🚨 Rare but Important Warning Signs
Seek medical advice promptly if you develop unexplained severe muscle pain, tenderness, or weakness, particularly with fever, marked tiredness, or dark/brown urine. Rarely, statins can cause serious muscle injury (rhabdomyolysis), which can damage the kidneys. FDA Access Data
Also contact a healthcare professional if you develop yellow skin or eyes, dark urine, loss of appetite, nausea/vomiting, or upper-abdominal pain, which can indicate liver injury. FDA Access Data
Should You Stop Atorvastatin?
Don’t stop it on your own. Statins are commonly prescribed long-term because stopping can allow cholesterol levels to rise again. If side effects are troublesome, your doctor can assess other causes and may adjust the dose or switch you to another statin or treatment. nhs.uk+1
Some medicines and grapefruit juice can increase atorvastatin exposure and the risk of side effects, so tell your doctor or pharmacist about all prescription medicines, over-the-counter medicines, vitamins, and herbal supplements you’re taking. nhs.uk
