Oxytrol (Oxybutynin) Dosage and Side Effects
OXYTROL is a transdermal system (skin patch) to treat overactive bladder.
Proper Use of this medication
If you apply more than the recommended dose of OXYTROL, contact your doctor or the nearest regional Poison Control Centre.
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). Oxybutynin therapy has also been associated with skin rash, painful urination, nausea, abdominal pain, back pain, and fatigue.
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.
These are not all the side effects of OXYTROL. For a complete list, ask your doctor or pharmacist.
