Does Lexapro cause night sweats? Escitalopram can trigger them, but for many people they ease within weeks. Learn the timeline and comfort tips.
Waking up sweaty after starting escitalopram (Lexapro) can feel alarming, especially if the medication is helping your mood and you do not want to give it up. Many people wonder the same thing right away: is this temporary, or is it going to keep happening every night?
The short answer is yes, escitalopram can cause increased sweating, including night sweats, and for many people it does get better after the first couple of weeks. The National Health Service (NHS) says many escitalopram side effects ease as the body gets used to the medicine, though some can last longer (NHS).
Escitalopram is a selective serotonin reuptake inhibitor (SSRI). SSRIs change serotonin signaling, which can help with anxiety and depression, but serotonin also affects body temperature regulation and sweating. That is one reason some people notice damp sheets, sweaty pajamas, or sudden overheating at night after they start the medication or raise the dose.
The official prescribing information for Lexapro lists increased sweating among its more common adverse reactions. That does not mean everyone gets it, and it does not mean sweating will stay the whole time you take the medication. It does mean your experience is real and recognized.
Night sweats on escitalopram can show up in a few different ways. Some people feel a brief hot flash and then cool off. Others sleep hot the whole night and wake up clammy. A smaller group gets drenching sweats that disrupt sleep and force a clothing or sheet change.
For many people, yes. The most common pattern is that sweating starts in the first days or weeks, then settles down as the body adjusts. The NHS notes that many side effects should ease after a couple of weeks, though some symptoms hang on longer for certain people (NHS).
That said, there is no exact clock that fits everyone. Dose, body chemistry, room temperature, other medications, and hormone changes all matter. If the sweating is mild and you have only recently started escitalopram, a short watch-and-wait period is often reasonable if your prescriber agrees.
Here is a general guide to what many people notice, and what to do at each stage:
A common scenario looks like this: someone starts escitalopram for anxiety, sleeps poorly for the first week, then notices their chest, neck, or legs getting hot under the covers around 3 A.M. By week two, the sweating is less intense. By week three or four, it is still there once in a while, but no longer soaking the bed.
That does not happen for everybody.
If your night sweats are still strong after a few weeks, or they began only after a dosage change, your prescriber may want to review the dose, timing, or whether another medication is adding to the problem.
Night sweats are often just a medication side effect. Still, they should not be brushed off if they are severe, sudden, or paired with other symptoms. MedlinePlus warns that sweating can be part of a more serious reaction when it occurs with agitation, confusion, hallucinations, a fast or irregular heartbeat, muscle stiffness, twitching, or loss of coordination (MedlinePlus).
You should also think beyond the medication if the sweating started before escitalopram, keeps getting worse, or comes with fever, weight loss, swollen lymph nodes, chest pain, or breathing trouble.
Call a clinician promptly if you have any of these red flags:
You may not be able to shut off the side effect instantly, but you can often make the night much easier. Start with the basics: lower the bedroom temperature, choose lightweight sleepwear, keep a spare shirt nearby, and skip alcohol close to bedtime if you notice it makes you warmer.
Sleep experts often recommend a cool bedroom for better sleep (Sleep Foundation). Many bFan customers tell us that with targeted bed airflow they can set the thermostat a little higher and still sleep comfortably, because the air is moving right where heat gets trapped under the covers.
These small changes can help right away:
It also helps to pay attention to patterns rather than guessing. Keep a short log for a week and note your dose, the time you take it, alcohol or spicy food, room temperature, menstrual cycle changes if relevant, and how bad the sweating was. That gives your prescriber something useful to work with.
Room cooling is helpful, but many people with medication-related night sweats are dealing with heat trapped between their body, mattress, and bedding. That is why someone can feel overheated even when the bedroom itself is not that warm.
A targeted option like the bFan is built for that exact problem. It does not chill the air. Like any bed fan, it uses the cooler air already in the room and moves it under the covers so trapped body heat can escape, and direct airflow helps stop sweat before it starts. For people who wake sweaty from the waist down, behind the knees, or along the chest and back, that direct airflow can feel very different from a ceiling fan.
Tightly woven, higher thread count sheets usually work best because they help the airflow spread across the bed and move trapped heat out from around your body instead of letting the air spill out too quickly. That matters more than people expect.
Many hot sleepers do better when they stop piling up “cooling” products and focus on airflow plus lighter layers. Moving air where heat builds up often matters more than adding heavier bedding marketed as “cooling.”
If your sweating is tied to escitalopram, that can mean fewer wakeups even before the side effect fully settles down.
A simple setup often works better than an expensive one:
Sometimes. Some people feel warmer at night if they take escitalopram in the evening, while others notice no difference at all. If the sweating seems to peak a few hours after your dose, ask your prescriber whether a morning schedule makes sense for you.
Do not change timing, dose, or stop the medication on your own if you are not sure how to do it safely. MedlinePlus notes that stopping escitalopram suddenly can cause withdrawal symptoms, and sweating is one of them (MedlinePlus).
A short, direct conversation usually goes better than a vague “I am not sleeping well.” Tell them when the sweating started, how often it happens, whether it began after a dose increase, and whether it is ruining your sleep or causing dehydration.

If escitalopram night sweats are hitting you right now, try two things at once: talk with your prescriber about the timeline, and set up your bed so trapped heat can escape tonight. If you want targeted airflow right where the sweating happens, take a look at the bFan and see whether under-sheet airflow could make sleep easier while your body adjusts.
It can. Increased sweating is listed among the more common side effects of escitalopram, and some people notice it mostly at night. Not everyone gets it.
For many people they ease within the first couple of weeks as the body adjusts, though some people notice them longer. A dose increase can bring them back for a while.
No, not on your own. Stopping escitalopram suddenly can cause withdrawal symptoms, including sweating. Talk with your prescriber about the dose, timing, or other options.
Get medical help quickly if sweating comes with agitation, confusion, a fast heartbeat, muscle stiffness, twitching, fever, or trouble breathing. These can point to a more serious problem.
A bed fan like the bFan does not treat the side effect, but it can help you stay comfortable. It moves room air under your sheets, and direct airflow helps stop sweat before it starts.
Tightly woven, higher thread count sheets usually work best, because they guide the airflow across the bed instead of letting it escape too quickly.
The bFan sits at the foot of your bed and sends a quiet stream of air under your sheets. Direct airflow helps stop sweat before it starts, and one bFan costs less than half the price of one BedJet, making it the less expensive alternative. Shop the bFan at bedfans-usa.com
