Breadfruit and Bumetanide (Oral)

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

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Bumetanide (Oral)

Bumetanide (Oral) falls under ANTIHYPERTENSIVE DRUGS — the group Breadfruit interacts with.

Theoretically, concomitant use with antihypertensive drugs might increase the risk of hypotension. Animal research shows that breadfruit leaf extract can decrease heart rate and weaken the force of heart muscle contractions, which may lower blood pressure.
Some antihypertensive drugs include captopril (Capoten), enalapril (Vasotec), losartan (Cozaar), valsartan (Diovan), diltiazem (Cardizem), amlodipine (Norvasc), hydrochlorothiazide (HydroDIURIL), furosemide (Lasix), and many others.
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: bumetanide (Bumex) is a strong water pill that pulls extra fluid out of your body, and one of its common effects is lowering your blood pressure. Concentrated breadfruit leaf products may nudge blood pressure down too. In animal studies, breadfruit leaf extract slowed the heart rate and weakened the heart's pumping a little, so pairing the two could add up to more of a drop than you'd expect.

If that happened, you might feel dizzy, lightheaded, or faint, especially when standing up quickly. I'll be honest though, this is only a theoretical concern based on lab and animal work, not real patient cases. Eating breadfruit as food is very unlikely to matter. If you're considering leaf teas or extracts, check with your pharmacist or doctor first.

About Breadfruit

What is Breadfruit?

  • Source of nutrition and energy
  • High blood pressure
  • Diabetes and blood sugar support
  • Inflammation and joint discomfort
  • Skin conditions

Breadfruit is a starchy tropical fruit eaten as a staple food, and its leaves are used in traditional medicine for conditions like high blood pressure and diabetes. As a food it is nutritious and generally safe, but the medicinal use of leaf teas or extracts has very little human research to back it up. Talk with your pharmacist or doctor before using breadfruit products for a health condition.

About Bumetanide

What Is Bumetanide Used For?

Brand name: Bumex

Bumetanide treats edema — excess fluid that builds up in the body — caused by congestive heart failure, hepatic (liver) disease, and renal (kidney) disease, including a condition called nephrotic syndrome. This applies to the oral tablets (bumetanide and Bumex), the injection (Bumetanide Injection), and the nasal spray.

Enbumyst (bumetanide nasal spray) is specifically approved for these same uses in adults. Enbumyst is not intended for long-term use and should be switched to an oral diuretic as soon as practical.
