1. What Oxybutynin is and what it is used for

Oxybutynin contains a medicine called oxybutynin hydrochloride. This belongs to two groups of medicines called ‘anticholinergics’ and ‘antispasmodics’.

It works by relaxing the muscles of the bladder and stops sudden muscle contractions (spasms). This helps control the release of water (urine).

Oxybutynin can be used in adults and children 5 years or older to treat:

  • loss of control in passing water (urinary incontinence)
  • increased need or urgency to pass water (urine)
  • night time bedwetting, when other treatments have not worked

You must talk to a doctor if you do not feel better or if you feel worse

2. What you need to know before you take Oxybutynin

Do not take Oxybutynin if:

  • you are allergic (hypersensitive) to oxybutynin hydrochloride or any of the other ingredients (see section 6 ‘Contents of the pack and other information’).

Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue.

  • you have a rare muscle illness called ‘Myasthenia gravis’
  • you have increased pressure in the eye (glaucoma)
  • your gut (stomach or intestine) is blocked, perforated or not working properly
  • you have a severe form of a condition known as ‘ulcerative colitis’
  • you have a blockage that makes it difficult for you to pass water (urine).

Do not take this medicine if any of the above applies to you. If you are not sure, talk to your doctor or pharmacist before taking Oxybutynin.
