The NHS notes that many people who take statins experience no or very few side effects, though others will experience “some troublesome, but usually minor, side effects, such as diarrhoea, a headache or feeling sick”.
It notes that a review of scientific studies into the effectiveness of statins found around one in every 50 people who take the medicine for five years will avoid a serious event, such as a heart attack or stroke, as a result.
The NHS recommends maintaining cholesterol levels below 5mmol/L.
In the UK, however, three out of five adults have a total cholesterol of 5mmol/L or above, and the average cholesterol level is about 5.7mmol/L, which can be a risk factor in heart disease.
