I am not sure about home remedies. I know my ENT said would have to have antibiotics if it came up.

The key to not developing thrush I was told by my ENT and PCP was prevention. Were you told to wash out your mouth and gargle after each time you used the inhaler? Or was the issue with thrush from a sinus spray with steroids?

I guess you could still get the steroids down into your throat from a nasal spray but was not given that would cause it. I know I take Xhance a steroid for my sinuses and I was not instructed to gargle afterward.

However I also use Mexiline (spell) a steroid inhaler for bronchial irritation. And with that was told to gargle and wash mouth out immediately after using the inhaler every time.

Don't know if this helped but my experience with this.
