Drug Interactions between bethanechol and glycopyrrolate / neostigmine

Ask your doctor before using neostigmine together with glycopyrrolate. Using these medications together can cause increasing muscle weakness. In addition, such use may mask the less serious, gastrointestinal signs of glycopyrrolate overdose and lead to difficulty breathing, chest pain, and possibly death. If your doctor prescribes these medications together, you may need a dose adjustment or special tests to safely use both medications. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
