Recently there has been a change in PG 600. The product now requires refrigeration for storage and has extended the expiration date to three years. My quick read on this situation is that the product hasn’t changed but by requiring refrigeration they were able to extend product life an additional year. They no longer make singles and I am often asked what do I do when I have part of a multiple dose left. The answer is simple, freeze it and thaw it when you need it next time. We will ship Pg 600 without refrigeration. However, it is important to refrigerate on arrival.
