Prof Trevor Marshall (@trevmar) sent me this image via twitter. He refuses to say where it comes from. I'm not sure what it is. Merck (who invented ivermectin) says it has a half-life of 18 hours in the blood. Others have come up with other numbers, as high as 30 IIRC. On this chart, the half-life appears to be about 50 hours. It could be half-life in the tissues, esp. in fat. ???

What is the safety limit on dosing ivermectin? Ive been talking with other providers in a covid group. Theyre asking about outpatient treatments and im tertiary care not primary and my recommendation is to consider ivermectin with doxycycline.

This safety study found that 10 times the FDA-approved 200mcg/kg (approved for the treatment of scabies) is safe, esp. there were no signs of Central Nervous System problems.

This clinical trial is the most extreme dosing that I've heard of: 1200mcg/kg per day for 5 consecutive days! I wrote code to figure out how high ivermectin would get in the blood with that dosing: max is 1974, just under the 2000mcg/day that the safety study deemed safe.

The upper-limit on ivermectin dosing is actually unknown, because no one has tested high enough doses to evince problems!

Are you in the US? In the US, off-label use is probably less of a liability issue if they stick with 200mcg/kg.

Doxycycline is a good idea!

This study is a bit confusing because it compared IVM + DOXY to HCQ + AZT, but IVM + DOXY showed good results.

In Uttar Pradesh (India's largest state, 204 million people) the government is endorsing IVM + DOXY.

In this not-yet-reported trial, they're trying:

Treatment: Ivermactin 6 mg 2 tab stat, cap (that's 200mcg/kg for ~65kg person, if memory serves)
Doxycycline 100 mg 1 cap BD 5 days

This study (recently published in a journal here) had good results.

The dose of ivermectin was 0.2 mg/kg single dose. Doxycycline 100 mg daily was given to patients aged 8 years and above for 10 days.

Dr. Aguirre is a Peru MD who believes more ivermectin is better, depending on the patients condition. His protocol's 4th revision graphically here, his day-old commentary here, and my Excel interpretation of his latest protocol here. (Argh: reddit will just show you my post, with two images both truncated. CLICK the image reddit shows to go to the tweet, then click the images there, using the right-arrow to see the second image (in case you're not twitter-adept).) The second image shows that his highest dose is 857mcg/kg.

I'm not an MD and this isn't medical advice.

If it was up to me, and I was not concerned about liability issues, I would go with Dr. Aguirre's protocol. It is battle-tested and refined. It also has lots of guidance about other drugs and treatments.

IMO liability should be a non-issue because of ivermectin's ridiculous safety record: 4+ billion doses given to billion(s) of people over 20+ years with < 6-8 deaths (and those are ambiguous, patients had myriad issues). I don't have the background to judge whether that would carry the day in court, though.

If your friends want the "cover" of using the FDA amount, that's 200mcg/kg. I would suggest giving that dose on days 1 - 3, then doing a PCR after a week and giving a second dose of the same size if the patient is still covid+.

And 10 days of doxycycline: it's safe and cheap, and appears to be helpful.

Any questions?

I hope this helps!

There are risks to every medication. Not too worried about ivermectin. Thank you so much for this post. It is well thought out and properly sourced. I did have an issue opening the Twitter post. It told me it was not available to me. But everything you shared is extremely helpful. Its a shame we have to be so concerned about liability issues in the states and even you have to write this isn't medical advice etc. Really appreciate your thorough input.

You're welcome! I've been ivermectining (it's a verb in my world) since March. It's nice to be able to occasionally share what I've learned where it matters, esp. treating patients.

If it's not a violation of HIPAA or a huge hassle, it would be great to hear about what your friends do and how well it works!

What is "free drug"?

90-95% of Ivermectin quickly binds onto albumin in the blood. That's consistent with the charts, so I'm pretty sure that's what they're measuring.

Not combined with any thing, perhaps.
