Escitalopram
NHS information about the medicine escitalopram, including what it's used for, who can take it, how to take it and side effects.
What escitalopram is for
Escitalopram can be used to treat mental health conditions such as:
- depression
- obsessive compulsive disorder (OCD)
- generalised anxiety disorder
- social anxiety disorder
- panic disorder
It's a type of antidepressant called a selective serotonin reuptake inhibitor (SSRI).
It's thought to work by increasing the level of serotonin (a chemical in the brain linked to mood). When serotonin levels are normal, this may reduce stress levels and negative thoughts.
How to take escitalopram
Escitalopram comes as tablets you swallow, tablets you let dissolve in your mouth (orodispersible tablets) or liquid drops.
You usually take escitalopram once a day. How much you need to take depends on why you're taking it.
Your doctor may prescribe a low dose to start with and increase it after a few weeks. This reduces the chances of side effects.
It can take several weeks until your symptoms start to improve.
When taking escitalopram:
- swallow tablets whole, with a drink of water
- put orodispersible tablets on your tongue and let them dissolve, then swallow with a drink of water
- for liquid drops, turn the bottle upside down and count the correct number of drops into a glass of water (or orange or apple juice), stir and then drink
- you can take escitalopram with or without food
You may need to take escitalopram for a long time. For example, if you're taking it for depression, you'll probably need to keep taking it for 6 months or more.
Always check the packet or leaflet that comes with your medicine. Ask a pharmacist or doctor for advice if you're not sure how to take it or have any problems taking it.
If you miss a dose of escitalopram
If you forget to take a dose of citalopram, take it as soon as you remember, unless it's nearly time for your next dose.
If it's nearly time for your next dose, skip the dose you missed and take your next dose the next day as usual.
Do not take 2 doses to make up for a missed dose.
If you take too much escitalopram
Taking an extra dose of escitalopram can be dangerous.
Side effects of escitalopram
Like all medicines, escitalopram can cause side effects, although not everyone gets them.
Most side effects should ease after a couple of weeks as your body gets used to the medicine, but some can last longer.

Breastfeeding and escitalopram
Tell your doctor if you're breastfeeding.
Escitalopram is sometimes used while breastfeeding, but it's best to check because the medicine can pass into your breast milk.
Your doctor may suggest you continue taking escitalopram if the benefits to you outweigh any possible risks to your baby, but they may suggest switching to a different antidepressant.
It's possible for breastfed babies to get side effects from escitalopram, so speak to a healthcare professional or call NHS 111 if you have any concerns about your baby.
Pregnancy and escitalopram
Tell your doctor if you're pregnant or you get pregnant while taking escitalopram.
Escitalopram can be used during pregnancy if needed. Your doctor will talk to you about the risks and benefits of taking it while you're pregnant.
If you need to take escitalopram while you're pregnant, your doctor will prescribe the lowest possible effective dose.
You'll also usually be advised to give birth in hospital so you and your baby can be closely monitored after you've given birth.

There are some medicines, remedies and supplements that may not mix well with escitalopram.
These include:
