In the placebo-controlled clinical trials database of 402 patients (age range 21-75 years, 33% women, 89% Caucasians, 7% Blacks, 3% Hispanics, 1% Asians) with a median treatment duration of 16 weeks, 16% of patients on NIASPAN and 4% of patients on placebo discontinued due to adverse reactions. The most common adverse reactions in the group of patients treated with NIASPAN that led to treatment discontinuation and occurred at a rate greater than placebo were flushing (6% vs. 0%), rash (2% vs. 0%), diarrhea (2% vs. 0%), nausea (1% vs. 0%), and vomiting (1% vs. 0%). The most commonly reported adverse reactions (incidence > 5% and greater than placebo) in the NIASPAN controlled clinical trial database of 402 patients were flushing, diarrhea, nausea, vomiting, increased cough and pruritus.

Hypersensitivity reactions, including anaphylaxis, angioedema, urticaria, flushing, dyspnea, tongue edema, larynx edema, face edema, peripheral edema, laryngismus, and vesiculobullous rash; maculopapular rash; dry skin; tachycardia; palpitations; atrial fibrillation ; other cardiac arrhythmias; syncope; hypotension ; postural hypotension ; blurred vision; macular edema; peptic ulcers; eructation ; flatulence ; hepatitis ; jaundice ; decreased glucose tolerance; gout ; myalgia ; myopathy ; dizziness; insomnia; asthenia ; nervousness; paresthesia ; dyspnea; sweating; burning sensation/skin burning sensation; skin discoloration, and migraine.

In general, the incidence of adverse events was higher in women compared to men.

Because clinical studies are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical studies of another drug and may not reflect the rates observed in practice.

Niaspan (niacin) is a B-complex vitamin. Niaspan is available in generic form as niacin. Niaspan is used along with dietary changes (restriction of cholesterol and fat intake) to reduce the amount of cholesterol and certain fatty substances in the blood. It is also used to prevent and treat pellagra, also known as niacin deficiency, a disease caused by inadequate diet and other medical problems. Common side effects may include: headache, blurred vision, nausea, vomiting, or diarrhea.

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat.

Chemistry : Elevations in serum transaminases, LDH, fasting glucose, uric acid, total bilirubin, amylase and creatine kinase, and reduction in phosphorus.

In the placebo-controlled clinical trials, flushing episodes (i.e., warmth, redness, itching and/or tingling) were the most common treatment-emergent adverse reactions (reported by as many as 88% of patients) for NIASPAN. Spontaneous reports suggest that flushing may also be accompanied by symptoms of dizziness, tachycardia, palpitations, shortness of breath, sweating, burning sensation/skin burning sensation, chills, and/or edema, which in rare cases may lead to syncope. In pivotal studies, 6% (14/245) of NIASPAN patients discontinued due to flushing. In comparisons of immediate-release (IR) niacin and NIASPAN, although the proportion of patients who flushed was similar, fewer flushing episodes were reported by patients who received NIASPAN. Following 4 weeks of maintenance therapy at daily doses of 1500 mg, the incidence of flushing over the 4-week period averaged 8.6 events per patient for IR niacin versus 1.9 following NIASPAN.

Niaspan is available as a tablet or an extended-release tablet to be taken orally. It should be taken at bedtime, after a low-fat snack. Doses should be individualized according to patient response. Therapy with Niaspan must be initiated at 500 mg at night to reduce the incidence and severity of side effects that may occur during early treatment. Caution should be used when Niaspan is used in patients with unstable angina or in the acute phase of a myocardial infarction (MI), especially when such patients are also receiving vasoactive drugs, such as nitrates, calcium channel blockers, or adrenergic blocking agents. If patients become pregnant, they should stop taking Niaspan and consult with their doctor. Women who are breastfeeding should not use Niaspan.

Because the below reactions are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

The following additional adverse reactions have been identified during post-approval use of NIASPAN:

Tips to keep it under control.

In AIM-HIGH involving 3414 patients (mean age of 64 years, 15% women, 92% Caucasians, 34% with diabetes mellitus) with stable, previously diagnosed cardiovascular disease, all patients received simvastatin, 40 to 80 mg per day, plus ezetimibe 10 mg per day if needed, to maintain an LDL -C level of 40-80 mg/dL, and were randomized to receive NIASPAN mg/day (n=1718) or matching placebo (IR Niacin, 100-150 mg, n=1696). The incidence of the adverse reactions of “ blood glucose increased” (6.4% vs. 4.5%) and “ diabetes mellitus ” (3.6% vs. 2.2%) was significantly higher in the simvastatin plus NIASPAN group as compared to the simvastatin plus placebo group. There were 5 cases of rhabdomyolysis reported, 4 (0.2%) in the simvastatin plus NIASPAN group and one ( < 0.1%) in the simvastatin plus placebo group.
