What is the shelf life of this product once a bottle has been opened and used?

the box has an expiration date. use of the product after expiration is not known. i would suspectit would last for several weeks or longer. when your nose does not burn when you use it, i would toss it.

The bottle I received says 8/14 and I received it a few months ago so I would say 1 year

If you haven't opened the bottle then it will last for a long time. I have had no problems with being unused for long periods of time.

I've only been using it once a day for about 1 1/2 weeks, so I'm not sure how long it will last. I just looked at the bottle though and it looks like I haven't used it at all. I suspect it will last for awhile. I should mention that I don't think there are preservatives in the product, so it may spoil before I finish the bottle. I may keep it in the refrigerator when it gets warmer to try to extend shelf life.

I don't currently have a bottle, but I'd assume it'd be good for at least 1-2 years before the shelf date, then likely a few months after.

My understanding is that the product has a two-year shelf life if not opened or used.

Over a year on the use by date on the bottle, I refrigerate it after opening it and generally use it within 6 to 8 months. Always stays fresh and the taste is always the same.

The unopened bottle I have says it is good until October 2015. I've been using this great product for about six years.

I am uncertain of the shelf life. We used one and did not open the other for at least two weeks and it was still fresh.

The shelf life is at least two years for this product. The bottle I have is good until the end of 2014 and I have had it for a month or two.

yes, the bottle says you need to refrigerate it after you open it and it has a shelf life of 6 months after that I do believe.

I do not know the shelf life but after opening I have just kept it on cabinet the shelf, that is, I did not refrigerate it.

The shelf life would be 1 year, once the product is open it is good for 5 days in the refrigerator..

4 Years is the shelf life. It is unaffected by opening it and using some. If it takes you 4 years to use this product, you clearly do not go outside enough. Some people use it as a back up and I would suggest using it in that last year and replacing it.

The expiration date is on the bottle, but the instructions say, "Discard opened bottle after 30 days".

I'm sorry, I bought this a long time ago. I don't remember the shelf life. It was well sealed, so I doubt additional sealing would help.
