What yall medical brehs think about this?:lupe:


There are a lot of nasal sprays out and they may be helpful but it remains to be seen whether they make a difference. The issue is that it's only disinfecting interior surfaces, it's not like it cleans out your system, and if you're sick then most of the virus is inside your system not just on the passage surfaces. So it is unlikely to help you if you're already pretty sick, but if you use it right after you've been exposed, while the virus is still in your pathways, it might knock down the viral load enough that you don't even get sick. I'm not sure if someone can really use it 5x a day every day just to try to continuously keep the virus from getting in through that passage (cost? unforeseen side effects?), but for folk like health care workers it's at least an interesting thought.

The most suspicious warning sign I see is that they're advertising "reduces viral load", but they're not saying anything at all about reducing infection rate, reducing symptoms, or helping people get better quicker. All the information I've seen solely discusses viral load and says nothing about patient outcomes. So does that mean it's not actually helping patients, or is it that they just don't know enough yet? They've only completed Stage 2 trials but Stage 3 trials are supposedly underway and when those are done hopefully we'll know more. The skeptic in me wonders if it's just cleaning the inner nasal surfaces, after which you check and see there's no viral load on the surfaces, but by then it may be too late and the virus is already doing its thing in your system anyway. We've got to have trials that show whether infection rate and/or symptomatic rate and/or hospitalization rate actually are reduced.

Here's a rundown of some of the other nasal sprays out there:
