What is Lexapro?

Lexapro¹ is a brand of medication used to treat depression. It is a drug known as escitalopram, classified as a selective serotonin reuptake inhibitor (SSRI). You can only get Lexapro with a prescription from a doctor. It is used to treat:

  • Generalized anxiety disorder (GAD)

  • Major depressive disorders

  • Depression

  • Dementia with depressive features

  • Depressive psychosis

To ensure optimal results while taking Lexapro, take a dose at the same time each day. Follow your doctor’s recommendations on proper dosage. Typically, the dosage will vary based on your age and your needs. The lowest effective dose is always used. 

  • Adolescents: 10 mg once daily for three weeks, and may increase to 20 mg daily

  • Adults: 10 mg daily, and may increase to 20 mg daily after the first week

You should avoid taking yourself off Lexapro suddenly. If you do, you could experience withdrawal symptoms. These are caused by the body’s inability to adjust to the sudden change in serotonin levels.

How often are antidepressants used in the U.S.?

It’s estimated that over 13.2%² of Americans take antidepressants regularly to improve their mood and take control of their mental health. Of those antidepressants, SSRIs are among the most popular, with name brands like:

  • Lexapro (Escitalopram)

  • Prozac (Fluoxetine)

  • Celexa (Citalopram)

  • Paxil (Paroxetine)

  • Zoloft (Sertraline)

Each of these prescription medications can be beneficial to someone who has depressive episodes or anxiety. However, sometimes they may also cause unwanted side effects. 

The good news is that most side effects are short-term and many others can be relieved if you make good choices while taking them.  

Can Lexapro cause insomnia?

When taking Lexapro, there are a variety of side effects you may experience. Unfortunately, two are very common: fatigue and insomnia.

When you initially start taking Lexapro, it can throw things a little off balance, similar to how stopping Lexapro too fast can mess with the level of serotonin in your brain.

One thing you can do to help yourself overcome Lexapro insomnia is to learn how to manage and deal with it. One option is to consider taking it in the morning so that you are awake during the day and ready for bed when it is time to rest.

How to manage and deal with insomnia when taking Lexapro

If you are dealing with depression, anxiety, and other issues, you may already be familiar with sleep troubles. Beyond taking your medication in the morning, there are several things you may want to try if you want to get a good night’s sleep. Often, these ideas are the same whether you take Lexapro or not.

Here are the most common suggestions for avoiding insomnia when taking Lexapro:

Avoid alcohol or other stimulants

Although alcohol can make you sleep, it can also negatively affect your sleep. You should avoid consuming alcohol in the first place when taking Lexapro. Otherwise, you may end up feeling nauseated, which can make it even more challenging to rest.

Exercise more often

When you exercise, you may reduce anxiety and depression symptoms. It can help your body’s internal clock reset so that you can get back to a regular sleep routine.

Limit your caffeine intake

Caffeine can cause your body and mind to stay more alert,⁵ depriving you of sleep. If you are experiencing insomnia as a side effect, you may want to stop drinking it 6 hours before bed or longer if you still don’t feel that you get the sleep your body requires.

Turn off devices before bedtime

People often use their devices within an hour of going to bed. The screen can become a distraction,⁶ especially if you have difficulty setting limits for yourself on when to turn it off.

Create an effective sleep space

Your bedroom should be a place where you can relax. This may mean designing a bedroom that is made for sleeping. According to the Sleep Foundation,⁷ some things you may try are:

  • Upgrading your mattress and bedding

  • Reducing clutter

  • Limiting bold colors

  • Turning off the lights

  • Cooling your room

  • Using white noise

You may also consider using meditation and aromatherapies to help you fall asleep more soundly. Some popular essential oil choices⁸ are lavender, chamomile, and clary sage oils.
