What is Niacin?
Niacin, one of the oldest drugs used to treat dyslipidemia, favorably affects virtually all lipid parameters. Niacin is a water-soluble B-complex vitamin that functions as a vitamin only after its conversion to NAD or NADP, in which it occurs as an amide. Niacin also is the only lipid-lowering drug that reduces Lp(a) levels significantly.

How does Niacin work?
- Nicotinic acid inhibits the hepatic production of VLDL and consequently its metabolite LDL.
- Nicotinic acid affects HDL metabolism by reducing the transfer of cholesterol from HDL to VLDL and by delaying hepatic HDL clearance.
How to take Niacin?
- Crystalline Niacin (immediate-release or regular) refers to niacin tablets that dissolve quickly after ingestion.
- Sustained-release Niacin refers to preparations that continuously release niacin for 6-8 hours after ingestion.
- Take Niacin with a full glass of cold or cool water.
- Swallow the tablets.
- The hypolipidemic effects of Niacin require larger doses than are required for its vitamin effects.

Common Dosage for Niacin
- The daily dose should not exceed 20 mg.
- Regular or crystalline Niacin in doses of 2-6 g/day reduces triglycerides by 35-50%; the maximal effect occurs within 4-7 days.
- Reductions of 25% in LDL-C levels are possible with doses of 4.5-6 g/day, but 3-6 weeks are required for the maximal effect.
- For lipid-lowering effects, nicotinic acid is given in much higher doses than are needed as a vitamin.
- Crystalline Niacin tablets are available over the counter (from 50- to 500-mg tablets).
- To minimize the flushing and pruritus, it is best to start with a low dose (100 mg twice daily taken after breakfast and supper). The dose may be increased stepwise every 7 days by 100-200 mg to a total daily dose of 1.5-2 g.
- Triple therapy with resins, Niacin, and statins can reduce LDL-C by up to 70%.
When to avoid Niacin?
- Combination therapy (statin plus niacin or statin plus fibrate) may be required, but caution is necessary with these combinations to avoid myopathy.
- Severe hepatotoxicity is more likely to occur when patients take more than 2 g of sustained-release, over-the-counter preparations. Affected patients experience flu-like fatigue and weakness.
- In patients with diabetes mellitus, Niacin should be used cautiously because niacin-induced insulin resistance can cause severe hyperglycemia.
- Niacin also elevates uric acid levels and may reactivate gout. A history of gout is a relative contraindication for niacin use.
Precautions when taking Niacin?
- Do not crush, chew, break, or open an extended-release tablet or capsule.
- Flushing recurs if only one or two doses are missed, and the flushing is more likely to occur when Niacin is consumed with hot beverages (coffee, tea) or with ethanol-containing beverages.
- Patients with any history of peptic ulcer disease should not take Niacin because it can reactivate ulcer disease.
- If Niacin is prescribed for patients with known or suspected diabetes, blood glucose levels should be monitored at least weekly until proven to be stable.
