My, soon to be, former doctor told me that over-the-counter Slo-Niacin damages the liver while Niaspan does not but he cited no research. I have read, again without citing research, that any kind of extended release tablet is harmful. Any comments? ## Well Niaspam is just a name brand for a pill that is just Niacin, so that really doesn't make sense.
