Pu-erh Tea and Olodaterol Hydrochloride

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

Moderate

BETA-ADRENERGIC AGONISTS

Why this applies to Olodaterol Hydrochloride

Olodaterol Hydrochloride falls under BETA-ADRENERGIC AGONISTS — the group Pu-erh Tea interacts with.

Theoretically, concomitant use of large amounts of pu-erh tea might increase cardiac inotropic effects of beta-agonists.
Pu-erh tea contains caffeine. Caffeine can increase 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

Striverdi (olodaterol) is a long-acting inhaler that opens up your airways by stimulating beta receptors. Pu-erh tea naturally contains caffeine, and caffeine is a mild stimulant of its own. Putting the two together could, in theory, add up and give your heart a little extra push. That might show up as a faster heartbeat, a fluttering or pounding feeling in your chest, jitteriness, or feeling wired.

The good news is this concern is based on pharmacology, not strong human studies, and a normal cup or two of pu-erh is unlikely to cause problems for most people. The bigger question is concentrated caffeine or drinking large amounts all day. If you notice palpitations, tremor, or a racing heart, check in with your pharmacist or doctor before changing anything.

From our pharmacist’s overview on the Olodaterol Hydrochloride page

“Olodaterol (Striverdi Respimat) is a long-acting inhaled bronchodilator for COPD, and because it stimulates beta receptors in the heart as well as the lungs, its supplement list deserves more than a quick skim. Seven of the 147 interacting ingredients are rated major, and most of those, ephedra among them, can prolong the QT interval,…”
