About Betmiga

Betmiga is manufactured by Astellas Pharma Ltd and contains mirabegron as its active ingredient. Mirabegron is a beta 3-adrenoceptor agonist 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)
  • Urgency incontinence (wetting yourself)

Mirabegron 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 Betmiga as a treatment for urinary incontinence only, following an online consultation with a prescribing clinician.
