Believe it or not, I am taking 5 Niacin tablets in the morning and 5 at night for high trigylcerides. I can't remember the strength, but this is what is oredered by my doctor. In addition to that of course I have to take a statin and Tricor. Good news is that Tricor will have a generic out in May. I was also told by my pharmicist that Plavix has a generic coming out in July. Ask your pharmicist if there is a generic of Niaspan due out any time soon.
And as Flycaster has stated, with the Niacin there is a flushing feeling also. It only bothered me if I didn't take an aspirin just before taking the niacin. My doctor told me about that. Ally
I assume you have a cholesterol issue. Why not ask your doctor for a prescription for a statin medicine? You can get the drug for $4.00 a month or less, and it's much less invasive than Niaspan, in my opinion. I tried Niaspan years ago, it wasn't effective, and I would get a huge 'blushing' feeling, my face would flush and I would be miserable. Statin drugs are very safe and in my opinion, very effective.
