Hi, I need to know how to replace a daily regime of otrivin efficiently. I had a nose surgery in 2008 and since then my nose is permanently blocked. I was told to use otrivin to unblock it. The problem is, I have been using it daily for since last 1 year , 4 times a day. I know it is harmful to do so, but I really can't breathe without it. Without it I can't function either. I tried a few things, such as boiling water once but nothing is as effective as otrivin. Please advise on the possible replacements.
