So yeah its real. The medicine is exactly the same for horses and people. Its dosed the same, by the pound (or kg) bodyweight at 0.2 mg./kg. or about 4.5 mg / 50lbs. The product makes it easy to dose to the nearest 50 lbs body weight on the applicator (its an oral paste). So for most adults, one dose will be either the 150 lb dose (4.5 mg x 3 - 13.5 mg) or the 200 lb dose (18 mg). The human pills come in 3 and 6 mg doses for comparison. In this product (durvet oral paste) there are about 8 doses for a 150lb individual. If you get symptomatic covid, you can take one or two doses a day for at least 3 doses. However if you are still feeling very sick you could continue to dose until you got to the end of the tube. ~ half the tube will be enough for many people *if you start dosing early after symptoms.* Its up to you if you want to be more aggressive and take 2 doses a day, but one will be enough for many. It is an antiparasitic but also an antiviral and a blood thinner, which is good because covid causes blood clots, but if you are going to use it simultaneously with aspirin be a little conservative. The drug interactions with this drug are minimal. The link has a list of drug interactions. You really only need to worry about the *serious* interaction drugs, which seem to be rarely used drugs. Some of the other drug interactions like the statins have never been clinically observed. The drug has been out 50 years. It will be safe to take with the mild/moderate interaction drugs in the doses I have mentioned. If you were to suddenly slip and swallow the entire tube at once (dose for a 1250 lb horse) you might feel a bit sick for a day, you might have some moderate neurological symptoms like temporary change in vision. You would not die. For prophylaxis, the recommendations are between 1 and 2 doses a month for long term, which is about a quarter to a half dose a week. That protocol I linked to seems to have changed their recommendation to up to 1 dose a week, which is frankly overkill, unless you are 90 with emphasema in a nursing home. I would shoot for 1/4 to 1/3 dose per week if I was an older person in reasonable health. That is a 50 lb dose (4.5 mg) by the plunger on this product. At that rate, you would complete one tube every 6 months. That is a low cummulative dose that should be safe enough to use for several years. They have used this drug monthly on livestock and also Africans for parasites. Farmers use this product alot on themselves for scabies, because they are familiar with using the drug on their animals. Here’s some studies on Ivermectin as a prophylactic for covid. https://c19ivermectin.com/#prep Here’s some guy using it for scabies (video) https://www.maximpulse.com/permethrin/ivermectin-horse-paste-for-scabies.html Remember if you use it for symptomatic covid, one dose is abt 3 or 4 50lb increments (notches) and you should take at least one dose a day for 3 days. If you decide to do the prophylactic, just one 50 lb dose (notch) once a week or about 4.5mg If you think you have been exposed, you can take a half to a full dose before you have symptoms with no penalty. You could try to get the ivermectin prophylaxis from a doctor or from a mexican pharmacy. It will be a little more expensive. Likewise, you could get prophylactic hydroxychloroquine which they would prescribe at about 400 mg a week, which is a safe low dose that you could take for a long time. If these regimes dont completely block a covid infection, they will slow down the virus so that you will likely only get a mild case. Feel free to ask me additional specific questions as I have done quite a bit of research.
