Crestor 20mg Tablet 28s

Crestor 20mg Tablet belongs to a class of medicines known as statins — more precisely, HMG-CoA reductase inhibitors — and contains Rosuvastatin Calcium as its active ingredient, a potent and widely prescribed synthetic statin that has been extensively studied in large-scale clinical trials over many years. As with all statin medicines, Crestor can cause side effects, and the ones most worth being aware of include muscle pain or weakness (myalgia), headache, abdominal discomfort, and in rare but serious cases, a condition called rhabdomyolysis, which involves severe muscle breakdown that requires immediate medical attention. If you are considering this tablet, there are a few important things you should know: Crestor 20mg is a prescription-only medicine in Malaysia, meaning you will need a valid doctor's prescription to purchase it, and it is typically taken as a long-term daily medicine rather than a short course. It is also important to tell your doctor about all other medicines you are taking — particularly certain antibiotics, antifungals, or blood thinners — and to avoid drinking large amounts of grapefruit juice during treatment, as these factors can affect how the medicine works in your body.

How to Take Crestor 20mg Tablet

Crestor 20mg Tablet is taken orally — swallow the tablet whole with a glass of water and do not crush, chew, or split it, as this may affect the release and absorption of the active ingredient. It can be taken at any time of day, with or without food, but it is best to take it at the same time each day to maintain a consistent level of the medicine in your bloodstream. If you miss a dose, take it as soon as you remember — unless it is almost time for your next scheduled dose, in which case skip the missed dose and continue with your regular schedule; never double up to compensate for a missed dose.

Dosage of Crestor 20mg Tablet

The usual starting dose of Crestor for most adults is 5mg to 10mg once daily, with the dose adjusted by a doctor based on individual patient response, lipid targets, and tolerability — the 20mg dose is a mid-range therapeutic dose prescribed when lower doses are insufficient to meet treatment goals. The maximum approved dose is 40mg once daily, and dosage adjustments must always be made under the supervision of a qualified healthcare professional; do not increase or reduce your dose without consulting your doctor first.

Shelf Life of Crestor 20mg Tablet

Shelf Life: 36 months (3 years) from the date of manufacture when stored correctly under recommended conditions

Always check the expiry date printed on both the outer carton and the individual blister strip before taking each tablet. An expired tablet must not be used — the potency and chemical stability of Rosuvastatin Calcium may be compromised beyond the stated shelf life, which could affect both the efficacy and safety of the medicine. Return any expired tablets to a licensed pharmacy for safe, environmentally responsible disposal; do not discard them in household bins or flush them down the toilet or sink.

How to Store Crestor 20mg Tablet

• Store at room temperature, below 30°C, in a cool and dry environment
• Keep away from direct sunlight, humidity, and heat sources — avoid storing in bathrooms, near kitchen sinks, or on windowsills
• Do not refrigerate or freeze unless explicitly directed on the product packaging
• Keep the tablets in their original blister packaging until the time of use to protect them from light and moisture
• Store in the original outer carton to preserve all product labelling, batch number, and expiry date information
• Keep out of reach and sight of children at all times — ideally in a locked medicine cabinet
• Do not transfer tablets into an unmarked or secondary container, as this increases the risk of accidental misidentification or misuse
• If you are travelling, keep the tablets in your carry-on luggage rather than checked baggage to avoid exposure to extreme temperature variations in cargo holds

Active Ingredient of Crestor 20mg Tablet

Active Ingredient: Rosuvastatin Calcium 20mg (equivalent to Rosuvastatin 19.6mg)

Rosuvastatin is a fully synthetic, second-generation statin and one of the most potent HMG-CoA reductase inhibitors currently available in clinical practice. Unlike some earlier statins, Rosuvastatin is primarily hydrophilic (water-soluble), which means it has a lower tendency to penetrate muscle and brain tissue — a pharmacological property that is associated with a relatively favourable tolerability profile compared to lipophilic statins. It is included in major international clinical guidelines for lipid management and is recognised by the World Health Organization (WHO) as a medicine of global therapeutic importance. Each Crestor 20mg tablet contains Rosuvastatin Calcium as the sole active pharmaceutical ingredient, alongside inactive excipients that may include microcrystalline cellulose, lactose monohydrate, tribasic calcium phosphate, crospovidone, magnesium stearate, hypromellose, triacetin, and titanium dioxide — refer to the full product package insert for the complete excipient list.

Side Effects of Crestor 20mg Tablet

Side effects may occur with Crestor 20mg Tablet. The following have been reported across clinical studies and post-marketing surveillance for Rosuvastatin:

Common Side Effects:

• Headache
• Myalgia (muscle pain or aching without elevated creatine kinase)
• Abdominal pain or discomfort
• Nausea
• Constipation
• Asthenia (generalised weakness or fatigue)
• Dizziness
• Elevated liver enzyme levels (detected on blood tests — usually asymptomatic)

Less Common Side Effects:

• Myopathy (muscle weakness with elevated creatine kinase levels)
• Arthralgia (joint pain)
• Peripheral oedema (swelling of the legs or ankles)
• Insomnia or sleep disturbance
• Depression or mood changes (reported in post-marketing data)
• Proteinuria (protein in the urine — typically transient and dose-dependent)
• Haematuria (blood in the urine — rare)
• Pancreatitis (inflammation of the pancreas — rare)
• Thrombocytopenia (reduced platelet count — rare)

Rare but Serious — Seek Immediate Medical Attention:

• Rhabdomyolysis: severe muscle breakdown characterised by intense muscle pain, dark or cola-coloured urine, and significant elevation in creatine kinase — a medical emergency requiring urgent hospital assessment
• Immune-mediated necrotising myopathy (IMNM): a rare autoimmune muscle condition associated with statin use
• Severe hepatotoxicity: significant liver damage, typically indicated by jaundice, dark urine, or severe upper abdominal pain
• Serious allergic reactions including angioedema (swelling of the face, lips, tongue, or throat) or anaphylaxis
• Interstitial lung disease (rare — presents as persistent cough, breathlessness, or unexplained weight loss)

Contact your doctor immediately if you experience any unexplained muscle pain, tenderness, or weakness during treatment — particularly if accompanied by fever, unusual tiredness, or dark urine. This is not a complete list; refer to the full prescribing information or package insert for all reported adverse events.

Contraindications of Crestor 20mg Tablet

• Known hypersensitivity or allergic reaction to Rosuvastatin, Rosuvastatin Calcium, or any inactive excipient in the formulation
• Active liver disease or any condition causing persistent, unexplained elevations in serum transaminases (liver enzymes) exceeding three times the upper limit of normal
• Severe renal impairment (creatinine clearance below 30 mL/min) — a reduced 5mg dose ceiling applies in moderate renal impairment; use of 20mg or 40mg is contraindicated in this population
• Myopathy (any current muscle disorder that is not clearly explained by another cause)
• Concomitant use of ciclosporin (cyclosporine) — combination significantly increases Rosuvastatin plasma concentrations and myopathy risk
• Pregnancy — Rosuvastatin is contraindicated throughout all trimesters due to the potential for foetal harm related to inhibition of cholesterol biosynthesis
• Breastfeeding — Rosuvastatin is excreted into breast milk and must not be used by nursing mothers
• Women of childbearing potential who are not using reliable contraceptive measures — effective contraception must be confirmed prior to and throughout treatment
• Hereditary conditions involving lactose or galactose intolerance (due to lactose content in the tablet formulation)

Use with caution and under close medical supervision in patients with hypothyroidism, a personal or family history of hereditary muscular disorders, a history of prior statin-induced myopathy, significant alcohol consumption, or Asian ancestry — pharmacokinetic studies indicate higher Rosuvastatin plasma concentrations in certain Asian populations, which may necessitate lower starting doses.

Drug & Food Interaction of Crestor 20mg Tablet

Drug Interactions:

• Ciclosporin (Cyclosporine): Contraindicated — dramatically increases Rosuvastatin plasma concentrations (up to 7-fold), greatly elevating the risk of myopathy and rhabdomyolysis
• Gemfibrozil and other fibrate medicines (e.g., fenofibrate): Significantly increases the risk of myopathy and rhabdomyolysis when combined with statins; the combination should be avoided or used only under very close specialist supervision
• Anticoagulants — Warfarin and other coumarin-based blood thinners: Rosuvastatin potentiates the anticoagulant effect, potentially elevating INR and increasing bleeding risk; INR monitoring is essential on initiation and after dose changes
• Antacids containing aluminium or magnesium hydroxide: Reduce Rosuvastatin absorption by approximately 50% when taken simultaneously — separate administration by at least 2 hours
• Protease inhibitors used in HIV treatment (e.g., lopinavir/ritonavir, atazanavir/ritonavir): Significantly increase Rosuvastatin exposure; dose reduction and close monitoring are required
• Fusidic acid (topical or systemic antibiotic): Rare cases of myopathy reported; consider temporary suspension of statin therapy if systemic fusidic acid is required
• Colchicine: Combination may increase the risk of myopathy — use with caution
• Niacin (nicotinic acid) at lipid-modifying doses: Combined use may increase myopathy risk
• Oral contraceptives and hormone replacement therapy (HRT): Rosuvastatin may increase plasma concentrations of ethinylestradiol and norgestrel — dose adjustments to hormonal contraceptives may be needed

Food & Beverage Interactions:

• Grapefruit and grapefruit juice: Unlike some other statins metabolised via CYP3A4, Rosuvastatin is not a CYP3A4 substrate, so the interaction with grapefruit juice is minimal compared to atorvastatin or simvastatin — however, caution remains advisable and large quantities should still be avoided
• Alcohol: Excessive and regular alcohol consumption significantly increases the risk of liver toxicity (hepatotoxicity) during statin therapy — heavy drinking should be avoided throughout treatment
• High-fat meals: While food does not significantly affect the overall bioavailability of Rosuvastatin, maintaining a heart-healthy, low-saturated-fat diet is considered an integral part of responsible statin therapy management

Quick Tips for Crestor 20mg Tablet

• Take Crestor at the same time every day to maintain consistent blood levels — pick a time that is easy to remember, such as with breakfast or at bedtime
• Do not crush, chew, or break the tablet — swallow it whole with a full glass of water
• Never stop taking Crestor without consulting your doctor first, even if you feel well — statin therapy is typically a long-term commitment
• Report any unexplained muscle pain, weakness, or tenderness to your doctor promptly — especially if it is accompanied by dark urine or fever, as this may signal a serious muscle condition
• Avoid excessive alcohol consumption throughout your course of treatment to protect your liver
• Store tablets below 30°C, in a cool and dry place, away from sunlight, and in the original blister packaging
• Keep all scheduled blood tests and follow-up appointments — your doctor will monitor your liver function and lipid profile periodically
• Inform all healthcare providers (including dentists and other specialists) that you are taking Crestor before any new medicine is prescribed
• Do not take antacids containing aluminium or magnesium within 2 hours of your Crestor dose, as they reduce absorption
• Check the expiry date on the blister strip and outer carton before each dose — do not use expired tablets
• If you are planning a pregnancy, discuss stopping Crestor with your doctor well in advance — it is contraindicated in pregnancy and breastfeeding
• Return any unused or expired tablets to a licensed pharmacy for proper disposal — do not dispose of them in household waste
