Aaron, I take Kuvan — I only take 9 pills — It depends on your height and weight though. I used to have to take 120 pills, so 9 pills to me is a piece of cake…. 18 would be too! I know some dietitians suggest to their patients take pills split in the morning and night if they are having trouble doing it all in one sitting. Also, I do not drinking a huge amount of water to swallow the pills. In general, I do drink a lot of water — but not when I take Kuvan….
If you have any other questions – feel free to message me.
