What are the side effects associated with the anticholinergic medication ipratropium used for asthma?

The side effects associated with the anticholinergic medication ipratropium are effectively summarized by the phrase that describes classic anticholinergic effects: "can't see, can't pee, can't spit, and can't sh*t." This phrase highlights the following key side effects:

• "Can't see" refers to blurred vision, which can occur due to the medication's effect on the eye's ability to accommodate.
• "Can't pee" points to urinary retention, as anticholinergic medications can lead to difficulty in urination.
• "Can't spit" describes dry mouth (xerostomia), a common side effect due to reduced saliva production.
• "Can't sh*t" indicates constipation, as the decrease in gastrointestinal motility can lead to difficulty in bowel movements.

These effects arise from the anticholinergic action of ipratropium, which blocks the action of acetylcholine, leading to decreased glandular secretions and reduced smooth muscle tone in various body systems. Given these effects, it is crucial for healthcare providers to monitor and educate patients regarding potential side effects when prescribing ipratropium for asthma management.
