Common uses

Oxybutynin reduces muscle spasms of the bladder and urinary tract.
Oxytrol is used to treat symptoms of overactive bladder, such as frequent or urgent urination, incontinence (urine leakage), and increased nighttime urination.
Oxytrol may also be used for purposes other than those listed in this medication guide.

Do not use Oxytrol if you are allergic to oxybutynin, or if you have:
• untreated or uncontrolled glaucoma;

Directions

Use this medication exactly as it was prescribed for you. Do not use the medication in larger amounts, or use it for longer than recommended by your doctor. Follow the instructions on your prescription label.
Oxytrol comes with patient instructions for safe and effective use. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.

Cautions

Do not use Oxytrol if you are allergic to oxybutynin, or if you have uncontrolled glaucoma, a blockage in your stomach or intestines, or if you are unable to urinate. Oxybutynin can cause blurred vision, drowsiness, or dizziness. Be careful if you drive or do anything that requires you to be alert and able to see clearly. Avoid drinking alcohol. It can increase some of the side effects of oxybutynin.
Avoid becoming overheated or dehydrated during exercise and in hot weather. Drink plenty of fluids to keep yourself hydrated while you are using oxybutynin.
Do not expose the Oxytrol patch to sunlight. It should be worn under clothing.

Possible side effects

Get emergency medical help if you have any of these signs of an allergic reaction: hives; difficulty breathing; swelling of your face, lips, tongue, or throat. Stop using Oxytrol and call your doctor at once if you have any of these serious side effects:
• fever with hot, dry skin;
• uneven heart rate;
• pain, burning, or other difficulty when urinating; or
• severe itching, burning, or blistering that does not clear up within several hours after removing the skin patch.
Continue using Oxytrol and talk to your doctor if you have any of these less serious side effects:
• mild skin itching, burning, redness, or discoloration where a patch was worn;
• dizziness, drowsiness, weakness;
• blurred vision;
• dry mouth;
• warmth, tingling, or redness under your skin;
• nausea, vomiting, stomach pain;
• constipation or diarrhea;
• dry eyes;
• stuffy nose;
• back pain;
• feeling restless; or
• sleep problems (insomnia).
Side effects other than those listed here may also occur. Talk to your doctor about any side effect that seems unusual or that is especially bothersome.
