Please everyone remember a cc and a ml are the exact same measurement. So if it calls for 1cc of medicine it's the same as 1ml. Noromectin 1% is a generic Ivermectin 1%. It is also the same thing as Ivomec1%. They are simply made by different companies. The correct dosage for heart worm preventive is .1 or 1/10ths of a cc per 10 lbs of dog or puppy. The correct dosage for treatment of Sarcoptic mange is twice that amount .2 or 2 /10ths of a cc per 10 lbs. Heart worm is given 1 time per month. To treat Sarcoptic mange give 1st dosage and a second dosage 2 weeks later. Easiest way to give is to buy a 1cc leur slip syringe with needle. It is so much easier to read correctly than to use the normal 3cc syringe. Draw up the correct dosage with a new sterile needle then install the cap back on the needle. Then carefully remove the cap and needle at the same time. It's easiest to remove by slightly twisting the cap while gently pulling it. This will ensure that the needle remains sterile and can be used again. The syring you now have without the needle will basically be the same as an oral syringe. You can then squirt the medicine into the dogs mouth up against the cheek not towards the throat this will keep the dog from gagging. Remember to keep the dogs head tipped back so he can't spit it out. Quickly hold his mouth shut and rub his throat and he will automatically swallow. Easier method is to put the amount on a piece of bread in the center then roll into a gall and smear a little peanut butter on it. This medicine taste nasty, not that I've personally tried it mind you, so the peanut butter will help mask the bitter taste. If worse comes to worse and the dog spits it out take it and push it deep into the dogs throat while his head is tipped back. Then again quickly hold his mouth tightly shut and rub his throat and down it will go. I have raised Siberian Hiskies and Alaskan Malamutes for 37 years and have used the above dosages and procedures most of those years. I might also add that the dosages above were given to me by my Vet of 20 years and are completely safe. I have never had any problems using the above. Remember never give to any herding breed dog. And also make sure that your dog is heart worm free. When in doubt, don't give this medicine before checking with your Vet.
I know this thread is pretty old, but hopefully still get some answers. We adopted a dog last week from the local shelter and unfortunately she was tested positive for heartworm. So have been investigating the treatment as I have understood it could be pricy. One thing I don't understand in some postings is told to not to use ivermectin or noromectin if your dog is not 100% free of heartworm. In other websites I have found that they start of with it to kill the immature heartworms before they start with the treatment of the adult worms. Our dog is 60lbs, so the dosage would be 6cc's if I correctly understood it. Also should the noromectin be injected or given orally? Both options wouldn't be a problem though. Have understood that we have to use immiticide to treat the adult worms and keep the dog to bedrest and keep an close eye on her for the first 7-10 days. Keep fingers crossed.
This is an old thread, but I wanted to clear the confusion on dosing with 1% Ivermectin solution. People seem to be WAAAAAAAAAYYY overmedicating their pets. :-(
Lets look at the contents of Heatguard.
For a 50-100lb dog, a pill contains 272 µg (0.272mg) of Ivermectin.
Now, look at 1% solution of Ivomec. It contains 10mg **10000 µg** of Ivermectin per 1 mL (cc).
So, apply a little Algebra to determine your dosage.
X is the unknown dosage (in mL) to achieve the 272ug dosage. 272 µg = X * (10000 µg / 1 mL)
Solve for X (1 mL / 10000 µg ) * 272 µg = X * (10000 µg / 1 mL)*(1 mL / 10000 µg )
*right side cancels and leaves X
(1 mL / 10000 µg ) *272 µg = X X = 0.0272 mL (0.0272 cc)
So you only need less than 0.03 mL per 100lbs. This is a TINY dose. You either need a TINY syringe (think 0.1mL OR 100 mL) to accurately dose, or you need to dilute the solution.
If you dilute 1 part Ivomec with 9 parts water, then you could does at 0.3 mL per 100lbs and use a 1ml syringe for measurement.
(Quick sanity check on the math … If 1ml contains 10000 µg, then 1/10 of a mL contains 1000ug. 272 µg is roughly a quarter of 1000 µg, so .1mL * .25 = .025 mL. Yep. People are recommending WAAAY too high of a dose.)
