The position all governments should take is that while they don't know for certain how much benefit Ivermectin will provide, they should disclose what ranges of dosages would be reasonably safe.
Governments should not be allowed to have or hold any secrets, such as all the Big Pharma vax trial test results and contracts, etc. More generally, Governments should get out of the business entirely. The free markets, along with people not throwing away their own personal responsibility and obligation they have to themselves and even to each other, are perfectly capable of determining and publishing this info. Further, it is governments who have censored and charged doctors with civil and criminal and taken their govt "license" away that they don't need anyway... for talking about and prescribing Ivermectin. Which so many regions including now Brazil have proven some positive effect, and zero negative effect. But Big Pharma and Fauci the puppetmaster refuse to run any significant US studies, refuse to release complete study methodologies and results, etc, and have been lying on TV for the last two years. If the Govts were stores in the free market, they'd go bankrupt because they're so bad that no one would shop there.
For instance if the LD50 of Ivermectin is the same as a rat, 51 milligram per kilogram, it should be 5.1 grams for a 100-kilogram (220 pound) person, they should disclose that approximate number for what it is, and further what actual dose would likely be 'safe':. Perhaps 1/100 of that amount, or whatever they believe it to be.
Human prescribing information is easily found on the internet, and included in various physician references and the drug datasheet. If this was actually a free market, you'd be able to use anonymous cryptocurrency to pay a token cost to subscribe to whatever competing medical info services you prefer. You'd be free to start your own services. You'd be free to walk into any pharmacy and just buy whatever you wanted to ingest, with or without a doctor. You'd be free to create your own drugs and test them on yourself, and people would be free to come to you to try them and rate the product on the internet. You'd be free to crowfund whatever high quality research you wanted. You'd be free to see and pay whatever docs you wanted based upon what works for you, at honest prices because govt wouldn't be subsidizing medical school loans, big pharma, big insurance, and big lawsuit... thus driving up prices, especially upon those who refuse to play in that game. Don't try to claim govt is there to help cover sick people when it intentionally murders people with impunity every single day. That's what charity is for, before you eschewed that personal responsibility to govt too, and of course govt promptly abused you with that power as usual.
