Lexapro Insomnia: What You Need to Know

What Is the Link Between Lexapro & Insomnia?

Insomnia is a common side effect in Lexapro, occurring in 9-14% of people vs 4-6% in placebo groups.² When taking an SSRI, you may regain your energy as your symptoms improve, which may result in insomnia. Other factors that could impact your sleep may include that you are getting more exercise, which can keep you awake at night if done too late in the day.

However, extreme tiredness is another common side effect of Lexapro (5-8% vs 2% in placebo groups).² Insomnia is a common symptom of anxiety and depression, so Lexapro may help this symptom improve. Also, Lexapro may cause tiredness because serotonin can influence the action of melatonin, a naturally-occurring hormone that helps us fall asleep.⁴

The Role of Serotonin in Insomnia

Serotonin helps improve your mood, which can increase your ability to function or enhance your quality of sleep. However, serotonin may induce wakefulness.⁴

Best Time to Take Lexapro to Avoid Insomnia

It is best to take Lexapro in the morning to prevent it from keeping you up at night. If you find that Lexapro instead can help you sleep or causes drowsiness, try taking it in the evening or at bedtime. Factors that may contribute to the timing of your medication include when you take other medications or the amount of time you’ve been taking Lexapro.

8 Tips for Managing Insomnia From Lexapro

Changing some of your lifestyle and sleep habits can help improve insomnia associated with taking Lexapro. You can start by avoiding drinking too much alcohol or drinking late in the day. In addition, your doctor may consider switching your antidepressant to one that is less likely to cause insomnia. Also, having a healthy sleep routine, diet, and getting enough exercise can contribute to a better night’s sleep.

Avoid Drinking Alcohol

The combination of alcohol and sleep problems has been shown in studies.⁵ While it may help you fall asleep quicker, it decreases your quality of sleep. You may also sleep less while having more sleep disturbances because alcohol affects sleep stages.

Consider Switching Antidepressants

If you can’t sleep from your Lexapro, your doctor may switch antidepressants to one less likely to cause insomnia. Other SSRIs also commonly cause insomnia, but since medications work differently for everyone, other antidepressants may be less likely to cause insomnia. Your doctor may also try decreasing your dose to maintain some benefits while preventing side effects.

Avoid Stimulants Such as Caffeine

Caffeine can make it harder for you to sleep if you drink too much, too late in the day, or combine it with other substances, including Lexapro. Stimulants can also increase the amount of time it takes for your body to adjust to Lexapro and can prolong insomnia. Try to stick to 1-2 cups per day at most in the morning or early afternoon.

Avoid Napping for Too Long or Too Late

Naps can be very beneficial for mental health and recharging. However, research shows they should be limited to 30 minutes and taken before 3 pm to help improve work efficiency and prevent insomnia.⁶ The benefits of naps have been shown to last about 2 hours.

Maintain Proper Sleep Hygiene

When preparing to sleep, there are a few guidelines you should follow to ensure you get optimal sleep. Have a dark and quiet place where you can rest. Also, it is best to keep your room a little cooler than normal. Not eating a large meal before bed can help as well.

Have a Sleep Routine

Going to sleep and waking up at the same time every day can be very helpful for teaching your mind when it is time to sleep. You can also add to this routine by doing relaxing things each night, such as taking a bath, lighting a candle, or reading a book. Avoiding screen time before bed can also help prevent insomnia.

Get Enough Exercise

Exercise has been shown to have many mental health benefits, including aiding in sleep onset and quality. You should aim to do 30 minutes of strenuous exercise most days of the week. Strenuous exercises include jogging, swimming, cycling, or weight training.

Eat a Healthy Diet

A healthy diet is another way to maintain good mental health and sleep quality. The nutrients you get from food provide you with fuel to maintain energy. They keep your body functioning properly throughout the day to prevent the need for naps. Staying hydrated can also keep you going during the day as well.

Will the Insomnia Go Away?

Insomnia from taking Lexapro may last for the first 1-2 weeks and then go away. However, each person will have a unique experience when taking the medication. Determining other potential causes of insomnia may be necessary. Side effects from other medications you are taking may also contribute to insomnia.

How Long Does Insomnia Last With Lexapro?
