Betmiga, or Mirabegron, can alleviate the symptoms of an overactive bladder, better known as urinary incontinence. The active ingredient mirabegron has a relaxing effect on the muscles of the bladder. Doctors prescribe Betmiga for an overactive bladder. Symptoms associated with this disease include a frequent need to urinate, inability to hold urine (incontinence), and a sudden and violent desire to urinate. An overactive bladder can negatively affect daily life. Patients suffering from this often prefer to stay close to a bathroom all day or feel ashamed of their incontinence. With an overactive bladder, the pectoral muscle contracts involuntarily, making you feel like your bladder is full, even if it isn't. Betmiga relaxes the overactive bladder muscle so that the bladder can absorb more urine before you feel like urinating again. This will alleviate complaints. Tablets generally work within a few hours.

People also ask

What is Betmiga / Mirabegron?

Betmiga contains the active ingredient mirabegron. It is a medicine that relaxes the smooth muscle of the bladder (called a beta 3 adrenergic receptor agonist), which reduces the symptoms associated with overactive bladder.

How does Betmiga tablets and Mirabegron tablets work?

The active ingredient in Betmiga, mirabegron, is a beta-3 adrenergic receptor agonist. It works by binding to beta-3 receptors found in the muscle cells of the bladder and activating them. Experimental studies have shown that once activated, the receptors beta-3s cause the bladder muscles to relax. It is estimated that this increases the bladder capacity and alters the way it contracts, which in turn results in a less number of contractions and therefore a decrease in involuntary urination.

What are the benefits of taking it?

Betmiga / Mirabegron is used to treat symptoms of overactive bladder in adults who:

  • suddenly need to empty their bladder (called an emergency)
  • they have to empty their bladder more often than normal (called an increase in urinary frequency)
  • are unable to control themselves when their bladder is full (called urge incontinence)

How do I use it and its dosage?

Always use this medicine exactly as your doctor has told you. If in doubt, consult your doctor or pharmacist again.

The recommended dose is one 50 mg tablet orally once daily. If you have kidney or liver problems, your doctor may need to reduce the dose to one tablet of the whole. Do not crush or chew the tablet. Betmiga can be taken with or without food.

If you take more Betmiga than you should

If you take more tablets than prescribed, or if someone accidentally takes your tablets, immediately seek advice from your doctor, pharmacist, or hospital.

Overdose symptoms may include a pounding heartbeat, increased pulse rate, and increased blood pressure.

If you forget to take Betmiga

If you forget to take your medicine, take the missed dose as soon as you remember. If there are less than 6 hours left for the next scheduled dose, skip the dose and continue taking the medicine at the usual time.

Do not take a double dose to make up for a forgotten dose. If you miss several doses, consult your doctor and follow his recommendations.
