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 sclérose en plaques. 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:

• Si vous êtes enceinte ou si vous allaitez.

• Si vous avez une maladie cardiaque, telle qu'un rythme cardiaque inhabituel, des problèmes avec les vaisseaux sanguins de votre cœur, ou une insuffisance cardiaque.

• Si vous avez des problèmes avec le fonctionnement de votre foie ou de vos reins.

• Si vous avez des problèmes avec votre glande prostatique.

• If you have any of the following conditions: increased eye pressure (called glaucoma); hiatus hernia; an overactive thyroid gland; high blood pressure; a condition causing muscle weakness, called myasthenia gravis.

• If you have a condition which could cause a blockage in your stomach, bowel or urinary tract.

• If you have a rare inherited blood condition called porphyria.

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

• If you are taking any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.
  

• 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.

• Essayez de respecter vos rendez-vous réguliers avec votre médecin. Cela permet à votre médecin de suivre vos progrès et de revoir votre traitement.

• Les boissons contenant de la caféine (par exemple, thé, café, chocolat chaud et cola) peuvent aggraver vos symptômes. Cela est dû au fait que la caféine augmente le flux urinaire (c'est un diurétique naturel) et vous donnera envie d'uriner. Si vous consommez beaucoup de boissons contenant de la caféine, envisagez de passer à des alternatives décaféinées.

• 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 and go to the toilet, so you may want to avoid drinking too much during the evening.

• Votre médecin peut vous suggérer de faire des exercices du plancher pelvien pour renforcer les muscles autour de la partie inférieure de votre vessie. Ceux-ci peuvent aider 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.

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.

• Gardez tous les médicaments hors de la portée et de la vue des enfants.

• Conserver dans un endroit frais et sec, à l'abri de la chaleur et de la lumière directes.

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