Wild Carrot and Felodipine

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

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Felodipine

Felodipine falls under ANTIHYPERTENSIVE DRUGS — the group Wild Carrot interacts with.

Theoretically, excessive doses of wild carrot seed oil might interfere with antihypertensive therapy due to cardiotonic effects.
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 short version: Felodipine is a calcium channel blocker that lowers your blood pressure by relaxing your blood vessels. The concern with wild carrot is that, in large concentrated doses, its seed oil may have mild heart-related (cardiotonic) effects that could work against your blood pressure medicine. In plain terms, this might blunt how well felodipine controls your numbers.

I want to be honest about the strength of this: it's theoretical, based on how the plant behaves in lab settings, not on real patient studies. Normal food-amount carrot won't cause trouble. Still, if you're considering concentrated wild carrot supplements, check with your pharmacist or doctor first, and keep an eye on your home blood pressure readings.

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.
