Getting off Lexapro typically takes anywhere from a few weeks to several months, depending on your dose, how long you’ve been taking it, and how your body responds to each reduction. There is no single timeline that works for everyone, but most tapering schedules involve gradual dose cuts over at least four to six weeks, with some people needing six months or longer.
How the Drug Leaves Your Body
Escitalopram, the active ingredient in Lexapro, has a half-life of about 27 to 31 hours in most adults. That means after you take your last dose, roughly half the drug is gone in just over a day. For older adults, the half-life stretches to around 41 hours. After about five to six half-lives, the drug is essentially cleared from your system, which works out to roughly six to eight days after your final dose.
But “cleared from your system” and “done adjusting” are two very different things. Your brain has been operating with extra serotonin activity for as long as you’ve been on the medication. Once the drug is gone, your brain needs time to recalibrate, and that adjustment period is where withdrawal symptoms come in. Discontinuation symptoms typically start once 90% or more of the drug has left your system, which usually means within a few days of stopping or reducing your dose.
What a Typical Taper Looks Like
The FDA recommends a gradual dose reduction rather than abrupt cessation. A common approach is to cut the dose in steps every one to two weeks, giving your body time to adjust at each level before dropping again. Someone on 20 mg might step down to 15, then 10, then 5 before stopping. At that pace, the taper alone takes about four to eight weeks.
A newer method called hyperbolic tapering takes a different approach. Instead of cutting the same number of milligrams each time, each step reduces the drug’s actual effect on your brain by a consistent percentage, roughly 10% per step. In practice, this means the dose reductions get smaller as you go lower. One documented case of this approach with escitalopram went from 10 mg down through 5, 3, 1.5, 1, 0.5, and finally 0.25 mg before stopping entirely. This method can take longer, but it tends to produce fewer withdrawal symptoms because the brain experiences a more even, gradual change at each step.
How Long Withdrawal Symptoms Last
Withdrawal symptoms can include dizziness, irritability, anxiety, headaches, nausea, insomnia, and a distinctive “brain zap” sensation that feels like a brief electric shock in your head. These symptoms emerge within days to weeks of a dose reduction or your final dose.
For most short-term users (those on the medication for less than six months), withdrawal symptoms resolve in under four weeks. That’s the straightforward scenario.
The picture changes significantly for long-term users. People who have taken antidepressants for more than two years face roughly 10 times the odds of experiencing withdrawal effects compared to those who used them for less than six months. Among long-term users, 30% report symptoms lasting more than three months, and about 12% experience them for over a year. Long-term users also tend to have more severe symptoms and are less likely to successfully discontinue on their first attempt.
Why Your Timeline May Be Different
Several factors influence how long the process takes for you specifically. Your current dose matters: someone tapering from 5 mg has a shorter road than someone on 20 mg. How long you’ve been on the medication is probably the single biggest predictor of difficulty. Your age plays a role too, since older adults clear the drug more slowly.
Your prescriber may also adjust the pace based on how you respond. The FDA’s prescribing information notes that if intolerable symptoms appear after a dose reduction, the previous dose can be resumed and the taper restarted at a slower rate. This back-and-forth is normal and doesn’t mean the process has failed. It just means your particular brain needs a gentler slope.
Realistic Timelines by Situation
- On Lexapro for under 6 months, low dose: A taper of 2 to 4 weeks is often sufficient, with withdrawal symptoms resolving within a few weeks of the final dose.
- On Lexapro for 6 months to 2 years, moderate dose: A taper of 4 to 8 weeks is typical. Withdrawal symptoms may linger for a few weeks to a couple of months.
- On Lexapro for over 2 years: A slower taper over 2 to 6 months (or longer) is often recommended. Withdrawal symptoms can persist for months, and a hyperbolic tapering approach may reduce their severity.
Stopping Abruptly vs. Tapering
Quitting Lexapro cold turkey is not recommended. The FDA specifically warns that abrupt discontinuation can cause serious symptoms including mood changes, confusion, sensory disturbances, and agitation. While these effects are generally self-limiting, meaning they resolve on their own eventually, they can be intense enough to interfere with daily life and are sometimes mistaken for a relapse of the original depression or anxiety.
The distinction between withdrawal and relapse matters. Withdrawal symptoms tend to appear within days of a dose change, often include physical symptoms like dizziness and brain zaps that weren’t part of the original condition, and generally improve over time. A relapse typically develops more gradually, over weeks, and looks like a return of the original mood symptoms. If symptoms persist beyond a month after your last dose and are getting worse rather than better, that pattern is more consistent with relapse than withdrawal.
