Starting an antidepressant often comes with two questions: When will I feel better, and how will I know the medication is working? Waiting can be frustrating, especially when symptoms of depression or anxiety are affecting your sleep, relationships, or daily routine.

So, how long does Lexapro take to work? Some people notice early changes in sleep, appetite, or energy within one to two weeks. Improvements in mood, anxiety, motivation, and interest in activities often take four to eight weeks. The timing varies, and some people need longer before they experience the medication’s full benefit.

Lexapro, the brand name for escitalopram, is a selective serotonin reuptake inhibitor, or SSRI. The U.S. Food and Drug Administration has approved it to treat major depressive disorder and generalized anxiety disorder in certain adults and children.

What to Expect During the First Few Weeks

Lexapro does not usually produce immediate relief. During the first one or two weeks, you may notice that you are sleeping or eating more normally, have slightly more energy, or find daily tasks easier to complete. These early changes may occur before your mood improves.

Depressed mood, persistent worry, loss of interest, and difficulty concentrating may take six to eight weeks to improve more fully. Keep taking Lexapro exactly as prescribed while your healthcare provider evaluates your response. Do not increase the dose, skip doses, or stop treatment because you have not noticed an immediate change.

Your progress may depend on the condition being treated, the prescribed dose, other medications, side effects, and whether doses are taken consistently. Contact your healthcare provider if your symptoms have not improved after several weeks or if they are getting worse.

Common side effects

Side effects can begin before Lexapro’s benefits become noticeable. Common reactions include nausea, insomnia, sleepiness, fatigue, increased sweating, diarrhea, dizziness, and sexual difficulties. Some early side effects become less noticeable as the body adjusts, but persistent or disruptive symptoms should be discussed with a healthcare provider.

Cautions and interactions

Tell your prescriber and pharmacist about every prescription medication, over-the-counter product, vitamin, and herbal supplement you take. Lexapro can interact with other medications that affect serotonin, including certain migraine medicines, tramadol, lithium, buspirone, amphetamines, and St. John’s wort. Blood thinners and antiplatelet drugs may increase bleeding risk when combined with Lexapro.

Adults age 65 and older, along with people taking diuretics, may have a higher risk of hyponatremia, or low blood sodium. Symptoms can include confusion, weakness, difficulty concentrating, headache, and unsteadiness.

Contraindications

Lexapro should not be taken with monoamine oxidase inhibitors, commonly called MAOIs, or within the required waiting period before or after using an MAOI. It is also contraindicated for people taking pimozide or those with a known allergy to escitalopram or citalopram.

Can you overdose on Lexapro?

Yes, you can overdose on Lexapro. A suspected overdose requires immediate help, even when the person initially appears well. Reported complications include seizures, loss of consciousness, dangerous heart rhythm changes, and serotonin syndrome.

In the United States, call Poison Help at 1-800-222-1222 after a possible overdose. Call 911 immediately if the person collapses, has a seizure, has difficulty breathing, or cannot be awakened.

Filling a Lexapro Prescription Through Canada Drugs Direct

Canada Drugs Direct lists prescription-only brand-name Lexapro and generic escitalopram in several strengths. The company states that licensed pharmacists review orders before medications are dispensed. Availability, pricing, and the dispensing location may vary, so review the current product information when placing an order.

Online ordering does not replace regular medical follow-up. Continue attending appointments so your healthcare provider can review symptom changes, side effects, interactions, and whether treatment remains appropriate.

Do not stop or change Lexapro without speaking with your healthcare provider. Stopping suddenly can cause withdrawal symptoms, so the dose is generally reduced gradually when treatment is discontinued.

Seek prompt help for new or worsening suicidal thoughts, severe agitation, or sudden behavior changes. People in the United States can call or text 988 for free, confidential crisis support. Call 911 when there is immediate danger.

Does Lexapro work immediately?

No. Early changes in sleep, energy, or appetite may appear within one or two weeks, but broader improvements in depression or anxiety commonly require several weeks. Full benefit may take six to eight weeks for some people.

Can Lexapro make you feel worse at first?

Some people experience nausea, restlessness, sleep changes, or increased anxiety when beginning treatment. Contact your healthcare provider if these symptoms are severe, persistent, or accompanied by worsening depression or suicidal thoughts.

What should I do if Lexapro is not working after eight weeks?

Speak with your healthcare provider. They may review how consistently you are taking it, your dose, side effects, other medications, and whether a different treatment approach should be considered. Do not change the dose on your own.

Can you stop Lexapro after you begin feeling better?

Do not stop Lexapro without medical guidance. Abrupt discontinuation can cause dizziness, anxiety, irritability, nausea, sleep problems, and other withdrawal symptoms. Your provider can create an appropriate gradual reduction plan.
