RLS linked to escitalopram often eases after a dose or timing change, and it often fades after stopping, though relief can take weeks.
Starting Lexapro and then feeling an urge to move your legs at night can be unsettling. When it begins right after a new prescription or a dose increase, it’s fair to suspect the medication.
This guide covers the patterns people report with SSRI-related leg restlessness, how to separate RLS from other forms of restlessness, and what tends to help.
What RLS Symptoms Usually Feel Like
Restless legs syndrome is marked by symptoms that begin or worsen during rest, ease with movement, and often flare in the evening. People describe tingling, crawling, aching, or a deep “can’t keep my legs still” urge.
Two quick checks help you label what’s going on:
- Rest trigger: Symptoms kick in after sitting or lying down, not while you’re active.
- Movement relief: Walking, stretching, or shifting positions calms the urge more than simply trying to relax.
If you want a clean definition to compare against, Mayo Clinic’s RLS symptoms and causes page lists the hallmark pattern and common triggers.
Why Lexapro Can Trigger Leg Restlessness
Lexapro (escitalopram) is an SSRI. Serotonin signaling interacts with movement and sleep circuits, so changing serotonin levels can change how “stillness” feels in the body. Some people get leg-focused symptoms that fit RLS. Others get a broader restlessness that feels more like inner motor pressure.
Because the sensations overlap, it helps to separate three buckets:
- RLS pattern: Mostly legs, mostly at rest, stronger in the evening, eased by motion.
- Akathisia-style restlessness: Whole-body urge to move that can show up during the day too.
- Sleep disruption: Insomnia can make any body sensation feel louder at night.
Escitalopram’s official labeling warns about agitation and restlessness that can occur early in treatment and after dose changes, along with sleep-related adverse reactions. FDA prescribing information for Lexapro is the most direct source for those cautions.
RLS From Lexapro: When It Fades And When It Sticks
In many cases, it does go away. A common pattern is onset soon after starting escitalopram or raising the dose, followed by gradual easing as your system adjusts. Another pattern is symptoms that stay steady until the dose is lowered, the dosing time is changed, or the medication is switched.
Typical timelines people see:
- Days to 2 weeks: New restlessness shows up, often paired with sleep changes.
- Weeks 2 to 6: Some people notice steady improvement without changing the prescription.
- After a dose increase: A flare can happen again for several days.
- After stopping: Medication-linked restlessness often fades over days to a few weeks, depending on taper pace and individual sensitivity.
If symptoms continue for months after stopping, ask about other drivers such as low iron stores or sleep apnea.
A Fast Self-Check Before You Change Anything
The medication may be a trigger, and another factor may be adding fuel. A quick self-check helps you decide what to ask for next.
Track The Pattern For Seven Nights
Each night, jot down: the time symptoms start, what you were doing right before they hit, and what brings relief. A simple note is enough. You’re looking for repeatable patterns, not perfect data.
Scan For Common Triggers
- Low iron stores (even without anemia)
- Later-day caffeine (coffee, tea, cola, energy drinks)
- Alcohol close to bedtime
- Long stretches of sitting
- Short sleep or irregular bedtimes
If you have heavy menstrual bleeding, donate blood often, eat little iron-rich food, or have absorption issues, ask about iron studies. Many RLS care pathways start by checking ferritin and iron measures because low stores can drive symptoms.
What To Do If Lexapro Is The Likely Trigger
If the timing is tight—symptoms started after beginning Lexapro or after a dose increase—bring it up early. Waiting weeks can leave you sleep-deprived and frustrated, which raises the odds of stopping medication abruptly.
Talk About Dose And Timing
Some people do better taking escitalopram in the morning, especially if the medication feels activating at night. Others do better at night if daytime drowsiness is the bigger issue. A clinician can help you try a timing change safely.
If symptoms are strong, a dose reduction is a common move. If the medication was started recently, switching to another antidepressant may be on the table. The decision depends on how well the medication is helping and how disruptive the leg symptoms are.
Know The Safety Red Flags
Get urgent care if you develop severe agitation, confusion, fever, stiff muscles, or a fast heartbeat, especially after a dose change or when mixing medications. Also get prompt help for suicidal thoughts or new self-harm urges. MedlinePlus drug information for escitalopram lists these warnings and when to seek immediate medical attention.
What Often Helps At Night While You Wait
Home steps won’t solve every case, yet they can make nights easier while you sort out the medication plan. Stick to repeatable changes so you can tell what’s working.
Use Short, Repeatable Movement
Try a 5-minute walk, then gentle calf stretches, then back to bed. If symptoms return, repeat the same sequence once. Open-ended pacing can turn into a two-hour spiral.
Test Heat Or Cold
Many people respond to a warm shower, a heating pad, or a cool pack on the calves. Pick one and test it for three nights in a row.
Set A Caffeine Cutoff
If you use caffeine daily, move your last dose earlier. A simple cutoff—no caffeine after lunch—can be a useful experiment.

Common Patterns And Practical Responses
| What You Notice | What It Often Points To | Next Step That Fits |
|---|---|---|
| Urge to move legs starts after lying down; worse at night | RLS pattern | Track timing, ask about iron studies, review triggers |
| Symptoms begin soon after starting or increasing escitalopram | Medication-triggered symptoms | Ask about dose or timing change, plan a slow taper if needed |
| Whole-body inner agitation with daytime pacing | Akathisia-style restlessness | Tell the prescriber the same day if severe |
| Symptoms flare after long sitting (desk, travel) | Rest worsens symptoms | Movement breaks, calf stretches, earlier bedtime |
| Symptoms spike after alcohol near bedtime | Common RLS trigger | Shift alcohol earlier or skip for a week to test the effect |
| Symptoms improve, then return after a dose increase | Sensitivity to titration speed | Ask about smaller dose steps or more time between increases |
| Heavy bleeding, frequent blood donation, or low-iron diet | Iron depletion risk | Ask for ferritin and iron measures, then recheck after treatment |
| One-sided swelling, calf pain, or sudden weakness | Needs urgent rule-out | Seek same-day medical assessment |
How Clinicians Treat Ongoing RLS Symptoms
If symptoms don’t settle with time or a medication adjustment, clinicians often start with iron studies and a medication review. Treatment choices are shaped by updated guideline work that weighs relief against longer-term tradeoffs.
The American Academy of Sleep Medicine released updated treatment recommendations and summarizes the main themes for the public. AASM’s guideline summary for RLS treatment gives a current snapshot of the direction of care.
Iron Repletion When Stores Are Low
Low iron stores can worsen RLS even when hemoglobin is normal. Treatment can be oral or intravenous, depending on severity and tolerance. Follow-up lab checks matter because iron can overshoot.
Medication Options When Iron Is Not The Issue
Clinicians may use medications that reduce sensory symptoms or calm nerve signaling during rest. The choice depends on your medical history, other medications, and side-effect profile. If an SSRI is part of the trigger, your prescriber may weigh switching antidepressants against adding an RLS-focused medication.

Timelines People Ask About Most
| Situation | Common Time Course | What Often Helps |
|---|---|---|
| New symptoms after starting escitalopram | Days to first 2 weeks | Track nights, home steps, ask about timing |
| Symptoms after a dose increase | First week after change | Smaller dose steps or more time between increases |
| Nightly symptoms still strong after 4–6 weeks | Often persists unless adjusted | Iron studies, medication review, RLS treatment plan |
| Symptoms after tapering off escitalopram | Days to a few weeks | Gradual taper and consistent sleep schedule |
| Symptoms months after stopping | Less common; suggests another driver | Full RLS work-up and screening for sleep apnea |
How To Describe Symptoms In A Clinician Visit
RLS can get mislabeled as general anxiety or “stress,” especially when it starts during antidepressant treatment. A tight description keeps the visit on track.
- Pattern: “Urge to move my legs starts after I lie down and eases when I walk.”
- Start date: “It began three days after starting 10 mg,” or “two days after increasing.”
- Sleep cost: “I’m sleeping four hours a night,” or “I’m up for an hour, twice.”
- Two asks: “Can we check ferritin?” and “Can we adjust dose or timing?”
If you’re worried about stopping suddenly, say that plainly. A clinician can map out a taper that reduces withdrawal risk.
A Simple Night Plan To Start Tonight
- Two hours before bed: Skip alcohol. Move caffeine earlier in the day.
- Thirty minutes before bed: Warm shower or heat on calves.
- At lights out: If symptoms hit, do a 5-minute walk plus gentle calf stretches.
- Back in bed: Keep the room cool and dark. Use a pillow between knees if it helps.
- If symptoms return: Repeat the same 5-minute routine once, then try to rest again.
Run the plan for seven nights, then bring your notes to your next appointment.
When The Best Move Is A Medication Change
If nights are still rough after several weeks, or if symptoms are severe from day one, it’s reasonable to revisit the Lexapro plan. Many people land in one of these outcomes:
- Adjust and stay: A timing or dose tweak makes symptoms tolerable.
- Switch meds: Sleep loss outweighs the benefit, so a different antidepressant is tried.
- Treat RLS directly: Iron therapy or an RLS medication is added when the antidepressant benefit is strong.
The goal is simple: steady sleep and a plan you can follow.
