Coltsfoot and Perindopril Erbumine

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

Moderate

ANTIHYPERTENSIVE DRUGS

Why this applies to Perindopril Erbumine

Perindopril Erbumine falls under ANTIHYPERTENSIVE DRUGS — the group Coltsfoot interacts with.

Theoretically, excessive doses of coltsfoot may interfere with antihypertensive or cardiovascular therapy.
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: perindopril (Aceon) is an ACE inhibitor that helps relax your blood vessels and bring your blood pressure down. The concern with coltsfoot is mostly theoretical, and it rests on weak, anecdotal reports. The idea is that large amounts of coltsfoot could work against your blood pressure medicine, potentially keeping your numbers higher than they should be.

Honestly, the bigger issue with coltsfoot isn't this interaction at all. The raw herb can contain compounds that are hard on your liver, so it's something I'd be cautious with regardless. Please don't change how you take your perindopril on your own. If you're thinking about coltsfoot, run it by your pharmacist or doctor first so they can check your blood pressure and keep you safe.

About Coltsfoot

What is Coltsfoot?

Coltsfoot
  • Cough
  • Sore throat
  • Bronchitis and congestion
  • Loosening mucus (expectorant)
  • Asthma symptoms

Coltsfoot is a traditional herb long used to soothe coughs and clear mucus, but solid human evidence for these uses is lacking. More importantly, the raw plant can contain liver-toxic pyrrolizidine alkaloids, so it carries real safety concerns and is best avoided unless you use a product certified to be free of these compounds.
