Why this happens
Naproxen is an NSAID that thins the blood slightly by affecting platelets and can irritate the stomach lining. Quinine can also lower platelet counts in some people, leading to an additive effect on bleeding risk.

Patient picks for Drug interactions

Treatment and medication
Can I take Abilify and Fluoxetine together?
Taking fluoxetine with Abilify (aripiprazole) can significantly increase the amount of Abilify in your bloodstream. This makes you much more likely to experience side effects such as extreme sleepiness, restlessness (feeling like you cannot sit still), uncontrollable body movements (tremors or twitching), and dizziness. There is also a small but serious risk of a heart rhythm problem called QT prolongation.

Treatment and medication
Can I take Levothyroxine and Ramipril together?
There is no direct interaction between levothyroxine and ramipril. However, if your thyroid levels are not well-controlled, it can affect how well your blood pressure medication works.
