Shelf life of minoxidil after bottle is opened?

[sammy]

Hi All,

I have a opened bottle of dr lee 5% minoxidil with retin-a that has been sitting there for about 3 months can i still use it or should i buy some new bottles?

cheers

depends by how you have preserved it
if it was in a dark place, far from light, you can use it without problems

Once you crack open the minoxidil bottle, and expose the contents to air, it immediately starts oxidizing, unless you vacuum it back shut. But I'll bet an unopened bottle of minoxidil will last long after the expiration date.
