Oxybutynin — Uses, Dosage, Side Effects & Safety
Drug class: Anticholinergic, Antimuscarinic agent
Overview
Oxybutynin is a medication used to treat symptoms of overactive bladder, such as frequent urination, urgency, and urinary incontinence (leakage). It is also prescribed for certain bladder muscle conditions, including neurogenic bladder, in both adults and children. Oxybutynin works by relaxing the muscles in the bladder, which helps reduce sudden urges to urinate and the number of bathroom visits. It belongs to a group of medicines called anticholinergics or antimuscarinics. Key points for patients: Oxybutynin can help improve quality of life for people with bladder control problems, but it may cause side effects like dry mouth and constipation. It is important to take it exactly as prescribed and to discuss any concerns or side effects with your healthcare provider.
