About oxybutynin

Oxybutynin is classed as an antimuscarinic (or anticholinergic) muscle relaxant. Oxybutynin is used to treat the symptoms of an overactive bladder, such as:

  • Urinary urgency (a sudden and urgent need to pee)
  • Urinary frequency (needing to pee more often than usual)
  • Urinary incontinence (wetting yourself)

Oxybutynin relaxes muscles around your bladder, allowing your bladder to hold more liquid, stopping you from needing to pee as often or as urgently.

NowPatient offers oxybutynin or the brand Ditropan as treatments for urinary incontinence only, following an online consultation with a prescribing clinician.
