Should I take a statin at all?
That depends on your overall cardiovascular risk rather than on your cholesterol number alone.
We calculate QRISK3 and show you the figure — including what it becomes with and without treatment. The decision is yours, made on real numbers rather than on a result that looked high on a printout.
Treatment is usually recommended at a 10-year risk of 10% or more, and after any heart attack, stroke or arterial disease regardless of the cholesterol level.
Do statins really cause muscle aches?
Here is the honest version. Muscle aches are the commonest complaint — but in blinded trials, rates are similar on statin and on placebo.
That does not mean your symptoms are imagined. It means that before abandoning statins altogether, it is worth stopping temporarily to see whether they resolve, then rechallenging — and most people who believed they could not tolerate statins do tolerate one, at a lower dose or as a different drug.
It is also worth checking thyroid and vitamin D, which cause muscle aches in their own right.
When are muscle symptoms serious?
Severe, widespread muscle pain with weakness or dark urine. Stop the statin and seek medical attention the same day.
That is rhabdomyolysis, it is rare, and it is quite different from an ache.
Do statins cause diabetes?
There is a small real increase in the risk of developing type 2 diabetes, mostly in people already close to the threshold.
It is outweighed by the cardiovascular benefit in anyone at genuine risk, and it is a reason to monitor HbA1c rather than to avoid treatment. You should hear about it rather than discover it later.
Can I lower it with diet instead?
Diet helps, and lifestyle change alone rarely achieves what a statin achieves — both are true.
Replacing saturated fat with unsaturated fat is the change with the best evidence, alongside soluble fibre and plant stanols. It is worth doing whether or not you take a tablet, because it improves overall risk.
Do I have to take it for life?
Generally yes — cholesterol rises again when it stops. The benefit accrues over years, which is why consistency matters more here than in most treatments.
Does it matter what time I take it?
For simvastatin, yes — in the evening. Atorvastatin and rosuvastatin are long-acting and can be taken at any time, which makes them easier to remember.
What about grapefruit?
Genuinely relevant with simvastatin and atorvastatin — it raises drug levels and increases the risk of muscle problems. Rosuvastatin and pravastatin are not affected.
Also tell any prescriber you take a statin, since certain antibiotics — clarithromycin especially — interact, and the statin is usually paused for the course.
My cholesterol is very high and my father had a heart attack at 50.
That combination should prompt assessment for familial hypercholesterolaemia — an inherited condition affecting roughly 1 in 250 people, substantially underdiagnosed, and a reason to treat from a much younger age.
It also means testing relatives, which is where much of the benefit lies. It needs specialist assessment, and referral is free on the NHS.
Is there an alternative if I truly cannot take statins?
Yes — ezetimibe, which is well tolerated and does not cause muscle symptoms, and bempedoic acid. For very high risk, PCSK9 inhibitors are available through NHS lipid clinics.
Nobody should be left untreated because a statin did not suit them.
Should I take red yeast rice instead?
No — it contains a statin, in an unregulated quantity. So you take the drug without knowing the dose, without monitoring, and with the same interactions and side effects.
That is the worst of both worlds, and a prescribed generic statin costs less.
