Oxybutynin ER is available in both short-acting and long-acting forms, while fesoterodine is only available as an extended-release tablet. Oxybutynin can be used in children as young as 5 years old for certain conditions, whereas fesoterodine is approved for children 6 years and older with neurogenic detrusor overactivity (NDO). Both medications can cause dry mouth, constipation, dizziness, and drowsiness, especially in older adults. Fesoterodine cannot be used by people allergic to tolterodine (Detrol). Additionally, both medications are available as a lower-cost generic.
