talk to the pharmacist since i have no idea what pills your mother is taking. some specially-coated pills have a sustained release "matrix" that does not dissolve but the active ingredient of the drug is released. do not crush any pill until you discuss this issue with the pharmacist.
pills nor dissolving. some medications doesn't dissolve and shows up in my mother's stool. is there any dangers crushing the pills and mixing it with something like applesauce?
