Restless Legs Treatment Has Changed: Why Guidelines Now Favor Gabapentin and Iron Over Ropinirole
Sleep & NighttimeArticleFor years, ropinirole and pramipexole were the go-to pills for restless legs. The American Academy of Sleep Medicine's newest guideline now suggests against their standard use because of a worsening effect called augmentation. It strongly recommends gabapentin-type medicines, checking iron, and IV iron when levels are low.

Restless legs syndrome (RLS) brings an urge to move your legs, usually in the evening or at night, that eases with movement. Our guide to why legs feel restless at night covers the basics. The American Academy of Sleep Medicine (AASM) updated its treatment guideline, and it reshuffles what doctors reach for first.
Step 1: check iron and triggers
- Iron tests for everyone with significant RLS, including ferritin and transferrin saturation, ideally in the morning after skipping iron supplements and iron-rich foods for 24 hours.1
- Iron is suggested if ferritin is 75 or lower or transferrin saturation is under 20%, and IV iron only if ferritin is 75 to 100. These targets are higher than for the general population.1
- Look for triggers: alcohol, caffeine, sedating antihistamines, some antidepressants, some anti-nausea or antipsychotic drugs, and untreated sleep apnea.1
Our article on RLS with normal hemoglobin explains why iron can matter even without anemia.
Strongly recommended
- Gabapentin, gabapentin enacarbil and pregabalin1
- IV iron (ferric carboxymaltose) when iron status fits1
Suggested (weaker support)
- Oral iron (ferrous sulfate) and other IV iron forms1
- Dipyridamole1
- Extended-release opioids, for some people1
- A nerve-stimulation device worn on the lower legs1
Now suggested against for standard use
Ropinirole, pramipexole and the rotigotine patch (dopamine agonists) and levodopa.1 The main concern is augmentation: over months to years, symptoms gradually get stronger and last longer, may start earlier in the day, and can spread to other parts of the body.1 They may still be used short term for people who prioritize quick relief.1 Our guides to augmentation signs and new urges on ropinirole explain what to watch for.
The guideline also suggests against clonazepam and valerian, and recommends against cabergoline.1
If you already take ropinirole or pramipexole
Don’t stop suddenly. Ask your prescriber whether you have signs of augmentation and whether a gradual switch makes sense.
Try: “I’ve taken pramipexole for six years and my symptoms now start in the afternoon. Could this be augmentation, and should we check my ferritin and consider gabapentin?”
Did I Do That in My Sleep? includes a 14-Night Lights-Out Record and a Visit Brief. Use them to log what time symptoms start each day and every medicine you take. See the book.

It isn't a substitute for diagnosis or treatment from a qualified healthcare professional who knows your health history. Please don't stop or change ropinirole, pramipexole, rotigotine or any other medicine without talking to your prescriber, because stopping suddenly can worsen symptoms. Don't start iron supplements without testing, since too much iron can be harmful. If you think you may be having a medical emergency, call 911 or your local emergency number right away.
