Side effects can vary between different statins, but common side effects include:
- Feeling sick
- Feeling unusually tired or physically weak
- Digestive system problems, such as constipation, diarrhoea, indigestion or farting
- Muscle pain
- Sleep problems
- Low blood platelet count.
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 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.
According to the NHS, your doctor will usually recommend lifestyle changes to reduce this risk before they suggest that you take statins.
