What is Simvastatin for?

Simvastatin is a cholesterol lowering drug that works primarily by blocking the enzyme involved in cholesterol synthesis, especially in the liver, and hence reduces  cholesterol levels. It is the first-line medication used for hypercholesterolaemia or hyperlipidemia. 

 

The detailed indications of Simvastatin include primary hypercholesterolemia or combined (mixed) hyperlipidemia in patients who did not respond adequately to diet and other appropriate measures, homozygous familial hypercholesterolemia in patients who have not responded adequately to diet and other appropriate measures, and prevention of cardiovascular events in patients with cardiovascular disease or at high risk of having a cardiovascular event (e.g. people who smoke, people with diabetes).

How to use it?

Simvastatin is taken by mouth as tablets. Most people take it on a daily basis in the evening. The dose range of Simvastatin is 5 to 80 mg once daily. However, higher doses of 80 mg daily are generally no longer prescribed because of a higher risk of severe muscle breakdown (rhabdomyolysis). 

 

Lower doses are often prescribed in Asians and your doctor will typically start with an initial dose of 5 to 20 mg daily. The dose of Simvastatin can be adjusted based on your cholesterol levels.

What are the side effects of Simvastatin?

The most common side effects of Simvastatin are muscle pain, muscle weakness, and shoulder pain. Rare side effects include an increased risk of diabetes, cognitive impairment (inability to focus or remember) and severe muscle breakdown (rhabdomyolysis).

Who should not take Simvastatin?
