Why Clopidogrel Is Prescribed
| Indication | Typical Duration |
|---|---|
| After coronary stent (drug-eluting) | 6-12 months dual therapy with aspirin, then aspirin alone |
| After heart attack (no stent) | 12 months dual therapy |
| After ischaemic stroke/TIA | Often long-term, sometimes combined short-term with aspirin |
| Peripheral artery disease | Long-term as alternative to aspirin |
Critical Warning — Never Stop Early
Stopping clopidogrel early after a stent is placed carries a very high risk of stent thrombosis (sudden clotting within the stent), which can cause a life-threatening heart attack. Always discuss with your cardiologist before stopping, even for planned surgery or dental work.Bleeding Risk Management
- Increased bruising and bleeding is expected and usually manageable
- Tell all healthcare providers (including dentists) that you're on clopidogrel before any procedure
- Report any unusual bleeding, black stools, or blood in urine promptly
- Combined with aspirin, bleeding risk is higher than either drug alone
Do Not Stop Before Discussing with CardiologyIf a dentist, surgeon, or other doctor suggests stopping clopidogrel for a procedure, always confirm with your cardiologist first — many procedures can be done safely while continuing treatment, and stopping incorrectly risks stent thrombosis or stroke.
Genetic Testing for EffectivenessSome people have a genetic variant (CYP2C19) that makes them poor metabolisers of clopidogrel, reducing its effectiveness. If you've had a clotting event despite taking clopidogrel correctly, ask your doctor about genetic testing or alternative antiplatelets (ticagrelor, prasugrel).
Can I take ibuprofen with clopidogrel?
Combining NSAIDs with clopidogrel increases bleeding risk, particularly stomach bleeding. Paracetamol is generally preferred for pain relief; discuss with your doctor if NSAIDs are needed.
What if I need dental surgery while on clopidogrel?
Most routine dental procedures (including extractions) can be done safely while continuing clopidogrel, with local measures to control bleeding. Discuss with your dentist and cardiologist.
Is clopidogrel the same as aspirin?
No — they work through different mechanisms but both prevent platelet clumping. They're often combined (dual antiplatelet therapy) for a defined period after certain cardiac events for maximum protection.
