Scopolia and Revefenacin

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

ANTICHOLINERGIC DRUGS

Why this applies to Revefenacin

Revefenacin falls under ANTICHOLINERGIC DRUGS — the group Scopolia interacts with.

The alkaloid constituents of scopolia, including hyoscyamine, scopolamine, and atropine, could potentiate the effects and adverse effects of anticholinergic drugs.
Severity Major 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

Here's the simple version: your inhaler, Yupelri (revefenacin), is itself an anticholinergic. It works by blocking acetylcholine to relax the airway muscles so you can breathe easier. Scopolia is loaded with its own anticholinergic compounds (atropine, hyoscyamine, and scopolamine). So you'd basically be stacking two things that do the same job, and the effects can add up.

When that happens, the typical anticholinergic side effects tend to get worse: dry mouth, blurred vision, constipation, trouble urinating, a faster heartbeat, and confusion, especially in older folks. This concern is based on how these drugs work rather than reported cases, but scopolia is a potent, unpredictable plant, so I'd steer clear. Please check with your pharmacist or doctor before combining them.

From our pharmacist’s overview on the Revefenacin page

“Revefenacin (Yupelri) is an inhaled anticholinergic that keeps airways open in COPD, and this list warrants genuine care rather than a quick skim. Of the 46 supplements on file, three carry a major rating, and most of the rest share revefenacin's drying, anticholinergic action, so combining them can stack up dry mouth, blurred vision,…”

About Scopolia

What is Scopolia?

Scopolia
  • Stomach and intestinal cramps
  • Motion sickness
  • Spasms and colic
  • Excess saliva or secretions
  • Pain relief (traditional)

Scopolia is a poisonous plant in the nightshade family that contains powerful anticholinergic alkaloids like atropine, hyoscyamine, and scopolamine. While these compounds are used in carefully measured prescription medicines, the raw plant is dangerous for self-treatment and should never be used without a doctor's supervision.

About Revefenacin Oral Inhalation

What Is Revefenacin Oral Inhalation Used For?

Brand name: Yupelri

Yupelri (revefenacin) inhalation solution is approved for the maintenance treatment of COPD (chronic obstructive pulmonary disease) in adults. It is used every day to help keep airways open and make breathing easier over the long term.

Yupelri is not a rescue inhaler — it will not relieve a sudden COPD flare-up or acute breathing attack. A separate short-acting bronchodilator is needed for those situations.
