What is oxybutynin?
Oxybutynin reduces muscle spasms of the bladder and urinary tract.
Oxybutynin topical (for the skin) is used to treat symptoms of overactive bladder such as frequent or urgent urination, and incontinence (urine leakage).
Oxybutynin topical may also be used for purposes not listed in this medication guide.
You should not use oxybutynin topical if you have uncontrolled narrow-angle glaucoma, a blockage in your stomach or intestines, or if you are unable to urinate.
Before taking this medicine
You should not use this medicine if you are allergic to oxybutynin, or if you have:
untreated or uncontrolled narrow-angle glaucoma;
a blockage in your digestive tract (stomach or intestines); or
if you have decreased urination or are unable to urinate.
To make sure oxybutynin topical is safe for you, tell your doctor if you have:
liver or kidney disease;
an intestinal disorder, such as ulcerative colitis;
if you have trouble emptying your bladder.
Oxybutynin topical is not expected to harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant.

How should I use oxybutynin?
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.
Oxybutynin topical can be applied to the skin on your stomach, upper arm, shoulder, or thigh. Apply the gel to a different place on any of these skin areas each time you use it. Do not apply the gel to the same skin two days in a row.
Wash your hands with soap and water before and after applying this medication. Also wash the skin area to be treated, using a mild soap or cleanser. Allow the skin to dry completely before applying oxybutynin topical.
Tear open the sealed Gelnique packet and empty the entire contents into your hand. You may also empty the packet directly onto the treatment area. Each packet of Gelnique is for one use only. Throw away the empty packet in a place where children and pets cannot get to it.
To get the correct amount of Anturol gel for one application, press the pump down 3 times. You may pump the gel directly onto the treatment area.
Do not apply the gel to recently shaved skin, open wounds, scars, tattoos, or irritated or broken skin. Do not apply to the breasts or genital areas.
Do not bathe, shower, swim, use a hot tub, or exercise vigorously for at least 1 hour after applying this medication.
It is best to cover treated skin areas with clothing after the gel has dried completely. This will help prevent getting this medicine on your other skin or on other people. If someone else does come into contact with a treated skin area, they should wash the contact area right away with soap and water.
Oxybutynin gel is flammable. Avoid using near open flame, and do not smoke until the gel has completely dried on your skin.
Store at room temperature away from moisture and heat.
What happens if I miss a dose?
Apply the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
What should I avoid while using oxybutynin?
Avoid getting this medicine in your eyes, nose, or mouth. If this does happen, rinse with water.
Avoid applying lotions, powders, or oils to the skin you plan to treat with oxybutynin topical. These other skin products can make it harder for your skin to absorb oxybutynin, and it may not work as well. You may apply oxybutynin gel to skin that has been treated with sunscreen.
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.
Drinking alcohol can increase certain side effects of oxybutynin.
Avoid becoming overheated or dehydrated during exercise and in hot weather. Oxybutynin can decrease sweating and you may be more prone to heat stroke.
