Contents of the pack and other information
Betmiga contains the active substance mirabegron. It is a bladder muscle relaxant (a so called
beta 3-adrenoceptor agonist), which reduces the activity of an overactive bladder and treats the related symptoms.
Betmiga is used to treat the symptoms of an overactive bladder in adults such as:
suddenly needing to empty your bladder (called urgency)
having to empty your bladder more than usual (called increased urinary frequency)
not being able to control when to empty your bladder (called urgency incontinence)
if you are allergic to mirabegron or any of the other ingredients of this medicine (listed in section 6)
if you have very high uncontrolled blood pressure.
Talk to your doctor or pharmacist before taking Betmiga:
if you have trouble emptying your bladder or you have a weak urine stream or if you take other medicines for the treatment of overactive bladder such as anticholinergic medicines.
if you have kidney or liver problems. Your doctor may need to reduce your dose or may tell you not to take Betmiga, especially if you are taking other medicines such as itraconazole, ketoconazole (fungal infections), ritonavir (HIV/AIDS) or clarithromycin (bacterial infections). Tell your doctor about the medicines that you take.
if you have an ECG (heart tracing) abnormality known as QT prolongation or you are taking any medicine known to cause this such as:
medicines used for abnormal heart rhythm such as quinidine, sotalol, procainamide, ibutilide, flecainide, dofetilide, and amiodarone;
medicines used for allergic rhinitis;
antipsychotic medicines (medicines for mental illness) such as thioridazine, mesoridazine, haloperidol, and chlorpromazine;
anti-infectives such as pentamidine, moxifloxacin, erythromycin, and clarithromycin.
Mirabegron may cause your blood pressure to increase or make your blood pressure worse if you have a history of high blood pressure. It is recommended that your doctor check your blood pressure while you are taking Mirabegron.
Do not give this medicine to children and adolescents under the age of 18 years because the safety and efficacy of Betmiga in this age group has not been established.
Tell your doctor or pharmacist if you are taking, have recently used or might use any other medicines.
Betmiga may affect the way other medicines work, and other medicines may affect how this medicine works.
Tell your doctor if you use thioridazine (a medicine for mental illness), propafenone or flecainide (medicines for abnormal heart rhythm), imipramine or desipramine (medicines used for depression). These specific medicines may require dose adjustment by your doctor.
Tell your doctor if you use digoxin (a medicine for heart failure or abnormal heart rhythm).
Blood levels of this medicine are measured by your doctor. If the blood level is out of range, your doctor may adjust the dose of digoxin.
Tell your doctor if you use dabigatran etexilate (a medicine which is used to reduce the risk of brain or body vessel obstruction by blood clot formation in adult patients with an abnormal heart beat (atrial fibrillation) and additional risk factors). This medicine may require dose adjustment by your doctor.
If you are pregnant, think you may be pregnant or are planning to have a baby you should not take Betmiga.
If you are breast-feeding, ask your doctor or pharmacist for advice before taking this medicine. It is likely that this medicine passes into your breast milk. You and your doctor should decide if you should take Betmiga or breastfeed. You should not do both.
There is no information to suggest that this medicine affects your ability to drive or use machines.
Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.
The recommended dose is one 50 mg tablet by mouth once daily. If you have kidney or liver problems, your doctor may need to reduce your dose to one 25 mg tablet by mouth once daily. You should take this medicine with liquids and swallow the tablet whole. Do not crush or chew the tablet. Betmiga can be taken with or without food.
If you have taken more tablets than you have been told to take, or if someone else accidentally takes your tablets, contact your doctor, pharmacist or hospital for advice immediately.
Symptoms of overdose may include a forceful beating of the heart, an increased pulse rate or an increased blood pressure.
If you forget to take your medicine, take the missed dose as soon as you remember. If it is less than
6 hours before your next scheduled dose, skip the dose and continue to take your medicine at the usual time.
Do not take a double dose to make up for a forgotten dose. If you miss several doses, tell your doctor and follow the advice given to you.
Do not stop treatment with Betmiga early if you do not see an immediate effect. Your bladder might need some time to adapt. You should continue taking your tablets. Do not stop taking them when your bladder condition improves. Stopping treatment may result in recurrence of symptoms of overactive bladder.
Do not stop taking Betmiga without talking to your doctor first, as your overactive bladder symptoms may come back.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
