What is Oxybutynin?

Oxybutynin ER 5mg is the extended-release form of oxybutynin, sold under the brand name Ditropan XL. It belongs to a class of medications called anticholinergics (antimuscarinics), which work by relaxing the smooth muscle of the bladder. This reduces bladder spasms that cause sudden urges to urinate, leakage, and frequent trips to the bathroom. The extended-release tablet releases medication slowly, allowing convenient once-daily dosing.

What it treats

• Overactive bladder with urge urinary incontinence
• Urinary urgency
• Urinary frequency
• Detrusor overactivity associated with a neurological condition (pediatric patients 6 years and older)

• Adults: 5–10 mg by mouth once daily; may increase in 5 mg increments weekly as needed (max 30 mg/day).
• Pediatric patients 6 years and older: 5 mg by mouth once daily; may titrate (max 20 mg/day).
• Swallow tablets whole with liquid; do not chew, crush, or divide.

Your prescriber will determine the dose and duration that are right for you. Always follow the directions on your prescription label.
