Hi, Glycopyrrolate is a medication that is commonly used to treat excessive sweating, drooling, and other symptoms caused by certain medical conditions. While it is not typically associated with causing constant swallowing, it is possible that it could have this side effect in some individuals. If you are experiencing periods of constant swallowing while taking glycopyrrolate, it is important to speak with your healthcare provider. They can evaluate your symptoms and determine if they are related to the medication or if there is another underlying condition that could be causing them. In terms of your medical history, allergies to trees and grasses can certainly cause symptoms like nasal congestion and post-nasal drip, which could potentially contribute to excessive swallowing. However, it is also possible that there could be other factors at play. Regarding your mild osteoporosis, this condition typically does not cause symptoms like excessive swallowing. However, it is important to continue to manage your osteoporosis through lifestyle changes and medication as recommended by your healthcare provider to prevent further bone loss and reduce your risk of fractures. Overall, if you are experiencing any concerning symptoms while taking glycopyrrolate or at any other time, it is always a good idea to speak with your healthcare provider to ensure that you receive appropriate evaluation and treatment. Take care. Hope I have answered your question. Let me know if I can assist you further. Regards, Dr. Priyanka, General & Family Physician
