Summary
Glucagon slows gastrointestinal motility, and anticholinergics such as tiotropium do the same. Taken together they may add to constipation, abdominal discomfort or ileus. Systemic exposure to inhaled tiotropium is low, so the effect is usually modest.
What this interaction means in plain words
Glucagon intranasal and Tiotropium 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
Additive inhibition of gastrointestinal motility through glucagon's smooth muscle relaxation and muscarinic receptor blockade.
What to do
No routine change is needed; monitor for constipation or reduced bowel activity, particularly in patients with existing gastrointestinal obstruction or dysmotility.

- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
