Quick 🧵on the current state of Iota-carrageenan nasal sprays: Efficacy, safety, Betadine shortages, buying options for US & Can. markets.
I-C sprays are the only option on the market that have a real-world randomized, double-blind, placebo-controlled study backing them up. 1/14
This study assessed the use of an I-C nasal spray in 394 hospital personnel dedicated to care of COVID-19 patients. Out of 198 to receive placebo, 10 infections (5% incidence). Out of the 196 to receive I-C, 2 infections (1% incidence). 2/14
@idea_alchemist Damn, so this is how I find out that I also had fakes because my last box is certainly sparkley as hell. 1st is old/likely legit, 2nd is today, 3rd obviously fake. Imo there’s probably a bit of variation, bc it looks like mine from today has maybe a bit larger holes than yours?
@idea_alchemist However, I’ve also had ones with larger holes in the past. Here’s the one today (middle) next to 2 old boxes of valved 9211+. The bottom I suspected of being fake, only because the box came without the usual instruction pamphlet. Sketched me out enough that I never used them 1/2
