Indications & Uses
Ridel ER is indicated for:
Pharmacology
Niacin is a preparation of nicotinic acid. It lowers VLDL, LDL, total cholesterol and triglyceride levels and raises HDL levels, and this effect is well proven. Because of this, niacin has been prescribed for cardiovascular disease, particularly the hyperlipidemias.
Dosage Reference
Reference Information Only
Dosages shown are general references from official sources. Always consult your doctor or pharmacist for personalized dosing.
Adults:
Start with one 500 mg tablet at bedtime, and keep to that dose for 1 to 4 weeks.
For maintenance, don't raise the daily dose by more than 500 mg in any 4 week period. The recommended maintenance dose is 1000 mg (two tablets) to 2000 mg (4 tablets) once daily at bedtime. Doses above 2000 mg a day are not recommended. The dose may also be different if the registered physician directs it.
Side Effects
Niacin is generally well tolerated, and the side effects seen have been mild and short-lived. The most frequent ones were flushing, itching (pruritus), nausea and GI upset, jaundice, hypotension, tachycardia, raised blood glucose and uric acid levels in serum, and myalgia.
Cautions & Contraindications
Warnings & Precautions
Before starting Niacin, try to control the hyperlipidemia with a suitable diet, exercise, and weight reduction in obese patients, and treat any other underlying medical problems. Patients with a past history of jaundice, hepatobiliary disease, or peptic ulcer should be watched closely during Niacin therapy. Liver function tests and blood glucose should be checked often, to confirm the medicine is causing no adverse effects on these organ systems. Diabetic patients may have a dose-related rise in glucose intolerance, and the clinical significance of this is unclear. Diabetic or potentially diabetic patients should be observed closely, because the diet and/or hypoglycemic therapy may need adjusting. Caution should also be used in patients with unstable angina or in the acute phase of MI, particularly when they are also receiving vasoactive drugs such as nitrates, calcium channel blockers or adrenergic blocking agents. Elevated uric acid levels have occurred with Niacin therapy, so use it with caution in patients predisposed to gout. Niacin has been associated with small but statistically significant, dose-related reductions in platelet count and increases in prothrombin time. Caution should be observed when it is given together with anticoagulants, and prothrombin time and platelet counts should be monitored closely in these patients. Small but statistically significant, dose-related reductions in phosphorus levels have also been linked to Niacin (mean of -13% with 2000 mg). So phosphorus levels should be monitored periodically in patients at risk.
Contraindications
Niacin (nicotinic acid) should not be given to anyone who is known to be hypersensitive to niacin or to any other component of the medicine. It is also contraindicated in people with significant or unexplained liver dysfunction, active peptic ulcer disease or arterial bleeding.
Pregnancy & Breastfeeding
Niacin shouldn't be used in pregnancy or while breastfeeding, because there isn't enough information about it.
⚠️ Talk to your doctor before taking any medicine during pregnancy or while breastfeeding.
Overdose
If someone takes too much Nicotinic Acid (Niacin), supportive measures should be started. The symptoms can include nausea, dizziness, itching, vomiting, upset stomach and flushing.
⚠️ In an emergency call 999 or go to the nearest hospital emergency department.
