American Hellebore and Bumetanide

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

Antihypertensive Drugs

Why this applies to Bumetanide

Bumetanide falls under Antihypertensive Drugs — the group American Hellebore interacts with.

American hellebore can have potent cardiovascular effects due to the toxic steroid ester alkaloids it contains. The alkaloids in this plant notably reduce blood pressure even in small doses. Additionally, the alkaloids can exhibit cardiac depressant, bradycardic, and sedative effects. These alkaloids inhibit the inactivation of sodium-ion channels in excitable cells, particularly those regulating cardiac activity. Furthermore, American hellebore's alkaloids induce vasodilation and block beta-adrenergic activity, potentially influencing the effectiveness or side effects of antihypertensive medications (source https://pubmed.ncbi.nlm.nih.gov/5457326/). Patients should exercise caution and consult healthcare professionals before using American hellebore for any reason.
Severity Major Likelihood Likely Evidence A

Well-controlled human studies have demonstrated the likely existence of this interaction.

Dr. Brian Staiger, PharmD, BCPS
Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the thing to know if you take bumetanide (Burinex): this water pill already lowers your blood pressure and pulls fluid out of your body. American hellebore does its own number on your heart and blood vessels, dropping blood pressure and slowing the heartbeat all on its own. Stack the two together and those effects can pile up.

What that could look like in real life is dizziness, lightheadedness, fainting, or a heart rate that drops too low, especially when you stand up. Bumetanide isn't a prodrug, so this isn't about one changing how the other is broken down. It's simply two things pushing your blood pressure and pulse in the same downward direction. Honestly, American hellebore is genuinely poisonous, so please talk with your pharmacist or doctor before going near any product containing it.

About American Hellebore

What is American Hellebore?

American Hellebore
  • High blood pressure
  • Slowing heart rate
  • Toxemia of pregnancy (historical)
  • Convulsions (historical)
  • Pain relief (traditional)

American Hellebore (Veratrum viride) is a highly poisonous plant whose root contains toxic alkaloids that can cause dangerous drops in heart rate and blood pressure, even in small amounts. It is not a safe self-care supplement, and any non-homeopathic product carries a serious risk of poisoning. Do not use it without medical supervision, and talk to a pharmacist or doctor before considering any product that contains it.

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.
