Why this happens
Sertraline (an SSRI antidepressant) can affect how platelets in your blood work to form clots. Naproxen (an NSAID painkiller) can irritate the lining of the stomach and also thins the blood slightly. When used together, these two effects combine, making a bleed in the digestive tract more likely.

Additionally, if you take magnesium as an antacid or supplement at the same time as esomeprazole, it might slightly interfere with how well the medicine is absorbed.
