Antidepressant Overdose Kills Grandmother
4 Mar
Summary
- A grandmother died after taking a fatal level of sertraline.
- Toxicology revealed sertraline levels at a potentially fatal concentration.
- Coroner ruled the death an accidental, unintended sertraline overdose.

A grandmother from Gravesend, Kent, tragically died on November 11 after an accidental overdose of sertraline, a commonly prescribed antidepressant. Grace Uludag, 55, had reported feeling dizzy and breathless the day before her death and was advised to call an ambulance. She passed away at home the following day after falling and suffering a cardiac arrest.
Toxicology tests conducted during the inquest revealed sertraline levels in her blood at 1.94 milligrams per litre, a concentration known to be a contributing factor in death and exceeding the 1.5 mg/L threshold. The assistant coroner concluded that Grace's death resulted from an overdose, emphasizing there was no evidence of intentional self-harm.
This incident follows an NHS warning in February regarding a potentially lethal side effect of sertraline called serotonin syndrome. Major studies have indicated that certain antidepressants can cause fluctuations in weight, heart rate, and cholesterol within the first eight weeks of treatment. Researchers recommend updating treatment guidelines while stressing individualized antidepressant selection.
Grace's family stated she lived for her family and grandchildren and had no suicidal tendencies. They expressed confusion regarding the overdose, with her daughter questioning the dosage. The coroner described the accidental overdose as an "unexpected and unintended consequence."
