Escitalopram is used to treat a number of mental health conditions including depression and anxiety. Find out how to take it safely and possible side effects.

What is escitalopram?

Escitalopram is a type of antidepressant known as a selective serotonin reuptake inhibitor (SSRI). SSRIs are the most frequently prescribed antidepressants.

Escitalopram is used to treat a number of mental health conditions including depression, obsessive-compulsive disorder, and anxiety.

It is believed that SSRIs work by increasing the levels of a chemical called serotonin. This helps enhance mood. You should notice that you sleep better and feel more relaxed.

In Aotearoa New Zealand escitalopram is available as tablets (10 mg, 20 mg).

  • The usual dose of escitalopram is 10 mg once a day.
  • Depending on your response, and if you need to, your doctor may increase your dose to 20 mg once a day.
  • Always take your escitalopram exactly as your doctor has told you. The pharmacy label on your medicine will tell you how much escitalopram to take, how often to take it and any special instructions. 

How to take escitalopram

  • Take escitalopram once a day, at the same time each day, either in the morning OR in the evening. 
  • Food: You can take escitalopram with or without food but if you think it is upsetting your stomach, try taking it with food. Take your dose with a full glass of water.
  • Missed dose: If you forget to take your tablet, take it as soon as you remember. But, if it is nearly time for your next tablet, just take the next tablet at the right time. Do not take double the amount of tablets.
  • Keep taking escitalopram every day. It may take 4 to 6 weeks before you notice the full benefits of escitalopram and you should start to feel better after 1 to 2 weeks. Some people feel worse in the first few weeks before they feel better. Escitalopram is often needed for at least a few months and your doctor will tell you how long to take it for.
  • If you think escitalopram is not working for you. Do not stop taking it suddenly; speak to your doctor or nurse before stopping. It is usually best to stop taking escitalopram very slowly to avoid side effects.

Read more about what to expect when starting SSRIs – see SSRIs and frequently asked questions (FAQs) about SSRIs.


Diabetes: if you have diabetes, you may need to check your blood glucose more often because escitalopram can affect the levels of glucose in your blood.

Interactions with other medicines and herbal supplements: Escitalopram  can interact with some medications (including anticoagulants and NSAIDs), herbal supplements, and recreational drugs, so check with your doctor or pharmacist before starting escitalopram and before starting any new products.
