Those taking a widely prescribed medication are being urged to “call 111” if they experience a particular symptom in the chest. This could indicate a “rare but serious” side effect of the drug.
Sertraline is an antidepressant commonly used to treat depression and a range of other mental health conditions. While no specific figures for the drug are available, it is known to be taken by a significant proportion of the more than eight million people in England currently on antidepressants.
The medication is believed to work by boosting levels of serotonin, a chemical in the brain responsible for regulating mood. When serotonin levels are balanced, the NHS explains, you feel calmer and happier.

It can be prescribed for depression, obsessive-compulsive disorder (OCD), panic disorder, post-traumatic stress disorder (PTSD), and social anxiety disorder. However, like all medications, it can trigger unwanted side effects.
The NHS states: “Like all medicines, sertraline can cause side effects, although not everyone gets them. Most side effects should ease after a couple of weeks as your body gets used to the medicine, but some can last longer.”
Among the “common side effects” of sertraline are headaches, feeling sick (nausea) and being sick (vomiting), and dizziness or drowsiness. The NHS advises that you should consult a pharmacist or doctor if any side effects are troublesome or persistent.
However, there are some more serious side effects to be aware of. “Sertraline can sometimes cause more serious side effects, although most of them are rare,” the NHS says.

One such side effect is serotonin syndrome. Symptoms of this condition include an unpleasant sensation in the chest and a rapid heartbeat.
Additional warning signs include sweating, shaking, muscle twitching, and feelings of confusion or agitation. In such circumstances, you should “call 111” for assistance.

Other potential serious side effects of sertraline are:
- An allergic reaction (anaphylaxis) – causing symptoms such as a swollen throat or tongue, a raised, itchy rash and difficulty breathing
- Feeling very low and having suicidal thoughts
The NHS advises that you should call NHS 111 if you are taking sertraline and believe you may be experiencing serious side effects, or if you are having thoughts about harming yourself.
