Can I take 150 and Warfarin together?

Why this happens

Both medicines work to prevent blood clots but in different ways. Warfarin interferes with clotting factors in the blood, while aspirin stops platelets (blood cells) from sticking together. When used together, they 'double up' the blood-thinning effect. Additionally, aspirin can irritate the lining of the stomach, making it more likely to bleed, especially when warfarin is also present.

You should only take this combination if it has been specifically prescribed by a specialist (such as a cardiologist). Do not take 'over-the-counter' aspirin if you are on warfarin. If you are prescribed both, you must attend all blood test appointments (INR tests) and watch closely for signs of bleeding, such as unexplained bruising, blood in your urine or stools (which may look black and tarry), or nosebleeds that do not stop. Seek urgent medical help if you have a serious fall or hit your head.
