Capsicum and Perindopril Arginine, Amlodipine

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

Minor

ACE INHIBITORS (ACEIs)

Why this applies to Perindopril Arginine, Amlodipine

Perindopril Arginine, Amlodipine falls under ACE INHIBITORS (ACEIs) — the group Capsicum interacts with.

Theoretically, using topical capsaicin may increase the risk of ACE inhibitor-induced cough.
There is one case report of a topically applied capsaicin cream contributing to the cough reflex in a patient using an ACEI. However, it is unclear if this interaction is clinically significant.
Severity Minor Likelihood Unlikely Evidence D

Interaction has been demonstrated in animal or in lab research but has been shown not to occur in humans..

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

Here's the simple version. Your Prestalia contains perindopril, which is an ACE inhibitor. One well-known side effect of that whole drug class is a dry, tickly cough that just won't quit. Capsaicin, the active part of chili pepper, works on the same nerve pathways that control your cough reflex. So the theory is that using capsaicin (usually as a topical cream) might make that cough a little more likely or a bit more bothersome.

I want to be honest about how thin this evidence is. It comes from a single case report, and it's considered minor and unlikely to cause real trouble for most people. The amlodipine part isn't involved here. If you do start a new cough after using capsaicin, just mention it to your pharmacist or doctor before stopping anything.

About Capsicum

What is Capsicum?

  • Nerve pain (neuropathy)
  • Muscle and joint pain (arthritis)
  • Back pain
  • Digestive support
  • Cluster headache (intranasal)

Capsicum (chili pepper) contains capsaicin, which is best known and best studied as a topical treatment for certain types of pain. Topical capsaicin products are supported by reasonable evidence for some nerve and joint pain, but oral supplements are far less proven. Use it carefully, follow product directions, and talk to your pharmacist or doctor before starting.
