Why this happens
Amitriptyline belongs to a group of medicines that can affect how your blood platelets work. Aspirin is a blood-thinner that also stops platelets from sticking together. When used together, their combined effect makes it harder for your blood to clot, increasing the risk of internal bleeding.
What you should do
Back to contentsUse this combination with caution. If you need to take them together, watch for signs of bleeding such as dark, tarry stools, coughing up blood, or severe stomach pain. If you notice these symptoms, contact your doctor immediately. Your doctor may suggest a different painkiller or a medicine to protect your stomach.
