Based on FDA | Is it safe for someone with a peanut or tree nut allergy to take clopidogrel, or does it contain any nut-derived ingredients?

Clopidogrel and nut allergies: what you need to know
Clopidogrel tablets do not list peanut or tree‑nut–derived ingredients in their official inactive ingredient lists, and most marketed formulations appear free of nut oils. ^{[1] [2]} That said, excipients can vary by manufacturer and country, so it’s wise to confirm the exact product label you receive from your pharmacy. ^[3]

What’s in clopidogrel?

• Clopidogrel’s active ingredient is clopidogrel bisulfate. ^[1]
• Common inactive ingredients (excipients) in various approved products include mannitol, microcrystalline cellulose, croscarmellose sodium or crospovidone, colloidal silicon dioxide, magnesium or zinc stearate, hypromellose (film coat), polyethylene glycol, titanium dioxide, iron oxide red, and lactose. ^{[1] [2] [3]}
• Some formulations include hydrogenated castor oil (from castor beans, which are not tree nuts) as a lubricant in the coating. ^[4]

These listed excipients do not include peanut oil or tree‑nut oils. ^{[1] [2]}

Why excipient checks still matter

Pharmaceutical excipients can come from food sources, and trace proteins have been detected in certain excipients like lactose or edible oils in general, which is why label verification is important for individuals with severe food allergies. ^[5] Manufacturers may formulate clopidogrel differently, so verifying the specific National Drug Code (NDC) or brand/generic supplier can help ensure no unexpected ingredients are present. ^[6]

Castor oil vs. tree nuts

Some clopidogrel products list hydrogenated castor oil, a derivative of castor beans (Ricinus communis). ^[4] Castor beans are botanically distinct from tree nuts and peanuts, and castor oil is not considered a peanut or tree‑nut ingredient. ^[4] While castor oil allergy is rare, anyone with a known castor allergy should avoid formulations containing it. ^[4]

Practical safety guidance

• Based on official labeling, clopidogrel tablets generally do not contain peanut or tree‑nut excipients. ^{[1] [2]}
• Because excipient lists differ among manufacturers, ask your pharmacist to print the exact ingredient list (from the NDC they dispense) to confirm absence of nut-derived oils. ^[3]
• If you have a history of severe anaphylaxis to edible oils or unusual excipient reactions, you can request a clopidogrel product that does not include hydrogenated castor oil. ^[4]
• Monitor for any signs of allergic reaction (hives, swelling, breathing difficulty) and seek urgent care if they occur; most clopidogrel “allergies” present as delayed skin rashes unrelated to food excipients and are managed differently. ^{[7] [8]}

Summary table: clopidogrel excipients and nut relevance

• Excipient: Lactose (milk sugar)

  • Typical role: Filler
  • Nut relevance: Not a nut product; may contain trace milk proteins (relevant to milk allergy, not nut allergy). ^{[2] [5]}

• Excipient: Mannitol, microcrystalline cellulose, croscarmellose sodium/crospovidone, colloidal silicon dioxide

  • Typical role: Fillers/disintegrants/glidants
  • Nut relevance: Not nut derived. ^{[1] [2]}

• Excipient: Hypromellose, polyethylene glycol, titanium dioxide, iron oxide red

  • Typical role: Film coat/colorants
  • Nut relevance: Not nut derived. ^{[1] [2]}

• Excipient: Hydrogenated castor oil

  • Typical role: Lubricant in some coatings
  • Nut relevance: From castor bean, not a tree nut or peanut; avoid only if you have known castor allergy. ^[4]

Bottom line

• Evidence from multiple approved clopidogrel labels shows no peanut or tree‑nut ingredients are listed. ^{[1] [2] [3]}
• Because formulations vary, the safest approach is to verify the specific product’s inactive ingredients with your pharmacist and, if needed, select a formulation without hydrogenated castor oil. ^{[3] [4]}

If you ever experience a rash or other reaction after starting clopidogrel, clinicians usually consider a medication hypersensitivity pathway that is typically unrelated to food excipients and can often be managed without stopping clopidogrel. ^[7]
