Escitalopram is a type of antidepressant known as an SSRI (selective serotonin reuptake inhibitor).
Escitalopram helps many people recover from depression, and it has fewer unwanted effects than older antidepressants.
Escitalopram is available on prescription. It comes as tablets and as liquid drops that you put in a drink.
- It usually takes 4 to 6 weeks for escitalopram to work.
- Side effects such as nausea and headache are common. They are usually mild and go away after a couple of weeks.
- Escitalopram can affect an unborn baby. Tell your doctor straight away if you’re trying to get pregnant or become pregnant while taking it.
- Escitalopram can cause withdrawal symptoms so don't stop taking it without talking to your doctor.
- Escitalopram is called by the brand name Cipralex.
Who can and can't take escitalopram
Escitalopram can be taken by adults over the age of 18.
Escitalopram isn't suitable for some people. Check with your doctor before starting to take escitalopram if you:
- have had an allergic reaction to escitalopram or any other medicines in the past
- have epilepsy – as escitalopram can increase your seizures
- have a heart problem - as escitalopram can speed up or change your heartbeat

- have liver or kidney problems – your doctor may need to change your dose
- have been told you have low sodium (salt) levels

- have ever taken any other medicines for depression – some rarely used antidepressants can interact with escitalopram to cause very high blood pressure even when they've been stopped for a few weeks
- are trying to become pregnant, are already pregnant or are breastfeeding – escitalopram is not usually recommended in pregnancy or while breastfeeding
- have an eye problem called glaucoma because escitalopram can increase the pressure in your eye
If you have diabetes, escitalopram can make it more difficult to keep your blood sugar stable. Monitor your blood sugar more often for the first few weeks of treatment with escitalopram and adjust your diabetes treatment if necessary.
How and when to take
Take escitalopram once a day. You can take it with or without food.
You can take escitalopram at any time of day, as long as you stick to the same time every day. If you have trouble sleeping, it's best to take it in the morning.
How much will I take?
Escitalopram tablets come in different strengths ranging from 5mg to 20mg.
The usual dose of escitalopram is 10mg a day in adults. However, you may start on a lower dose and increase to a maximum dose of 20mg a day. If you have liver problems, the maximum recommended dose is 10mg a day.
With liquid drops of escitalopram, 1 drop is equivalent to 1mg, 10 drops is 10mg, 20 drops is 20mg.
What if I forget to take it?
Do not take a double dose to make up for forgotten doses. If you do forget to take a dose, and you remember before you go to bed, take it straight away. Carry on as usual the next day. If you only remember during the night, or the next day, leave out the missed dose and carry on as usual.
If you forget doses often, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to help you remember to take your medicine.
What if I take too much?
Ask your doctor for advice straight away as overdose can lead to potentially serious symptoms such as:
- fast heart rate

How to cope with side effects
What to do about:
- feeling sleepy – cut down the amount of alcohol you drink
- dry mouth – chew sugar-free gum or sugar-free sweets
- being unable to sleep – take escitalopram first thing in the morning
Except for problems getting to sleep, you can reduce the chance of having a side effect that bothers you if you take escitalopram in the evening. That way you're asleep when the level of medicine in your body is highest.
Pregnancy and breastfeeding
Escitalopram is generally not recommended in pregnancy or while breastfeeding.
No medicines for depression are considered completely safe to take in pregnancy or while breastfeeding. Your doctor will want to prescribe escitalopram when the benefits of you taking the medicine outweigh the risks.
Escitalopram and similar antidepressants have been linked with a small risk of problems for the unborn baby if you take them in late pregnancy.
Escitalopram and breastfeeding
Escitalopram passes into breast milk and has been linked with side effects, including withdrawal symptoms, in breastfed babies.
Tell your doctor if you're trying to get pregnant, are already pregnant or if you're breastfeeding.
Cautions with other medicines
Some medicines and escitalopram can interfere with each other and increase the chances of you having side effects.
Tell your doctor if you're taking these medicines before you start escitalopram:
- any medicines that affect your heartbeat – as escitalopram can speed up or change your heartbeat
- any other medicines for depression – some rarely used antidepressants can interact with escitalopram to cause very high blood pressure even when they have been stopped for a few weeks
These are not all the medicines that can interfere with escitalopram. For a full list see the leaflet inside your medicine packet or check with your pharmacist.
Mixing escitalopram with herbal remedies and supplements
Don't take St John's wort, the herbal remedy for depression, while you are being treated with escitalopram as this will increase your risk of side effects.
Tell your doctor or pharmacist if you're taking any other medicines, including herbal remedies and supplements.
