high cholesterol
"Niaspan was prescribed by my doctor for Lipid Protein little a.  My cholestrol was about 400+.  I took one dose (500mg) at night and within 30 minutes I was in emergency room with anaphylactic shock. I don't remember much of anything till I woke up the next morning and was told how bad it almost was for me.  I take 8 statins to maintain a cholesterol of 200."
