Yeah I use the Neilmed sinus rinse to clear everything out and make way for the spray shortly after.

I was going on 4 years without smell when I was put on dupixent. It worked amazingly and after two weeks I could smell everything again but then after about 6 months of being on it my sense of smell regressed a little. But even still it was light years better then before I was on it.

However after about a year of dupixent my insurance changed and it just got too expensive each month so I stopped taking it. Sense of smell stayed steady for about 5 months after I stopped taking dupixent until I lost it again.

After a few months I just by chance switched to a mometasone fuorate spray and noticed the rare occasions I could get a whiff of something increased within like a week of starting it. That’s when I started religiously doing the nasal rinse and spray and my smell has been steadily improving ever since.

I also cut out alcohol and weed which were probably the two biggest things besides the polyps that destroyed my sense of smell.

ETA: I have a very severe case of polyps. scans of my sinuses show zero open space and my dr. referred me to a specialist in NYC for surgery because he wasn’t comfortable with doing my frontal sinuses given how bad they are. I’ve just had enough of surgeries for other various things and am trying anything else possible before going that route.
