When you take oxybutynin, a medication used to treat overactive bladder by relaxing bladder muscles. It's also known as Ditropan, and while it helps with frequent urges and leaks, it often slows down your digestive system too. That’s because oxybutynin is an anticholinergic, a class of drugs that block acetylcholine, a nerve signal that controls muscle movement—including in your gut. Less signal means slower digestion, which leads to constipation, a common and sometimes stubborn side effect where bowel movements become infrequent, hard, or painful.
It’s not rare. In fact, up to 1 in 5 people on oxybutynin report constipation, and for some, it’s the main reason they stop taking it. This isn’t just about being uncomfortable—it can lead to bloating, nausea, even bowel obstruction if ignored. The problem gets worse if you’re older, already prone to slow digestion, or taking other meds like painkillers or antidepressants that also slow your gut. You can’t just wait it out. Small changes matter: drinking more water, eating fiber-rich foods like oats, beans, or prunes, and moving your body daily—even a short walk—can help. If you’re on oxybutynin and haven’t had a bowel movement in three days, it’s not normal. Talk to your doctor. They might adjust your dose, suggest a stool softener, or switch you to a different bladder med like mirabegron, which doesn’t hit your gut as hard.
