Treatments > Medications Used In MS

Brand Name Chemical Name

Oxytrol (Oxybutynin Transdermal System)

Oxybutynin
(ox-i-byoo-ti-nin)

Primary Usage in MS

Generic Available
Bladder Dysfunction No

Description
Oxybutynin is an antispasmodic that helps decrease muscle spasms of the bladder and the frequent urge to urinate caused by these spasms. Oxytrol is a skin patch that delivers the active ingredient, oxybutynin, through your skin and into your bloodstream.

Proper Usage
A new patch is applied two times per week (every 3-4 days), with each patch worn until it is time to replace it with the next one. Only one patch is worn at a time.

The patch is placed on clean, dry, and smooth area of the abdomen, hips, or buttocks.

The patch should not be put at the waistline, where it will be rubbed by tight clothing, or on areas of skin that have been treated with creams or oils that will prevent the patch from sticking.

Precautions
This medication adds to the effects of alcohol and other central nervous system depressants (such as antihistamines, sedatives, tranquilizers, prescription pain medications, seizure medications, muscle relaxants). Be sure that your physician knows if you are taking these or any other medications.

This medication may cause your eyes to become more sensitive to light.

Oxybutynin may cause drying of the mouth. Since continuing dryness of the mouth can increase the risk of dental disease, alert your dentist if you are taking oxybutynin.

Oxybutynin has not been studied in pregnant women. It has not been shown to cause birth defects or other problems in animal studies. Any woman who wishes to become pregnant while using this medication should discuss it with her physician.

It is not known whether oxybutynin is excreted in breast milk. Since it tends to decrease body secretions, oxybutynin may reduce the flow of breast milk. Any woman who wishes to breastfeed while using this medication should discuss it with her physician.

Possible Side Effects
Side effects that typically go away as your body adjusts to the medication and do not require medical attention unless they continue for a few weeks or are bothersome: constipation*; decreased sweating; unusual drowsiness*; dryness of mouth, nose, throat; blurred vision*; decreased flow of breast milk; decreased sexual ability*; difficulty swallowing*; headache; increased light sensitivity; nausea or vomiting; trouble sleeping; unusual tiredness or weakness*.

Less common side effects that should be reported to your physician immediately: difficulty in urination*.

*Since it may be difficult to distinguish between certain common symptoms of MS and some side effects of oxybutynin, be sure to consult your healthcare professionals if an abrupt change of this type occurs.
