Lexapro (escitalopram) is an antidepressant medication commonly prescribed for anxiety and depression. It can be taken with or without food, once a day, either in the morning or at night. While Lexapro can help ease sleep disturbances, it may also cause insomnia or daytime sleepiness in some people, especially during the first few weeks of treatment. If you are experiencing insomnia while taking Lexapro, it may be preferable to take it in the morning or earlier in the day to reduce the concentration of the medication in the blood by nighttime. Lifestyle interventions, such as sleeping in a cool, dark room and minimizing noise, and avoiding alcohol, may also help with insomnia. It is important to consult with a healthcare professional before starting, changing, or stopping Lexapro or any other medication.

What You'll Learn

Lexapro and insomnia
Lexapro, also known as escitalopram, is a selective serotonin reuptake inhibitor (SSRI) that is used to treat depression and anxiety. While it is typically taken once a day, there is no specific time that it needs to be taken. However, for those experiencing insomnia, it is recommended to take it in the morning. This is because the medication reaches its peak blood concentration about five hours after taking it, and taking it earlier in the day gives the body time to break it down, reducing the likelihood of it interfering with sleep at night.
Insomnia is a common side effect of Lexapro, with some individuals experiencing difficulty falling asleep, staying asleep, or waking up too early. It is important to note that insomnia is also a common symptom of depression, so it may be challenging to determine whether it is caused by the medication or the underlying condition. In some cases, treating depression with Lexapro may also help treat insomnia and other symptoms.
If you are experiencing insomnia while taking Lexapro, there are several things you can try. Firstly, consider taking the medication in the morning, as mentioned earlier. Secondly, make sure you are practising good sleep hygiene, which includes sleeping in a cool, dark, and quiet room, maintaining a consistent sleep schedule, avoiding daytime napping, reducing caffeine intake, and minimising noise. Additionally, avoiding alcohol and caffeine before bedtime may also help improve sleep quality.
If these self-help measures do not improve your insomnia, it is important to consult your healthcare provider. They may recommend adjusting the dosage or trying a different medication. It is crucial not to stop taking Lexapro or change the dosage without first consulting a medical professional.

Daytime sleepiness
If you are experiencing daytime sleepiness while taking Lexapro, there are a few things you can try. Firstly, consider switching to a morning dosing schedule. Taking Lexapro in the morning can help regulate mood and energy levels throughout the day and may reduce the sedative effects of the medication during the daytime. To switch to a morning dosing schedule, simply skip your nighttime dose and take your next dose in the morning. It is important to maintain consistency in the timing of your medication to ensure steady medication levels.
Additionally, you can try incorporating lifestyle interventions to help manage daytime sleepiness. This includes getting regular exercise, but not within 4-5 hours of bedtime, as this can interfere with sleep. Reducing caffeine intake, especially in the afternoon and evening, can also help, as caffeine has stimulant effects that can disrupt sleep. Maintaining a consistent sleep-wake schedule and creating a comfortable sleep environment with minimal distractions can also promote better sleep quality.
If you are experiencing excessive sleepiness that negatively impacts your daily life, it is important to notify your healthcare provider. They can help you decide whether to continue with Lexapro or try a different medication. Your healthcare provider may also recommend adjusting your dose or trying a different medication to treat insomnia.

Lifestyle interventions
While there is no scientific consensus on the best time to take Lexapro to avoid insomnia, lifestyle interventions can help those experiencing sleep issues while taking the medication.
Firstly, it is important to note that Lexapro interacts with several medications, most notably monoamine oxidase inhibitors (MAOIs) and other antidepressants that increase serotonin levels. Therefore, it is not recommended to take these medications while also taking Lexapro, even if the timings are staggered throughout the day. If you are taking medication for insomnia, this may dictate when you take Lexapro to get the best quality sleep.
If you are experiencing insomnia while taking Lexapro, you may want to consider taking it earlier in the day. The medication reaches peak blood concentration around 5 hours after taking it, and the concentration steadily declines after that. Taking it in the morning may help to reduce the concentration of the medication in the blood by nighttime, which could reduce insomnia.
Additionally, there are several lifestyle changes you can make to improve your sleep while taking Lexapro:
- Sleep in a cool, dark room. This includes turning off phones and televisions and blocking ambient light.
- Minimise noise by wearing earplugs or using a white noise machine.
- If you experience daytime drowsiness, skip naps during the day and try to exercise.
- Avoid drinking alcohol, as this may make you feel sleepier.
- Avoid consuming cannabis, as this can make drowsiness worse, especially if you have just started taking Lexapro.

Side effects
Lexapro (escitalopram) is an antidepressant that can cause a range of side effects, with insomnia being one of the most common. Insomnia induced by Lexapro can manifest as difficulty falling asleep, staying asleep, or waking up too early, which can subsequently lead to reduced focus, fatigue, and irritability. To minimise insomnia, it is recommended to take Lexapro in the morning or afternoon, maintain good sleep hygiene, and avoid caffeine and alcohol before bedtime. If insomnia persists or significantly impacts your quality of life, consult your healthcare provider.
Other side effects of Lexapro may include drowsiness, decreased appetite, increased sweating, nausea, diarrhoea, and sexual side effects. These side effects typically occur during the first week of taking Lexapro and are usually mild at lower doses. However, severe side effects such as serotonin syndrome and increased suicidal thoughts can occur in rare cases. It is important to seek immediate medical care if you experience any severe side effects.
Serotonin syndrome is a rare but potentially life-threatening condition that arises from excessive serotonin levels in the body. It can occur within 24 hours of increasing your Lexapro dose or when taking another serotonin-boosting medication. Signs of serotonin syndrome include high temperature, agitation, confusion, trembling, twitching, and in severe cases, sudden confusion, drowsiness, or dizziness. If you experience any of these symptoms, seek medical attention immediately.
Additionally, Lexapro may worsen depression and increase suicidal thoughts, especially in children, teenagers, and young adults. If you or your loved ones experience any changes in mood or thoughts of self-harm, it is crucial to contact your healthcare provider right away.
It is important to remember that individual responses to Lexapro may vary, and side effects can depend on factors such as dosage and unique physiological characteristics. Always consult your healthcare provider before starting, adjusting, or discontinuing any medication, including Lexapro.

Interactions with other medications
Lexapro (escitalopram) is an antidepressant that belongs to a group of medicines called selective serotonin reuptake inhibitors (SSRIs). It is typically taken once a day and can be taken either in the morning or at night. However, for those experiencing insomnia, it may be beneficial to take it earlier in the day to reduce the concentration of the medication in the blood by nighttime.
When considering the interaction of Lexapro with other medications, it is important to note that it may alter the blood levels of certain drugs. There are 710 known drug interactions with Lexapro, 267 of which are major interactions. It is crucial to consult a healthcare provider and disclose all medications currently being taken or that have been taken recently. This includes prescription medications, over-the-counter drugs, vitamins, minerals, herbal products, and supplements.
Lexapro interacts with monoamine oxidase inhibitors (MAOIs), certain antidepressants, St. John's wort, blood thinners, nonsteroidal anti-inflammatory drugs (NSAIDs), and alcohol. Combining Lexapro with MAOIs, such as rasagiline (Azilect) or selegiline (Zelapar, Emsam), can lead to a condition called serotonin syndrome, which can cause mild symptoms like sweating, rapid heart rate, and tremors, as well as more severe symptoms such as rigid muscles, confusion, and high fever. St. John's wort, an herbal supplement, can also increase serotonin levels, and taking it with Lexapro raises the risk of serotonin syndrome.
Lexapro should not be consumed with alcohol as this combination can increase sleepiness and affect alertness and concentration. It is also important to note that Lexapro interacts with other antidepressants and may impact serotonin levels in the brain. Additionally, Lexapro interacts with blood thinners and NSAIDs, increasing the risk of severe bleeding.
It is important to consult a healthcare provider before taking Lexapro to ensure safe and effective use, especially when considering interactions with other medications.
