Oxybutynin is primarily used to treat overactive bladder syndrome, helping to reduce symptoms such as frequent urination, urgency, and incontinence. It works by relaxing the bladder muscles, which decreases involuntary contractions and increases bladder capacity. Additionally, it is prescribed for managing urinary leakage in individuals with neurological conditions like spinal cord injuries or multiple sclerosis. It is also used in children for nocturnal enuresis to help control nighttime urination. In some cases, it is used to treat excessive sweating (hyperhidrosis) due to its anticholinergic properties. The medication is available in various forms, including oral tablets, transdermal patches, and topical gels, to suit different patient needs. Common side effects may include dry mouth, constipation, and dizziness. Always consult a healthcare provider for proper dosage and administration.
