1. What Betmiga is and what it is used for
Betmiga contains the active substance mirabegron. It is a relaxant of the bladder muscle (a so-called beta 3-adrenergic receptor agonist), which reduces the activity of an overactive bladder, treats the associated symptoms, and reduces neurogenic detrusor overactivity.
Betmiga is used for:
- the treatment of symptoms of a condition called overactive bladder in adults. These symptoms include: sudden need to empty the bladder (urgency); need to empty the bladder more frequently than normal (increased urinary frequency); inability to control bladder emptying (urge incontinence).
- the treatment of a condition called neurogenic detrusor overactivity in children aged 3 to less than 18 years. Neurogenic detrusor overactivity is a condition in which involuntary contractions of the bladder occur due to a congenital condition or nerve damage affecting bladder control. If left untreated, neurogenic detrusor overactivity may cause damage to the bladder and/or kidneys. Betmiga is used to increase the amount of urine that can be stored in the bladder and to reduce urine leakage.
2. What you should know before taking Betmiga
Do not take Betmiga
- if you are allergic to mirabegron or to any of the other ingredients of this medicine (listed in section 6);
- if you have uncontrolled, severely high blood pressure.
Warnings and precautions
Talk to your doctor or pharmacist before taking Betmiga
- if you have difficulty emptying your bladder or have a weak urine flow, or if you are taking other medicines for overactive bladder or neurogenic detrusor overactivity, such as antimuscarinic drugs.
- if you have kidney or liver problems. Your doctor may need to reduce your dose or may advise you not to take Betmiga, especially if you are taking other medicines such as itraconazole, ketoconazole (for fungal infections), ritonavir (for HIV/AIDS), or clarithromycin (for bacterial infections). Inform your doctor if you are taking any other medicines.
- if you have an abnormality on your ECG (electrocardiogram) known as QT prolongation, or if you are taking a medicine known to cause this abnormality, such as: medicines used to treat heart rhythm disorders, such as quinidine, sotalol, procainamide, ibutilide, flecainide, dofetilide, and amiodarone; medicines used to treat allergic rhinitis; antipsychotics (medicines used to treat mental illnesses), such as thioridazine, mesoridazine, haloperidol, and chlorpromazine; anti-infectives, such as pentamidine, moxifloxacin, erythromycin, and clarithromycin. If you have a history of high blood pressure, Betmiga may increase or worsen your blood pressure. Your doctor is advised to monitor your blood pressure while you are taking this medicine.
Children and adolescents
Do not give this medicine to children and adolescents under 18 years of age for the treatment of overactive bladder, as the safety and efficacy of Betmiga in this population have not been established. Betmiga must not be used in children under 3 years of age for the treatment of neurogenic detrusor overactivity.
Other medicines and Betmiga
Inform your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. Betmiga may affect the action of other medicines, and other medicines may affect how this medicine works.
- Inform your doctor if you are taking thioridazine (a medicine used to treat mental illnesses), propafenone or flecainide (medicines used to treat heart rhythm disorders), imipramine or desipramine (medicines used to treat depression). These specific medicines may require your doctor to adjust the dose.
- Inform your doctor if you are taking digoxin (a medicine used to treat heart failure or heart rhythm disorders). Your doctor will monitor the blood levels of this medicine. If blood levels are outside the normal range, your doctor may adjust the dose of digoxin.
- Inform your doctor if you are taking dabigatran etexilate (a medicine used to reduce the risk of blood vessel blockage in the brain or body caused by blood clots in patients with heart rhythm disorders (atrial fibrillation) and additional risk factors). This medicine may require a dose adjustment by your doctor.
Pregnancy and breastfeeding
If you are pregnant, think you might be pregnant, or are planning to become pregnant, do not take Betmiga.
If you are breastfeeding, ask your doctor or pharmacist for advice before taking this medicine. This medicine may pass into breast milk. Together with your doctor, you will need to decide whether to take Betmiga or breastfeed. You should not do both.
Driving and using machines
There are no data indicating that this medicine impairs the ability to drive or use machinery.
3. How to take Betmiga
Take this medicine exactly as instructed by your doctor. If you have any doubts, consult your doctor or pharmacist.
Use in adults with overactive bladder
The recommended dose is one 50 mg tablet taken orally once daily. If you have kidney or liver problems, your doctor may need to reduce your dose to one 25 mg tablet taken orally once daily. Take this medicine with liquid and swallow the tablet whole. Do not break or chew the tablet. Betmiga can be taken with or without food.
Use in children and adolescents (aged 3 to less than 18 years) with neurogenic detrusor overactivity
Take this medicine orally once daily. You must take this medicine with liquid and swallow the tablet whole. Do not break or chew the tablet. Betmiga must be taken with food. Your doctor will tell you what dose to take/what dose your child should take. The doctor will calculate the correct dose for a patient based on body weight. You must follow the doctor's instructions exactly.
If you take more Betmiga than you should
If you have taken more tablets than prescribed, or if someone else has accidentally taken your tablets, contact your doctor, pharmacist, or hospital immediately.
Symptoms of overdose may include increased heart rate, increased pulse, or increased blood pressure.
If you forget to take Betmiga
If you forget to take a dose, take it as soon as you remember, unless there are 12 hours or less before your next dose. Then continue taking the medicine at your usual time.
Do not take a double dose to make up for a forgotten dose. If you forget to take several doses, contact your doctor and follow their advice.
If you stop taking Betmiga
Do not stop treatment with Betmiga prematurely if you do not see an immediate effect. Your bladder may need some time to adjust. Continue taking the tablets. Do not stop treatment when your bladder condition improves. Stopping treatment may cause symptoms of overactive bladder syndrome or neurogenic detrusor overactivity to return.
Do not stop treatment with Betmiga without first talking to your doctor, as symptoms of overactive bladder syndrome or neurogenic detrusor overactivity may recur.
If you have any questions about the use of this medicine, consult your doctor or pharmacist.
