Can Rivaroxaban, Aspirin, and Clopidogrel Be Given Together?

Yes, rivaroxaban can be given together with aspirin and clopidogrel as triple therapy, but only in highly specific clinical scenarios and for strictly limited durations—typically 1 week to 1 month post-PCI in patients with atrial fibrillation requiring anticoagulation, after which aspirin should be discontinued. 1

Clinical Context Determines the Answer

The appropriateness of combining all three agents depends entirely on whether the patient has atrial fibrillation (AF) requiring anticoagulation or stable atherosclerotic disease without AF.

Scenario 1: Atrial Fibrillation + Recent PCI/Stenting

Triple therapy (rivaroxaban + aspirin + clopidogrel) is appropriate only immediately post-PCI and must be minimized:

• Rivaroxaban 15 mg once daily (or 10 mg if CrCl 30-49 mL/min) plus aspirin plus clopidogrel should be considered for 1 month maximum after coronary stent implantation, irrespective of stent type 1

• Extension to 6 months may be considered only in patients with high ischemic risk due to acute coronary syndrome or complex anatomical/procedural characteristics that clearly outweigh bleeding risk 1

• After the initial 1-6 month period, discontinue aspirin and continue dual therapy with rivaroxaban 15 mg daily plus clopidogrel 75 mg daily for up to 12 months total 1

• At 12 months post-PCI, discontinue clopidogrel and continue rivaroxaban monotherapy for stroke prevention 1

Critical dosing detail: When rivaroxaban is used in combination with aspirin and/or clopidogrel in AF patients, rivaroxaban 15 mg once daily may be used instead of the standard 20 mg dose 1

Alternative to triple therapy: Dual therapy with clopidogrel 75 mg/day and rivaroxaban 15 mg should be considered as an alternative to 1-month triple therapy in patients in whom bleeding risk outweighs ischemic risk—this means omitting aspirin entirely from the start 1

Scenario 2: Stable Atherosclerotic Disease WITHOUT Atrial Fibrillation

The combination uses a completely different rivaroxaban dose and indication:

• Rivaroxaban 2.5 mg twice daily (not 15-20 mg once daily) plus aspirin 75-100 mg daily is indicated for high ischemic risk patients with stable coronary or peripheral artery disease 1, 2

• Clopidogrel should NOT be added to this regimen outside the immediate post-PCI period (first 6-12 months) 1, 2

• This low-dose rivaroxaban 2.5 mg BID regimen reduced major cardiovascular events with a number-needed-to-treat of 77 and number-needed-to-harm for major bleeding of 84 in the COMPASS trial 1, 2

• Do not use rivaroxaban 2.5 mg BID within the first 12 months after PCI—standard dual antiplatelet therapy (aspirin + clopidogrel) is required during this period 2

Bleeding Risk Is the Limiting Factor

Triple therapy increases bleeding substantially:

• The 90-day bleeding risk on triple therapy was increased compared with oral anticoagulation plus a single antiplatelet agent (HR 1.47,95% CI 1.04-2.08) 1

• Rivaroxaban 2.5 mg BID in triple therapy with aspirin and clopidogrel is safer in terms of bleeding risk than triple therapy with warfarin, but still carries significant hemorrhagic risk 1

• Major bleeding increases from 1.9%/year with aspirin alone to 3.1%/year when rivaroxaban 2.5 mg BID is added, though intracranial and fatal bleeding did not significantly increase 2

Absolute contraindications to triple therapy:

• History of intracranial hemorrhage at any time 2
• Recent gastrointestinal bleeding (≤6 months) or active peptic ulcer 2
• Hemoglobin <10 g/dL 2
• Liver cirrhosis with portal hypertension 2
• Severe renal impairment (CrCl <15 mL/min) 2

Critical Pitfalls to Avoid

Do NOT use ticagrelor or prasugrel as part of triple therapy with aspirin and oral anticoagulation—only clopidogrel has adequate safety data in this setting 1

Do NOT confuse the two rivaroxaban dosing regimens:

• 15 mg once daily = for AF stroke prevention when combined with antiplatelet therapy 1, 3
• 2.5 mg twice daily = for stable atherosclerotic disease combined with aspirin (NOT for AF stroke prevention) 1, 2

Do NOT continue triple therapy beyond the specified duration—prolonged triple therapy markedly increases bleeding without proven additional ischemic benefit 1

Do NOT add aspirin to rivaroxaban + clopidogrel beyond 1 month in AF patients post-PCI unless there is documented very high ischemic risk that clearly outweighs bleeding risk 1

Practical Algorithm

Step 1: Does the patient have atrial fibrillation requiring anticoagulation?

• YES → Go to Step 2
• NO → Go to Step 3

Step 2 (AF patients): Did the patient undergo PCI/stenting within the past 12 months?

• Within 1 month: Rivaroxaban 15 mg daily + aspirin + clopidogrel (triple therapy) 1
• 1-12 months: Rivaroxaban 15 mg daily + clopidogrel (dual therapy, aspirin discontinued) 1
• Beyond 12 months: Rivaroxaban 15-20 mg daily alone (all antiplatelets discontinued) 1

Step 3 (No AF): Is the patient within 12 months of PCI?

• YES: Aspirin + clopidogrel (standard DAPT); do NOT add rivaroxaban 2
• NO, and high ischemic risk: Consider aspirin 75-100 mg daily + rivaroxaban 2.5 mg BID (do NOT add clopidogrel) 1, 2

Monitoring Requirements

• Assess renal function at baseline and at least annually (more frequently if CrCl <60 mL/min) 2, 3
• Check complete blood count including hemoglobin and platelets at baseline 2
• Reassess both bleeding and ischemic risk at every clinical visit 1, 2
• Add proton pump inhibitor for patients with gastrointestinal bleeding risk factors 1, 3
