What is Lexapro, and How Does It Work?

Lexapro (escitalopram) is a selective serotonin reuptake inhibitor (SSRI) that's commonly prescribed to treat depression and anxiety disorders. According to the National Alliance on Mental Illness (NAMI), it works by increasing the amount of serotonin available in the brain, a neurotransmitter that helps regulate mood, emotions, and stress responses. Because these changes happen gradually, it can take time before you notice the full effects of treatment.

The time it takes for Lexapro treatment to start taking effect can vary. It's common for some symptoms, like improved energy, sleep, and appetite, to improve within a week or two. However, other symptoms, like being uninterested in activities and having depressive feelings, might take up to 6–8 weeks before seeing improvement.

How fast does Lexapro work for anxiety?

Lexapro has been shown to be effective for generalized anxiety disorder (GAD) in multiple clinical studies by the FDA, though symptom improvement typically occurs gradually over several weeks rather than immediately. So, when it comes to answering how long it takes for Lexapro to work for anxiety, several factors come into play. Individual response time and dose strength can both affect how quickly Lexapro treatment starts working.

Given these variables, it's also crucial to understand that anxiety symptoms in women can differ from those in men. influencing how treatment effects might manifest and thereby guiding a personalized approach to anxiety management. That said, there's no difference in response to Lexapro between men and women as per the FDA.

• First dose – a couple of weeks: When starting Lexapro, be patient. Your body will adjust to the medication, and you might start to feel some ​​symptom relief within a couple of weeks. A small subset of people find that Lexapro works within a day or so, but that percentage is extremely small. Even if you're not experiencing the full benefits of the drug, continue taking your medication as prescribed.
• By 2 months: Most people notice a difference within 1 – 2 months. Mood and feeling motivated to engage in activities should be noticeably improved by this time.
• 2 months and beyond: Within 2 months, the majority of people start to see the full effects of Lexapro in their system. If you don't see a difference by this point, you should talk to your doctor about adjusting your dosage or trying another type of antidepressant medication.

This timeline aligns with the FDA clinical studies that evaluated Lexapro's effectiveness over 8-week treatment periods in people with depression and generalized anxiety disorder. How long before Lexapro works really just depends — everyone responds differently when taking medications. Each individual will react differently to each Lexapro dosage. Some people may feel better sooner, while others may not experience any symptom relief until later. Some may even experience certain side effects, like weight gain on Lexapro. As you wait for Lexapro to take effect, discovering additional strategies on how to deal with depression can be beneficial for a holistic approach to mental health care.

• Your mood is improving: One of the most common indications that Lexapro is working is improved mood.
• You have more energy or motivation: A shift in energy, especially in the mornings, is often one of the first signs that Lexapro is working. You might feel more motivated to get out of bed, complete tasks, or engage in small activities you'd been avoiding.
• You bounce back from stress more easily: Setbacks or challenges might still feel tough, but you're not as overwhelmed by them as you may have been in the past. You may find yourself recovering emotionally faster than before.
• You feel less anxious or on edge: Anxiety may not disappear right away, but you might notice a sense of calm creeping in. Racing thoughts slow down. You don't feel as tense or hypervigilant in daily situations.
• You're sleeping better: Many people notice improved sleep quality or an easier time falling and staying asleep. Better rest can also boost your daytime mood and functioning.

• You notice others commenting on changes: Sometimes others see changes before you do. Friends or loved ones may say you seem calmer, more present or a little more like yourself.

"Although the drug is a constant, we are different. Therefore, how a drug affects us vs. another person may be different. That is why it is so important to be in contact with your physician to inform them about how it is affecting you. Mental health medication is not one size fits all."

What to Do When Lexapro is Not Working

It can be hard to understand why a medication isn't working as expected. If you feel like Lexapro isn't helping, you can take a few steps to determine the cause and find an effective solution.

• Start by consulting your doctor: The first step should always be to talk with your doctor about any concerns or questions you have. They'll be able to assess whether the Lexapro dosage is correct or if another underlying issue, such as a medical condition, is causing symptoms.
• Evaluate your diet and exercise habits: Diet and exercise can significantly impact how well medications work to treat mental health issues such as depression or anxiety. It's also important to keep in mind how Lexapro interacts with certain substances. For example, be sure you don't drink alcohol with Lexapro, as this can cause adverse effects that counteract Lexapro's purpose.
• Consider alternative treatments: Alternative treatments, like cognitive behavioral therapy (CBT), mindfulness meditation techniques or yoga, might offer additional support for managing mental health conditions more effectively over time without relying solely on medication alone.
• Try other medications: If all else fails, it may be necessary to try other types of depression medication or anxiety medication. Consult with your healthcare provider about what other options they recommend.

*It's important to consult a medical professional about Lexapro alternatives before changing medications.

"I have had a client who began taking less and less of the medication with the goal of getting off entirely. I noticed some of the events in her life were causing more anxiety and she was less able to implement her coping skills. She began to see that this may not be the time to get off of the Lexapro that was helping her."
