Oxibutinina

About oxybutynin

Oxybutynin is prescribed to treat urinary symptoms such as urgency, frequency and incontinence. Urinary urgency occurs when you have a sudden and urgent need to pass urine. If you need to take more trips to the toilet than normal, this is called urinary frequency. If you leak urine before you go to the toilet, this is called incontinência.

There are several different causes of these urinary symptoms, such as weakened pelvic floor muscles, problems causing your bladder muscles to contract too much or too early and medical conditions such as esclerose múltipla. Sometimes the cause of these symptoms is unknown.

In addition to these uses, oxybutynin can also be prescribed for older children (over 5 years of age) to help reduce bedwetting caused by an overactive bladder.

Oxybutynin works by relaxing the muscles of the bladder and stopping sudden muscle contractions. It also increases the volume of urine that the bladder can hold. These actions help to control the release of urine and ease your symptoms.

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 oxybutynin it is important that your doctor knows:

• Se você está grávida ou amamentando.

• Se você tem uma condição cardíaca, como um ritmo cardíaco incomum, problemas com os vasos sanguíneos do seu coração ou insuficiência cardíaca.

• Se você tiver algum problema com o funcionamento do seu fígado ou com o funcionamento dos seus rins.

• Se você tiver algum problema com sua glândula prostática.

• Se você tiver alguma das seguintes condições: aumento da pressão ocular (chamado glaucoma); hérnia de hiato; uma glândula tireoide hiperativa; pressão arterial alta; uma condição que causa fraqueza muscular, chamada miastenia gravis.

• Se você tiver uma condição que possa causar uma obstrução no estômago, intestino ou trato urinário.

• Se você tem uma condição rara de sangue hereditária chamada porfiria.

• 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.
  

• Take oxybutynin exactly as your doctor tells you to. Your dose will be printed on the label of the pack to remind you about what the doctor said to you but if you are unsure about what to do, please ask your pharmacist to explain it to you again. You can take oxybutynin either before or after meals.

• There are several strengths of standard-release tablet available: 2.5 mg, 3 mg and 5 mg. An oral liquid medicine is available for children and people who have difficulty swallowing tablets. If you have been prescribed standard-release tablets or oral liquid medicine, you will be asked to take one dose two or three times a day to begin with. Your doctor may increase your dose as you go on, depending upon how you respond. If the tablets/medicine have been prescribed for your child to reduce bedwetting, it is best if they take the last dose just before they go to bed.

• If you have been prescribed the prolonged-release tablets (brand name Lyrinel® XL) you will be asked to take one tablet every day to begin with, although your doctor may increase your dose as you go on. These tablets have been specially made to release oxybutynin evenly over the day, so it is important that you swallow the tablet whole - do not chew or crush it before you swallow.

• Try to take your doses at the same times of day each day, as this will help you to remember to take them regularly. If you do forget to take a dose, take it as soon as you remember, unless it is nearly time for your next dose, in which case leave out the missed dose. Do not take two doses together to make up for a forgotten dose.

• If you have been prescribed oxybutynin patches (brand name Kentera®), you should apply one patch twice-weekly.

• Apply a patch to a clean, dry area of skin on your tummy (abdomen), hip or bottom. Leave the patch in place for three or four days and then remove it before applying another patch. Apply the new patch to a different area of skin (on your abdomen, hip or bottom). Leave the second patch in place for the rest of the week and then start the next week with a new patch again.

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

• Tente manter suas consultas regulares com seu médico. Isso é para que seu médico possa verificar seu progresso e revisar seu tratamento.

• Bebidas que contêm cafeína (por exemplo, chá, café, chocolate quente e refrigerante de cola) podem piorar seus sintomas. Isso ocorre porque a cafeína aumenta o fluxo urinário (é um diurético natural) e fará com que você queira urinar. Se você consome muitas bebidas com cafeína, considere mudar para alternativas descafeinadas.

• Tente manter uma vida normal tanto quanto possível em relação a beber e visitar o banheiro. No entanto, beber tarde da noite pode significar que seu sono seja interrompido pelo desejo de se levantar e ir ao banheiro, então você pode querer evitar beber muito durante a noite.

• Seu médico pode sugerir que você faça alguns exercícios para o assoalho pélvico para fortalecer os músculos ao redor da parte inferior da sua bexiga. Estes podem ajudar a melhorar seus sintomas.

• If you buy any medicines or herbal remedies, always check with a pharmacist that they are suitable to take with oxybutynin. Some medicines (particularly antihistamines) can increase the chance that you will experience unwanted effects such as a dry mouth, constipation and feeling sleepy.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the common ones associated with oxybutynin. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

If you experience any other symptoms which you think may be due to oxybutynin, please speak with your doctor or pharmacist for further advice.

• Mantenha todos os medicamentos fora do alcance e da vista das crianças.

• Armazene em local fresco e seco, longe de calor e luz diretos.

• Remember to check the expiry date on the pack. The liquid medicine keeps for one month after the bottle has been opened.
