Apologies, this is a very long post!
Statins are known by members of this forum to trigger/exacerbate RLS, although the NHS doesn’t formally recognise this.
Statins are the most prescribed drug in the world, recommended for the reduction of cholesterol. Many doctors will say that they are essential, that there are no alternatives, and benefits outweigh all side effects. But some of this is debatable.
Kaarina reminded us a few days ago that people shouldn’t just drop prescribed medications because they had an adverse effect on their RLS without discussing this with their doctor: this was particularly mentioned with reference to beta blockers and statins, but was of course good general advice.
I feel that it might be useful to have a post about statins, as when I had problems with these in 2021 (i) I was ignorant of the potential side effects (which weren’t discussed with me at the time of prescription), and (ii) I had some difficulty getting a consultant to listen to my side effects and to agree to take action – a fact that I’ve mentioned in Replies in the past. I just thought that I’d elaborate in case it might help anyone else.
There are some (minority) diverging views within medical and scientific communities as to whether statins are over-prescribed and on how serious the side effects are, which I will mention again at the end of this piece. But firstly some general points about statins, in case anyone doesn’t know, and the various brand names that are used:
“Statins are a group of medicines that can help lower the level of low-density lipoprotein (LDL) cholesterol in the blood….. Having a high level of LDL cholesterol is potentially dangerous, as it can lead to a hardening and narrowing of the arteries (atherosclerosis) and cardiovascular disease (CVD).” nhs.uk/conditions/statins/
They were developed from research into fungi: americanscientist.org/artic...
“Statins slow down LDL-cholesterol production by blocking an enzyme called HMG-CoA-Reductase.”
Common statins include atorvastatin (brand name: Lipitor and many others); rosuvastatin (Crestor, Ezallor Sprinkle); simvastatin (Zocor, Simvador); fluvastatin (Lescol, Canef, Vastin); lovastatin (Mevacor, Advicor, Altocor, Altoprev); pitavastatin (Livazo, Livalo, Zypitamag); pravastatin (Pravachol and others). In the UK mostly the generic names are used, while in the US 80% of prescriptions are in the brand names.
Statins are the most widely prescribed drugs in the world: guidelines for their prescription vary, but it has been reported that over 7 million Britons and around 40 million Americans have been prescribed statins. I recently read that c. 50% of American men over 60 were prescribed statins.
“You usually have to continue taking statins for life because if you stop taking them, your cholesterol will return to a high level.” NHS advice
“Many people who take statins experience no or very few side effects. Others experience some side effects, but these are usually minor, such as diarrhoea, a headache or feeling sick. Your doctor should discuss the risks and benefits of taking statins if they're offered to you. The risks of any side effects also have to be balanced against the benefits of preventing serious problems.” NHS advice
Statins are known by members of this forum to trigger/exacerbate RLS, although the NHS doesn’t formally recognise this.
According to the NHS, side effects can vary between different statins but common side effects include: headache, dizziness, feeling sick, feeling unusually tired or physically weak, digestive system problems, such as constipation, diarrhoea, indigestion or farting, muscle pain, sleep problems, low blood platelet count.
Uncommon side effects of statins include: being sick, memory problems, hair loss, pins and needles, inflammation of the liver (hepatitis), inflammation of the pancreas (pancreatitis), skin problems, such as acne or an itchy red rash, sexual problems such as loss of libido (reduced sex drive) or erectile dysfunction.
Rare side effects of statins include: muscle weakness (myopathy), loss of sensation or tingling in the nerve endings of the hands and feet (peripheral neuropathy), tendon problems.
I first heard about statins and some of the problems with them around 10 years ago from a work colleague. He had been put on statins, had a terrible experience with them, and then couldn’t get his medical team to prescribe anything else instead. It was statins or nothing. He eventually took himself off them (yes, admittedly a risky decision), changed his lifestyle and took more exercise, changed to a largely vegetarian and then a totally vegan diet, and in effect cured himself: 10 years later and he still has no health problems.
Nearly two years ago I had a Transient Ischaemic Attack (TIA, ‘mini-stroke’) and was referred to the UKs leading research centre into stroke and dementia, where atorvastatin was prescribed to lower LDL cholesterol (which wasn’t particularly high, but the statin prescription was described as ‘precautionary’). I was unhappy about the use of statins in the light of my ex-colleague’s experience, but was told that statins were the only possible treatment.
I then went through 6 months of bad nightly RLS symptoms – something that I’d previously largely got under control through using magnesium citrate – but even worse a long period of feeling unusually tired and physically weak, muscle pains, and digestive system problems including diarrhoea. I cannot stress enough how low these side effects made me feel.
It was only on this forum 18 months ago that I learned that the RLS resurgence at least was likely to be caused by the atorvastatin, and that I should get myself off them. I went back to the consultant who denied that there was any connection with RLS, which she clearly anyway only considered a mild inconvenience, and she wanted me to stay on statins. She didn’t explain that the feeling tired and weak etc could also be linked to the statin.
It was only when I threatened to take myself off the statin that she eventually agreed to put me on ezetimibe (brand names Ezetrol, Zetia) instead. I later found that ezetimibe, which works differently from statins in that it inhibits the intestinal absorption of cholesterol, is recommended in the UK if a statin is “inappropriate or not tolerated”. It generally works more slowly than a statin, so may not be suitable for those with very high LDL.
“Like all medicines, ezetimibe can cause side effects in some people, although not everyone gets them. Common side effects (affecting more than 1 in 100) include stomach (abdominal) pain, diarrhoea, farting more than usual, feeling more tired than usual
Serious side effects (affecting less than 1 in 10,000) include muscle pain, tenderness, weakness or cramps, yellow skin or the whites of your eyes turn yellow, pale poo and dark pee – this can be a sign of liver problems. severe stomach pain (just under your ribs) – this can be a symptom of pancreas problems.” NHS advice.
There have also been reports that ezetimibe triggers/exacerbates RLS, but it doesn’t for me. And it certainly doesn’t cause the tiredness and weakness that the statins did (my GP got me to try rosuvastatin for a while, but this had similar if less extensive side effects as the atorvastatin).
It’s possible that the reports linking ezetimibe to RLS may be partly due to the fact that ezetimibe may – particularly in the US - be supplied in combination with other drugs including statins: ezetimibe and simvastatin (Inegy, Vytorin); ezetimibe and atorvastatin (Liptruzet, Atozet); ezetimibe and rosuvastatin (Ridutrin); ezetimibe and bempedoic acid (Nustendi, Nexlizet). Or, of course, it may affect some because “we’re all different”.
Ezetimibe may be a better prescription than a statin for some people, and I have certainly found it so.
UPDATE 26/01/23
Other alternatives to statins include bempedoic acid which works by reducing the production of cholesterol in the liver. Common or very common side effects: anaemia; gout; hyperuricaemia; pain in extremity. Frequency not known: Diarrhoea; muscle spasms; nausea
And Nustendi (Nexlizet in the US) which combines ezetimibe with bempedoic acid. This may be a good alternative for people who cannot tolerate statins, but it too has a long list of possible side effects.

UPDATE 12/2/23
Another possibility with no adverse RLS reports is fenofibrate (Lipantil,Supralip; Triglide in the US)
Unfortunately, rather like ezetimibe, common or very common side effects of fenofibrate include abdominal pain, diarrhoea, flatulence, nausea, vomiting...

However, statins may remain necessary for some.
“The NHS, NICE, other guideline bodies in the UK, the British Heart Foundation and many organisations strongly support the use of statins to reduce the risk of cardiovascular events such as myocardial infarction (MI) and stroke. But the nature of how the drugs are used – as a preventive treatment prescribed at scale – can court controversy in the media.” BHF advice.
The controversy over prescription of statins in the UK hit the headlines in 2013 when the British Medical Journal (BMJ) claimed statins were being overprescribed to people with low risk of heart disease, and that the side effects were worse than previously thought. The debate has continued since then, with vigorous rebuttals in The Lancet and elsewhere, but also a measure of agreement in some medical and scientific circles. The majority feeling within the medical profession currently remains that the use of statins should be expanded rather than reduced, and that the benefits outweigh the side effects.
I would guess that this may partly be because not enough sufferers go back to their doctors to complain about their side effects. If you have no side effects that you can link to a statin, great. But if you do, please talk to your doctor – my consultant grudgingly agreed that I could come off, and my GP accepts (now that I’ve tried two statins) that in my case the side effects of statins do outweigh the benefits when an alternative is available.
In fact, cholesterol may in some circumstances be better reduced by modifying diet: some have had success by moving to a vegan diet. I don't (currently) have the willpower for this!
