The symptoms you have described could be the signs of an allergic reaction and you should get medical assistance immediately.
from http://www.drugs.com/mtm/niaspan-er.html
If you experience any of the following serious side effects, stop taking nicotinic acid and seek emergency medical attention:
*an allergic reaction (difficulty breathing; closing of your throat; swelling of your lips, tongue, or face; or hives);

Thank you for your answer to my question but I am afraid to take the medicine. If you have this reaction how long do you have to get to the ER before you actully stop breathing. This is what I am afraid of.
