Niacin Overdose

I have been taking large doses of niacin lately.I read that can lower your cholesterol levels.Yesterday someone i took 3,000 mg.Does not know if this is harmful or dangerous? What happens if you overdose of niacin?

Yes, too much niacin is dangerous. Last month, I took a doctor prescribed niacin, 500 mg, and after about three weeks, the account I had a severe reaction to it. I became so hot that I thought I literally on fire, I had shortness of breath, lower blood pressure and I fainted. When my husband made me aware of passing my blood pressure was 69/47. Please talk to your doctor before taking niacin and 3,000 mg sounds way too much. Oh yes and the drug has been prescribed for cholesterol. The ER doctor told me not to take more.

Beware of ur self
