someone told me that the 7.5 is potassium hydrochloride or something like that. Somethign that they add to the phen. Not sure if I believe them......you would have to askt he pharmacist I guess.

My dr started me on 30 and said if that doesnt' work he'll put me on 37.5. So the 37.5 is stronger....but you probably want to be on the smallest amount that's effective.

The difference is you CAN"T split the 30mg because it is timed release.
the 37.5 you can split in half. I started on half a 37.5 a day, then after a week, went to 1/2 am, 1/2 pm after three weeks said I could go to just one whole 37.5. I prefer taking 1/2 twice a day it works better for me with better conttrol......all the info I just gave you is what my Doc told me. but you can check it out on the internet.
