Statins are a group of medicines that can help lower the level of low-density lipoprotein (LDL) cholesterol in the blood.
LDL cholesterol is often referred to as "bad cholesterol", and statins reduce the production of it inside the liver.

Statins come as tablets that are taken once a day. The tablets should normally be taken at the same time each day – most people take them just before going to bed.
In most cases, treatment with statins continues for life, as stopping the medication causes your cholesterol to return to a high level within a few weeks.
If you ever forget to take your dose, don't take an extra one to make up for it. Just take your next dose as usual the following day.
If you accidentally take too many statin tablets (more than your usual daily dose), contact your doctor or pharmacist for advice, or call NHS 111.
Statins can sometimes interact with other medicines, increasing the risk of unpleasant side effects, such as muscle damage. Some types of statin can also interact with grapefruit juice.
It's very important to read the information leaflet that comes with your medication, to check if there are any interactions you should be aware of. If in doubt, contact your GP or pharmacist for advice.

Cases that involve more serious side effects, such as kidney failure, tend to get a great deal of media coverage, but these are rare. The British Heart Foundation states than just 1 in every 10,000 people who take statins will experience a potentially dangerous side effect.
The risks of any side effects also have to be balanced against the benefits of preventing serious problems. A review of scientific studies into the effectiveness of statins found that around one in every 50 people who take the medication for five years will avoid a serious event, such as a heart attack or stroke, as a result.
