I have been diagnosed with neurogenic bladder. i also have asthma, and use inhalers to control it. they are aremuscarinic antagonists. association?

If you're using an: inhaler that contains an anticholinergic agent, you are, by definition, taking a muscarinic antagonist. Muscarinic antagonists don't cause neurogenic bladder; in fact, drugs like these are often used to treat the condition. It's unlikely that you're getting a therapeutic dose via an inhaler; you would likely need an oral med like oxybutinyn to improve symptoms of neurogenic bladder. Dr. Anne

This is a good ?: You are correct, muscarinic antagonists are fairly often used in overactive bladder: oxybutynin, flavoxate. They may help reduce bladder spasm. These drugs are also used in asthma, i.e. ipratropium, but maybe not as much. More likely beta-agonists and steroids in asthma. I might avoid; wouldn't worry about dangerous interaction but caution with dosing as potential increased effects for either/both
