Dual Antiplatelet Therapy Precautions

**The following patient instructions summarize key precautions for dual antiplatelet therapy (DAPT) with aspirin and clopidogrel after coronary stent placement:** --- ## Patient Instructions: Dual Antiplatelet Therapy (Aspirin + Clopidogrel) After Stent Placement **Why This Matters:** Your stented artery is at risk of sudden blockage (stent thrombosis) if you stop these medications. Stopping both antiplatelet agents can cause stent thrombosis within as few as **7 days**, which carries a ~40% risk of heart attack or death[9]. **Critical Rules:** 1. **NEVER stop both aspirin and clopidogrel** without explicit instruction from your cardiologist. Even for procedures, one agent (usually aspirin) should continue[7][9]. 2. **Duration matters:** DAPT is recommended for at least **4 weeks** after bare-metal stents and **12 months** after drug-eluting stents[7]. 3. **Before any surgery or dental procedure**, inform all providers about your stents and blood thinners. Do not stop medications on your own. 4. **Watch for bleeding:** Report unusual bruising, black/tarry stools, or blood in urine. Seek emergency care for severe headache or vomiting blood. 5. **Take exactly as prescribed** — do not skip doses. Use a pill organizer or reminder app. **When to call 911:** Chest pain, shortness of breath, or fainting — these may signal stent blockage. --- *Disclaimer: This information is AI-generated based on current guidelines and is for educational purposes.
