There is no set time limit for taking Lexapro. Many people take it for years, and some take it indefinitely. The right duration depends on your diagnosis, how many depressive or anxiety episodes you’ve had, and how well you’re doing on the medication. Most guidelines recommend staying on an antidepressant for at least 6 to 12 months after symptoms improve, but plenty of people continue well beyond that.
Short-Term vs. Maintenance Use
For a first episode of depression or generalized anxiety, the typical recommendation is to keep taking Lexapro for 6 to 12 months after you start feeling better. This period is called maintenance, and it exists because stopping too early significantly raises your odds of relapse. In one study of people with social anxiety disorder, 50% of those switched to a placebo relapsed, compared to just 22% of those who stayed on escitalopram. The risk of relapse in the group that stopped was nearly three times higher.
After that initial maintenance window, your prescriber will reassess. If this was your first episode and you’ve been stable, tapering off may be a reasonable option. If you’ve had two episodes, the decision becomes more individualized. If you’ve had three or more episodes of major depression, the evidence more clearly supports staying on medication long term, potentially for life. The American Psychological Association notes there is no strong consensus on who needs indefinite treatment beyond that three-episode threshold.
What Happens to Your Body Over Years of Use
Lexapro doesn’t damage your liver, kidneys, or other organs with long-term use in the way that some medications can. It hasn’t been linked to the kind of cumulative toxicity that would put a ceiling on how long you can take it. That said, it’s not consequence-free over time.
Weight gain is one of the most common long-term effects. A large study tracking first-time antidepressant users found that escitalopram led to an average gain of about 1.4 pounds at six months and 3.6 pounds at two years. That’s modest compared to some other antidepressants, but it can add up over many years, particularly if combined with other lifestyle factors.
Emotional blunting is another concern that tends to surface with extended use. Somewhere between 40% and 60% of people on SSRIs report feeling emotionally flattened, describing a reduced ability to feel both positive and negative emotions. For some, this feels like a worthwhile trade-off. For others, it becomes the reason they want to stop. A research team at the University of Cambridge confirmed that escitalopram directly affects how people process rewards and emotional feedback, which helps explain why this blunting occurs.
Can Lexapro Stop Working Over Time?
Yes, and it’s more common than many people realize. Sometimes an antidepressant that worked well for months or years gradually loses its effectiveness. This phenomenon, sometimes called tachyphylaxis or antidepressant tolerance, isn’t fully understood. Researchers don’t know why it happens to some people and not others. If you notice your symptoms creeping back despite consistent use, that’s worth discussing with your prescriber. Options typically include adjusting the dose, adding a second medication, or switching to a different antidepressant altogether.
What Stopping Feels Like
Whenever you do decide to stop, how you taper matters enormously. Lexapro affects serotonin activity in your brain, and abrupt withdrawal can trigger a cluster of uncomfortable symptoms known as discontinuation syndrome. These typically start within two to four days of your last dose and can include dizziness, nausea, flu-like achiness, vivid or disturbing dreams, brain zaps (brief shock-like sensations), and mood swings like irritability or heightened anxiety.
Most cases resolve within a few weeks, but not all. One study found that 7% of people still had discontinuation symptoms at two months, 6% at one year, and 2% beyond three years. The FDA recommends a gradual dose reduction rather than stopping abruptly, though the prescribing information doesn’t specify an exact schedule.
How to Taper Safely
Standard practice is to cut your dose in steps over several weeks, but a growing body of evidence suggests that the final reductions need to be especially slow. Because of how SSRIs bind to receptors in the brain, going from 5 mg to zero is a much bigger biological jump than going from 10 mg to 5 mg. A case report published in a peer-reviewed journal described a successful taper from 10 mg using a series of weekly reductions: 5 mg, then 3 mg, 1.5 mg, 1 mg, 0.5 mg, and finally 0.25 mg before stopping entirely. Each step reduced serotonin receptor activity by roughly 10%, which kept withdrawal symptoms manageable.
This kind of gradual approach is especially important if you’ve been on Lexapro for years. The longer you’ve taken it, the more your brain has adapted to its presence, and the more time it generally needs to readjust. If you try tapering and develop symptoms that feel intolerable, going back to your previous dose and then reducing more slowly is a standard and safe strategy. There’s no penalty for taking longer to come off the medication.
Staying On vs. Coming Off
The decision to continue or stop Lexapro isn’t one-size-fits-all, and it doesn’t have to be permanent. Some people use it for a year, taper off successfully, and never need it again. Others try stopping, relapse within months, and decide that staying on indefinitely is the better choice for their quality of life. Both paths are medically reasonable.
If you’ve been stable for a long time and are curious about life without the medication, the key factors to weigh are how many episodes you’ve had, how severe they were, and how much your current stability depends on the drug versus other changes you’ve made (therapy, exercise, stress reduction). People with a single mild-to-moderate episode and strong coping tools are generally better candidates for discontinuation than those with a history of recurrent, severe episodes.
