The First Steps With Statins
Statins: the few things that matter most, and the mistakes that catch people out early.
Medicines that lower LDL cholesterol by inhibiting its production in the liver.
Key takeaways
- Mechanism: inhibit HMG-CoA reductase in the liver
- Common starting dose, primary prevention: atorvastatin 20mg
- Most useful single change: Discuss a different statin or a lower dose before stopping altogether.
- Commonest mistake: Stopping because of aches without speaking to your GP.
- See a doctor if any of the signs under "When to speak to a doctor" below apply to you.
Why bother
They are among the most studied medicines in use and among the most stopped, usually over muscle aches that blinded trials attribute largely to expectation.
Start here
Begin here, with two things rather than ten.
- Discuss a different statin or a lower dose before stopping altogether
- Take it at the time of day you will actually remember
Then add these
Once the first two are automatic, these are worth adding.
- Keep taking it long term; the benefit accrues over years
- Report muscle symptoms rather than stopping silently

When to speak to a doctor
Contact a doctor urgently for severe, widespread muscle pain or weakness, especially with dark brown urine, which can indicate rhabdomyolysis. Also seek advice for yellowing of the skin or eyes, or unusual tiredness with loss of appetite. Stop before conceiving and during pregnancy.
Where this comes from
How this page was put together
Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.
