Wild Carrot and Mefenamic Acid

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

Moderate

PHOTOSENSITIZING DRUGS

Why this applies to Mefenamic Acid

Mefenamic Acid falls under PHOTOSENSITIZING DRUGS — the group Wild Carrot interacts with.

Theoretically, concomitant use might result in increased photosensitivity. Some drugs that cause photosensitivity include amitriptyline (Elavil), quinolones (Ciprofloxacin, others), sulfa drugs (Septra, Bactrim, others), and tetracycline.
Severity Moderate Likelihood Probable Evidence D

Interaction 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..

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

Here's the gist: wild carrot may make your skin more sensitive to sunlight, and mefenamic acid (Ponstel) can do the same thing on its own. When you put the two together, the worry is simply that you might burn more easily, get a rash, or notice a sunburn-like reaction after less sun exposure than usual. This isn't about the drug building up in your body or losing its punch for pain relief. It's really just an additive effect on your skin.

Keep in mind this is a theoretical concern based on how these plants and drugs behave, not strong human study evidence. Still, a little common sense helps: wear sunscreen, cover up, and limit strong midday sun. If you notice unusual skin reactions, check in with your pharmacist or doctor.

From our pharmacist’s overview on the Mefenamic Acid page

“Mefenamic acid (Ponstel), an NSAID mostly used for menstrual cramps and short-term pain, has a supplement list that earns genuine caution, and the five major-rated entries are where to start. Beer and wine are two of them, because alcohol plus any NSAID raises the risk of stomach and intestinal bleeding.”

About Wild Carrot

What is Wild Carrot?

Wild Carrot
  • Urinary and bladder complaints
  • Digestive upset and gas
  • Menstrual support
  • Supporting milk production
  • Mild diuretic (water pill) effect

Wild carrot is a traditional herb (the wild ancestor of the garden carrot) used mostly for urinary, digestive, and menstrual complaints. High-quality human studies are lacking, so its benefits are unproven, and it should be avoided in pregnancy because of traditional use to affect the uterus. Talk with your pharmacist or doctor before using it.
