Nicotinic Acid — Uses, Dosage, Side Effects & Safety

Drug class: Antihyperlipidemic (Lipid-lowering agent); Vitamin (Vitamin B3, Niacin)

Overview

Nicotinic Acid, also known as niacin or vitamin B3, is a medication and dietary supplement used to lower cholesterol and triglyceride levels in the blood. It is often prescribed to help reduce the risk of heart disease, especially in people with high cholesterol who cannot control their levels with diet and exercise alone. Nicotinic Acid works by decreasing the amount of 'bad' cholesterol (LDL) and triglycerides while increasing 'good' cholesterol (HDL). It does this by affecting the way your liver produces certain fats. This medication may be used alone or with other cholesterol-lowering drugs. Key points for patients: Nicotinic Acid can cause flushing (a warm, red feeling in the face and neck), especially when you first start taking it. Taking it with food or at bedtime may help reduce this effect. Always follow your healthcare provider's instructions and do not stop taking Nicotinic Acid without consulting your doctor.

Frequently Asked Questions about Nicotinic Acid

What is Nicotinic Acid used for?

Nicotinic Acid is primarily used to lower cholesterol and triglyceride levels, and to increase HDL ('good') cholesterol. It is also used as a vitamin supplement to prevent or treat niacin deficiency.

How can I reduce flushing caused by Nicotinic Acid?

Taking Nicotinic Acid with food, at bedtime, or using an extended-release formulation can help reduce flushing. Avoiding alcohol and hot drinks around the time of dosing may also help. Some people take aspirin 30 minutes before the dose, but consult your doctor before doing so.

Is Nicotinic Acid safe for people with diabetes?

Nicotinic Acid can raise blood sugar levels and should be used with caution in people with diabetes. Blood glucose should be monitored closely, and dose adjustments may be necessary.

Can I take Nicotinic Acid with statins?

Nicotinic Acid can be combined with statins for additional cholesterol lowering, but this combination increases the risk of muscle toxicity (myopathy/rhabdomyolysis). Your doctor will monitor you closely if both are prescribed.

What should I do if I experience severe side effects?

Stop taking Nicotinic Acid and seek immediate medical attention if you experience severe abdominal pain, yellowing of the skin or eyes, dark urine, muscle pain with weakness, or signs of an allergic reaction.

Is Nicotinic Acid the same as niacinamide?

No, while both are forms of vitamin B3, only Nicotinic Acid (niacin) is effective for lowering cholesterol. Niacinamide does not have lipid-lowering properties.

Can pregnant or breastfeeding women take Nicotinic Acid?

Nicotinic Acid should only be used during pregnancy or breastfeeding if clearly needed and prescribed by a healthcare provider. High doses for cholesterol lowering are generally not recommended in these populations.
