Alfalfa and Ketoprofen

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

Moderate

PHOTOSENSITIZING DRUGS

Why this applies to Ketoprofen

Ketoprofen falls under PHOTOSENSITIZING DRUGS — the group Alfalfa interacts with.

Theoretically, concomitant use of alfalfa with photosensitizing drugs might have additive effects.
Animal research suggests that excessive doses of alfalfa may increase photosensitivity, possibly due to its chlorophyll content. It is unclear if this effect would be clinically relevant 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 ketoprofen: this NSAID can already make your skin more sensitive to sunlight, so a bad sunburn or a rash from less sun exposure than usual is a known side effect. Alfalfa contains chlorophyll, and in animal studies very large amounts seemed to bump up sun sensitivity too. Put the two together and, in theory, the sun-sensitizing effect could add up.

I want to be honest though: this is a theoretical concern based on pharmacology and animal data, not solid human proof, and it's rated moderate. Normal food amounts of alfalfa are unlikely to matter much. If you take concentrated alfalfa supplements while on ketoprofen, just be smart about sun protection and check with your pharmacist or doctor first.

  • 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.

From our pharmacist’s overview on the Ketoprofen page

“Bleeding is what worries me most with ketoprofen (Orudis, Oruvail Gel). As an NSAID, it already irritates the stomach lining and slows clotting, and 202 of the 252 supplements and herbs on this page can push that bleeding risk further.”

About Alfalfa

What is Alfalfa?

Alfalfa
  • High cholesterol
  • Digestive complaints
  • Menopausal symptoms
  • Arthritis and joint pain
  • General nutritional supplement

Alfalfa is a nutrient-rich legume that people use for high cholesterol, menopause symptoms, and general wellness, but solid human evidence for most of these uses is limited. It is best avoided by people with autoimmune diseases, those who are pregnant or breastfeeding, and anyone with a weakened immune system, and you should check with your pharmacist or doctor before trying it.

About Ketoprofen

What Is Ketoprofen Used For?

Brand names: Orudis, Oruvail Gel, Powergel, Oruvail Injection

Ketoprofen capsules (including the brand Orudis) are used to manage the signs and symptoms of rheumatoid arthritis and osteoarthritis, to treat pain, and to treat primary dysmenorrhea (painful menstrual periods).

Ketoprofen extended-release capsules are approved for rheumatoid arthritis and osteoarthritis only. Because of the way they slowly release the drug, ketoprofen extended-release capsules are not recommended for treating acute (sudden) pain.
