Rosuvastatin

Rosuvastatin is a statin (hmg-coa reductase inhibitor) — lipid-lowering agent medicine available in Bangladesh under many brand names. Below are its uses, dosage, side effects and precautions — and all brands with their current prices.

Rosuvastatin is prescribed for:

• High LDL cholesterol — including inherited (familial) hypercholesterolaemia.
• Mixed dyslipidaemia — raised cholesterol with raised triglycerides.
• Prevention of cardiovascular events — reducing the risk of heart attack, stroke and the need for stenting in high-risk people, even with near-normal cholesterol.
• After heart attack, stroke or angioplasty — usually continued lifelong.
• Slowing atherosclerosis — progression of artery-wall plaque.

Your doctor selects the dose according to your risk level, kidney function and other medicines.

The dose of Rosuvastatin is decided by your doctor. Treatment commonly starts at 5–10 mg once daily and may be adjusted after 4 weeks based on lipid reports; the usual range is 5–20 mg daily, with 40 mg reserved for severe cases under specialist care. Lower starting doses are used in elderly patients, kidney impairment and in patients of Asian origin, who can have higher blood levels of the drug.

• Take it once daily at a fixed time, with or without food; many patients keep a night-time routine like other statins, which is perfectly fine.
• If you forget a dose, skip it if the next is within 12 hours — never take two together.
• Do not stop Rosuvastatin on your own when reports normalise — the benefit continues only while you take it.

Rosuvastatin is generally well tolerated. Possible effects include:

• Muscle aches, tenderness or weakness — usually mild; report persistent, unexplained muscle pain promptly, especially with fever or dark urine, since very rare serious muscle breakdown (rhabdomyolysis) can occur.
• Headache, dizziness.
• Digestive upset — nausea, constipation or abdominal pain.
• Liver enzyme rise — usually without symptoms; periodic liver tests may be advised.
• Protein or blood traces in urine at high doses — usually transient; your doctor may check urine and kidney function.
• Small increase in blood sugar — slightly higher diabetes risk in predisposed people, outweighed by heart protection.

While taking Rosuvastatin:

• Report unexplained muscle pain, cramps or weakness early, particularly with fever or dark urine.
• Tell your doctor about kidney or liver disease, hypothyroidism, heavy alcohol use, or a family history of muscle disorders before starting.
• Mention that you take a statin whenever a new antibiotic, antifungal or heart medicine is being prescribed.
• Statins complement — never replace — healthy diet, exercise, weight control and stopping smoking.
• Asian patients may need lower doses; do not increase the dose yourself.
• Use reliable contraception if pregnancy is possible.
• Attend follow-up lipid, liver and sugar tests as scheduled.

Key interactions with Rosuvastatin:

• Ciclosporin — greatly raises rosuvastatin levels; combination generally avoided.
• Gemfibrozil and other fibrates — added muscle-toxicity risk; doses are limited.
• Some HIV/HCV protease inhibitor combinations — raise levels; dose restrictions apply.
• Warfarin — INR can rise; closer monitoring when starting or changing dose.
• Antacids containing aluminium/magnesium — reduce absorption; take them at least 2 hours after Rosuvastatin.
• Erythromycin — may lower rosuvastatin levels slightly.
• Unlike atorvastatin, grapefruit juice matters little here, but moderation is still sensible.

Rosuvastatin must not be used in:

• Active liver disease or persistent unexplained liver-enzyme elevation.
• Severe kidney impairment — high doses are contraindicated; lower doses only with caution under medical advice.
• Pregnancy and breastfeeding.
• Known allergy to rosuvastatin or any tablet ingredient.
• Concurrent ciclosporin therapy.
• Previous statin-induced severe myopathy or rhabdomyolysis — specialist decision only.
• The 40 mg dose is additionally avoided in patients with risk factors for muscle toxicity, including Asian ancestry, hypothyroidism and alcohol excess.

Pregnancy: Rosuvastatin is contraindicated in pregnancy. The developing baby needs cholesterol for normal growth, so statins are stopped before planned conception or as soon as pregnancy is confirmed. Women who can become pregnant should use effective contraception throughout treatment and tell the doctor immediately if a period is missed. Pausing the statin during pregnancy is generally safe for the mother.

Breastfeeding: Rosuvastatin may pass into breast milk and is contraindicated while breastfeeding. Discuss with your doctor when treatment can safely restart after the baby is weaned.

Keep Rosuvastatin below 30°C in a dry place, protected from light and moisture; do not store it in the bathroom. Keep tablets in the original pack until use and well out of the reach and sight of children. Never take it after the expiry date on the packaging, and return expired medicine to a pharmacy for safe disposal rather than discarding it with household waste.
