Hello and welcome to MedHelp's forums. Thanks for the question. Yes, niacin has been added to certain medications particularly in the statin class. This article explains it nicely https://www.mayoclinic.org/diseases-conditions/high-blood-cholesterol/in-depth/niacin/art-20046208. The thought behind adding niacin was that it would help raise HDL levels even more than the statin drug alone. However, just recently, studies indicate that this potential benefit really isn't being seen in patient populations. Good question, thank you for asking it. And remember to follow up with your doctor.
