What is Gelnique?

Gelnique (oxybutynin) reduces muscle spasms of the bladder and urinary tract.

Gelnique is a quick-drying, colorless topical gel used to treat symptoms of overactive bladder, such as frequent or urgent urination and incontinence (urine leakage).

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

Important information about Gelnique

Do not use Gelnique if you are allergic to oxybutynin, or if you have uncontrolled narrow-angle glaucoma, a blockage in your digestive tract, if you have decreased urination, or if you are unable to urinate.

Before using Gelnique, tell your doctor if you have urination problems, glaucoma, liver or kidney disease, myasthenia gravis, severe constipation, ulcerative colitis or other intestinal disorder, gastroesophageal reflux disease (GERD), or slow digestion.

Do not bathe, shower, swim, use a hot tub, or exercise vigorously for at least 1 hour after applying Gelnique gel.

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.

Gelnique gel is flammable. Avoid using near open flame, and do not smoke until the gel has completely dried on your skin. 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 Gelnique.

FDA pregnancy category B. Gelnique is not expected to be harmful to an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment.

How should I use Gelnique?

Use Gelnique 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.

Gelnique comes with patient instructions for safe and effective use. Follow these directions carefully. Ask your doctor or pharmacist if you have any questions.

Wash your hands with soap and water before and after applying this medication. Also wash the skin area to be treated. Use a mild soap or cleanser.

Each packet of Gelnique gel is for one use only. Throw away the empty packet in a place where children and pets cannot get to it.

Tear open the sealed packet and empty the entire contents into your hand. You may also empty the packet directly onto the treatment area. Gelnique can be applied to the skin on your stomach, upper arm, shoulder, or thigh.

Apply Gelnique 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.

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 Gelnique 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.

Gelnique gel is flammable. Avoid using near open flame, and do not smoke until the gel has completely dried on your skin. Keep Gelnique gel in its sealed packet until you are ready to use it. Store the packets at room temperature away from heat and moisture.

What happens if I miss a dose?

Apply the missed dose as soon as you remember. If it is almost time for your next dose, wait until then to use the medicine and skip the missed dose. Do not use extra medicine to make up the missed dose.

What happens if I overdose?

Seek emergency medical attention if you think you have used too much of this medicine.

Overdose symptoms may include feeling restless or excited, warmth or tingly feeling, fever, thirst, hot and dry skin, uneven heart rate, vomiting, and urinating less than usual or not at all.

What should I avoid while using Gelnique?

Avoid applying lotions, powders, oils to the skin you plan to treat with Gelnique. These other skin products can make it harder for your skin to absorb oxybutynin, and it may not work as well. You may apply Gelnique gel to skin that has been treated with sunscreen.

Avoid getting this medication in your mouth, nose, or eyes. If it does get into any of these areas, rinse with water. Do not apply Gelnique gel to recently shaved skin, open wounds, or irritated or broken skin. 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.
