Additional note: The Ivermectin I have, which was bought in May 2021, says it’s good until April 2024. Somewhere I read that it is still good, but the strength has diminished. I’m wondering if I can still take the ivermectin, and if the strength has diminished, perhaps I need to take two 12mg pills instead of one. Any advice?

A lot depends on the conditions in which it is being stored. If you have it in a drawer or a hot area the chemicals will deteriorate to a certain extent over time. How much deterioration and time is unknown because I don’t believe anyone has actually done a study to find out. However, in general, if you have been storing them in a refrigerator or freezer you will slow down the deterioration process considerably. And if you stored them in a vacuum as well as cold, you will extend their useful life as well even longer. Again since there are no studies the exact amount of preservation is unknown. I would imagine that potency will reduce to a certain degree over time probably on a logarithmic scale. Under ideal conditions you can probably store the pills for up to 10 years with just a slight drop in potency, perhaps 10 to 20 percent. So I would say don’t worry too much about how effective they may be for quite awhile if you are storing them for long term use. I am not a pharmacist or chemist, so consider this an opinion rather than professional advice.

If stored correctly they should last many years with a small potency drop.

I store them in air tight leak proof ammo cans with using Desiccant Bags.

I’m not a scientist. I think it has a long shelf life. Start using it and when it’s gone get a fresh supply. Prphylactic dose is 12 mg per week. I haven’t read any reports about it breaking down within a year or 2. I buy 12 mg for the family and 3 mg, which I cut in half, for the dog.

Strictly humor: I’ve been with the same GP for (54) years – really great doctor. For all of that time (that he continued to get kickbacks on fresh scripts), he was strict about “getting rid of them once out-dated per the label”. When Covid hit and doctors were threatened in NY by our “Caligula” Governor re: any treatment but the shot and I informed him I was going to self-treat with hydroxychloroquine and azithromycin but the Z-pack I had was a year out of date, he said, “Don’t pay any attention to those drug dates – if it hasn’t changed color or structure it’s likely fine!”

I agree with the writer that discussed the effects of “storage” and also use the refrigerator but would add that a chemist once told me that not all drugs take well to being frozen.

A doctor on a group I am on says that IVM lasts long and if it is no good you will see deterioration in the pill.
