oxybutynin

Package leaflet: Information for the user


Kentera 3.9 mg / 24 hours transdermal patch

oxybutynin


Read all of this leaflet carefully before you start using this medicine because it contains important information for you.


Since treatment with oxybutynin may cause decreased perspiration, there is an increased risk of fever and heat stroke if you are exposed to high environmental temperatures.

Children and adolescents

Kentera is not recommended for use in children or adolescents.


Other medicines and Kentera

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.


Applying the Kentera patch at the same time as taking other medicines that have similar side effects such as dry mouth, constipation and drowsiness, may increase how often and how severe these side effects are experienced.


Oxybutynin may slow the digestive tract and thereby influence the adsorption of other oral medicines, or the use of this medicine together with other medicines may increase the effect of oxybutynin, especially:


Kentera with alcohol

Oxybutynin may cause drowsiness or blurred vision. Drowsiness may be increased by consumption of alcohol.


Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.


Kentera should not be used during pregnancy unless clearly necessary.


When oxybutynin is used during breast-feeding, a small amount is excreted in the mother’s milk. Use of oxybutynin while breast-feeding is therefore not recommended.


Driving and using machines

Because Kentera may produce drowsiness, somnolence, or blurred vision, patients should be advised to exercise caution when driving or using machinery.


  1. How to use Kentera


    Always use this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.


    Apply a new Kentera patch twice weekly (every 3 to 4 days) according to the instructions for use. Change the patch on the same two days every week, for example, every Sunday and Wednesday or Monday and Thursday.

    Printed on the inside flap of your Kentera package, you will find a Kentera calendar checklist that will help you to remember your dosing schedule. Mark the schedule you plan to follow and remember always to change your patch on the same two days of the week you have chosen on your calendar.

    Make sure to wear only one patch at a time and wear your patch continuously, until it is time to apply a new one.

    Where to apply

    Apply the patch to a clean, dry, smooth area of skin on your abdomen, hips or buttocks. Avoid placing the patch in the waistline area to prevent tight clothing from rubbing against the patch. Do not expose the patch to the sun. Place the patch underneath your clothing. Rotate application sites with each new application. Do not apply a patch to the same place on your body for at least 1 week.

    How to apply

    Each patch is individually sealed in a protective sachet. Please read all the information below before you begin to apply Kentera.


    To apply Kentera


    Step 1: Choose a spot for the patch that is:


    • Freshly washed, but dry and cool (wait a few minutes after taking a hot bath or shower).

    • Free of body powder, lotion, and oil.

    • Free of cuts, rashes or any other skin irritation.


      Step 2: Open the sachet that contains the patch.


    • Tear open along arrows marked on the right side of the sachet as shown in drawing below.

    • Do not cut the sachet with scissors, which might damage the patch inside.

    • Pull the patch out.

    • Apply immediately to your skin; do not keep or store the patch outside the sealed sachet.

      Step 3: Apply one half of the patch to your skin.


    • Gently bend the patch and remove the first piece of protective liner, which covers the sticky surface of the patch.

    • Without touching the sticky surface, firmly press the patch, adhesive face down, onto the part of the abdomen, hips or buttocks you have selected for application.

      Step 4: Apply the second half of the patch to your skin.


    • Bend the patch back over itself. Press down on the liner firmly.

    • Push the liner forward a little to loosen the edge.

    • Grab the loose edge at either corner and peel off the second piece of the liner. Try not to touch the sticky surface of the patch.

    • Press the entire patch firmly onto the skin with your fingertips. Press for at least 10 seconds to make sure the patch will stay in place. Be sure all of it sticks to your skin, even around the edges.

    • Discard the protective liners.

      Bathing, showering, swimming and exercise

      You should wear each patch all the time until you apply a new one. Baths, showers, swimming and exercise should not affect the patch as long as you don’t rub the patch as you wash. Avoid soaking in a hot bath for a long period of time, which can make the patch come off.


      If the patch comes off

      If the patch starts to lift off your skin, apply a little bit of pressure using your fingertips. The patch is designed to re-stick. Very rarely will the patch come off completely. If it does, try putting the same patch back on the same spot. If it sticks firmly all over, leave it on. If not, take it off and put a new patch on a new spot. No matter what day this happens, continue with the twice-a-week schedule that you have marked on your patch box.


      If you forget to change the patch after 3-4 days

      As soon as you remember, remove the old patch and apply a new one to a new spot on your abdomen, hips or buttocks. No matter what day this happens, continue with the same twice-a-week schedule for your next patch, even if it means changing the new patch before 3 to 4 days have elapsed.


      How to remove


      When changing the patch, remove the old patch slowly. Fold it in half (sticky sides together) and throw it away to keep out of the reach of children and pets. Mild redness may be present at the application site. This redness should disappear within several hours after removal of the patch. If irritation persists, please contact your doctor.


      Gently washing the application site with warm water and a mild soap should remove any adhesive that remains on your skin after removal of the patch. A small amount of baby oil may also be used to remove any excess residue. Rings of adhesive that become soiled may require a medical adhesive removal pad that should be available from your pharmacist. Alcohol or other strong solvents may cause skin irritation and should not be used.


      After use the patch still contains substantial quantities of active ingredients. Remaining active ingredients of the patch may have harmful effects if reaching the aquatic environment. Hence, after removal, the used patch should be folded in half, adhesive side inwards so that the release membrane is not exposed, placed in the original sachet and then discarded safely out of reach of children. Any used or unused patches should be discarded according to local requirements or returned to the pharmacy. Used patches should not be flushed down the toilet nor placed in liquid waste disposal systems.

      If you use more Kentera than you should

      Do not apply more than one patch at a time.


      If you forget to use Kentera

      Apply a Kentera patch as soon as you realise your patch is missing, or you have missed a scheduled day of application.


      If you stop using Kentera

      Your urge incontinence may return and you may have increased urinary frequency if you decide to stop using the patch. Continue to use Kentera as long as your doctor tells you to.


      If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
