Most people should take Lexapro for at least 6 to 12 months after their symptoms improve, not from the day they started. That timeline surprises many people, because it means the clock doesn’t really start until you feel better. Stopping too early is one of the most common reasons depression or anxiety comes back.
How Long Before It Starts Working
Lexapro doesn’t work immediately. Some early signs, like better sleep, more energy, or improved appetite, can show up within 1 to 2 weeks. But the core symptoms you’re taking it for, such as persistent low mood, loss of interest in things you used to enjoy, or constant worry, often take 6 to 8 weeks to fully improve. This is important context, because the treatment timeline builds on top of this initial ramp-up period.
The Minimum for a First Episode
If this is your first experience with depression, clinical guidelines recommend continuing Lexapro for 6 to 12 months after you reach remission. Remission means your symptoms are mostly or completely gone, not just slightly better. So if it takes 8 weeks to feel well and then you stay on for another 6 to 12 months, you’re looking at roughly 8 to 14 months total from start to finish at minimum.
This continuation phase exists because your brain needs time to stabilize. Feeling better is not the same as being recovered. A meta-analysis of antidepressant discontinuation found that roughly 35% of people relapse within 6 months of stopping, and about 45% relapse within 12 months. Those numbers apply broadly across antidepressants, including Lexapro. Staying on the medication through the full continuation phase significantly lowers that risk.
When Longer Treatment Makes Sense
If you’ve had two or more depressive episodes, or if your episodes have been severe, the recommended maintenance period extends to two years or longer. The Canadian Network for Mood and Anxiety Treatments guidelines specifically recommend this extended timeline for people with high relapse risk factors, which include:
- Multiple previous episodes: Each recurrence increases the chance of another one.
- Severe or prolonged episodes: Episodes that lasted many months or involved significant impairment.
- Residual symptoms: If you never quite got back to baseline between episodes.
- Family history: A strong family history of depression suggests a biological pattern that benefits from longer protection.
Some people with highly recurrent depression stay on Lexapro indefinitely. This isn’t a failure. It’s a practical decision, similar to taking blood pressure medication long-term when the underlying condition is chronic.
Anxiety Disorders Have a Similar Timeline
If you’re taking Lexapro for generalized anxiety disorder, the recommended treatment duration is also 6 to 12 months after your symptoms are under control. Anxiety disorders tend to follow a waxing and waning pattern, meaning symptoms can flare up even when you think you’ve turned a corner. The extended treatment window helps smooth out that cycle and reduces the chance of a return to full-blown anxiety after stopping.
Notably, the FDA prescribing information states that Lexapro’s effectiveness for anxiety beyond 8 weeks hasn’t been formally studied in controlled trials, but real-world clinical practice consistently supports longer use. The 6 to 12 month recommendation comes from broader treatment guidelines for anxiety disorders as a class.
What Happens When You’re Ready to Stop
You should never stop Lexapro abruptly. The FDA label specifically recommends a gradual dose reduction rather than sudden cessation. Stopping cold turkey can cause discontinuation syndrome, a cluster of symptoms that includes dizziness, irritability, nausea, brain zaps (brief electrical-shock sensations), and flu-like feelings. These aren’t dangerous, but they’re unpleasant and can be confused with your original condition coming back.
A typical tapering schedule involves reducing your dose by 10 to 25% every 2 to 4 weeks. For someone on 10 mg, that might look like stepping down to 7.5 mg for several weeks, then 5 mg, then 2.5 mg, then stopping. The process often takes several weeks to a few months. Below 5 mg, the risk of withdrawal symptoms increases, so many people slow their taper at that point.
Tapering is also the time when you’ll find out whether your symptoms return. If depression or anxiety comes back during the taper, that’s useful information. It may mean you need a longer course of treatment or that staying on Lexapro is the right choice for now.
Long-Term Use and Safety
Many people wonder whether staying on Lexapro for years is safe. Clinical trials during the drug’s approval tested patients for up to one year, and the FDA prescribing information recommends periodic reassessment for anyone on it long-term. In practice, millions of people take SSRIs like Lexapro for years or even decades. The known long-term side effects, such as sexual dysfunction, weight changes, and emotional blunting, are the same ones that can appear in the first few months. There isn’t strong evidence that new, serious risks emerge after years of use, though individual experiences vary.
The key principle is periodic re-evaluation. If you’ve been stable for a long time, it’s reasonable to discuss with your prescriber whether a trial off the medication makes sense. If you’ve had multiple relapses after stopping, staying on long-term may be the most practical path. Neither choice is inherently better. It depends on your history, your risk factors, and how the medication affects your daily life.
