Hi , and thanks for posting this question - it's a good one!!
What works for me (and my family), is the Aquafor product line. It was recommended to me by our ENT physician many years ago. We have been successful using it ever since.
I would suggest folks check with their doctor before using any(prescription or over-the-counter), medications. It is the most prudent approach to starting new products.
Warm regards,
