What is glycopyrrolate?
Glycopyrrolate reduces the secretions of certain organs in the body.
Glycopyrrolate helps to control conditions such as peptic ulcers that involve excessive stomach acid production.
The injectable form of glycopyrrolate is also used to reduce saliva, nasal, lung, and stomach secretions and to help control heart rate during surgery.
Glycopyrrolate may also be used for purposes other than those listed in this medication guide.
Do not take glycopyrrolate if you have
- kidney disease;
- a blockage of your urinary tract (difficulty urinating);
- a blockage in your intestines, severe ulcerative colitis, or ulcerative colitis complicated by toxic megacolon;
- glaucoma; or
- myasthenia gravis.
Before taking this medication, tell your doctor if you have
- numbness or tingling in your hands or feet;
- liver disease;
- ulcerative colitis;
- thyroid problems;
- high blood pressure, an irregular heartbeat, or any type of heart disease;
- hiatal hernia or reflux disease;
- enlargement of the prostate; or

You may not be able to take glycopyrrolate, or you may require a lower dose or special monitoring during treatment if you have any of the conditions listed above.
It is not known whether glycopyrrolate will harm an unborn baby. Do not take glycopyrrolate without first talking to your doctor if you are pregnant.

Use alcohol cautiously. Alcohol may increase drowsiness and dizziness while you are taking glycopyrrolate.
Avoid becoming overheated in hot weather. Glycopyrrolate increases the risk of heat stroke because it causes decreased sweating.
