Niacin for primary and secondary prevention of cardiovascular events. Cochrane Database of Systematic Reviews. Accessed Aug. Micromedex 2. A shared characteristic among niacin studies reporting low discontinuation rates is the patient education procedures employed prior to study initiation.

Support for this comes from a survey of patients in routine clinical practice who were prescribed niacin and reported a high rate of discontinuation; less than half of niacin users reported being advised by their physician to take aspirin to avoid flushing. The onset and intensity of the flush is directly related to the niacin absorption rate and the consequent rate of elevation of blood niacin levels; once a constant blood niacin level is reached the flush starts to abate. The good news is that there are several ways to reduce the initial intensity of the flush:.

Immediate-release niacin should be administered in divided doses, after meals, and doses should be gradually increased. If you are using time-release niacin — make sure it is was-matrix niacin. Start taking mg 3 times per day, and build up the dose to mg times per day. Always take it after meals. Extended-release niacin is recommended to be taken at bedtime, after the last daily meal.

Several studies shows that aspirin attenuates niacin flushing. Take immediate-release niacin after meals, especially a high-fat meal, as that will slow down its absorption and thus reduce the flush intensity. Prescription extended-released niacin Niaspan , which is ingested once daily, should be taken after the last daily meal. If you take any time-release niacin that is not wax-matrix — such as Slo-Niacin or Niaspan - is it best to take if some 40 min after meals.

The reason is that the release mechanism of Slo-Niacin is degraded by peristaltic activity in the gut. Waiting a little bit after a meal will let the gut settle and allow for the time-release complex to work as it is supped to.

Most people don't know that continued niacin supplementation leads to development of tolerance to the flush. Flush tolerance is due in part to smaller increases of prostaglandin D2 production after long-term regular niacin ingestion. Hence, with niacin supplementation one has to stick to it! Several studies have shown that many of the people who appear to be intolerant of niacin, primarily because of the flush, are often just more sensitive to niacin and do well on a reduced dose.

You may still derive substantial health benefits with a lower dose. With immediate-release niacin, start taking mg twice daily for the first week, then double the daily dose each week until the target dose is reached, ideally to mg per day. With time-release niacin — ideally wax-matrix niacin — start taking mg 3 times per day, and build up the dose to mg times per day.

Spread out intake over the day and take some 40 min after meals to dampen the niacin flush. If the flush makes you uncomfortable, taking mg aspirin about 30 minutes prior to niacin reduces the flushing intensity. Try taking the aspiring before meals, and then the niacin after meals.

Stick to it! With regular daily niacin supplementation, tolerance develops to the flush. Over time, the flush sensation can disappear completely in people who diligently keep taking niacin every day. The reason it has not been getting the attention it deserves in the medical community and among health conscious people, is the flush. While the niacin flush may be uncomfortable, it is not dangerous; it is a natural reaction to high-dose niacin.
