Simvastatin
About Simvastatin
Simvastatin is a prescription medicine used to lower high cholesterol and triglyceride levels in the blood. It belongs to a group of medicines called statins, which reduce the amount of cholesterol made by the liver. This helps lower 'bad' cholesterol (LDL) and triglycerides while increasing 'good' cholesterol (HDL), reducing the risk of heart attack, stroke, and other cardiovascular complications.
Take Simvastatin exactly as prescribed by your doctor, usually once daily in the evening, with or without food. Although cholesterol levels may begin to improve within 2–4 weeks, the full effect is usually seen after about 4 weeks of regular treatment. Continue taking the medicine even if you feel well, as high cholesterol often has no symptoms. Following a heart-healthy lifestyle, including regular exercise, quitting smoking, maintaining a healthy weight, and limiting foods high in saturated and trans fats, can further improve cholesterol levels.
Most people taking Simvastatin do not experience serious side effects. Common side effects include headache, stomach discomfort, constipation, nausea, or muscle pain. These are usually mild and temporary. However, seek immediate medical attention if you develop unexplained muscle pain, tenderness, or weakness, especially if accompanied by fever or dark-coloured urine, or if you notice yellowing of the skin or eyes, severe tiredness, or persistent abdominal pain.
Before taking Simvastatin, tell your doctor if you have liver disease, kidney disease, thyroid disorders, diabetes, or a history of muscle problems. Older adults may be more likely to experience muscle-related side effects and may require closer monitoring. Do not take this medicine if you have active liver disease, are pregnant, planning to become pregnant, or are breastfeeding. Avoid grapefruit and grapefruit juice while taking Simvastatin, as they can increase the amount of the medicine in your body and raise the risk of side effects. Limit alcohol intake because excessive alcohol consumption may increase the risk of liver problems. If you have any questions about using this medicine safely, your doctor or Apollo pharmacist can guide you.

Patients Concern
Disease/Condition Glossary
Hyperlipidaemia: Hyperlipidaemia is commonly known as high cholesterol. Cholesterol is a fatty substance that is naturally produced in the liver because every cell uses it. Cholesterol is also found in fatty foods such as cheese, red meat, and eggs. High cholesterol levels might cause a build-up of fat on the arteries' walls, leading to blockage of blood flow to the heart and other body parts that could cause heart disease, heart attack or stroke. Cholesterol is mainly of two types, namely 'bad cholesterol' and 'good cholesterol'. Bad cholesterol comprises low-density lipoprotein (LDL) and triglycerides (TG) which deposit fat in the arteries leading to their blockage. Good cholesterol consists of high-density lipoprotein (HDL), which prevents the deposition of fats. Risk factors of high cholesterol are a high-fat diet, obesity, lack of physical exercise, and smoking. Usually, there are no specific symptoms of raised or high cholesterol levels, so it is advisable to have complete cholesterol tests (lipid profile tests) at least once a year. It will help monitor your heart health and risk of heart attack or stroke.
