Chlorella and Bumetanide

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

Moderate

PHOTOSENSITIZING DRUGS

Why this applies to Bumetanide

Bumetanide falls under PHOTOSENSITIZING DRUGS — the group Chlorella interacts with.

Theoretically, chlorella might have additive effects with photosensitizing drugs.
Chlorella has been reported to cause photosensitization. In five case reports, patients who had ingested chlorella exhibited swelling followed by erythematopurpuric lesions on sun-exposed areas of the body. Theoretically, concomitant use with photosensitizing drugs may exacerbate effects.
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 explains PharmD, Clinical Pharmacist

Here's the connection between these two. Bumetanide is a water pill, and like several diuretics it can make your skin more sensitive to sunlight, so you may sunburn more easily than usual. Chlorella has its own track record here too. In a handful of case reports, people taking it developed swelling and reddish-purple skin marks on areas exposed to the sun.

Put them together and, in theory, the sun-sensitivity could add up. I want to be honest though: this is based on pharmacology and a few case reports, not strong studies, so it's a possible concern, not a sure thing. If you take both, just be smart about sun protection (sunscreen, hats, covering up) and watch for unusual rashes or burning. Run it by your pharmacist or doctor before starting chlorella.

From our pharmacist’s overview on the Bumetanide page

“Bumetanide (Burinex) is a potent loop diuretic, a water pill that pulls off fluid quickly and takes potassium with it, so I treat its interaction list as one of the serious ones. Seven of the 218 ingredients on file carry a major rating, and those belong at the top of your reading.”

About Chlorella

What is Chlorella?

Chlorella
  • General nutrition and 'detox' support
  • Immune support
  • Liver and kidney support
  • Antioxidant and anti-inflammatory support
  • Cholesterol and heart health

Chlorella is a nutrient-rich freshwater green algae taken as a supplement for general wellness, immune support, and 'detox.' Some small studies suggest possible benefits for cholesterol, blood pressure, and immune markers, but the overall evidence is limited and not strong. It is generally well tolerated, but quality varies and it should be avoided during pregnancy and breastfeeding unless a doctor approves.

About Bumetanide

What Is Bumetanide Used For?

Brand name: Burinex

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.
