What this interaction means in plain words
Bethanechol and Glycopyrrolate inhaled have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens

What to do
No routine change is needed. Monitor urinary symptoms if retention is the treatment target.
