Simvastatin Dosage

Your doctor will advise you on the appropriate dosage of Simvastatin. The normal starting dose is 20mg at night, although this will depend on your current cholesterol levels.

The tablets are to be swallowed whole with a sip of water. Take one per day, ideally in the evening. This is because the liver most actively produces cholesterol at night.

If you stop taking Simvastatin, your body will likely resume producing large quantities of cholesterol, which may lead to complications. So, it must be taken long-term.

Your doctor may adjust your dosage going forward, especially if you are at risk of coronary heart disease.

Simvastatin is most effective if combined with regular exercise and a healthy diet. Prescription medicines should only be one part of a healthy lifestyle.
