Glycopyrronium, also known as glycopyrrolate, is a medication used to treat COPD, excessive saliva, and excessive sweating. It may be taken by mouth, by injection, applied to the skin, or inhaled. Effects may last for up to 12 hours. It is also available in combination with a long-acting beta-adrenoceptor agonist (LABA) and inhaled steroid.

Common side effects include dry mouth, urinary retention, blurry vision, large pupils, headache, confusion, sleepiness, and constipation. Other side effects may include allergic reactions and bronchospasm. Safety in pregnancy is unclear. It is an antimuscarinic. It does not generally cross the blood–brain barrier.

Glycopyrronium was approved for medical use in the United States in 1961. It is on the World Health Organization's List of Essential Medicines as an alternative to tiotropium. In the United Kingdom a month of inhaled medication costs the NHS about £28 as of 2021. In the United States the tablets are inexpensive.
