Injectable anticoagulation indications include which scenario?

• A. Routine dental prophylaxis
• B. Acute treatment of ACS
• C. Long-term Afib prophylaxis
• D. Chronic venous insufficiency management

Answer: (B)

Injectable anticoagulants are used when rapid, short-term anticoagulation is needed in acute, high-thrombotic-risk situations. In acute coronary syndrome, parenteral anticoagulation helps prevent further thrombus formation and works alongside antiplatelet therapy and reperfusion strategies. That makes it the appropriate indication among the options.

Routine dental prophylaxis isn’t an indication for starting injectable anticoagulation; dental care focuses on local hemostasis and may require adjusting existing anticoagulation, but it doesn’t require initiating injectable anticoagulation. Long-term atrial fibrillation prevention is typically managed with oral anticoagulants (warfarin or DOACs) rather than injectable agents. Chronic venous insufficiency is managed with compression and other non-anticoagulation approaches.
