Overview
Pharmaniaga Simvastatin 20mg Tablet contains simvastatin 20mg, a statin (HMG-CoA reductase inhibitor) used together with diet and exercise to lower high cholesterol and triglyceride levels and to reduce the risk of heart attack, stroke, and other cardiovascular events in people with or at risk of heart disease.
Simvastatin works by blocking the liver enzyme that controls cholesterol production. This lowers LDL (“bad”) cholesterol and triglycerides, raises HDL (“good”) cholesterol slightly, and prompts the liver to remove more LDL cholesterol from the bloodstream.
How it Works
Simvastatin inhibits HMG-CoA reductase, the rate-limiting enzyme in the liver’s cholesterol production pathway. As the liver produces less cholesterol internally, it responds by increasing the number of LDL receptors on its surface, pulling more LDL cholesterol out of the blood and lowering overall cholesterol levels.
Directions for Use
Take Pharmaniaga Simvastatin 20mg Tablet once daily in the evening, with or without food, as simvastatin works with the body’s natural night-time cholesterol production cycle. Swallow the tablet whole with a glass of water and try to take it at the same time each evening.
Dosage
The usual dose of Pharmaniaga Simvastatin 20mg Tablet is 10-40mg once daily, started low and adjusted by your doctor based on your cholesterol response and cardiovascular risk. Higher doses are used less often because of an increased risk of muscle-related side effects. Your doctor will determine the right dose and monitoring schedule for you.

Frequently Asked Questions
What is Pharmaniaga Simvastatin 20mg Tablet used for?
Pharmaniaga Simvastatin 20mg Tablet is used to lower high cholesterol and triglycerides and to reduce the risk of heart attack and stroke in people with or at risk of cardiovascular disease.
Why should simvastatin be taken in the evening?
The liver produces more cholesterol at night, so taking simvastatin in the evening lines up with this natural cycle and gives a better cholesterol-lowering effect than other times of day.
Can I drink alcohol while taking this medicine?
It is best to limit alcohol, as both alcohol and simvastatin are processed by the liver, and combining them may increase the risk of liver-related side effects.
Is it safe to eat grapefruit while on simvastatin?
Large amounts of grapefruit or grapefruit juice should be avoided, as they can raise simvastatin levels in the blood and increase the risk of muscle-related side effects.
