Wild Carrot and Bendroflumethiazide, Nadolol

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. Bendroflumethiazide, Nadolol 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 Bendroflumethiazide, Nadolol

Bendroflumethiazide, Nadolol 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

Corzide is a combo blood pressure pill: bendroflumethiazide is a water pill (thiazide diuretic) and nadolol is a beta-blocker. Both work to bring your blood pressure down. The concern here is theoretical only. In lab and animal work, large amounts of wild carrot seed oil have shown so-called cardiotonic effects, meaning they could nudge things in a way that works against your blood pressure medicine.

In plain terms, big concentrated supplement doses might blunt how well Corzide controls your pressure. This is based on pharmacology, not human studies, so it's far from certain, and ordinary food amounts of carrot are not a worry. Still, if you're considering wild carrot supplements, check with your pharmacist or doctor first and keep an eye on your home blood pressure readings.

PHOTOSENSITIZING DRUGS

2 of 2

Bendroflumethiazide, Nadolol 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.

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 deal with Corzide (a combo of bendroflumethiazide, a water pill, and nadolol, a beta-blocker) alongside wild carrot. The bendroflumethiazide part is a thiazide-type diuretic, and these can make your skin more sensitive to sunlight, so you may sunburn faster than usual. Wild carrot is also thought to add a bit to that sun sensitivity. Put them together and the worry is simply that you could burn more easily on a sunny day.

This is a theoretical concern based on how these ingredients behave, not on strong human studies, so try not to overthink it. Just use everyday sun smarts: sunscreen, a hat, and shade. If you notice unusual burning or a rash, check in with your pharmacist or doctor before changing anything.

From our pharmacist’s overview on the Bendroflumethiazide, Nadolol page

“Green tea worries me most. In human studies it cut blood levels of nadolol by roughly 85 percent, enough to undermine Corzide (bendroflumethiazide with nadolol) as a blood pressure treatment, and it earns one of the 12 major ratings here.”

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.
