It depends upon the type of budesonide. Extended release is granulares,not a powder. Does the label say extended release? It may be abbreviated..
Swallow the extended-release capsule and extended-release tablet whole. Do not break, crush, chew, or open it.
If you cannot swallow the extended-release capsule, you may open it and mix the granules into a tablespoonful of applesauce (not hot). Swallow the mixture whole. Do not chew or crush the granules. Take the mixture within 30 minutes. Drink a glass (8 ounces) of water right after.
Swallow the delayed-release capsule whole. Do not open, crush, or chew it. Take this medicine in the morning, at least 1 hour before a meal.

I know the instructions seem contradictory since one part swallow whole but also says mix with applesauce.
When I uses extended release capsules I go the 3mg human capsules and divided it up into 1/3s and put other meds in a capsule too.
