NHS warns of 'serious' Atorvastatin side effects and drug interactions — patients told to 'call 111' for muscle damage symptoms such as pain

The NHS has issued a warning regarding atorvastatin, a commonly prescribed cholesterol-lowering medication, highlighting the potential for serious side effects and drug interactions. Patients are advised to seek immediate medical attention if they experience symptoms such as unexplained muscle pain, which may indicate muscle damage or kidney issues.

The NHS stated, "Some medicines can affect the way atorvastatin works and can increase the chances of you having serious side effects, such as muscle damage." Medications that can interact negatively with atorvastatin include antibiotics like erythromycin and clarithromycin, blood thinners like warfarin, and heart medications such as amiodarone.²

Common side effects reported by more than one in 100 patients include nausea, headaches, and cold-like symptoms. However, the NHS emphasizes that patients should stop taking atorvastatin and contact a doctor if they experience severe symptoms, including yellowing of the skin or eyes, which may indicate liver problems, or severe stomach pain, a sign of pancreatitis.

Additionally, the NHS warns that excessive alcohol consumption can heighten the risk of side effects. Patients are encouraged to limit grapefruit juice intake as it may also increase the likelihood of adverse effects. The NHS advises, "You can eat as normal while taking atorvastatin, but avoid having too much grapefruit juice as it can increase the chance of side effects."
