Scientists are not sure whether those side-effects come from the dying parasites or the ivermectin itself:

"Ivermectin is well tolerated compared to other microfilaricidal agents (i.e., thiabendazole, diethylcarbamazine). Adverse reactions (i.e., pruritus, fever, rash, myalgia, headache) occur commonly during the first 3 days after treatment and appear to be related to the extent of parasitic infection and systemic mobilization and killing of microfilariae. The majority of reactions can usually be treated with aspirin, acetaminophen and/or antihistamines. Adverse effects tend to occur with lesser frequency during periods of retreatment."

If you read this list of side-effects, Aspirin also looks as scary as ivermectin: https://www.drugs.com/sfx/acetylsalicylic-acid-side-effects....

BTW: "BNF is only available in the UK

The NICE British National Formulary (BNF) site is only available to users in the UK, Crown Dependencies and British Overseas Territories."

I am not sure how people do not have even slightest intuition about overdosing something. There are quite strict limits to everyday over the counter medicine. For example you should not take more than 1000 mg of paracetamol at time and not more than 4000 mg a day. Would the same people who think that it is normal to take 5 times in a row the dosage that is mostly prescribed for several months also take 20000 mg of paracetamol when somebody claims that it will cure covid?
