Sesame and Betamethasone

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

Minor

P-GLYCOPROTEIN SUBSTRATES

Why this applies to Betamethasone

Betamethasone falls under P-GLYCOPROTEIN SUBSTRATES — the group Sesame interacts with.

Theoretically, sesame might alter the transport of P-glycoprotein substrates.
In vitro research suggests that sesamin, a constituent of sesame, can inhibit the multi-drug transporter protein, P-glycoprotein. However, this interaction has not been reported in humans.
Severity Minor 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 sesame and betamethasone. Sesame contains a compound called sesamin, and in lab dish studies it can gently block a cellular pump called P-glycoprotein, which helps move certain drugs around your body. In theory, slowing that pump could let a little more betamethasone hang around, which might mean slightly stronger steroid effects.

In real life, I wouldn't lose sleep over this one. Your betamethasone is a cream or ointment you put on your skin, so very little gets into your bloodstream to begin with. This interaction has only been seen in test tubes, never in people, and normal amounts of sesame in food are very unlikely to matter. If you ever have questions, your pharmacist is happy to double-check with you.

What These Ratings Mean

Every interaction above is graded three ways — here’s the key to each label.

Severity how clinically significant the interaction is
Major

Minor

Generally not serious. Be aware of it and mention it to your pharmacist.

Likelihood how strong the evidence is that the interaction actually happens in people
  • LikelyWell-controlled human studies have demonstrated the likely existence of this interaction.
  • ProbableInteraction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports.
  • PossibleInteraction 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.
  • UnlikelyInteraction has been demonstrated in animal or in lab research but has been shown not to occur in humans.
Evidence the quality of the studies behind the rating (graded A–D)
  • AHigh-quality meta-analysis (quantitative systematic review).
  • BCase-control study.
  • CConsensus.

From our pharmacist’s overview on the Betamethasone page

“Betamethasone (Celestone, Diprolene) works by quieting the immune system, which is exactly why this list warrants a slow, careful read. More than fifty of the ingredients here are immune stimulants that can push back against the steroid, and another sizable group changes how much of the drug the body absorbs or holds onto.”

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.
