Oxybutynine

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 incontinence.

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 multiple sclerosis. 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.

Before taking oxybutynin

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:

• Si vous êtes enceinte ou si vous allaitez.

• Si vous souffrez d'une affection cardiaque, telle qu'un rythme cardiaque inhabituel, des problèmes au niveau des vaisseaux sanguins du cœur ou une insuffisance cardiaque.

• Si vous avez des problèmes de fonctionnement du foie ou des reins.

• Si vous avez des problèmes de prostate.

• Si vous souffrez de l'une des affections suivantes : augmentation de la pression oculaire (appelée glaucome) ; hernie hiatale ; hyperactivité de la glande thyroïde ; hypertension artérielle ; maladie entraînant une faiblesse musculaire, appelée myasthénie grave.

• Si vous souffrez d'une affection susceptible de provoquer un blocage de l'estomac, de l'intestin ou des voies urinaires.

• Si vous êtes atteint d'une maladie héréditaire rare du sang appelée porphyrie.

• Si vous avez déjà eu une réaction allergique à un médicament.

• Si vous prenez d'autres médicaments. Cela inclut tous les médicaments que vous prenez et qui sont disponibles sans ordonnance, ainsi que les médicaments à base de plantes et les médicaments complémentaires.
  

How to take oxybutynin tablets/medicine

• 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.

How to use oxybutynin patches

• 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.

Tirer le meilleur parti de votre traitement

• 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.

• Essayez de vous rendre à vos rendez-vous réguliers avec votre médecin. Il pourra ainsi vérifier vos progrès et revoir votre traitement.

• Les boissons contenant de la caféine (par exemple, le thé, le café, le chocolat chaud et le cola) peuvent aggraver vos symptômes. En effet, la caféine augmente le débit urinaire (c'est un diurétique naturel) et vous donne envie d'uriner. Si vous buvez beaucoup de boissons contenant de la caféine, envisagez de passer à des boissons décaféinées.

• Essayez de maintenir une vie normale autant que possible en ce qui concerne la consommation d'alcool et les visites aux toilettes. Cependant, si vous buvez tard dans la nuit, votre sommeil risque d'être perturbé par l'envie de vous lever et d'aller aux toilettes, c'est pourquoi il est préférable d'éviter de trop boire pendant la soirée.

• Votre médecin peut vous suggérer de faire des exercices du plancher pelvien pour renforcer les muscles situés sous la vessie. Ces exercices peuvent contribuer à améliorer vos symptômes.

• 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.
