Oxybutynin gel is a prescription medication used to manage certain bladder conditions. This topical medication is designed for absorption through the skin, delivering its therapeutic effects systemically. It offers an alternative delivery method compared to oral medications. The gel formulation allows for convenient application directly onto the skin.
What Oxybutynin Gel Treats
Oxybutynin gel is primarily prescribed to address the symptoms of overactive bladder (OAB). Individuals with OAB often experience frequent urination, a sudden and strong urge to urinate, and urge urinary incontinence, which is the involuntary leakage of urine due to a sudden urge.
The gel works by relaxing the muscles in the bladder, thereby reducing these unwanted contractions. Oxybutynin is classified as a muscarinic antagonist, a type of medication that blocks the action of acetylcholine, a neurotransmitter involved in bladder muscle contraction. By blocking these receptors, the bladder muscles can relax, increasing the bladder’s capacity and reducing the frequency and urgency of urination.
How to Apply Oxybutynin Gel
The gel is typically applied once daily to clean, dry, and intact skin. Recommended application sites include the abdomen, upper arms, shoulders, or thighs. Rotate the application site daily to avoid skin irritation.
After dispensing the gel, gently rub it into the chosen skin area until it dries completely. It is important to wash your hands thoroughly with soap and water immediately after applying the gel to prevent accidental transfer to other areas or individuals. Avoid contact with eyes, nose, or mouth; if this occurs, rinse the area with water. Avoid bathing, swimming, or getting the application site wet for at least one hour after applying the gel. You should also avoid applying other lotions, powders, or oils to the treatment area.
Potential Side Effects
Common side effects include dry mouth, constipation, and headache. Some individuals may also experience localized reactions at the application site, such as redness, rash, itching, or irritation.
Less common but potentially more serious side effects warrant immediate medical attention. These include blurred vision, dizziness, or drowsiness, which can impair the ability to drive or operate machinery. Confusion, agitation, or hallucinations are also possible, especially when first starting the medication or after a dosage increase. If you experience severe or persistent side effects, or any signs of a severe allergic reaction like swelling of the face, lips, or tongue, or difficulty breathing, contact a healthcare professional.
Important Warnings and Precautions
The medication should not be used by individuals with certain pre-existing conditions, including uncontrolled narrow-angle glaucoma, a blockage in the stomach or intestines, or an inability to urinate.
Care should be exercised when using oxybutynin gel with other medications, particularly other anticholinergic drugs, as this can increase the risk of side effects. Certain antifungals might also interact with oxybutynin, so disclose all current medications to your healthcare provider. Specific populations, such as elderly patients, may experience more pronounced side effects, including increased confusion or drowsiness. Individuals with liver or kidney impairment, or those who are pregnant or breastfeeding, should discuss the risks and benefits with their doctor before using this medication.
