The most effective relief for restless legs starts with checking your iron levels, cutting out substances that worsen symptoms, and adding regular physical activity. Beyond those basics, several medications and non-drug strategies can significantly reduce the uncomfortable urge to move your legs, especially at night. What works best depends on what’s driving your symptoms.
Check Your Iron Levels First
Low iron is one of the most common and fixable causes of restless legs. Even if your iron levels are technically “normal” by standard lab ranges, they may still be too low to keep restless legs at bay. The threshold that matters here is a ferritin level (a measure of stored iron) of 75 ng/mL or below. If yours falls at or under that number, oral iron supplements can help. The International Restless Legs Syndrome Study Group recommends oral iron therapy for anyone with RLS whose ferritin is below 75, and intravenous iron for moderate to severe cases with ferritin below 300.
This is worth checking before trying anything else. A simple blood test measuring ferritin and transferrin saturation gives you the answer. If your levels are low, iron supplementation alone may be enough to reduce or eliminate your symptoms entirely. If you do supplement, taking iron with vitamin C on an empty stomach improves absorption.
Substances That Make It Worse
The American Academy of Sleep Medicine identifies several common triggers that can worsen restless legs or even cause flare-ups on their own. Alcohol, caffeine, antihistamines (the kind found in many over-the-counter sleep aids and allergy medications), and certain antidepressants that affect serotonin all make the list. If you’re taking any of these regularly, reducing or eliminating them is considered the first step in managing RLS, before any other treatment.
Interestingly, the research on caffeine and alcohol isn’t as straightforward as you might expect. A large prospective study tracking men and women over time found no statistically significant link between caffeine consumption and RLS risk, even at high intake levels. Alcohol actually showed a trend toward being protective rather than harmful. Still, many people with RLS report that caffeine and alcohol trigger individual episodes, so it’s worth paying attention to your own patterns even if the population-level data is mixed. Antihistamines, on the other hand, are consistently linked to worsening symptoms and are worth avoiding if you can.
Exercise and Stretching
Regular physical activity is one of the best-supported non-drug treatments. An eight-week study comparing aerobic exercise and stretching programs (three sessions per week) found that aerobic exercise reduced RLS symptom scores by 21%, while stretching reduced them by 18%. Both improvements were statistically significant. The aerobic exercise group did moderate-intensity workouts, not anything extreme.
The key is consistency. A single workout won’t do much, but sticking with a routine over several weeks produces meaningful relief. Yoga and massage have also shown benefits in reviews of non-drug treatments. One thing to note: very intense exercise late in the evening can sometimes trigger symptoms in some people, so earlier sessions tend to work better.
Compression Devices
Pneumatic compression devices, the type that wrap around your legs and inflate sequentially to improve blood flow, have shown surprisingly strong results. In a randomized, sham-controlled trial, people using real compression devices saw their restless legs severity scores drop from 14.1 to 8.4 (on a scale where lower is better). A full third of participants experienced complete relief, compared to zero in the group using fake devices. Daytime function improved by 21%, sleep quality by 16%, and fatigue levels dropped significantly.
These devices are available for home use and don’t require a prescription in most cases. They’re a solid option if you want drug-free relief or something to use alongside other treatments.
Weighted Blankets
Weighted blankets haven’t been studied as extensively for restless legs as other treatments, but early evidence is encouraging. They appear to reduce the frequency of leg movements during sleep and improve overall sleep quality. In clinical reports, patients using weighted blankets combined with sleeping in a cooler room showed significant improvement without needing medication changes. If you’re looking for a low-risk, low-cost option to try tonight, a weighted blanket in the range of 10 to 15 percent of your body weight is a reasonable starting point.
Magnesium Supplements
A pilot study testing 200 mg of magnesium citrate daily for eight weeks found significant improvement in both symptom severity and quality of life in people with restless legs. Notably, the improvements occurred even though participants’ blood magnesium levels didn’t change, which suggests the benefit may come through a different mechanism than simply correcting a deficiency. This was a small, open-label study (12 participants, no placebo group), so the results are preliminary. But magnesium citrate is inexpensive and generally well tolerated, making it a reasonable option to try.
Prescription Medications
When lifestyle changes and supplements aren’t enough, the American Academy of Sleep Medicine’s strongest recommendations go to a class of medications that calm overactive nerve signals. These are the current first-line prescription options, all backed by strong recommendations and moderate-quality evidence. In clinical trials, about 73 to 78% of people taking these medications were rated as treatment responders after 12 weeks, compared to roughly 39% on placebo.
You may have heard that dopamine-boosting medications were once the go-to treatment for restless legs. That’s changed. The major problem with those drugs is something called augmentation, where the medication actually makes your symptoms worse over time, causes them to start earlier in the day, or spreads the sensations to your arms. Augmentation rates vary widely depending on the specific medication, ranging from about 1.5% to as high as 73% with older formulations. Because of this risk, nerve-calming medications have largely replaced dopamine-based drugs as the preferred first choice.
Restless Legs During Pregnancy
RLS is common during pregnancy, and treatment options are more limited. Non-drug approaches are the priority: moderate-intensity exercise, yoga, massage, and compression devices all have evidence supporting their use. Avoiding known triggers matters here too.
If your ferritin is below 75, oral iron supplementation is considered safe and is often the first pharmacological step. The preferred form is ferrous sulfate taken once or twice daily. For severe cases where oral iron isn’t working and ferritin remains very low, intravenous iron can be given after the first trimester. Other medications are generally reserved for severe, treatment-resistant cases and are used cautiously, ideally after the first trimester. The good news is that pregnancy-related RLS usually improves or resolves after delivery.
