There is no set maximum duration for taking Lexapro. Many people take it for years, and some stay on it indefinitely. The right timeline depends on your diagnosis, how many episodes of depression or anxiety you’ve had, and how well you tolerate the medication. Most guidelines recommend a minimum of 6 to 12 months after your symptoms improve, but beyond that, the decision is individualized.
The Minimum Recommended Duration
One of the most common mistakes with Lexapro is stopping too early. Feeling better after a few months can make it tempting to quit, but that improvement is often the medication working, not a sign that the underlying condition has resolved. Clinical guidelines recommend continuing for at least 6 to 12 months after you’ve reached a good response. Stopping before that one-year mark leads to symptom relapse in up to 50% of patients on SSRIs. Even among those who stay on medication, about 16% still experience a relapse, which gives you a sense of how persistent these conditions can be.
When Long-Term Use Makes Sense
For a first episode of depression or anxiety that responds well to treatment, a trial of 6 to 12 months followed by a slow taper is a reasonable plan. But if you’ve had two or more episodes of depression, or if your symptoms were severe, most clinicians recommend staying on medication much longer, potentially for years or indefinitely.
A large study from University College London tracked patients who had been on antidepressants long-term and then either continued or stopped. Over the following year, 56% of those who discontinued experienced a new episode of depression, compared to 39% of those who kept taking their medication. That gap matters. For people with recurrent depression, long-term Lexapro isn’t just a safety net; it meaningfully lowers the odds of another episode.
What Happens to Effectiveness Over Time
Some people notice that Lexapro seems to work less well after months or years. This isn’t imagined. It’s sometimes called antidepressant “poop-out,” and it affects roughly 25% of patients on antidepressants, with estimates for SSRI users specifically ranging from 9% to 33%. Some research puts the upper end even higher.
If this happens, it doesn’t necessarily mean Lexapro has permanently stopped working. Common strategies include adjusting the dose, adding a second medication, or switching to a different antidepressant altogether. The key is recognizing it and talking to your prescriber rather than assuming you just have to live with a partial response.
Weight Changes With Long-Term Use
Lexapro is on the lighter end of antidepressants when it comes to weight gain, but it isn’t neutral. On average, patients gain about 1.4 pounds at six months and 3.6 pounds at two years. That’s modest compared to some other options, though individual experiences vary widely. If weight is a concern, it’s worth monitoring over time rather than assuming the medication won’t have any effect.
Sexual Side Effects
Sexual side effects are common with SSRIs and are one of the main reasons people want to stop taking them. Reduced desire, difficulty with arousal, or trouble reaching orgasm can occur at any point during treatment. For most people, these effects resolve after stopping the medication. In rare cases, however, sexual dysfunction persists even after discontinuation. Australia’s drug safety authority identified hundreds of case reports of persistent sexual dysfunction linked to SSRIs, with escitalopram among the most commonly implicated medications. The effects in those reports lasted from 12 months to over 3 years after stopping. This outcome is considered rare, but it is likely underreported.
How to Stop Safely
Lexapro carries a moderate risk of discontinuation syndrome, meaning your body can react to a sudden drop in the medication. Symptoms typically start within two to four days of stopping and can include dizziness, nausea, flu-like achiness, vivid dreams, and electric shock-like sensations. Mood changes like irritability and heightened anxiety are also common. Most people recover within a few weeks, but about 7% still have symptoms at two months, and a small percentage (around 2%) report symptoms lasting beyond three years.
The way to minimize this is a gradual taper. A common approach is reducing your dose by 10% to 25% every two to four weeks. For someone on 10 mg, that might look like stepping down to 7.5 mg, then 5 mg, then 2.5 mg, with each step lasting several weeks. The lower you go, the slower you should taper, because withdrawal symptoms tend to be more pronounced at the smallest doses. A full taper can take weeks to months depending on how long you’ve been on the medication and how sensitive you are to changes. Never stop abruptly.
Deciding What’s Right for You
The question isn’t really whether you “can” take Lexapro long-term. You can. The better question is whether the benefits still outweigh the downsides for your specific situation. If your depression or anxiety has been a one-time episode and you’ve been stable for a year, a carefully managed taper may be worth trying. If you’ve had multiple episodes, or if previous attempts to stop led to relapse, staying on the medication is a valid and well-supported choice. There’s no penalty for long-term use beyond the side effects you’re already experiencing.
The strongest predictor of whether you should stay on Lexapro is your own history. People with three or more depressive episodes, those whose first episode was severe, and those with a family history of mood disorders tend to benefit most from open-ended treatment. Revisiting the decision periodically with your prescriber, rather than picking an arbitrary stop date, gives you the best shot at staying well.
