Restless Legs Syndrome
2 medicines
Restless legs syndrome causes an uncomfortable urge to move the legs, usually worse in the evening or at night, and it responds well to dopamine-acting medicines such as pramipexole and ropinirole.
Key facts
- Restless legs syndrome (RLS) is a neurological condition that produces an irresistible urge to move the legs, usually with crawling, tingling or aching sensations.
- Symptoms usually appear in the evening or at night and ease briefly with walking or stretching, making RLS a common cause of poor sleep.
- It is linked to low dopamine activity in the brain and spinal cord; iron deficiency often compounds it, since iron is needed to produce dopamine.
- Moderate to severe RLS is treated with dopamine agonists, pramipexole or ropinirole, alongside simple sleep and lifestyle measures.
What drives the symptoms
The underlying mechanism involves dopamine signalling in the brain and spinal cord. When dopamine activity falls in the pathways that regulate movement, the legs generate the restless, crawling sensations typical of RLS. Iron deficiency can compound the problem, because iron is needed to produce dopamine, so checking ferritin levels at first presentation is worthwhile. Secondary RLS also shows up with pregnancy, kidney disease, and certain medicines.
Managing restless legs syndrome
For moderate to severe RLS, dopamine agonists are the most established treatment. Pramipexole and ropinirole both target dopamine receptors and can meaningfully reduce how often and how intensely symptoms occur. Doses start low to limit the risk of augmentation, a gradual worsening of symptoms that can happen with longer-term use and should be raised with a doctor if noticed.
Everyday measures that help
Keeping a consistent sleep schedule, limiting caffeine and alcohol in the evening, and gentle leg stretches or a warm bath before bed can all ease symptom severity on a given night. These measures work alongside medicine rather than replacing it once symptoms are moderate to severe.
When to see a doctor
See a doctor if leg symptoms are disrupting your sleep regularly, if symptoms are worsening despite treatment, or if you have signs of iron deficiency such as persistent tiredness. A blood test for ferritin is a simple first step.
