I plan to start using appropriately diluted povidone iodine solution as nasal spray and mouthwash when I’m in contact with (or proximity to) strangers. I’m pretty comfortable using Betadine 10% as the base for mouthwash (diluting it with water since the commercially sold mouthwash version is somewhat difficult to procure.)
I’d love any insights/thoughts on the correct product to use as the base for nasal spray (prior to mixing with saline), as the above protocol does not reference a particular product, and the additives in different povidone-iodine solutions seem to vary a fair amount.
The linked article indicated that 10% solutions were widely available on Amazon, and links this one, but doesn’t seem to give any indication why he picked that one in particular—just wanted to check if you might have seen this reasoning somewhere/if it exists.
I’m not familiar with Chris Masterjohn—his web page looks like he’s a content creator trying to leverage his Nutritional Science PhD into being seen as knowledgeable about a wide variety of things—is this human known to say true and useful things?
Thanks Zvi, these are super informative!
Use of povidone-iodine as mouthwash and nasal spray looks promising as prophylaxis (and potentially treatment, but lower confidence on that.) The study Zvi linked (https://jamanetwork.com/journals/jamaotolaryngology/fullarticle/2770785#ooi200049r25) appears to be the latest in discussions occurring in otolaryngology since April (https://www.google.com/search?q=povidone+iodine+nasal+spray&oq=pobidone&aqs=chrome.1.69i57j35i39l2j0l2.2542j0j4&client=ms-android-att-us&sourceid=chrome-mobile&ie=UTF-8). Other informative articles here (https://journals.sagepub.com/doi/full/10.1177/0145561320932318) and (https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3563092).

I’ve got this Povidone Iodine Prep Solution USP, from a Chris Masterjohn recommendation. He suggested (back in May) diluting it 20x.
Thanks for the info! Two questions:
