need arises.
