More information
"Betmiga is typically prescribed for adults experiencing overactive bladder syndrome to manage symptoms like urgency, frequency and urge incontinence. Unlike some traditional treatments, it uses the active substance mirabegron to relax bladder muscles, allowing the bladder to store more urine comfortably and reducing the sudden, strong need to urinate." - Rachael Clarke MRCPharm MFRPSI FRSPH (GPHC Number: 2061366)

Betmiga is a modified-release medication designed to alleviate the symptoms of overactive bladder syndrome (OAB) in adults. It specifically targets the involuntary contractions of the bladder muscle that lead to a frequent or sudden need to urinate. By reducing these contractions, the treatment helps patients manage their symptoms effectively throughout the day and night.
The active ingredient in this medication is mirabegron, which belongs to a class of drugs known as beta-3 adrenoceptor agonists. Each prolonged-release tablet is formulated to release this substance slowly into your system. This allows for a steady effect on the bladder muscles rather than a sudden peak in medication levels.
Many users report a significant improvement in their quality of life after starting treatment, noting a reduction in the number of trips to the bathroom. While individual results vary, the treatment is often favoured by those who have previously struggled with the side effects of older antimuscarinic medications. Consistent use as directed by a prescriber is key to achieving the best results.
You should always read the Patient Information Leaflet (PIL) included in your medication pack for comprehensive details on usage and safety. The PIL contains vital information regarding the specific formulation of your tablets and a full list of ingredients. You can also access digital versions of the leaflet through our platform or the manufacturer's official documentation.
Betmiga works by binding to and activating beta-3 receptors located in the muscle cells of the bladder. This activation triggers the bladder's detrusor muscle to relax while the bladder is filling with urine. Consequently, the bladder can hold a larger volume of liquid, which decreases the frequency of urgent signals sent to the brain and reduces unwanted contractions.
Take one tablet daily at the same time each day to maintain a consistent level of medication in your bloodstream. The tablets should be swallowed whole with a glass of water and must not be crushed, chewed or divided, as this would interfere with the slow-release mechanism. You can take your dose with or without food, depending on your preference.
The standard starting dose for adults is typically 50mg taken once daily, though a lower dose of 25mg may be prescribed in certain circumstances. Your prescriber will determine the most appropriate strength for you based on your medical history, kidney function and liver health. Never exceed the dose recommended by your healthcare professional.
| Patient Group | Typical Daily Dose |
|---|---|
| Standard Adult | 50mg once daily |
| Renal/Hepatic Impairment | 25mg once daily |
Common side effects of mirabegron can include an increased heart rate (tachycardia) and urinary tract infections. While many people use the medication without significant issues, some may experience the following:
- Nausea or indigestion
- Constipation or diarrhoea
- Headaches or dizziness
- Palpitations (feeling your heartbeat)
You must not take Betmiga if you have severe uncontrolled high blood pressure, as the medication can further increase your readings. It is important to have your blood pressure checked regularly while using this treatment. Caution is also advised for those with a history of heart rhythm problems or severe liver and kidney disease. Always inform your prescriber of any other medications you are taking, particularly those for heart conditions or fungal infections.
Betmiga is often preferred over antimuscarinic drugs like solifenacin or oxybutynin because it typically causes less dry mouth and constipation. While both types of medication treat overactive bladder, they work on different receptors in the body. For some patients, a combination of both types of treatment may be recommended by a specialist if a single medication is not sufficiently effective.
How long does it take for Betmiga to work?
While some people notice an improvement within a few days, it can take between four to eight weeks to feel the full therapeutic benefits of the treatment. It is important to continue taking the medication daily as prescribed, even if you do not see immediate results.
Can I drink alcohol while taking this?
There is no known direct interaction between alcohol and mirabegron, but moderation is advised. Alcohol can act as a bladder irritant and may worsen symptoms of urgency and frequency, potentially reducing the overall effectiveness of your treatment.
What should I do if I miss a dose?
If you forget a dose, take it as soon as you remember unless your next dose is due in less than 6 hours. In that case, skip the missed dose and continue with your normal schedule. Do not take a double dose to make up for a forgotten tablet.
