If you accidentally took two Lexapro pills, stay calm. Escitalopram has a half-life of 27 to 32 hours, which means your body processes it slowly and steadily. A single accidental double dose at typical prescribed levels is unlikely to cause serious harm. Skip your next scheduled dose and resume your normal schedule after that.
Below, the details.
Why a double dose of Lexapro is usually low risk
Lexapro (escitalopram) is one of the most commonly prescribed SSRIs in the United States, and doctors prescribe it across a range of doses. The FDA-approved maximum is 20 mg per day. Common prescribed doses include 5, 10, and 20 mg.
Two things work in your favor here. First, escitalopram's long half-life of 27 to 32 hours means your body does not experience a sharp spike when you take an extra dose. The medication is absorbed and metabolized gradually. Second, the dose range is relatively narrow. If you are taking 10 mg and accidentally doubled to 20 mg, you are at the FDA-approved maximum, not above it.
A toxicology review found that escitalopram has a wide therapeutic index and that outcomes from overdoses involving escitalopram alone were generally favorable, with most patients experiencing only mild symptoms.
If you accidentally doubled a typical dose, here is how that compares:
| Your prescribed dose | You accidentally took | Max approved daily | How it compares |
|---|---|---|---|
| 5 mg | 10 mg | 20 mg | Well within approved range |
| 10 mg | 20 mg | 20 mg | At the max approved dose |
| 20 mg | 40 mg | 20 mg | Twice the max, call your doctor |
For most people taking 5 or 10 mg, a single accidental double dose keeps you at or below the dose other patients take every day. That is genuinely reassuring.
What to do right now
- Stay calm. A single double dose of Lexapro at typical prescribed levels is manageable.
- Skip your next scheduled dose. Resume your regular schedule the day after that. Escitalopram's long half-life means the extra medication will clear gradually on its own.
- Stay hydrated. Drink water throughout the day.
- Avoid alcohol. Both Lexapro and alcohol affect your central nervous system. Combining them can amplify side effects like drowsiness and dizziness.
- Write down the time and amount you took. This is helpful information if you need to call your doctor or pharmacist.
- Do not make yourself vomit. A single double dose does not warrant this, and self-induced vomiting can cause other problems.
Symptoms to watch for
Mild symptoms (usually pass on their own)
These are common side effects of escitalopram that may be more noticeable after a double dose:
- Nausea
- Drowsiness or fatigue
- Dizziness
- Headache
- Trouble sleeping
These typically resolve as the extra drug clears your system. With a half-life of 27 to 32 hours, most of the excess should be out of your bloodstream within 2 to 3 days.
Serious symptoms (call your doctor)
Contact your doctor or pharmacist if you experience:
- Significant nausea or vomiting that does not ease up
- Heart palpitations or irregular heartbeat (escitalopram can affect heart rhythm at higher doses)
- Unusual agitation, restlessness, or confusion
- Muscle twitching or tremors
Emergency symptoms (call 911)
Call 911 if you experience:
- Seizures
- Loss of consciousness
- Severe difficulty breathing
- Very rapid or irregular heartbeat
- Signs of serotonin syndrome: high fever, severe muscle rigidity, and rapid changes in heart rate or blood pressure occurring together
Serotonin syndrome from a single accidental double dose of Lexapro alone is extremely rare. It is far more likely when SSRIs are combined with other serotonergic drugs (certain migraine medications, other antidepressants, or supplements like St. John's Wort). Still, know the signs.
When to call your doctor or Poison Control
For most people on 5 or 10 mg, a single accidental double dose does not require emergency intervention. But contact a professional if:
- You took more than one extra dose (three pills instead of one, for example)
- You take other serotonergic medications (MAOIs, triptans, tramadol, lithium, other SSRIs or SNRIs, St. John's Wort)
- You are on 20 mg and doubled to 40 mg. This puts you well above the approved maximum.
- You notice any serious or emergency symptoms listed above

How to prevent accidental double dosing
The most common scenario: you take your Lexapro, get distracted, and 20 minutes later you cannot remember whether you actually took it. Because Lexapro is a once-daily medication, this "did I or didn't I?" moment can happen on any given morning or evening. A few approaches that solve this:
Track every dose with a medication reminder app
Regular phone alarms tell you when to take a pill, but they do not record whether you actually did. A dedicated tracking app logs every confirmed dose, so you always have a clear answer to "did I already take this?"
Pillo tracks every dose you confirm, uses persistent alarms that will not stop until you respond, and keeps a history of exactly what you took and when. If you are taking Lexapro alongside other medications, that dose log becomes your safety net against double dosing.
Use a weekly pill organizer
A 7-day organizer with AM/PM compartments gives you instant visual confirmation. Compartment empty? You took it. Compartment full? Take it now.
Take Lexapro at the same time every day
Consistency makes it harder to forget or lose track. If you are deciding between morning and evening dosing, our guide on the best time to take Lexapro breaks down the pros and cons of each.
Build it into an existing habit
Pair your Lexapro with something you already do every day, like your morning coffee or brushing your teeth at night. Learn more about this approach in our medication routine guide.
Frequently asked questions
Is a double dose of Lexapro dangerous?
For most people at typical doses (5 to 10 mg), a single accidental double dose is not dangerous. Even doubling from 10 mg to 20 mg only brings you to the FDA-approved maximum. The risk increases if you are already on 20 mg and double to 40 mg, or if you take other serotonergic medications. In those cases, call your doctor.
Can a double dose of Lexapro cause serotonin syndrome?
Serotonin syndrome from a single accidental double dose of Lexapro alone is extremely unlikely. This condition is far more common when SSRIs are combined with other drugs that raise serotonin levels, such as MAOIs, triptans, tramadol, or St. John's Wort. If you take any of those alongside Lexapro, contact your doctor after a double dose.
Should I skip my next dose of Lexapro after doubling up?
Yes. Skip the next scheduled dose, then resume your regular schedule. Escitalopram's long half-life of 27 to 32 hours means skipping one dose will not cause withdrawal symptoms. Do not stop taking Lexapro entirely without talking to your doctor. For what to do on a day you missed a dose instead of doubling, see our guide on a missed dose of Lexapro.
How long until the extra Lexapro wears off?
Escitalopram has a half-life of 27 to 32 hours. Most of the extra dose should clear your system within 2 to 3 days. Any mild side effects (nausea, drowsiness, headache) should improve gradually over that period.
What is the difference between Lexapro and other SSRIs for double dosing?
Lexapro (escitalopram) has a half-life of 27 to 32 hours, which is similar to sertraline (about 26 hours). Both are relatively forgiving for an accidental double dose because the drug is processed slowly. Fluoxetine (Prozac) has an even longer half-life of 1 to 3 days, making it the most forgiving SSRI in a double-dose scenario. For comparison, see our guide on accidentally doubling sertraline.
What if I am not sure whether I already took my Lexapro?
If you genuinely cannot remember, it is safer to skip that dose than to risk doubling up. Missing one dose of Lexapro is unlikely to cause withdrawal symptoms because of its long half-life. For more guidance on this exact situation, read our guide on what to do when you cannot remember if you took your medication.
