Pregnancy and breastfeeding
Do not take escitalopram if you are pregnant or breastfeeding, unless you have talked to your GP about the risks involved.
Escitalopram can affect an unborn baby and cause side effects for babies.
You should also talk to a GP or pharmacist before taking escitalopram if you're trying for a baby or think you might be pregnant.
Contraception and fertility
Escitalopram does not affect contraceptive pills or the morning after pill. It will not affect a woman's fertility.
Sperm quality in men might be reduced temporarily while you are taking escitalopram, but there is not much evidence to support this. Talk to your GP if you have concerns.
Diabetes and escitalopram
Monitor your blood sugar more often for the first few weeks of treatment if you have diabetes.
Escitalopram can make it more difficult to keep your blood sugar stable.
Your GP may adjust your diabetes treatment if necessary.
When you start taking escitalopram
Concentrating may be more difficult while you're taking escitalopram.
You should stop driving and cycling until you know how this medicine makes you feel. Do not operate machinery while taking escitalopram.
How and when to take escitalopram
Always take your medicine exactly as your GP tells you to.
You'll usually take escitalopram once a day. Try to stick to the same time every day.
You can reduce the chance of bad side effects if you take escitalopram in the evening. That way you're asleep when the level of medicine in your body is highest.
If you have trouble sleeping, take it in the morning instead of the evening.
You can take escitalopram with or without food.
Dosage of escitalopram
Usually you will be prescribed a daily dose of between 5mg to 10mg of escitalopram.
Your GP might start you on a lower dose and then increase to a maximum dose of 20mg a day.
Lower doses for liver problems
Your GP will not prescribe you more than 10 mg escitalopram if you have liver problems.
How long it takes to work
Do not stop taking escitalopram after a week or 2 because you feel it is not helping.
Usually it takes between 4 to 6 weeks to feel the full effect.
You might feel worse during the first few weeks of treatment before you begin to feel better. If you feel worse, talk to your GP.
Talk to your GP if you do not feel any better after 6 weeks.
How long you will need to take escitalopram
Once you feel better you'll probably continue to take escitalopram for several more months.
This is to prevent the symptoms returning.
Your GP can talk to you about the pros and cons of taking escitalopram for longer than a few months.
Any decision about continuing on escitalopram will depend on your situation, including:
- if you have a one-off problem or one that keeps coming back
- how well your body responds to escitalopram
Escitalopram is safe to take for a long time, even years.
Stopping taking escitalopram
Do not stop taking escitalopram suddenly unless your GP tells you to. You can get side effects when you stop or withdrawal symptoms.
Your GP might recommend reducing your dose of escitalopram gradually over several weeks. This can reduce your chance of unpleasant withdrawal symptoms.
If you forget to take it
Never take 2 doses 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.
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.

Side effects such as feeling sick and headaches are common. They are usually mild and go away after a couple of weeks.
