I finally got a rx filled today with pure nystatin powder. Its supposed to be 30 mil units, but only weighs 5 grams on my scale. I coulda swore i've read that nystatin only contains 4.4 mil units per gram. Could it be different for different brands? Whats the best way to dose this stuff out anyways? Im only up to 1.5 mil units per day at the moment.
Also, how long can the stuff be out of the fridge before losing effectiveness? Is it worth mail ordering if it spends a week out of the fridge?
