Why this happens
Aspirin thins the blood and can irritate the stomach lining, while quetiapine can sometimes interfere with how platelets (the cells that help blood clot) work. Additionally, both medications can cause a drop in blood pressure when standing, which may lead to dizziness.
What you should do
Back to contentsYou should use this combination with caution. Watch for signs of unusual bleeding, such as easy bruising, dark or 'tarry' stools, or coughing up blood. To avoid dizziness, try to stand up slowly from a sitting or lying position. If you have a history of stomach ulcers, speak to your doctor before taking aspirin.
