What is citalopram?

Citalopram is a type of antidepressant known as a selective serotonin reuptake inhibitor (SSRI). Citalopram is used to treat depression, usually for people with moderate to severe depression, where psychological therapy and lifestyle changes have not been enough for the depression to go away.

For most people the effectiveness of antidepressants can be improved when they are used together with psychological therapies, like CBT (cognitive behavioural therapy), and lifestyle changes. Read more about depression.

We don't know for certain, but researchers think that SSRIs could work by increasing the activity of serotonin which is thought to improve mood, emotion and sleep. Read more about SSRIs.

Dose

In Aotearoa New Zealand citalopram is available as tablets (20 mg).

The dose of citalopram will be different for different people.
Your doctor will usually start you on a low dose and if needed, will increase your dose slowly. This allows your body to get used to the medicine and reduces the chance of side effects.
Always take your citalopram exactly as your doctor has told you. The pharmacy label on your medicine will tell you how much citalopram to take, how often to take it, and any special instructions.

How to take citalopram

Take citalopram once a day, in the morning OR the evening. Take your dose at the same time each day. 
You can take citalopram with or without food but if you think it is upsetting your stomach, try taking it with food.
Missed dose: If you forget to take your dose, take it as soon as you remember. But if it is nearly time for your next dose, just take it at the right time. Do not take double the dose.
Keep taking citalopram every day. It may take 4 to 6 weeks before you notice the full benefits of citalopram and you should start to feel better after 1 to 2 weeks. Some people notice side effects in the first few weeks before they start to feel better. Citalopram is usually needed for at least a few months. Your doctor will discuss with you how long to take it for; this depends on what you are taking it for, and how well it is working.
If you think citalopram isn't working for you. Don't stop taking it suddenly; talk to your doctor or nurse before stopping. It is usually best to stop taking citalopram very slowly to avoid side effects.

Things to consider while you are taking citalopram

Limit alcohol intake while you are taking citalopram. Alcohol can increase your chance of side effects such as drowsiness and reduced concentration.
Avoid driving and doing other tasks where you need to be alert until you know how this medicine affects you.
Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.
Citalopram can interact with some other medicines (including anticoagulants and anti-inflammatories such as ibuprofen), herbal supplements (eg, St John's Wort), and recreational drugs, so check with your doctor or pharmacist before starting citalopram and before starting any new products.
If you have diabetes, you may need to check your blood glucose more often because citalopram can affect the levels of glucose in your blood.

Possible side effects of citalopram

Like all medicines, citalopram can cause side effects, although not everyone gets them. Often side effects improve as your body gets used to the new medicine.
