Use In Patients With Gastrointestinal Disorders
GELNIQUE, like other anticholinergic drugs, may decrease gastrointestinal motility and should be used with caution in patients with conditions such as ulcerative colitis or intestinal atony. GELNIQUE should be used with caution in patients who have gastroesophageal reflux and/or who are concurrently taking drugs (such as bisphosphonates) that can cause or exacerbate esophagitis.
Angioedema requiring hospitalization and emergency medical treatment has occurred with the first or subsequent doses of oral oxybutynin. In the event of angioedema, oxybutynincontaining product should be discontinued and appropriate therapy promptly provided.
In a controlled clinical trial of skin sensitization, 1 of 200 patients (0.5%) demonstrated skin hypersensitivity to GELNIQUE. Patients who develop skin hypersensitivity to GELNIQUE should discontinue drug treatment.
Central Nervous System Effects
GELNIQUE is associated with anticholinergic central nervous system (CNS) effects. A variety of CNS anticholinergic effects have been reported, including headache, dizziness, somnolence, confusion and hallucinations. Patients should be monitored for signs of anticholinergic CNS effects, particularly after beginning treatment. Advise patients not to drive or operate heavy machinery until they know how GELNIQUE affects them. If a patient experiences anticholinergic CNS effects, drug discontinuation should be considered.
Transfer of oxybutynin to another person can occur when vigorous skin-to-skin contact is made with the application site. To minimize the potential transfer of oxybutynin from GELNIQUE-treated skin to another person, patients should cover the application site with clothing after the gel has dried if direct skin-to-skin contact at the application site is anticipated [see CLINICAL PHARMACOLOGY]. Patients should wash their hands immediately after application of GELNIQUE.
GELNIQUE is an alcohol-based gel and is therefore flammable. Avoid open fire or smoking until gel has dried.

Instructions For Use
GELNIQUE is for topical application only and should not be ingested.
GELNIQUE should not be applied to recently shaved skin surfaces. Patients should wash hands immediately after product application. Application sites should not be subject to showering or water immersion for 1 hour after product application. Application sites should be covered with clothing if close skin-to-skin contact at the application site is anticipated.
Alcohol based gels are flammable. Avoid open fire or smoking until the gel has dried.
Important Anticholinergic Adverse Reactions
Patients should be informed that anticholinergic (antimuscarinic) agents, such as GELNIQUE, may produce clinically significant adverse reactions related to anticholinergic pharmacological activity including:
- Urinary retention and constipation.
- Heat prostration (due to decreased sweating) when anticholinergics such as GELNIQUE are used in a hot environment.
- Dizziness or blurred vision. Patients should be advised to exercise caution in decisions to engage in potentially dangerous activities until GELNIQUE's effects have been determined.
- Drowsiness that may be worsened by alcohol.
Carcinogenesis, Mutagenesis, Impairment Of Fertility
A 24-month study in rats at dosages of oxybutynin chloride of 20, 80 and 160 mg/kg showed no evidence of carcinogenicity. These doses are approximately 6, 25 and 50 times the maximum exposure in humans taking an oral dose, based on body surface area. Oxybutynin chloride showed no increase of mutagenic activity when tested in Schizosaccharomyces pompholiciformis, Saccharomyces cerevisiae, and Salmonella typhimurium test systems. Reproduction studies with oxybutynin chloride in the mouse, rat, hamster, and rabbit showed no definite evidence of impaired fertility.
Use In Specific Populations
Pregnancy Category B
There are no adequate and well-controlled studies of topical or oral oxybutynin use in pregnant women. Subcutaneous administration to rats at doses up to 25 mg/kg (approximately 50 times the human exposure based on surface area) and to rabbits at doses up to 0.4 mg/kg (approximately 1 times the human exposure) revealed no evidence of harm to the fetus due to oxybutynin chloride. The safety of GELNIQUE administration to women who are or who may become pregnant has not been established. Therefore, GELNIQUE should not be given to pregnant women unless, in the judgment of the physician, the probable clinical benefits outweigh the possible hazards.
It is not known whether oxybutynin is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when GELNIQUE is administered to a nursing woman.
The safety and effectiveness of GELNIQUE 10%® have not been established in pediatric patients .
Of the 496 patients exposed to GELNIQUE in the randomized, double-blind, placebo-controlled 12-week study and the 14-week safety extension study, 188 patients (38%) were 65 years of age and older. No overall differences in safety or effectiveness were observed between these patients and younger patients, but greater sensitivity of some older individuals cannot be ruled out [see CLINICAL PHARMACOLOGY].
There is no experience with the use of GELNIQUE in patients with renal impairment.
There is no experience with the use of GELNIQUE in patients with hepatic impairment.This monograph has been modified to include the generic and brand name in many instances.
