Statins side effects: Colours in your urine and stools that could indicate liver damage

According to the NHS, serious side effects when taking atorvastatin – a type of statin – are rare and happen in less than one in 1,000 people.

The health body says to stop taking atorvastatin if you have pale poo, dark pee or yellow skin – this can be a sign of liver problems.

“Severe liver impairment is very rare,” Dr Larry Goldstein, professor and chairman of the department of neurology said.

He added: “Symptoms can include skin and eyes becoming yellow, dark urine, abdominal pain, itchy skin, pale stool and bruising.”
