High cholesterol is a serious health condition that can increase the risk of life-threatening problems such as heart attacks and strokes. This occurs because excess cholesterol leads to fatty plaque buildup inside arteries, narrowing them and restricting blood flow to vital organs. It can also cause peripheral artery disease (PAD), which results in painful symptoms in the limbs, and contributes to high blood pressure and kidney complications.
Statins are commonly prescribed medications that help lower cholesterol and reduce these risks. Among them, atorvastatin is one of the most widely used high-intensity statins, taken by millions of adults across the UK. While statins are generally safe and effective, the NHS has issued a warning outlining potential side effects of atorvastatin and guidance on when to seek medical help.
According to the NHS, “Like all medicines, atorvastatin can cause side effects in some people, but not everyone experiences them. Some side effects may improve after the first few days as your body adjusts to the medicine.” Most patients will see their cholesterol levels decline within four weeks of starting treatment.

Common side effects of atorvastatin, occurring in more than 1 in 100 users, include muscle aches, headaches, and digestive issues. The NHS advises patients to monitor these symptoms and seek advice if they persist or worsen.
Importantly, regular heavy alcohol consumption can increase the risk of side effects from atorvastatin, particularly liver problems. The NHS recommends limiting alcohol intake while on this medication.
If you experience side effects that make you consider stopping atorvastatin, consult your doctor before making any changes. Symptoms may be due to other causes, and your doctor may recommend adjusting your dose or switching medications rather than stopping completely.
Seek immediate medical attention by calling 999 or contacting a doctor or NHS 111 if you experience a serious allergic reaction to atorvastatin. Signs include swelling or blistering rash, itching, peeling skin, or difficulty breathing.
In summary, while atorvastatin remains an essential medication for managing cholesterol and preventing cardiovascular disease, patients should be aware of side effects and know when urgent care is necessary.
