The absorption rate for this antifungal medication is poor, and it is excreted through a fecal method where the drug remains unchanged. After taking Nystatin, signs of improvement may occur within 24 to 72 hours.
For patients taking the dry powder form of Nystatin:
Here are the instructions for using the dry powder:
1/8 teaspoon of the dry powder should be immediately added to 4 ounces of water then mix well by making sure that they are stirred properly together.
Once the dry powder and the water are mixed properly, take medicine in divided doses such that the whole amount, which is around 4oz, is taken in several portions.
As you take each portion, hold or swish it around in your mouth for as long as possible, then gargle and swallow. Make sure that you use up all the liquid to complete a full dosage.
