Fluvastatin Tablets and Capsules (Lescol)
Comprehensive guide to Fluvastatin (Lescol): uses, dosage, side effects, and key precautions for managing high cholesterol effectively.
Fluvastatin, commonly known by the brand name Lescol, is a medication belonging to the statin class of drugs. It works by inhibiting HMG-CoA reductase, an enzyme crucial for cholesterol production in the liver, thereby reducing low-density lipoprotein (LDL) cholesterol levels, modestly lowering triglycerides, and slightly increasing high-density lipoprotein (HDL) cholesterol. This helps prevent atherosclerosis, where fats clog blood vessels, reducing the risk of heart attacks, strokes, and other cardiovascular events.
About fluvastatin tablets and capsules
Fluvastatin is available in immediate-release capsules and extended-release tablets, typically in strengths of 20 mg, 40 mg, and 80 mg. It is prescribed as an adjunct to diet and lifestyle changes for adults with primary hypercholesterolemia or mixed dyslipidemia, and in those with clinical evidence of coronary heart disease (CHD) to slow atherosclerosis progression. Unlike some statins, fluvastatin is taken once daily in the evening for optimal effect, as cholesterol synthesis peaks at night.
Lescol is particularly useful for patients who need low-to-moderate intensity statin therapy. It is often chosen for its affordability as a generic and relatively favorable side effect profile compared to higher-intensity statins, though all statins carry similar risks.
Before taking fluvastatin tablets and capsules
Allergy
Do not take fluvastatin if you have had a severe allergic reaction to it or any statin in the past. Symptoms of allergy include rash, itching, swelling of the face, lips, tongue, or throat, trouble breathing, or anaphylaxis. Rare cases of Stevens-Johnson Syndrome (SJS), a severe skin reaction, have been reported.
Pregnancy and breastfeeding
Fluvastatin is contraindicated during pregnancy due to potential fetal harm, as statins can cause birth defects. Women of childbearing potential should use effective contraception. It is also not recommended while breastfeeding, as it passes into breast milk.
Babies and children
Fluvastatin is not approved for use in children under 10 years old. For adolescents 10-17 with familial hypercholesterolemia, it may be used under specialist supervision, but safety data is limited.
Taking other medicines and herbal medicines
Fluvastatin interacts with numerous drugs, increasing risks of muscle damage (myopathy) or rhabdomyolysis. Key interactions include:
- CYP3A4 inhibitors like itraconazole, ketoconazole, HIV protease inhibitors, erythromycin, clarithromycin, and telithromycin.
- Other lipid-lowering drugs such as gemfibrozil (contraindicated), other fibrates, or niacin.
- Cyclosporine or tacrolimus, which can increase fluvastatin levels significantly.
- Warfarin, requiring INR monitoring.
- Digoxin, colchicine, or fusidic acid.
Herbal remedies like St. John’s wort may reduce efficacy. Always inform your doctor of all medications.
Conditions to look out for
Avoid fluvastatin if you have active liver disease, unexplained persistent elevations in liver enzymes, or decompensated cirrhosis. Use cautiously with history of liver disease, kidney impairment, hypothyroidism, neuromuscular disorders like myasthenia gravis, heavy alcohol use, or risk factors for myopathy (age >65, female, low BMI).
How and when to take fluvastatin tablets and capsules
Dosage
The usual starting dose is 20-40 mg once daily at bedtime for capsules or 80 mg once daily for extended-release tablets. Maximum dose is 40 mg twice daily for capsules or 80 mg daily for tablets. Dosage adjustments are made based on LDL goals, typically after 4 weeks.
| Patient Group | Starting Dose | Max Dose |
|---|---|---|
| Primary hypercholesterolemia | 20-40 mg once daily | 40 mg twice daily (capsules) or 80 mg (XL) |
| With cyclosporine | 20 mg once daily | 40 mg once daily |
| Children 10-17 years | 20 mg once daily | 40 mg once daily |
How to take it
Swallow capsules or tablets whole with water, with or without food. Extended-release tablets must not be crushed or chewed. If a dose is missed, take it as soon as remembered unless near the next dose; do not double up.
