high cholesterol
"I have taken Niaspan 2000 mg for several years now.  It has had great success in raising my HDL and keeping my triglycerides low.  For years, I had minimal problems with flushing.  But now recently, I have had a number of episodes where I have woken up in the middle of the night with almost unbearable itching/burning skin.  I took a break from the Niaspan for a couple nights, and then when I tried it again the itching was worse.  I am going to have to discontinue this and consult with my doctor about what to do next to keep my numbers good."
