How does oxybutynin work?
Oxybutynin blocks certain nerve signals to the bladder, preventing spasms and helping the bladder hold more urine, reducing urgency and frequency.
What is oxybutynin used to treat?
Oxybutynin is commonly prescribed for:
- Overactive bladder (OAB) (to reduce sudden urges and leakage)
- Urinary incontinence (to help prevent accidental leakage)
- Frequent urination (to space out trips to the toilet)
- Bladder conditions caused by neurological disorders (such as multiple sclerosis or spina bifida)
Who can take oxybutynin?
Oxybutynin is suitable for most adults and children over 5 years old, depending on the condition being treated.
Who might not be able to take oxybutynin?
Oxybutynin may not be suitable if you:

Can I take oxybutynin if I’m pregnant or breastfeeding?
Oxybutynin isn’t usually recommended during pregnancy or breastfeeding, but your doctor will assess if the benefits outweigh the risks.
What if I miss a dose?
If you forget a dose, take it as soon as you remember. If it’s close to your next dose, skip the missed one—do not take two doses at once.
How effective is oxybutynin?
Oxybutynin is highly effective at reducing bladder urgency and incontinence when taken consistently.
What should I do if I take too much?
Taking too much oxybutynin can cause severe drowsiness, dry mouth, confusion, or difficulty urinating. If you think you’ve taken too much, seek medical help immediately.
What dose of oxybutynin is usually taken?
- For overactive bladder and incontinence: 5mg two to three times daily (standard tablets) or 5mg to 10mg once daily (extended-release tablets)
- For children with bladder conditions: Dose varies and should be prescribed by a doctor
Your doctor will determine the correct dose based on your condition.
