NHS crucial message to everyone taking citalopram

People taking or starting citalopram may be advised to contact NHS 111 if they experience certain side effects. The NHS explains that it is an antidepressant used to treat depression and panic disorder, and is only available on prescription.

It explains: “Citalopram is 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.” While available with a prescription only, if you take too much citalopram, it warns that “an extra dose of citalopram can be dangerous.”

Call NHS 111

You should call 111 if “you’ve taken more than your prescribed dose of citalopram” as this can be dangerous. You should also call them if you’re taking citalopram and think you might be having serious side effects or you’re having thoughts about harming yourself.

It cautions: “If you’re told to go to A&E, do not drive. Ask someone to drive you or call 999 and ask for an ambulance. Bring the citalopram packet or leaflet inside it, any remaining medicine, and any other medicines you take.”

What are the side effects of citalopram?

As with all medicines, citalopram may cause side effects, though not everyone will experience them. Most side effects tend to improve within a couple of weeks as your body gets used to the medicine, although some may persist longer.

Common side effects of citalopram include:

• headaches
• feeling sick (nausea) and being sick (vomiting)
• sweating
• dry mouth
• diarrhoea or constipation
• problems sleeping
• a fast heartbeat (palpitations)
• sexual problems, such as low sex drive (loss of libido)

If you experience dizziness or drowsiness while taking citalopram, do not drive, cycle, or use machinery until these effects have fully gone.

Possible serious side effects of citalopram include:

• an allergic reaction (anaphylaxis) – causing symptoms such as a swollen throat or tongue, a raised, itchy rash and difficulty breathing
• serotonin syndrome – a rare but serious condition that causes a fast heartbeat, sweating, shaking, twitching muscles and feeling confused or agitated
• internal bleeding, which you may notice if you have bruises, or blood in your pee, poo or vomit
• a rare, life-threatening condition that causes a fast, irregular heartbeat, light-headedness and fainting (torsades de pointes)
• feeling very low and having suicidal thoughts

These are not all the side effects of citalopram. For a full list, see the leaflet that comes with your medicine or search for your medicine on the electronic medicines compendium website. You can report any side effects you get on the Yellow Card website.
