Best Time to Take Lexapro for Anxiety: Morning or Night?
Author:
Blossom Editorial


The best time to take Lexapro (escitalopram) for anxiety is usually the time of day that keeps side effects like insomnia or drowsiness to a minimum and that you can stick with every day. The FDA label allows Lexapro to be taken once daily in the morning or evening, with or without food, so the right time often depends on how your body responds. Understanding how timing affects sleep, energy, and side effects can help you and your prescriber settle on a routine that works for you.
Key Takeaways
Timing shapes side effects, not the response timeline: Changing the time of day may help some people manage sleepiness or insomnia, but there isnโt enough evidence that morning versus evening dosing affects how quickly Lexapro works for anxiety. Lexapro reaches steady levels in the body in about a week, but anxiety relief tends to build over several weeks regardless of the time of day you take it.
Match your dose time to how you feel: Morning doses may suit people who notice trouble sleeping, while evening doses may suit people who feel drowsy or tired after taking Lexapro.
Check in before you switch: Changing when you take Lexapro is usually simple, but talk with your prescriber or pharmacist first, and never take two doses to make up for a missed one.
What is Lexapro and How Does it Help With Anxiety?
Lexapro is the brand name for escitalopram, a selective serotonin reuptake inhibitor (SSRI) antidepressant. It works by blocking the reuptake of serotonin into nerve cells by binding to the serotonin transporter protein. This increases the availability of serotonin in the space between the nerve cells, which increases serotonin signaling. Over time, this is thought to improve mood and anxiety.
Lexapro is approved to treat generalized anxiety disorder (GAD) in adults and children 7 years and older, as well as major depressive disorder in people 12 and older. SSRIs are a common medication option for anxiety disorders, and research reviews have found Lexapro effective across several anxiety conditions, including GAD, social anxiety, and panic disorder.
Lexapro is used off-label for these anxiety disorders, with the exception of GAD. Unlike some as-needed anxiety medicines, Lexapro must be taken once a day, every day, to build and maintain its effect. Lexapro can begin improving anxiety symptoms within the first few weeks, although the full benefit may take longer. In clinical trials of GAD, improvements were detectable as early as the first or second week and continued over the eight-week treatment period. However, even after sufficient therapeutic effect is achieved, you may need to continue taking a maintenance dose for a period of time recommended by the provider to prevent relapse.
If you are comparing medication choices, it may also help to learn how different SSRIs compare for anxiety.
Is it Better to Take Lexapro in the Morning or at Night?
There is no single best time to take Lexapro for anxiety. The prescribing information states it can be taken once daily in the morning or evening, with or without food. Research on antidepressants and sleep suggests that effects on sleep depend on the medication, the dose, the time it is taken, and how long treatment has lasted. With that in mind, here is how each option tends to fit different people.
Taking Lexapro in the Morning
Morning dosing is a common starting point, especially if Lexapro leaves you feeling alert or makes it harder to sleep. In adult GAD trials in which patients received 10โ20 mg/day, insomnia was reported by 12% of people taking Lexapro compared with 6% taking a placebo, so sleep changes are not unusual.
Taking Lexapro in the morning may be a good fit if you:
Notice trouble falling asleep or staying asleep after starting Lexapro
Feel more alert, restless, or wired in the hours after your dose
Already take other medications in the morning and want a single routine
Find morning habits, like making coffee or brushing your teeth, easier to remember
Taking Lexapro at Night
Some people may feel sleepy after starting Lexapro. In the same GAD trials, somnolence (sleepiness) affected 13% of people on Lexapro compared with 7% on placebo, and fatigue affected 8% of Lexapro users compared with 2% of placebo users.
If you feel tired on Lexapro, taking it in the evening may help keep that drowsiness from interfering with your day. That said, some people may still experience residual sedation during the daytime. That is why you must exercise caution with driving or operating machinery until you know how the medication affects you.
Taking Lexapro at night may be worth discussing with your prescriber if you:
Feel sleepy, foggy, or low on energy a few hours after a morning dose
Drive or do safety-sensitive work during the day
Have unpredictable mornings but a consistent bedtime routine
How Lexapro Timing Affects Side Effects
Timing will not necessarily prevent side effects, but it may make some of them easier to live with. Many side effects are most noticeable in the first few weeks and ease as your body adjusts. Here is how the most common ones relate to when you take your dose.
Sleep Changes on Lexapro
Because Lexapro can cause either insomnia or sleepiness, the way it affects your sleep is often the main reason to choose one time over another. Dose can matter too.
In two fixed-dose studies in adults with major depression, insomnia was reported by 14% of people taking 20 mg daily compared with 7% taking 10 mg. The same studies reported somnolence (daytime sleepiness) as a side effect in 4% of patients taking 10 mg compared to 9% of patients on 20 mg Lexapro.
Sleep changes are thus a dose-dependent adverse effect of Lexapro, which can swing in either direction, depending on the individual.
If sleep changes start after a dose increase, that is worth mentioning to your prescriber rather than simply moving your dose time.
Nausea and Stomach Upset
Nausea is one of the most frequently reported side effects, affecting 18% of people taking Lexapro in clinical trials for GAD compared with 8% on placebo. The label notes that absorption of escitalopram is not affected by food, so taking your dose with a meal is an option some people find more comfortable. Pairing your dose with breakfast or dinner can also make it easier to remember.
Some people find an evening dose helpful, as they can sleep through the initial nausea and gastrointestinal side effects. This may not work for everyone, though.
Other Common Lexapro Side Effects
Several other side effects appear in clinical trials, and they are not clearly linked to a particular time of day. In adult GAD trials, these included the following, compared with placebo:
Headache: 24% with Lexapro compared with 17% with placebo
Dry mouth: 9% compared with 5%
Decreased libido: 7% compared with 2%
Ejaculation disorder: 14% compared with 2%
Orgasm difficulty: 6% compared with under 1%
Increased sweating: 4% compared with 1%
Side effects can show up differently from person to person, and factors like hormones, other medications, and your dose may play a role. Women taking Lexapro may experience other side effects, too, and it is worth discussing these with your provider.
If a side effect is disrupting your routine, write down when it tends to happen relative to your dose, since that detail can help your prescriber decide whether a timing change is worth trying.
Why Consistent Lexapro Timing Matters More Than the Exact Hour
Lexapro stays in the body for a long time. Its mean terminal half-life is about 27 to 32 hours, peak blood levels occur about 5 hours after a dose, and steady levels are reached within about one week of daily dosing. Due to its long half-life, small changes in the time you take it generally cause less abrupt changes in blood levels than they would with a short-acting medication. Taking it at a consistent time can also make it easier to remember.
It is also important to set realistic expectations. In clinical trials of Lexapro for GAD, improvement was detectable as early as the first or second week and continued through eight weeks. Knowing the typical timeline for how long it takes Lexapro to work for anxiety can help you stay patient during those early weeks, when side effects may show up before the benefits do.
A few simple habits can make consistent dosing easier:
Set a recurring alarm or reminder on your phone
Pair your dose with something you already do every day, like brushing your teeth
Use a weekly pill organizer so you can see at a glance whether you took your dose
Keep your medication in a consistent, visible spot that is out of reach of children and pets
Ask your pharmacy about automatic refills so you do not run out
What to Do If You Miss a Dose of Lexapro
If you forget a dose, general guidance is to take it as soon as you remember unless it is almost time for your next dose, and never double up. Your pharmacist can walk you through what makes sense for your schedule, especially if you take Lexapro at night and remember the missed dose the next morning.
An occasional missed dose is unlikely to undo your progress, but skipping doses back-to-back or stopping suddenly can cause discontinuation symptoms like dizziness, irritability, headache, and electric shock sensations (brain zaps). These symptoms typically begin 1-3 days after stopping Lexapro. If you want to stop the medication, your prescriber can help you taper off Lexapro gradually.
How to Switch Your Lexapro Dosing Time Safely
If evening dosing is keeping you up at night or morning dosing is leaving you groggy, switching times is often reasonable. Because Lexapro has a long half-life, moving your dose forward by several hours is unlikely to cause a large immediate change in blood levels. Even so, it is a good idea to check with your prescriber or pharmacist first, since they know your full medication list and history.
Hereโs an example of how to make the switch:
Step 1: Take your current dose at the usual time, for e.g., in the morning
Step 2: The next day, skip the morning dose
Step 3: Resume the dose in the evening of the same day, and continue taking it at around the same time every day.
Note: This switch plan is only for illustration purposes; always consult your prescriber or pharmacist before switching dose timings.
Also, before you change your routine, consider these steps:
Write down why you want to switch, such as trouble sleeping or daytime drowsiness
Ask your prescriber or pharmacist how to shift the dose time without accidentally taking two doses too close together; make sure to mention your current medications so they can consider potential drug interactions
Avoid taking both a morning and an evening dose on the day you switch
Track your sleep, energy, and anxiety for a week or two so you can share what changed
When to Talk to Your Prescriber About Lexapro
Most timing questions can be handled at a routine follow-up, but some situations call for a sooner conversation. The label also advises avoiding alcohol during treatment, as drinking can worsen sleep and anxiety, and Lexapro and alcohol can interact. Reach out to your prescriber if you notice:
Insomnia or drowsiness that lasts beyond the first few weeks or affects your work or driving
Anxiety that feels worse, new panic attacks, or unusual agitation or restlessness
Little or no improvement after several weeks of taking Lexapro as prescribed, or sooner if your symptoms are worsening or side effects are difficult to manage
A combination of symptoms such as agitation or confusion, heavy sweating, fever, tremor or muscle twitching/rigidity, rapid heartbeat, or diarrhea after starting or combining serotonergic medications, which may indicate serotonin syndrome and require urgent medical care
New or worsening thoughts of suicide, especially in people 24 and younger, which the label highlights in a boxed warning
If you are having thoughts of harming yourself, call or text the 988 Suicide and Crisis Lifeline or go to your nearest emergency room.
