Atorvastatin

Atorvastatin belongs to a group of medicines called statins. It lowers the level of cholesterol in the blood, which helps reduce the risk of heart and circulation problems such as heart attacks and strokes [1].

It is prescribed for people with high cholesterol and for those at higher risk of cardiovascular problems, for example some people with diabetes or kidney disease [1]. It usually comes as tablets and is available only on prescription [1].

• Atorvastatin is usually taken once a day and is often needed long term, sometimes for life [1].
• It can be taken at any time of day, but try to take it at the same time each day [1].
• Most people take it without problems, and serious side effects are uncommon [1].
• Tell a doctor about any unexplained muscle pain, tenderness or weakness [1].

Atorvastatin can be taken by most adults and by children aged 10 and over, but it does not suit everyone [1]. It may not be suitable if you have had an allergic reaction to a statin, have liver disease, certain muscle conditions, or drink a lot of alcohol, and it is not recommended in pregnancy [1]. Your prescriber will check your health and, in some cases, arrange blood tests before and during treatment [1].

Take atorvastatin as your prescriber tells you and as set out on the label — usually one tablet a day, with or without food [1]. Try to take it at the same time each day so it becomes part of your routine [1]. If you miss a dose, the leaflet explains what to do; do not take two doses together to make up for a missed one [1]. Keep taking it unless your doctor advises otherwise, even though you may not feel any different [1].

Common side effects can include headaches, feeling sick, cold-like symptoms and mild digestive problems, and these are often mild [1]. Some people get muscle aches; rarely, statins can cause a more serious muscle problem, so tell a doctor promptly about unexplained muscle pain, tenderness or weakness, especially with a fever [1]. Get urgent help for signs of a serious reaction such as liver problems [1].

Atorvastatin can interact with a number of medicines, including some antibiotics and antifungals, certain heart and HIV medicines, ciclosporin and the blood thinner warfarin [1]. It is also best to limit grapefruit juice while taking it [1]. Tell your prescriber or pharmacist what else you take, including over-the-counter and herbal products, before starting it [1].

You can report a suspected side effect from atorvastatin to the MHRA through the Yellow Card scheme, which helps monitor medicine safety in the UK [2]. Seek medical help for any serious reaction as well as reporting it.
