Dr. Hibberd's answer:

 

You should get your doctor's permission to stop the niacin and review other options to replace it, probably with a statin.

 

Current prevention guidelines now recommend against niacin because of potential side effects (including myopathy, drug-drug interactions, negative glucose tolerance).

We generally emphasize dietary management, exercise, correction of underlying cardiovascular risk factors, statin use, and/or fish oil therapy as primary strategies to reduce cardiovascular disease risks.
