Glycopyrrolate Side Effects and Management

Introduction to Glycopyrrolate Side Effects

• Glycopyrrolate commonly causes anticholinergic side effects, including blurring of vision, dry mouth, dilated pupils, urinary retention, and sedation, as reported by the American Academy of Otolaryngology-Head and Neck Surgery 1, 2

Common and Serious Side Effects

• Vomiting, flushing of the face or skin, nasal congestion, headache, swollen sinuses, and problems urinating or difficulty starting urination are associated with glycopyrrolate use, according to Diabetes Care 3
• Significant toxicity and withdrawal effects can occur when glycopyrrolate is used for more than several days, as noted by the American Academy of Otolaryngology-Head and Neck Surgery 1

Monitoring and Management

• When used for end-of-life secretion management, monitoring for reduction in respiratory secretions and improved comfort is recommended, as suggested by Praxis Medical Insights 4
• Typical dosing for respiratory secretion management at end-of-life is 0.2-0.4 mg IV or subcutaneously every 4 hours as needed, according to Praxis Medical Insights 4

Advantages Over Other Anticholinergics

• Glycopyrrolate has a quaternary ammonium structure that limits its ability to cross the blood-brain barrier, resulting in fewer central nervous system side effects compared to other anticholinergics, and is less likely to cause delirium compared to other anticholinergics like scopolamine when used for end-of-life congestion management, as reported by Praxis Medical Insights 4
