Cola Nut and Fluticasone, Salmeterol

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

Moderate

BETA-ADRENERGIC AGONISTS

Why this applies to Fluticasone, Salmeterol

Fluticasone, Salmeterol falls under BETA-ADRENERGIC AGONISTS — the group Cola Nut interacts with.

Theoretically, the caffeine in cola nut might increase the clinical effects of beta-adrenergic agonists.
Cola nut contains caffeine. Theoretically, concomitant use of large amounts of caffeine might increase the cardiac inotropic effects of beta-agonists.
Severity Moderate Likelihood Probable Evidence D

Interaction has not been documented in well-controlled studies, however, the interaction has been demonstrated in some small human studies or in controlled animal studies in conjunction with multiple case reports..

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

Advair is a two-in-one inhaler. The salmeterol part is what matters here: it's a long-acting beta-agonist, the same family of medicines that can speed up your heart and sometimes cause a jittery, shaky feeling. Cola nut is basically a caffeine source, and caffeine is a stimulant too. So in theory, stacking the two could nudge your heart to work a little harder, leaving you more prone to a racing or pounding heartbeat, tremor, nervousness, or trouble sleeping.

I want to be honest about the strength of this: it's a theoretical concern based on how these compounds work, not solid human proof, and it would mainly apply to large, concentrated cola nut doses rather than a normal cup of coffee or tea. If you notice your heart fluttering or feel extra wired, check in with your pharmacist or doctor before changing anything.

From our pharmacist’s overview on the Fluticasone, Salmeterol page

“Advair Diskus (fluticasone and salmeterol) pairs an inhaled steroid with a long-acting bronchodilator for asthma and COPD, and its supplement list deserves genuine vigilance, with seven major-rated entries sitting at the top. Most of the 141 ingredients on file, 121 of them, act on the CYP3A4 enzyme that clears these drugs.”

About Cola Nut

What is Cola Nut?

Cola Nut
  • Energy and alertness
  • Mental focus
  • Physical performance
  • Weight loss support
  • Traditional digestive aid

Cola nut is a caffeine-containing seed from West Africa used mainly as a natural stimulant for energy and alertness. Most of its effects come from caffeine, and strong human evidence for specific health benefits is limited. Because of its caffeine content, people sensitive to stimulants and those who are pregnant or have heart conditions should be cautious.
