About Detrusitol

Detrusitol contains tolterodine tartrate, an antimuscarinic, as its active ingredient. It helps to reduce bladder muscle spasms and the urge to frequently urinate, caused by these spasms. Detrusitol 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)

Tolterodine relaxes muscles around your bladder, allowing your bladder to hold more liquid, stopping you from needing to pee as often or as urgently. It is available with a prescription as generic tolterodine or under brand names such as Detrusitol, and Neditol.

NowPatient offers generic tolterodine or the branded treatments for urinary incontinence only, following an online consultation with a prescribing clinician.
