Condition: Rustelozebenensyndroom (RLS)

My Plan

Het syndroom van onrustige benen is een drang om de benen te bewegen, die erger wordt in de avond en bij rust, en die verlichting biedt zodra u opstaat en gaat lopen. De eerste stap is belangrijker dan welke pil dan ook: een bloedtest waar bijna niemand aan denkt, het serumferritinegehalte. Bij veel van deze aandoening is er tekort aan ijzer in de hersenen, en het herstellen hiervan verlicht de symptomen, zelfs wanneer de bloedtelling normaal is.

Regelmatige beweging helpt bij sommige mensen, een stabiele slaap helpt, en daarna volgt het controleren van medicijnen die symptomen kunnen uitlokken. De voorschrijfbare geneesmiddelen werken goed. De nieuwere alpha-2-delta-geneesmiddelen, zoals pregabalin, worden nu voorkeur gegeven boven de oudere dopamine-agonisten, omdat deze laatste de aandoening over jaren langzaam kunnen verergeren, een probleem dat augmentatie wordt genoemd.

What It Is

Restless legs syndrome, also called Willis-Ekbom disease, is a strong urge to move the legs, usually with an uncomfortable crawling, tugging, or fizzing feeling deep in them. Four features define it and separate it from ordinary leg discomfort. The urge comes on or worsens at rest. It eases while you are moving. It is worst in the evening and at night. And it is not better explained by another problem such as a cramp or an awkward sitting position. The relief from movement is the defining sign, and it is why people pace the bedroom or ride a stationary bike at midnight to ease the sensations.

In the REST general-population survey, 15,391 people completed questionnaires. 7.2% reported symptoms of any frequency. 2.7% had them at least twice a week and rated them moderately or severely distressing, the point where treatment is usually warranted. Only 6.2% of that group had ever been diagnosed. Their quality of life was as poor as that of people living with other serious chronic illnesses.

It grows more common with age, from about 3% of adults aged 18 to 29 up to 19% past 80 in one community survey. It is roughly twice as common in women. It often appears in the third trimester of pregnancy, where it usually settles within weeks of delivery.

Restless legs comes in two forms. Primary restless legs has no other cause behind it, often starts before age 40, and frequently runs in families. Secondary restless legs is driven by another cause that is often correctable, low iron most of all. Telling the two apart comes first, so a ferritin test and a review of the medicine list precede any prescription.

Most people with restless legs also have periodic limb movements of sleep, brief repetitive twitches or jerks of the legs through the night. The person rarely feels them; a bed partner often notices. These movements fragment sleep, one reason nights feel unrefreshing even when the hours in bed look adequate.

What Helps

Start with a blood test few people think to request, a serum ferritin, which measures your iron stores. The brain's iron shortage drives much of it, and correcting that eases symptoms.

A normal blood count does not rule iron out. The shortage that drives restless legs sits in the brain, where post-mortem work has found the movement-control area low in iron even when the blood looked fine.

When ferritin sits below about 75, iron by mouth over several months helps many people. Taking it every other day is absorbed better than a daily dose.

When tablets fall short, intravenous iron can do more. A single course of intravenous ferric carboxymaltose left 48% of people much or very much improved against 14% on a dummy infusion at four weeks. A quarter of those treated stayed off other restless legs medicines for at least 24 weeks.

Specialist guidelines put iron first. Iron by mouth suits the ferritin level above; intravenous iron is an option when ferritin is below 300. For the right person, intravenous iron can come first instead of after a tablet trial.

Regular exercise helps, best paired with restoring iron and steady sleep. A 12-week program of aerobic and lower-body strength work, three days a week, reduced symptoms against a control group. The randomized trial ran in 41 people (Aukerman, J Am Board Fam Med 2006). The trial was small, so pair exercise with the iron work. Being short of sleep sharpens symptoms, so regular, adequate sleep also makes them easier to bear.

Caffeine, alcohol, or nicotine in the evening triggers symptoms for many people. The link is individual, so test one at a time over about two weeks. One large survey found restless legs slightly more common among lighter drinkers. That is almost certainly a quirk of how people report their drinking. Alcohol offers no real protection, so if evening drinking worsens your symptoms, cutting it back is worth a try. Reviewing the medicine list comes next, since a drug started recently can be the trigger.

The prescription drugs come in two classes. The dopamine agonists (pramipexole, ropinirole, and rotigotine) cut symptom scores by about 5.7 points across 35 placebo-controlled trials in 7,365 people. They also roughly halved the periodic leg movements of sleep. Over months to years, though, a dopamine agonist can bring on augmentation, and that dropped the class to second choice.

The alpha-2-delta drugs, pregabalin and gabapentin enacarbil, have moved ahead of the dopamine agonists as the first prescription for many people. In a 52-week trial of 719 people, pregabalin eased restless legs about as well as pramipexole while causing augmentation far less often, 2.1% against 7.7% (Allen, NEJM 2014). It can also suit people whose legs come with pain or trouble sleeping.

Sleep

Dopamineagonisten verlaagden rusteloze-benen-scores met 5.7 punten over 35 studies bij 7,365 mensenStrong
In plain terms

Dopaminemiddelen verminderden rusteloze-benen-symptomen en de beenbewegingen tijdens de slaap duidelijk tegenover een neppil, ten koste van meer bijwerkingen. De studies waren te kort om augmentatie op te vangen, de geleidelijke verslechtering die na jaren kan verschijnen.

In detail

Bij het poolen van 35 placebogecontroleerde gerandomiseerde studies (N=7365) verlaagden dopamineagonisten de International RLS ernst-score met 5.7 punten tegenover placebo (95%-BI -6.7 tot -4.7) en verminderden zij periodieke ledemaatstijgingen met 22.4 per uur, hoewel patiënten meer ongewenste effecten hadden en vaker afhaakten (oddsratio 1.82). Augmentatie werd in deze korte studies niet betrouwbaar vastgelegd. Measured in: 7365 adults with restless legs across 35 placebo-controlled trials, most lasting up to seven months.. De studies liepen tot ongeveer zeven maanden, te kort om augmentatie aan te tonen, de belangrijkste reden waarom deze klasse nu na ijzer en de alfa-2-delta-middelen wordt gebruikt, niet eerst.

Over een jaar sloeg augmentatie toe bij 2.1% bij pregabaline tegenover 7.7% bij pramipexolStrong
In plain terms

Over een jaar verlichtte pregabaline rusteloze benen even goed als het dopaminemiddel pramipexol, terwijl het veel minder augmentatie veroorzaakte, de geleidelijke verslechtering die kan optreden met de dopaminemiddelen. Dit is een groot deel van waarom de alfa-2-delta-klasse nu vaak als eerste wordt gekozen.

In detail

In een gerandomiseerde, dubbelblinde studie van 52 weken bij 719 mensen verbeterde pregabaline 300 mg de ernstscore met 4.5 punten meer dan placebo over 12 weken (71.4% veel of zeer veel verbeterd tegenover 46.8%), en augmentatie over 40 tot 52 weken was lager met pregabaline dan met pramipexol 0.5 mg (2.1% tegenover 7.7%, p=0.001). Measured in: 719 adults with restless legs randomized to pregabalin, two doses of pramipexole, or placebo followed by active treatment.. Pregabaline kan slaperigheid, duizeligheid en gewichtstoename veroorzaken, en de studie registreerde een klein aantal meldingen van suïcidale gedachten, dus de keuze tussen klassen is individueel, niet automatisch.

IJzer verlichtte rusteloze benen met 3.78 punten op de 40-puntenschaal tegenover placebo over 7 studies bij 345 mensenModerate
In plain terms

Over gerandomiseerde studies heen verminderde ijzer de oncomfortabele drang-om-te-bewegen-symptomen vergeleken met een neppilletje, een bescheiden verbetering op de standaard ernst-schaal. Het hielp zelfs wanneer het ijzer in het bloed niet duidelijk laag was.

In detail

Een Cochrane-meta-analyse vond dat ijzer de International Restless Legs Scale-scores verbeterde tegenover placebo (gemiddeld verschil -3.78 op de schaal van 0 tot 40, 95%-BI -6.25 tot -1.31; 7 studies, 345 deelnemers; I2 66%), beoordeeld als matige zekerheid op GRADE, en het hielp of het bloedijzer nu duidelijk laag was of niet. Measured in: 428 adults with restless legs across 10 trials in the review, including some on dialysis, with the severity-scale result drawn from 7 trials and 345 people.. Een bescheiden gemiddeld effect met aanzienlijke variatie tussen studies, en de beste formulering, dosis en timing zijn nog niet vastgesteld; slaapkwaliteit en ledemaatstijgingen veranderden niet duidelijk.

Intraveneus ijzer liet 48% veel of zeer veel verbeterd achter tegenover 14% op placebo na vier wekenModerate
In plain terms

Een kuur ijzer toegediend via een infuus verbeterde rusteloze benen meer dan een nep-infuus, waarbij bijna de helft van de behandelden na vier weken veel beter was, en het effect bij sommigen maanden aanhield. Het is een optie wanneer tabletten niet voldoende zijn.

In detail

In een gerandomiseerde, placebogecontroleerde studie van 28 dagen bij 46 patiënten die andere behandeling hadden gestopt, verlaagde intraveneus ferri-carboxymaltose de ernst-schaal gemiddeld met 8.9 punten tegenover 4.0 bij placebo (p=0.040), en liet 48.3% veel of zeer veel verbeterd achter tegenover 14.3% (p=0.004), met voordeel dat tot minstens 24 weken aanhield voor een kwart van de behandelden. Measured in: 46 adults with restless legs syndrome discontinued from all other restless legs treatment for the trial.. Een kleine voorlopige studie bij 46 mensen; de auteurs roepen op tot grotere studies, en intraveneus ijzer kent zijn eigen kleine risico's en kosten, dus het volgt een ferritineresultaat, is geen eerste stap.

Guideline iron thresholds: oral iron at a ferritin of 75 or below, intravenous iron below 300Moderate
In plain terms

A specialist panel set the practical iron numbers the treatment rests on: try iron tablets when serum ferritin sits at 75 or below, and consider iron by drip, which can work as a first step, when it is below 300. The strongest trial evidence sits behind the intravenous iron.

In detail

An International Restless Legs Syndrome Study Group task force reviewed 31 qualifying iron-treatment studies drawn from 299 screened, of which four in adults were rated Class I (three of them for intravenous ferric carboxymaltose). It concluded that oral iron at 65 mg of elemental iron is possibly effective when serum ferritin is at or below 75 mcg/L, and that a 1000 mg course of intravenous ferric carboxymaltose is effective, and could be used first-line, when serum ferritin is below 300 mcg/L. Measured in: A task-force review of 31 iron-treatment studies in adults and children, selected from 299 screened, with the four Class I efficacy studies all in adults and all of intravenous iron.. The ferritin thresholds are consensus action points built on a small base of high-quality trials, four Class I studies, all of intravenous iron, so the oral-iron threshold rests on weaker evidence than the intravenous one.

Who this may not transfer to:Thresholds and dosing are set for adults; the task force found insufficient evidence to guide iron treatment in children.

Een drie-dagen-per-week, 12-wekenprogramma voor lichaamsbeweging verlaagde rusteloze-benen-symptomen in een studie bij 41 mensenPreliminary
In plain terms

Mensen die een driemaal-per-week oefenprogramma van 12 weken volgden, hadden minder ernstige rusteloze benen dan degenen die dat niet deden. Het is een kleine studie, maar het wijst op regelmatige beweging als een de moeite waard hefboom.

In detail

In een gerandomiseerde studie bij 41 mensen (23 voltooiingen), verbeterde een 12-wekenprogramma van aerobe training en weerstandstraining van de onderste ledematen drie dagen per week de symptomen significant tegenover een controlegroep, zowel op de International RLS ernst-schaal (p=0.001) als op een ordinale ernst-schaal (p<0.001). Measured in: 41 adults with restless legs randomized to exercise or control, average age about 54, 39% men, with 23 completing the trial.. Eén kleine studie met 23 voltooiingen en geen blindering, dus de omvang van het voordeel is onzeker; het werkt het best naast ijzeraanvulling en slaap, niet op zichzelf.

Rusteloze benen steeg van 3% op 18-29 jaar tot 19% boven de 80, en hing samen met roken en inactiviteitPreliminary · risk
In plain terms

In een groot gemeenschapsonderzoek was rusteloze benen vaker bij mensen die ouder, zwaarder, rokers waren of weinig bewogen, wat wijst op beweging en algemene gezondheid als hefbomen. Het vaak beschuldigde avonddrank was in deze momentopname, als dat iets, de andere kant op gekoppeld.

In detail

In een telefonisch onderzoek bij 1,803 volwassenen namen rusteloze-benen-symptomen toe met de leeftijd (3% op 18 tot 29 jaar, tot 19% boven 80) en waren ze geassocieerd met hogere body-mass index, roken, gebrek aan beweging, diabetes, een lager inkomen, en, onverwacht, een lagere alcoholconsumptie; een slechte geestelijke gezondheidsstatus droeg een gecorrigeerde oddsratio van 3.1. Measured in: 1,803 adults surveyed by telephone in the 1996 Kentucky Behavioral Risk Factor Surveillance Survey.. What could explain it instead: Age, body weight, smoking and inactivity travel together and each affects both restless legs risk and general health, so the associations may reflect a shared underlying profile, not any single factor acting alone.. Een enkelvoudig-vraag cross-sectioneel onderzoek, dus het toont associaties, geen oorzaken; het omgekeerde alcoholverband weerspiegelt hoogstwaarschijnlijk omgekeerde causaliteit of rapportage, geen beschermend effect.

Acupunctuur verbeterde rusteloze-benen-scores met 9.45 punten over 18 studies van lage kwaliteitPreliminary
In plain terms

Gepoolde, grotendeels kleine Chinese studies vonden dat acupunctuur rusteloze-benen-scores verbeterde, maar de studies waren van lage kwaliteit en vergeleken zelden met een neerpeilcontrole, dus de bevinding is veelbelovend, niet vastgesteld.

In detail

Een systematische review die 18 studies poolde (640 patiënten behandeld met acupunctuur alleen of gecombineerd met andere therapie, 447 controles) rapporteerde een gemiddelde verbetering van 9.45 punten op de International RLS Rating Scale (95%-BI -18.42 tot -0.49; p=0.04), waarbij werd opgemerkt dat de algehele kwaliteit van de opgenomen studies laag was en weinig een sham-acupuncturevergelijking gebruikten. Measured in: 1,087 people with restless legs across 18 trials, mostly conducted in China, comparing acupuncture (alone or added) with non-acupuncture treatment.. Lage studiekwaliteit, een zeer breed betrouwbaarheidsinterval dat bijna geen effect kruist, en weinig sham-gecontroleerde studies, dus de omvang van enig werkelijk effect is onzeker; de grotere sham-gecontroleerde studies die dit zouden beantwoorden, zijn niet gedaan.

How it works

IJzer en ferritine lagen laag in het bewegingscentrum van de hersenen bij zeven rusteloze-benen-hersenen tegenover vijf controlesModerate · mixed
In plain terms

Toen onderzoekers de hersenen van mensen met rusteloze benen onderzochten, had het bewegingscontrolegebied een tekort aan ijzer en aan het eiwit dat het opslaat, hoewel dit geen verspillende of degeneratieve ziekte was. De cellen leken niet in staat ijzer normaal op te nemen.

In detail

Bij een neuropathologisch onderzoek van zeven hersenen van mensen met het restless legs-syndroom tegenover vijf leeftijdgematchte controles, was de kleuring van ijzer en H-ferritine in de substantia nigra sterk verminderd, en was de kleuring van transferrinereceptoren op neuromelanine-cellen verminderd, wat wijst op een verstoorde ijzeropname door deze cellen, geen degeneratief verlies. Measured in: Seven post-mortem brains from people diagnosed with restless legs syndrome, compared with five age-matched brains from people with no neurological history.. Een zeer kleine weefselstudie van zeven hersenen tegenover vijf controles, dus het beschrijft een mechanisme, niet bewijs dat het voor iedereen geldt; het verklaart waarom de aandoening reageert op ijzer, zelfs wanneer het bloedbeeld normaal is.

Lager serumferritine hing samen met ergere rusteloze benen bij 27 patiënten, bijna alle ernstige gevallen op of onder 50Preliminary · risk
In plain terms

Bij mensen met rusteloze benen hadden lagere ijzervoorraden de neiging samen te gaan met ergere symptomen en slaap, en bijna iedereen met ernstige symptomen had een tamelijk laag ferritine. Het suggereert dat ferritine comfortabel boven het lage bereik wordt gehouden.

In detail

In een geblindeerd retrospectief onderzoek van 27 patiënten (18 vrouwen, 9 mannen, 29 tot 81 jaar) correleerde een lager serumferritine met een grotere ernst van rusteloze benen en slechtere slaapefficiëntie, en had alle behalve één patiënt met ernstige symptomen een ferritine op of onder 50 mcg/L. Measured in: 27 patients meeting restless legs criteria who had a ferritin measured near a sleep study and were not on iron or symptom-reducing medication.. What could explain it instead: People with lower ferritin may differ in age, blood loss, diet and coexisting illness, any of which can independently affect both iron stores and symptom severity, so part of the correlation may reflect those differences, not iron alone.. Een kleine correlationele review van 27 mensen, dus het koppelt een laag ferritine aan ergere symptomen, niet bewijs dat ijzeraanvulling ze oplost; de 50 mcg/L-grens is een signaal, en de huidige praktijk mikt hoger, boven ongeveer 75.

Measurement And Diagnosis

2.7% van de volwassenen heeft ernstig genoeg rusteloze benen om te behandelen, en slechts 6.2% was gediagnosticeerdModerate · mixed
In plain terms

Ongeveer één op de veertig volwassenen heeft ernstig genoeg rusteloze benen om behandeling te rechtvaardigen, toch hebben de meesten niet de diagnose gekregen, en hun kwaliteit van leven is even aangetast als bij andere langdurige aandoeningen. Het is veel voorkomend en wordt vaak gemist.

In detail

In de REST-bevolkingsstudie van 15,391 ingevulde vragenlijsten meldde 7.2% symptomen van rusteloze benen van enige frequentie, en 2.7% had klinisch significante symptomen (minstens twee keer per week en matig of ernstig hinderlijk). Van hen had slechts 6.2% een diagnose rusteloze benen gekregen, en hun SF-36-kwaliteit-van-levensscores kwamen overeen met andere chronische aandoeningen. Measured in: 16,202 adults interviewed with validated diagnostic questions across five Western countries, 15,391 completing the questionnaire.. What could explain it instead: Self-reported symptoms can overlap with leg cramps, neuropathy and positional discomfort, so questionnaire surveys may include some people whose symptoms are not truly restless legs, affecting the prevalence estimate.. Een op vragenlijsten gebaseerd onderzoek, dus het schat hoe veel de aandoening voorkomt en hoe belastend zij is, geen behandeling testend; het lage diagnosepercentage weerspiegelt het tijdperk en de omgeving.

How It Works

The iron shortage is in the brain more than the blood. In the brains of people who had restless legs, the substantia nigra, part of the movement-control system, was low in iron and in ferritin, the protein that stores it. The brain tissue itself was healthy; the low iron was not caused by cells dying off (Connor, Neurology 2003). The cells there seem unable to take up iron normally, so the brain's own supply can run low even while the blood is well stocked.

Iron is a cofactor the brain uses to make dopamine, the signaling chemical that helps smooth and coordinate movement. Short of iron, the dopamine system runs poorly. That fits both the symptoms and the relief that dopamine drugs bring. Dopamine signaling also follows a 24-hour rhythm, dipping in the evening and overnight, lining up with why symptoms are worst then. The same rhythm helps explain augmentation: sustained dopamine-agonist dosing over months appears to downregulate the receptors, worsening symptoms. Across large groups, the lower a person's iron stores, the worse the symptoms tend to be. So the practical goal is to keep ferritin well above the low end.

Go Deeper

Low iron and broken sleep are the two problems that most often travel with restless legs.

  • Iron-deficiency anemia: the low-iron picture that overlaps here, and how iron is restored when stores are down.
  • Insomnia: the lost sleep is the main harm, and the behavioral tools there help the broken nights.
  • Sleep regularity: a steady schedule matters, since too little rest makes the legs worse.
  • Walking and staying active: regular movement is a daily habit that eases symptoms.

The Chinese Medicine View

Chinese medicine has no single name for restless legs syndrome. Practitioners work from the affected leg, the timing of the symptoms, and the person's overall state. The nighttime urge to move, the crawling sensations, and the relief from walking are most often read as Blood or Yin failing to nourish and settle the sinews. Internal Wind then stirs, and the limbs cannot stay at rest.

This reading fits a problem that is worse at rest and better with movement. The overlap with the iron findings is an interesting parallel, since Blood in this tradition is loosely associated with what modern testing measures as iron and hemoglobin, but the tradition never measured ferritin, so the parallel is offered here as a lens, not as confirmation that Blood deficiency and iron deficiency are the same thing.

The tradition does not treat every case the same. A heavy, aching, damp presentation with a greasy tongue coat calls for draining Damp first. An older person who is depleted and cold needs warming and building, while the cooling, Wind-clearing approach suits a hot, agitated pattern instead. Herbal treatment is matched to the pattern, and it belongs with a qualified practitioner and a traceable supply.

The Chinese Medicine View

Getting the pattern right changes what a practitioner does: a depleted, nourishing picture and a heavy, damp one call for opposite approaches.

Blood and Yin deficiency with stirring Wind

The common nighttime picture: crawling, restless sensations and an urge to move that eases with walking, often with pale complexion, dry skin, poor sleep and a thin or pale tongue. The direction is to nourish Blood and Yin, calm the spirit, and settle the internal Wind. This is the pattern most often set next to the low-iron findings, though the resemblance is not evidence the two are the same mechanism.

Blood stasis in the channels

A fixed, deep, sometimes tingling discomfort, worse with long stillness, that can follow injury, surgery or years of the condition, with a dusky tongue. The direction is to move Blood and free the channels so the legs settle.

Damp obstructing the channels

A heavy, aching, sluggish version with swelling or a sense of fullness in the legs and a greasy tongue coat. Here nourishing alone would add to the load; the direction is to drain Damp and open the channels first.

Cautions

Extra restraint

Everything to be aware of is here, in one place. This practice suits most healthy people; a few situations call for real care.

Bij het beoordelen van 61 langetermijnstudies noemde een taskforce augmentatie als de voornaamste valkuil van dopaminemiddelen

Een taskforce van de International Restless Legs Syndrome Study Group die 61 studies van zes maanden of langer beoordeelde, stelde pregabaline als effectief vast voor maximaal een jaar (Level A) en de dopamineagonisten pramipexol, ropinirol en rotigotine als effectief voor maximaal zes maanden (Level A), en stelde consensusstrategieën op voor augmentatie, verlies van werkzaamheid en impulscontrolestoornissen die kunnen optreden bij langdurige dopaminerge behandeling. Augmentatie op lange termijn en impulsbeheersingsproblemen bepalen de keuze tussen geneesmiddelklassen meer dan kortetermijnverlichting, en het sterkste bewijs voor werkzaamheid op lange termijn geldt voor pregabaline en rotigotine.Garcia-Borreguero et al., the long-term treatment of restless legs syndrome/Willis-Ekbom disease: evidence-based guidelines and clinical consensus best practice guidance

Augmentation is the main long-term warning

The main long-term hazard in restless legs is augmentation, seen on a dopamine agonist such as pramipexole or ropinirole. Over months to years the symptoms can start earlier in the day, grow more intense, need a higher dose to hold, and spread to the arms or trunk. When symptoms break through, the natural move is to raise the dose. But a higher dose is the main driver of augmentation, so it worsens the very problem it appears to fix. If your restless legs is worsening on one of these drugs, do not increase the dose on your own. Raise it with the prescriber, since the fix is usually a planned change of drug or class. A task force reviewing the long-term studies also named two related problems (Garcia-Borreguero, Sleep Med 2013). The drug can gradually stop working. Some people develop compulsive behaviors such as gambling or shopping.

Restless legs can be secondary to something correctable

New or worsening restless legs is often driven by another cause worth finding. Low iron stores are the commonest and the most treatable, so ferritin comes first. It also appears in pregnancy, usually in the third trimester and usually settling after delivery, where iron and folate are worth checking and only some treatments are suitable. Kidney disease and dialysis both bring it on. They also change which treatments are safe. Several medicines can provoke it: some antidepressants, older sedating antihistamines, and dopamine-blocking anti-nausea drugs. Symptoms that began soon after a new medicine are a reason to review the list.

Check iron stores before supplementing

Iron helps when stores are low, but check ferritin before starting. The body has no easy way to shed a surplus, and too much iron carries its own harms. If ferritin stays low despite iron tablets, the iron may not be getting absorbed. The next step is intravenous iron, or a search for a source of blood loss.

The over-the-counter supplements have little trial evidence

Magnesium, vitamin C and E, and most over-the-counter remedies have only small, preliminary trials in restless legs. Iron and the prescription drugs carry the strongest evidence for moderate to severe symptoms. A stretch or a device can ease symptoms in the moment.

Most restless legs is a quality-of-life problem you can work on steadily, starting with a ferritin test you can order yourself. Take any decision about medication to the person who prescribes it, since that is where the choice between the drug classes and the handling of augmentation belong.

When to See Someone

Most restless legs is not dangerous, but a few signs point elsewhere and are worth getting seen about. See a doctor about any of these:

  • A single leg that is swollen, warm, red, or painful at rest. This differs from the two-sided, movement-relieved pattern of restless legs. It can mean a deep-vein clot needing same-day assessment(seek urgent care)
  • New numbness, weakness, burning, or pins-and-needles in the feet or legs. This suggests a nerve problem (neuropathy) that needs its own workup(seek urgent care)
  • Sudden, severe, or one-sided leg symptoms that do not fit the usual gradual, two-sided, evening pattern, which deserve a doctor to exclude other causes
  • Restless legs that keeps getting worse on a dopamine agonist, a sign of augmentation and a reason to plan a drug change with the prescriber
  • Symptoms that began soon after starting a new medicine, since several drugs can provoke restless legs and a swap may resolve it
  • Severe symptoms in pregnancy, where the safe treatment options are limited
  • Restless legs alongside kidney disease or dialysis, which changes the safe treatment options
  • A ferritin that stays low despite iron tablets, a sign the iron may not be getting absorbed (see Cautions)

Restless legs is common, it is not dangerous in itself, and most people improve once iron is addressed and a suitable treatment is found. You can order your own ferritin test and track it as you go.

Common Questions

Is iron worth checking when my blood test was normal?

Yes. The ferritin level worth acting on here is higher than the cutoff used to flag anemia, so a result labeled normal can still be too low. Pooling seven randomized trials in 345 people, iron improved symptoms by about 3.78 points on the 40-point severity scale against placebo (Trotti, Cochrane 2019). It helped whether or not blood iron was clearly low.

Which is better, dopamine agonists or drugs like pregabalin?

For a first prescription, pregabalin and the other alpha-2-delta drugs are now the usual first choice. The dopamine agonists still work and are well studied (Scholz, Cochrane 2011), so they remain an option, usually after iron and the alpha-2-delta drugs. The general order runs iron first, then the alpha-2-delta drugs, then the dopamine agonists.

Does acupuncture work for restless legs?

The evidence is preliminary. A review pooling 18 mostly small, low-quality trials reported better symptom scores, on average about 9.45 points on the severity scale (Huang, Ann Palliat Med 2021). The confidence interval nearly reached no effect, and few of the trials used a sham needle. The larger sham-controlled trials that would settle it have not been done. Strength of tradition is not the same as proof of effect, so acupuncture is reasonable to try alongside the iron and movement work.
