Sesame and Indomethacin

Here is the interaction we found between these two, with the evidence behind it.

Moderate

CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES

Why this applies to Indomethacin

Indomethacin falls under CYTOCHROME P450 2C9 (CYP2C9) SUBSTRATES — the group Sesame interacts with.

Theoretically, sesame might increase the levels and clinical effects of CYP2C9 substrates.
In vitro, sesame inhibits CYP2C9. However, this interaction has not been reported in humans.
Severity Moderate Likelihood Possible Evidence D

Interaction has been documented in animal or in lab research, or the interaction has been documented in humans but is limited to case reports or conflicting clinical research exists.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for indomethacin (Indocin). Your body clears this NSAID partly through a liver enzyme called CYP2C9. In test-tube studies, compounds in sesame appear to slow that same enzyme down. If that happened in real life, indomethacin could linger a bit longer and its effects (both good and bad) could be a touch stronger. With this drug, that mostly means watching for stomach upset, heartburn, indigestion, fluid retention, headache, or signs of stomach bleeding.

The important part: this is only seen in lab settings, never reported in actual people, so I wouldn't lose sleep over it. Ordinary sesame in your cooking is very unlikely to matter. If you take concentrated sesame supplements, just mention it to your pharmacist or doctor.

About Sesame

What is Sesame?

  • Heart and cholesterol health
  • Blood pressure support
  • Source of healthy fats and minerals
  • Skin and hair care (topical oil)
  • Antioxidant support
  • Cooking and nutrition

Sesame is a nutritious seed and oil widely used in cooking and traditional medicine, and it provides healthy fats, fiber, and antioxidant compounds called lignans. Some early research suggests sesame may modestly help with cholesterol and blood pressure, but the evidence is limited. Sesame is also a common, sometimes serious, food allergen, so people with seed allergies should be careful.

About Indomethacin

What Is Indomethacin Used For?

Brand names: Indocin, Indocin SR, Indo-Lemmon, Indomethagan, Tivorbex

Indomethacin oral suspension and rectal suppository forms (including Indocin oral suspension and Indocin suppositories) are used to treat moderate to severe rheumatoid arthritis (including acute flares), moderate to severe ankylosing spondylitis (spine inflammation), moderate to severe osteoarthritis, acute painful shoulder (bursitis and/or tendinitis), and acute gouty arthritis. Oral capsules — both immediate-release and extended-release — share these same approved uses, except that extended-release capsules are not approved for acute gouty arthritis.

Indomethacin for Injection (intravenous) is a completely separate use: it is given to premature infants to close a hemodynamically significant patent ductus arteriosus (a blood vessel near the heart that should close after birth but hasn't) when standard medical management has not worked.
