About 12 days ago my order of letrozole arrived and I started using it. (I switched to letro from aromasin as I was getting some gyno and just didn't feel good on the Aro, things have improved since switching).
It is liquid research grade. Over the last week or so it looks like some white substance is coming out of solution and settling on the bottom of the vial. When I twirl it around it doesn't go back into solution. I'm worried and wondering if the drug itself is separating from the solution and its becoming less concentrated.
Last night I finally decided to try stirring it up with a paper clip, it seemed to maybe help a little but not much changed. I was keeping it in my dresser drawer which is next to a window I always have open ( I'm a furnace, I burn up even in winter), but I moved it into the bathroom since its a warmer environment I thought that might make a difference, but the progression seems to be the same.
Has anyone experience this before or is it common? Is there anything I should do about it and how worried should I be? THanks for any help you can give!!
