Lexapro (escitalopram) is taken once daily by mouth, with or without food, at whatever time of day works best for you. The standard dose for most adults is 10 mg once daily, and food does not affect how your body absorbs the medication. Beyond that simple instruction, there are practical details about timing, what to expect in the first few weeks, and how to handle common situations like missed doses that make a real difference in your experience.
Morning or Evening: Choosing Your Time
There’s no single “correct” time of day to take Lexapro. The best approach is to pick a consistent time and stick with it. That said, the side effects you experience in the first couple of weeks can help you decide.
If Lexapro makes you feel drowsy or fatigued during the day, switch to taking it at bedtime. If it causes insomnia or makes it harder to fall asleep, take it in the morning instead. Many people start by taking it in the morning and adjust from there. The key is consistency: taking it at roughly the same time each day keeps a steady level of the medication in your system.
With or Without Food
Lexapro’s absorption is not affected by food, so you can take it on an empty stomach or with a meal. If the medication causes mild nausea early on (a common side effect in the first week or two), taking it with food or a snack can help settle your stomach. You can also take it with water, juice, or whatever you’re drinking. There are no specific foods you need to avoid.
Tablet and Liquid Forms
Lexapro comes as a tablet and as an oral solution. The liquid form contains 1 mg per milliliter (5 mg per 5 mL teaspoon), which is useful for people who have trouble swallowing pills or need doses between standard tablet sizes. If you’re using the liquid, measure your dose with a proper oral syringe or measuring device rather than a kitchen spoon, since household spoons vary in size and can lead to inaccurate dosing.
Standard Dosing for Adults
For both depression and generalized anxiety disorder, the recommended starting dose is 10 mg once daily. If needed, your prescriber may increase the dose to 20 mg, which is the maximum. That increase typically happens after at least one week on 10 mg. Clinical trials found that 20 mg didn’t consistently show greater benefit over 10 mg for depression, so many people do well staying at the lower dose.
For adolescents (ages 12 to 17) being treated for depression, the starting dose is also 10 mg daily, but any increase to 20 mg should wait at least three weeks rather than one.
How Long It Takes to Work
Lexapro begins raising serotonin levels in the brain within hours, but you won’t feel a meaningful difference that quickly. The earliest signs that it’s working, like improved sleep, more energy, or a better appetite, can appear within one to two weeks.
The deeper emotional symptoms take longer. Relief from persistent sadness, loss of interest in things you used to enjoy, or chronic worry may take six to eight weeks to fully improve. This is one of the most important things to know: if you don’t feel much different after two or three weeks, that doesn’t mean the medication isn’t working. Give it the full timeline before deciding it’s not helping.
What to Do If You Miss a Dose
If you realize you forgot your dose, take it as soon as you remember. If it’s already close to the time for your next dose, skip the missed one and continue with your regular schedule. Don’t take two doses at once to make up for it. Missing a single dose occasionally is unlikely to cause problems, but skipping multiple days in a row can trigger uncomfortable withdrawal-like symptoms, so try to stay as consistent as possible.
Alcohol and Lexapro
Alcohol and Lexapro are a poor combination for several reasons. Both can cause drowsiness on their own, and together the sedating effect becomes significantly stronger, impairing your judgment, coordination, and reaction time more than alcohol alone would. Alcohol also works against the medication itself: it can worsen depression and anxiety symptoms and reduce Lexapro’s therapeutic benefit, making your condition harder to treat. If you do drink, keeping it minimal is the safest approach.
Serotonin Syndrome: A Rare but Serious Risk
Serotonin syndrome is an uncommon but potentially dangerous reaction that can happen when too much serotonin builds up in the body. The risk increases when Lexapro is combined with other medications that also raise serotonin levels, including certain migraine drugs (triptans), some pain medications, St. John’s wort, and other antidepressants.
Symptoms develop relatively quickly and include agitation or restlessness, rapid heartbeat, sweating, dilated pupils, muscle twitching or rigidity, and diarrhea. Severe cases can cause high fever and seizures. If you develop these symptoms, especially a combination of them, it requires immediate medical attention. The simplest way to reduce this risk is to make sure every prescriber you see knows you’re taking Lexapro.
Why You Should Never Stop Abruptly
Stopping Lexapro suddenly can cause a set of withdrawal symptoms known as discontinuation syndrome. Common symptoms include “brain zaps” (brief electric shock-like sensations in the head), fatigue, excessive sleepiness, irritability, and dizziness. These aren’t dangerous, but they’re unpleasant enough that most people want to avoid them.
The standard approach is to taper gradually, reducing your dose in steps over weeks rather than stopping all at once. Some people, especially those who’ve had withdrawal symptoms from antidepressants before, benefit from a slower, more gradual taper. One case study documented a successful approach that reduced the dose from 10 mg in progressively smaller steps (5 mg, 3 mg, 1.5 mg, 1 mg, 0.5 mg, 0.25 mg) before stopping entirely, with each reduction about a week apart. Your prescriber can adjust the speed of your taper based on how you’re responding. The important thing is to not make changes to your dose on your own.
