OXYTROL is the first and only transdermal system (skin patch) to treat overactive bladder (OAB). OXYTROL's transdermal delivery system delivers oxybutynin, a medication widely accepted and prescribed in oral formulations for almost 30 years, into your bloodstream. Since the drug is delivered into your bloodstream through your skin, it bypasses the initial metabolism process in the liver and the stomach as seen with oral therapies. OXYTROL is a thin, flexible and clear patch that should be applied to the abdomen, hip or buttock twice weekly and provides continuous and consistent delivery of oxybutynin over a three to four day interval. Each patch is sealed in its own protective pouch. When you are ready to put on the OXYTROL patch, tear open the pouch and remove the patch. Apply the patch to your skin right away. Do not keep or store the patch outside the sealed pouch. OXYTROL can be worn during normal activities, including bathing, swimming, showering, or exercising.
You may see mild redness at the site when a patch is removed. This redness should disappear within several hours after removing the patch. If uncomfortable irritation or excessive itchiness continues, tell your doctor. Oxybutynin may cause sleepiness or blurred vision, so be careful when driving or operating machinery. In addition, sleepiness may be increased by drinking alcohol (beer, wine or hard liquor). Since oxybutynin treatment may decrease sweating, you may overheat or have fever or heat stroke if you are in warm or hot temperatures. The most common side effects of OXYTROL are skin reactions where the patch is put on. These include itching and redness. Other side effects include dry mouth, constipation, abnormal vision and headache. If you take other medicines that cause dry mouth, constipation, or sleepiness, OXYTROL can increase those effects.
