What should you know about niacin for high cholesterol?

Niacin, also called vitamin B3, is available in prescription and non-prescription forms. It can affect several types of blood lipid, but a supplement is not automatically a suitable cholesterol treatment. Flushing, warmth, itching, stomach upset, and changes in liver tests can occur. The choice depends on your lipid pattern, medical history, other medicines, and cardiovascular risk. A cholesterol test helps establish the starting picture and monitor a plan.

Do not start high-dose niacin without medical advice, and do not substitute it for a prescribed statin or another treatment. Tell the clinician about liver disease, diabetes, gout, ulcers, alcohol use, and every medicine or supplement you take. Nutrition counselling can support changes to meals, activity, weight, and smoking. Take only the formulation and dose recommended; extended-release and immediate-release products are not interchangeable. Keep monitoring appointments even if you feel well.

Contact a clinician promptly for severe or persistent abdominal pain, yellowing of the skin or eyes, unusually dark urine, profound weakness, or unexplained muscle pain. Seek emergency help for chest pressure, sudden weakness on one side, trouble speaking, or severe breathlessness. These symptoms may signal a separate urgent problem and should not be explained away as a medicine effect.

Ask which lipid result the treatment is intended to change, whether a statin or lifestyle plan is more appropriate, which blood tests are needed, and how flushing or other effects should be handled. Check whether your medicines can interact with niacin.
