Niacin, in conjunction with a suitable diet and exercise regimen, is employed to aid in the reduction of “bad” cholesterol and fats (LDL, triglycerides) while simultaneously elevating “good” cholesterol (HDL) levels within the bloodstream. Niacin, also recognized as vitamin B-3 (nicotinic acid), belongs to the family of B-complex vitamins. It can be administered alone or in conjunction with other medications. The objective of diminishing “bad” cholesterol and triglycerides and enhancing “good” cholesterol is to lower the risks of stroke and heart attacks. The reduction of fats may also contribute to mitigating the likelihood of pancreas issues (pancreatitis) in individuals predisposed to such concerns.

Uses and Dosage

Administer this medication orally with a low-fat meal or snack, following your doctor’s instructions, usually before bedtime. Consuming niacin on an empty stomach can intensify side effects like flushing and stomach upset. Swallow the tablets whole; do not crush or chew them, as this might lead to a sudden release of the entire dosage, raising the risk of side effects.

Niacin is accessible in various formulations, such as immediate and sustained release. Avoid switching between different strengths, brands, or forms of niacin to avert the possibility of severe liver issues.

The prescribed dosage is contingent upon your medical condition and response to treatment. To mitigate side effects, your doctor may advise commencing with a low dose and gradually increasing it. Even if you are transitioning from another niacin product, the dose should be elevated slowly. Adhere rigorously to your doctor’s directives.

If you are also taking particular other cholesterol-lowering medications like bile acid-binding resins (for example, cholestyramine or colestipol), ingest niacin at least 4-6 hours prior to or after these medications. Such products might interact with niacin, hindering complete absorption. Continue taking other cholesterol-lowering medications as prescribed by your doctor.

To reduce the likelihood of flushing, avoid alcohol, hot beverages, and spicy foods around the time of niacin intake. Consuming an uncoated (non-enteric coated) 325-milligram aspirin or a nonsteroidal anti-inflammatory drug (such as ibuprofen, 200 milligrams) 30 minutes before niacin intake could help prevent flushing. Consult your doctor to determine if this approach suits you.

Maintain regular usage of this medication to attain optimal benefits. Establish a consistent routine by taking it at the same time daily. Even if you feel well, continue using this medication. Many individuals with elevated cholesterol levels might not experience noticeable symptoms.

Do not discontinue this medication without consulting your doctor. Stopping niacin might necessitate reverting to your initial dose and incrementally increasing it once more. Seek guidance from your doctor or pharmacist if you haven’t taken the medication for an extended period (over 7 days) on how to restart your dosage.

Adhering to your doctor’s guidance on diet and exercise remains highly important.
