Which medication is commonly associated with the risk of increased bleeding?

Aspirin is commonly associated with the risk of increased bleeding due to its mechanism of action as a nonsteroidal anti-inflammatory drug (NSAID) that irreversibly inhibits the enzyme cyclooxygenase (COX). This inhibition leads to a decrease in the production of thromboxane A2, which is important for platelet aggregation. As a result, aspirin reduces the ability of platelets to clump together, thereby increasing the risk of prolonged bleeding.

While other medications in the list, such as heparin and ibuprofen, can also influence bleeding risk, aspirin is particularly well-known for its anti-platelet effects and is widely recognized in both clinical practice and patient education for this property. Acetaminophen, on the other hand, does not affect platelet function and tends to have a lower risk of causing bleeding complications. Understanding these effects is crucial for safe medication administration and monitoring in patients who may be at risk for bleeding.
