For High Cholesterol "After two years of taking 1 g per day, I developed a rash; at first with itch, then it seemed to be like a very bad sunburn. Areas affected included ankles, legs, thighs, belly, and biceps. A trip to the doctor, I stopped taking and went home to lots of cool showers. After a week of walking around the house naked (just the touch of clothes caused burning and itching), the rash has begun to subside."

Niacin for High Cholesterol "After a few days of taking this medication, I was awoken in the middle of the night with the warm red rash on my abdomen, which was also extremely itchy. After 3 consecutive nights of the same reaction, I discontinued the medicine and called my doctor. He changed my prescription to another cholesterol medicine."

For Niacin Deficiency "I had a horrible reaction to it. My skin felt as though it was burning from the inside, I was covered in hives, my breathing became very weird, and I had chills — which resulted in shaking uncontrollably. Ended up going to the hospital."

For High Cholesterol "Started taking Niacin-B3 500 mg a month ago at bedtime. About 3 weeks into it, I would wake up with stomach pains with the feeling of vomiting, I also had loose bowels, legs hurt, dry skin, and itchy rash. Stopped taking the meds instantly and called my doctor. Still suffering with rash and itch."

Niacin for High Cholesterol "I had never taken a medication that had me in fear for my life like Niacin. The pain, redness, flushing, rash, and drooping of the face was horrible only after the second pill. It is a very worrisome medication, I would never take it again."
