Which medication class requires caution during therapy due to bleeding risk?

• A. Anticoagulants
• B. Antiplatelets
• C. NSAIDs
• D. Diuretics

Answer: (C)

NSAIDs require caution because they affect how blood clots by altering platelet function and damaging the stomach lining, which can increase bleeding risk in therapy. Mechanism and context: NSAIDs inhibit cyclooxygenase enzymes, especially COX-1 in platelets, leading to reduced production of thromboxane A2. This impairs platelet aggregation, so bleeding can be prolonged or easier to provoke during therapy or after procedures. Since platelets don’t synthesize new COX enzymes, this effect lasts for the life of the platelet, contributing to a higher bleeding risk for several days after starting or increasing NSAID use. In addition, NSAIDs irritate the gastric mucosa and can cause gastritis or ulcers, further elevating the chance of GI bleeding, particularly in older adults or when combined with other bleeding-risk meds (like anticoagulants or steroids). Clinically, if a patient is taking NSAIDs, be vigilant for signs of bleeding (unusual bruising, black stools, vomiting blood), consider interactions with other meds, and plan rehab activities with awareness of the bleeding risk, adjusting pain management or choosing alternative therapies when appropriate.
