My feeling is this the company makes them so they know exactly how the pills are designed what their release mechanisms are like etc. They spent billions developing this stuff where the pharm and np spend five minutes signing their name to a script. If the company doesn't put info like that into its product sheet they will be sued where as there is no penalty for your np or pharm to suggest you should be on whole pills when its not necessary. If I were to trust anyone I'd trust the company but at the same time you're on 40mg now so problem solved I wouldn't worry about it at all right? I just didn't want you to feel like you were doing something wrong when you were cutting the pills when you're actually getting bad advice...I would however consider a different care provider. Once I got a primary care provider who wrote me a script for something available over the counter I was so embarrassed when the pharmacist directed me to aisle 6 you know...I never went back to that doc again...
