If you are already experiencing an ACE inhibitor-induced cough and are using topical Capsaicin, be aware that it may worsen this symptom. Inform your doctor. In some cases, switching to an ARB may be considered.
Why this interaction occurs
ACE inhibitors increase bradykinin levels, causing a dry cough in susceptible patients. Capsaicin activates TRPV1 receptors in airway sensory neurons. Combined, they may synergistically sensitize cough reflex pathways, worsening ACE-inhibitor-induced cough.
Evidence
Evidence level: moderate.
Reported safety data
The FDA’s adverse event reporting system (FAERS) has received 5,692,394 reports mentioning ACE Inhibitors (e.g., Enalapril). This reflects reported cases involving the medication in general — not confirmed causation, and not specific to the ACE Inhibitors (e.g., Enalapril) + supplement combination on this page.
FAERS reports are voluntary and cannot prove that a drug caused an event. Do not use report counts to assess the safety of this specific drug-supplement pair.
