Urologists publish a new guide on safer treatments for bladder challenges in Parkinson’s

A brand new medical review published in the Irish Journal of Medical Science in late 2026 has finally set out clear rules for managing bladder issues in people with Parkinson’s. Researchers Daniel Peter McNicholas, Jaraspong Vuthiwong, and Johan Gani recognized that although an overactive bladder is one of the most frustrating aspects of the condition, bladder specialists often lacked a dedicated rulebook on how to treat it safely. By bringing together expert opinions and the latest medical studies, the team has created a practical roadmap to help doctors and the people they support make much better decisions. A Smarter First Step for Overactive Bladders For people living with Parkinson’s, the most common urinary issue is a bladder muscle that squeezes too often, creating a sudden urge to rush to the toilet even when the bladder is nearly empty. Historically, doctors have prescribed a class of medications called anticholinergics as the very first treatment to calm these spasms down. However, the authors of this new guide argue it is time to change that habit. Anticholinergic drugs carry a heavy burden of side effects, including dry mouth, constipation, and most importantly, confusion and memory problems. Instead, the researchers recommend starting with a newer, gentler class of drugs known as beta three agonists, which relax the bladder muscle effectively without clouding the mind. When Tablets Are Not Enough When daily tablets do not quite do the trick, bladder injections offer a reliable next step. The review confirms that using Botulinum toxin A, commonly known as Botox, directly in the bladder wall is both safe and effective for people with Parkinson’s. By recommending a sensible starting dose of 100 units, specialists can calm an overactive bladder for several months at a time without causing the muscle to become too weak to empty properly. Knowing the Difference Before Considering Surgery One of the most important insights in this paper highlights how a bladder behaves in Parkinson’s compared to a rarer, related condition called Multiple System Atrophy, or MSA. While someone with Parkinson’s typically has a bladder that squeezes too frequently but still empties almost completely, a person with MSA often struggles with a bladder and urinary valve that fail to coordinate, leaving a large amount of urine behind after visiting the bathroom. Getting this distinction right is crucial when someone has a physical blockage, such as an enlarged prostate. The authors confirm that surgery to clear a blockage is safe for people with Parkinson’s, provided careful bladder pressure tests called urodynamics are carried out beforehand. In contrast, this type of surgery should be avoided in MSA, and if there is any doubt about which condition a person has, the urologist should speak directly with a neurologist before operating. Tackling Nighttime Trips and Medication Clashes Waking up multiple times in the night to use the bathroom is exhausting, and trying to hurry in the dark while stiff or slow significantly raises the risk of a fall. The researchers emphasize that treating nighttime bladder issues cannot rely on urology tablets alone. True improvement comes from working alongside the neurology team to fine tune evening Parkinson’s medications so that mobility remains smooth overnight, alongside making practical changes at home to keep the path to the bathroom safe and accessible. Finally, the review shines a light on a clever catch involving blood pressure medication. Many people with Parkinson’s experience a sudden drop in blood pressure when they stand up, which doctors frequently treat with a tablet called Midodrine. While Midodrine is great for keeping blood pressure steady and preventing dizziness, it works by tightening muscles in blood vessels, and it can accidentally tighten the muscle at the exit of the bladder too. This makes it very difficult to pass urine. If this happens, the guide advises speaking to a neurologist about switching to a different blood pressure medicine, or working with a urologist to treat the blockage directly so that managing one symptom does not create another.
