A pharmacist has urged people taking atorvastatin not to ignore unexplained changes in how they feel, after describing a patient who felt increasingly tired, weak and unlike themselves despite improved cholesterol numbers.
Raj Patel, known online as the 'Straight-Talking Pharmacist', shared the discussion on TikTok, where he has more than 100,000 followers. His video asks whether symptoms such as muscle pain, fatigue, and what he calls "brain fog" could leave some people feeling as though they are ageing.
Patient's experience with atorvastatin
He said: "Can atorvastatin for high cholesterol give you muscle pain, fatigue and brain fog that makes you feel like you're ageing? A patient of mine said to me my cholesterol numbers are a lot better but why do I feel a lot worse? And if you're on atorvastatin maybe a part of you understands that too."
"He was prescribed it to lower his cholesterol and reduce the risk of heart problems. On paper, it was doing exactly what it should and maybe your results look a lot better too."
The pharmacist explained how the patient had started questioning whether the symptoms were simply down to getting older. He added: "He told me he was exhausted all the time. His legs ached when he walked up the stairs. He felt weaker, flatter and not like the person he used to be."
Recognised side effects and evidence
The NHS does recognise muscle aches as a common side effect of atorvastatin, while feeling tired or weaker than usual is also listed among common statin side effects. Serious muscle damage is possible but rare, and can involve severe pain or weakness alongside other symptoms.
NICE's evidence is more nuanced, however. Its guidance says there is a real effect on muscle pain, but the increased risk is small, with many reported aches likely to have another explanation.
That is supported by a recent MHRA review of statin evidence. The regulator said statins caused a small relative increase in first reports of mild muscle pain or weakness, but more than 90 per cent of muscle-symptom reports among participants taking statins were not caused by the treatment.
What patients should do
Patel continued: "If a medicine is protecting your heart and quietly stealing your quality of life that matters. We didn't just look at his cholesterol. We looked at him because numbers can improve but you can feel worse and that really matters and should never be ignored."
His reference to "brain fog" also needs to be treated cautiously. NICE's evidence review found no apparent evidence that statins cause cognitive decline or dementia, while a systematic review published in 2020 found no evidence of adverse cognitive effects associated with statin use.
HEART UK says muscle aches and pains are among the most commonly reported side effects of statins, but notes that it can be difficult to establish whether symptoms are caused by the medicine or everyday life. It says doctors can consider options such as changing the statin or lowering the dose when appropriate.
Anyone concerned about symptoms should therefore speak to a GP or pharmacist before making changes to treatment. NHS advice says people should continue taking atorvastatin unless a healthcare professional advises them to stop, meaning unexplained symptoms should be discussed rather than simply ignored.
