Common Withdrawal Symptoms from Stopping Lexapro
Lexapro (escitalopram), an SSRI antidepressant, can cause discontinuation syndrome when stopped abruptly. Symptoms often start within 1-3 days and peak around day 5, lasting 1-3 weeks in most cases.[1] They affect up to 50% of users who quit suddenly, but tapering reduces risk.[2]
Key symptoms include:
- Dizziness or vertigo (most common, described as "brain zaps" or electric shock sensations).
- Nausea, vomiting, or diarrhea.
- Fatigue, lethargy, or flu-like aches.
- Irritability, anxiety, or mood swings.
- Insomnia or vivid dreams.
- Headache or sensory disturbances like tingling.[1][3]
Why Does Lexapro Cause These Symptoms?
SSRIs like Lexapro increase serotonin levels. Sudden stops disrupt this balance, leading to a rapid drop in serotonin signaling. Lexapro's long half-life (27-32 hours) delays onset compared to shorter-acting SSRIs, but symptoms hit harder due to its potency.[2][4]
How Long Do Symptoms Last?
Duration varies by dose, duration of use, and taper speed. Mild cases resolve in days; severe ones last weeks. Long-term users (over 6 months) face higher risk. About 20% report symptoms persisting over 3 weeks.[3][5]
What Happens If You Stop Abruptly vs. Tapering?
Abrupt cessation multiplies symptom severity—up to 86% incidence vs. 38% with gradual taper.[2] Doctors recommend tapering over 4-8 weeks (e.g., reduce 5mg every 1-2 weeks), sometimes switching to longer-half-life fluoxetine for smoother exit.[1][4]
Risk Factors and Who Gets Hit Hardest
Higher risk with:
- Daily doses over 20mg.
- Use longer than 8 weeks.
- History of prior withdrawal or sensitivity to meds.[3]
Kids and elderly may experience amplified effects; pregnant users face fetal risks if untreated.[5]
How to Manage or Prevent Withdrawal
- Taper under medical supervision—never quit cold turkey.
- Symptom relief: Restart low dose temporarily, use anti-nausea meds, or short-term benzos for anxiety (with caution).[1]
- Lifestyle: Hydrate, rest, avoid caffeine/alcohol; exercise helps some.[4]
Seek ER if suicidal thoughts or severe disorientation emerge.[2]
When to Call Your Doctor
Contact if symptoms worsen after taper, include confusion/seizures, or mimic relapse (e.g., returning depression).[3] Not all feel it—genetics play a role.[5]
