Danshen 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 Danshen interacts with.

Theoretically, taking danshen with antihypertensive drugs might increase the risk of hypotension.
Animal research suggests that danshen can produce dose-dependent hypotensive effects. Furthermore, concomitant use with captopril appears to potentiate this effect.
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 lowers fluid and can also nudge your blood pressure down. Danshen, on its own, has shown blood-pressure-lowering effects in animal studies. So the worry is simply that the two together could push your pressure lower than intended.

If that happened, you might feel dizzy, lightheaded, or woozy when you stand up, or notice more fatigue. I want to be honest about the strength of this, though: it's a theoretical concern based mostly on lab and animal data, not solid human studies, so it may never cause a real problem for you. Still, since both can affect blood pressure, please run it by your pharmacist or doctor before combining them, especially if you already feel lightheaded.

About Danshen

What is Danshen?

Danshen
  • Heart and circulation support
  • Angina (chest pain)
  • High blood pressure
  • Anxiety and stress
  • Liver health

Danshen is a root used in traditional Chinese medicine, mainly for heart and circulation problems. Some early research is promising, but the evidence is not strong enough to confirm it works for any condition, and it may affect blood clotting. Talk to a pharmacist or doctor before using it, especially if you take other medicines or have 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.
