Oxybutynin is used to treat symptoms of overactive bladder, such as frequent or urgent urination and incontinence (urine leakage).

Oxybutynin is also used in children at least 6 years old with overactive bladder related to a neurologic condition such as spina bifida.

Oxybutynin may also be used for purposes not listed in this medication guide.

You should not use oxybutynin if you are allergic to it, or if you have:

• untreated or uncontrolled narrow-angle glaucoma;
• a blockage in your digestive tract (stomach or intestines); or
• if you are unable to urinate.

Tell your doctor if you have ever had:

• glaucoma;
• trouble urinating;
• ulcerative colitis;
• Parkinson's disease;
• dementia;
• a nerve disorder that affects your heart rate, blood pressure, or digestion;
• myasthenia gravis; or
• a stomach disorder such as gastroesophageal reflux disease (GERD) or slow digestion.

Tell your doctor if you are pregnant or breastfeeding.

Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.

Take oxybutynin with a full glass of water, at the same time each day.

You may take oxybutynin with or without food.

Swallow the extended-release tablet whole and do not crush, chew, or break it.

Measure liquid medicine with the supplied measuring device (not a kitchen spoon).

Part of a tablet shell may appear in your stool but this will not make the medicine less effective.

Store at room temperature away from moisture and heat.

Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

Avoid driving or hazardous activity until you know how this medicine will affect you. Your reactions could be impaired.

Avoid becoming overheated or dehydrated during exercise and in hot weather. Oxybutynin can decrease sweating and you may be more prone to heat stroke.

Drinking alcohol with this medicine can increase side effects.

Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Stop using oxybutynin and call your doctor at once if you have:

• diarrhea, constipation.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Using oxybutynin with other drugs that make you drowsy can worsen this effect. Ask your doctor before using opioid medication, a sleeping pill, a muscle relaxer, or medicine for anxiety or seizures.

• antibiotic, antifungal, or antiviral medicine;
• bronchodilator asthma medication;
• cold or allergy medicine (Benadryl and others);
• medicine to treat overactive bladder;
• medicine to treat dementia;
• medicine to treat Parkinson's disease; or
• medicine to treat stomach problems, motion sickness, or irritable bowel syndrome.
