Why this happens
Apixaban is an anticoagulant that prevents blood clots by blocking a specific protein (Factor Xa). Omega-3 fatty acids have a mild 'antiplatelet' effect, meaning they make the small cells in your blood (platelets) less sticky. When used together, their combined effects can make it harder for your blood to clot if you are injured.
What you should do
Back to contentsYou should inform your doctor or pharmacist if you plan to take omega-3 supplements with apixaban. Watch for signs of unusual bleeding, such as frequent nosebleeds, bleeding gums when brushing teeth, or large bruises that appear for no reason.

Can I take Sertraline and Fluoxetine together?
Taking sertraline and fluoxetine together significantly increases the risk of a rare but serious condition called serotonin syndrome. This happens because both medicines work by increasing the level of a chemical called serotonin in your brain. If levels get too high, it can cause symptoms like shivering, diarrhoea, confusion, severe muscle tightness, fever, and even seizures. Additionally, fluoxetine can slow down how your body breaks down sertraline, leading to a build-up of the drug in your system and increasing the risk of side effects.

Taking aspirin and furosemide together can make the furosemide (water tablet) less effective at removing excess fluid from your body. Additionally, at high doses of aspirin, there is an increased risk of kidney problems and a build-up of aspirin in your blood, which can lead to side effects like ringing in the ears (tinnitus).
