Question: What’s a better nasal spray, Sterimar or povidone-iodine? It's hard to say. So the Povidone-iodine obviously has some contraindications and it has contraindications mostly because it's been so commonly used in a medical setting and therefore has so much known about its safety and risk profile and I don't have any particular reason to think that the Sterimar is unsafe in any context. And I used it a lot. The only thing I can say anecdotally is I've used the Povidone-iodine intra nasally, and I've used the Sterimar spray intra nasally. And I feel like 0.5% Povidone-iodine is really powerful in wiping out anything we have going on in the nose.
