The bottle of CD&T says to use the entire contents when first opened, but doesn't it last for the booster shot in a month? I have always saved the bottle and used the same stuff for the booster shot a month after first using it and then I throw it away. I just noticed the warning, "use entire contents when first opened", today . Have I just been really lucky? Should I use new bottles every time from now on? Or do you think it's it okay to use it twice?
