Wild Carrot and Diltiazem, Enalapril

These two interact in 2 distinct ways. Each one is explained separately below.

Why Are There 2 Interactions?

Wild Carrot interacts with whole categories of medication. Diltiazem, Enalapril falls into 2 of those categories, so it can interact with Wild Carrot in 2 different ways. We’ve listed each one below — your overall risk is driven by the most serious of them (Moderate).

Moderate

ANTIHYPERTENSIVE DRUGS

1 of 2

Why this applies to Diltiazem, Enalapril

Diltiazem, Enalapril 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

This combo pill pairs diltiazem (a calcium channel blocker that relaxes blood vessels and slows the heart) with enalapril (an ACE inhibitor). Together they lower your blood pressure. The concern here is mostly theoretical: in lab and animal work, the essential oil in wild carrot seed seems to have some effect on the heart and blood vessels that could, in large amounts, push against your blood pressure control.

In plain terms, taking a lot of concentrated wild carrot seed oil might make your pressure harder to manage, so you could notice your readings drifting or feel off. This is unproven and the evidence is weak. Eating ordinary carrots is not the issue. If you're thinking about wild carrot supplements, just check with your pharmacist or doctor first.

PHOTOSENSITIZING DRUGS

2 of 2

Diltiazem, Enalapril also falls under PHOTOSENSITIZING DRUGS.

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 with Teczem (the combo of diltiazem and enalapril) plus wild carrot. This isn't about your blood pressure pill becoming stronger or weaker. The concern is purely about your skin and the sun. Wild carrot contains plant oils that can make skin more sensitive to sunlight, and some blood pressure medicines can do the same. Put together, you might sunburn faster or more easily than usual.

I want to be honest: this is theoretical, based on how these compounds behave, not on solid human studies. So don't lose sleep over it. Just be a little extra careful with sun, wear sunscreen, and check in with your pharmacist or doctor before adding wild carrot.

From our pharmacist’s overview on the Diltiazem, Enalapril page

“Anyone taking Teczem (diltiazem with enalapril) for blood pressure should know that most of the 271 supplements with an interaction on file hit the same targets as the drug itself. The bulk either add to its blood-pressure-lowering effect or change how the body handles diltiazem, which is processed by an enzyme called CYP3A4.”

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.
