Modified-release tablets

Mirabegron is given to treat urinary symptoms such as urgency, frequency and incontinencia.

Urgencia urinaria occurs when you get a sudden and urgent need to pass urine. If you leak urine before you go to the toilet, this is called incontinence. If you need to take more trips to the toilet than normal, this is called urinary frequency. Mirabegron helps to decrease the feeling of urgency, the number of urine leakages, and the number of trips to the toilet. It is usually prescribed when other treatments (such as pelvic floor exercises) have not worked and if other, more commonly used medicines are not suitable.

Mirabegron works by relaxing the muscles around your bladder. This increases the volume of urine that your bladder can hold, and reduces your need to pass urine as frequently or as urgently.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking mirabegron it is important that your doctor knows:

  • Si estás embarazada, intentando concebir o amamantando.

  • Si tienes un ritmo cardíaco inusual.

  • Si tienes presión arterial alta.

  • If you have any problems with the way your liver works or any problems with the way your kidneys work.

  • If you have a bladder obstruction.

  • Si alguna vez has tenido una reacción alérgica a un medicamento.

  • Si está tomando otros medicamentos. Esto incluye cualquier medicamento que esté tomando y que esté disponible para comprar sin receta, así como medicamentos herbales y complementarios.

  • Before you start taking the tablets, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about mirabegron and will provide you with a full list of the side-effects which you may experience from taking it.

  • Take mirabegron exactly as your doctor tells you to. It is usual to take one 50 mg tablet daily. The tablet will slowly release the medicine into your body. If you have any problems with your liver or kidneys, you will be prescribed a lower strength of tablet (25 mg) to take.

  • You can generally take mirabegron at whatever time of day you find easiest to remember, but try to take your doses at the same time of day, each day. This will help you to avoid missing doses.

  • Swallow the tablet with a drink of water. Swallow it whole - do not break or crush the tablet, as this will affect the way the medicine is released into your body. You can take mirabegron before or after meals.

  • If you forget to take a dose, take it as soon as you remember. If you do not remember until the following day, skip the forgotten dose. Do not take two doses together to make up for a missed dose.

  • Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress and review your treatment. Your doctor may want to check your blood pressure regularly as this can be increased in some people taking mirabegron.

  • Drinks containing caffeine (for example, tea, coffee, hot chocolate and cola) may make your symptoms worse. This is because caffeine is a natural diuretic and will make you want to pass urine. If you drink a lot of caffeine-containing fluids, consider switching to decaffeinated alternatives.

  • Try to maintain a normal life as much as possible with regard to drinking and visiting the toilet. However, drinking late at night may mean your sleep is disturbed by the desire to get up to go to the toilet, so you may want to avoid drinking too much during the evening.

Preguntas frecuentes

How does mirabegron work to improve my urinary symptoms?

Mirabegron relaxes the muscles surrounding your bladder. This action allows your bladder to hold a larger volume of urine, which in turn reduces the urgent and frequent need to pass urine, and helps with incontinence episodes.

Are there other treatments for urinary symptoms before mirabegron?

Yes, mirabegron is usually prescribed after other treatments, such as pelvic floor exercises, have not been effective, or if other more commonly used medications are not suitable for you.

What should I do if I forget to take a dose of mirabegron?

If you forget a dose, take it as soon as you remember. However, if you don't remember until the next day, you should skip the missed dose. Never take two doses at once to compensate for a forgotten dose.

Can I drink tea or coffee while taking mirabegron?

Drinks containing caffeine, such as tea, coffee, hot chocolate, and cola, can make urinary symptoms worse because caffeine acts as a natural diuretic. If you consume a lot of these drinks, consider switching to decaffeinated versions.

Will taking mirabegron affect my blood pressure?

Your doctor may want to monitor your blood pressure regularly while you are taking mirabegron, as it can be increased in some people. This is part of the regular check-ups your doctor will conduct to review your treatment progress.

Can I take mirabegron if I have an unusual heart rhythm or high blood pressure?

It is important to inform your doctor if you have an unusual heart rhythm or high blood pressure, as these conditions are relevant to whether mirabegron is suitable for you or if extra care is needed during your treatment.

What should I do if I experience a urine infection while taking mirabegron?

If you suspect you have a urine infection, you should speak with your doctor. Urine infections can be easily treated.
