American Hellebore and Perindopril Erbumine

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

Major

Antihypertensive Drugs

Why this applies to Perindopril Erbumine

Perindopril Erbumine 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 key thing to know: American hellebore is a genuinely toxic plant, and on its own it can sharply lower your blood pressure and slow your heart rate. Perindopril (Aceon) is already working hard to bring your blood pressure down. Put the two together and those effects stack on top of each other.

What that can look like in real life is feeling dizzy or lightheaded, fainting, an unusually slow or pounding heartbeat, or feeling weak and drowsy. Because hellebore can cause real harm even in small amounts, I'd steer clear of it entirely while you're on perindopril. Please don't start or stop anything on your own. Talk with your pharmacist or doctor first.

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.
