We are ready to get started (for our horses, of course!) So much information has been posted already but search function doesn’t work!
Can you all give us some guidance?
Edit to add: We do have horses and are familiar with Ivermectine. Just looking for guidance on dosage and frequency of use in humans.
Multiplying weight by 1.5 seems to be the consensus (but have seen that’s not necessary?).
This site has the correct dosing information: https://covid19criticalcare.com/covid-19-protocols/i-mask-plus-protocol/ It ranges from 0.2mg/kg of body weight for chronic prevention to 0.4mg/kg of body weight for post-exposure prevention, to 0.4 to 0.6 mg/kg for early treatment. Page 2 of the handout has a dosage chart by body weight for the 0.2mg/kg dose. For Durvet 1.87% ivermectin, a 6.08g tube contains 6.08g*1.87/100 = 113mg of ivermectin. There are 25 notches on the applicator so each notch =113mg/25 = 4.5mg/notch. For the 0.2mg/kg dose, this works out to about one notch per 50 lbs of body weight, which is the dosage marked for horses on the applicator. Multiply by 2 or 3 to get to the post-exposure or early treatment doses.
I haven't checked your math, but, thanks for doing it so eloquently!
I would bet that it is correct.
