Which medication should be avoided to prevent worsening bleeding during dental procedures?

• A. NSAIDs should be avoided as they may worsen bleeding
• B. Antibiotics should be avoided
• C. Acetaminophen should be avoided
• D. Opioids should be avoided

Answer: (A)

During dental procedures, keeping bleeding under control is essential. NSAIDs interfere with how platelets clump together to form a clot. They inhibit cyclooxygenase, which reduces thromboxane A2 production, a key signal for platelet aggregation. This makes it harder for blood to stop bleeding, so taking NSAIDs around the time of a procedure can worsen bleeding. Acetaminophen, on the other hand, relieves pain without affecting platelets, so it doesn’t increase bleeding risk. Antibiotics and opioids don’t directly alter platelet function or hemostasis in a way that would worsen bleeding, so they aren’t implicated in increasing bleeding during dental work. Therefore, avoiding NSAIDs helps maintain better control of bleeding during procedures.
