How long can I keep a multidosage bottle after opening? In correct storage conditions, it will last approximately 6 months after opening. It is best to store it away from light or a heat source. wynns20212021-08-12T06:43:21+00:00August 12, 2021|0 Comments Leave A Comment Cancel replyComment Save my name, email, and website in this browser for the next time I comment.
