1. What Lyrinel is and what it is used for
What Lyrinel is
Lyrinel contains a medicine called oxybutynin hydrochloride. This
belongs to a group of medicines called ‘anticholinergics’ or
How Lyrinel works
Lyrinel works by relaxing your bladder muscles. It also stops bladder
contractions and delays the desire to pass urine (water).
Your tablets are made in a 'prolonged release' form. The tablets are
coated with a special ‘membrane’ which slowly release the medicine.
This membrane may pass through your body unchanged. This does not
affect the way the medicine works.
What Lyrinel is used for
Lyrinel can be used:
• To help adults control when and how often they pass urine
• In children 5 years or older to treat:
o Loss of control in passing urine (urinary incontinence)
o Increased need or urgency to pass urine
o Night time bedwetting, when other treatments have not worked.

a disease that causes frequent diarrhoea

If you are not sure if any of the above apply to you, talk to your doctor,
nurse or pharmacist before taking Lyrinel.
Hot weather or fever
Care must be taken when using Lyrinel in hot weather or in people with a
fever. This is because Lyrinel reduces the amount a person sweats. This
can lead to heat exhaustion and heat stroke.
Taking other medicines
Please tell your doctor, nurse or pharmacist if you are taking or have
recently taken any other medicines. This includes medicines obtained
without a prescription and herbal therapies. This is because Lyrinel can
affect the way some other medicines work. Also, some other medicines
can affect the way Lyrinel works.

In particular, tell your doctor, nurse or pharmacist if you are taking any of
the following medicines:
• For mental problems such as phenothiazines or butyrophenones and
• For depression called tricyclic antidepressants (such as amitriptyline or
• For Parkinson’s disease such as amantadine or levodopa
• For allergy called ‘antihistamines’ (such as chlorphenamine or

hyoscine for nausea
• For dementia such as donepezil, rivastigmine, galantamine or tacrine
• Placed under the tongue to treat angina (sublingual nitrates)
• For fungal infections such as ketoconazole, itraconazole and
• Antibiotics called ‘macrolides’ (such as erythromycin)
• Domperidone and metoclopramide – used to stop you feeling sick
(nausea) or being sick (vomiting).

nurse or pharmacist before taking this medicine.
Pregnancy and breast-feeding
• Talk to your doctor, nurse or pharmacist before taking Lyrinel if you are
pregnant, might become pregnant or think you may be pregnant.

amounts may pass into your milk.

happens, do not drive or use any tools or machines.
