Does your school-age child still wet the bed regularly, especially alongside daytime accidents? Researchers in China recently studied whether a medication called mirabegron might help. The study involved 31 children with non-monosymptomatic nocturnal enuresis (NMNE)—bedwetting that occurs together with daytime bladder control issues.
The children received mirabegron alongside other therapies for 12 weeks. This combination approach tested whether the medication, which relaxes bladder muscle and increases storage capacity, could improve symptoms.
Nine out of ten children improved, but the mix of treatments matters
The results were striking: 28 out of 31 children (90.3%) showed meaningful improvement in bedwetting episodes and daytime accidents. Medical tests showed their bladders could hold more urine and were less tense. Importantly, no serious side effects were reported during the study period.
This is encouraging but not yet conclusive proof
Here's the important catch: because all children received several therapies at once—not just mirabegron alone—researchers cannot say exactly how much improvement came from the medication versus the other treatments. The study also reviewed medical records after the fact rather than carefully comparing mirabegron against other options in a controlled way. Think of this as a promising first signal, not yet definitive proof.
What Singapore parents should do now
- Start with evidence-based basics: bladder training, scheduled toilet visits, limiting evening fluids, and bedwetting alarms work for many children first.
- Get your child properly assessed by a paediatrician or specialist who can evaluate whether their bedwetting links to bladder capacity or overactive muscles.
- Discuss mirabegron only as a potential option after standard approaches, and only under specialist guidance tailored to your child.
