Modified-release tablets

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

Urinary urgency 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 exercícios do assoalho pélvico) 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:

  • Se você está grávida, tentando ter um bebê ou amamentando.

  • If you have an unusual heart rhythm.

  • Se você tem pressão 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.

  • Se você já teve uma reação alérgica a um medicamento.

  • Se você estiver tomando outros medicamentos. Isso inclui quaisquer medicamentos que você esteja tomando e que estejam disponíveis para compra sem receita médica, bem como medicamentos fitoterápicos e complementares.

  • 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.

  • Bebidas contendo cafeína (por exemplo, chá, café, chocolate quente e refrigerante) podem piorar seus sintomas. Isso porque a cafeína é um diurético natural e fará você querer urinar. Se você consumir muitas bebidas com cafeína, considere trocar por alternativas descafeinadas.

  • 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.
