1. What Tylex is for
Tylex can be used in adults and children over 12 years of age for the short-term
relief of moderate pain that is not relieved by other painkillers such as
paracetamol or ibuprofen alone. This product contains codeine. Codeine
belongs to a group of medicines called opioid analgesics which act to relieve
pain. It can be used on its own or in combination with other pain killers.

2. Before you take Tylex
Important information about Tylex:
• Do not take for longer than directed by your prescriber
• Taking codeine regularly for a long time can lead to addiction, which
might cause you to feel restless and irritable when you stop the tablets
• Taking a painkiller for headaches too often or for too long can make
them worse

Warnings and precautions
Codeine is transformed to morphine in the liver by an enzyme. Morphine is
the substance that produces pain relief. Some people have a variation of this
enzyme and this can affect people in different ways. In some people,
morphine is not produced or produced in very small quantities, and it will not
provide enough pain relief. Other people are more likely to get serious side
effects because a very high amount of morphine is produced. If you notice
any of the following side effects, you must stop taking this medicine and seek
immediate medical advice: slow or shallow breathing, confusion, sleepiness,
small pupils, feeling or being sick, constipation, lack of appetite.
Children and adolescents
Use in children and adolescents after surgery
Codeine should not be used for pain relief in children and adolescents after
removal of their tonsils or adenoids due to Obstructive Sleep Apnoea Syndrome.
Use in children with breathing problems
Codeine is not recommended in children with breathing problems, since the
symptoms of morphine toxicity may be worse in these children.
Check with your doctor before taking Tylex if:
• You have had a serious head injury or raised pressure on the brain
• You have any condition that affects your breathing
• You have liver or kidney disease
• You have an under-active thyroid gland
• You suffer from urinary problems (e.g. difficulty in passing water)
including those associated with an enlarged prostate gland
• You have a disease of the Adrenal gland called Addison’s disease
• You have decreased brain functioning
• You have inflammatory or obstructive bowel disorders
• You have a condition which weakens the muscles called myasthenia gravis
• You have been told to restrict your sodium intake
• You have a metabolic disorder called phenylketonuria, which requires
a diet low in an amino acid called phenylalanine
• You are elderly
• You feel weak
• You are debilitated
If any of the above applies to you, talk to your doctor before taking Tylex.
Taking other medicines
• Do not take Tylex with any other paracetamol-containing
products. Many other medicines contain paracetamol, including
some you can buy without a prescription (for example some
cold and “flu” remedies).
Tell your doctor if you are taking any of the following medicines:
• Medicines to treat anxiety or depression
• Other painkillers
• Medicines to help you sleep
• Warfarin (a medicine used to thin the blood)
• Medicines used to treat stomach problems, sickness or feeling sick
• Products used to treat diarrhoea (including metaclopramide and
• Cholestyramine (a medicine used to lower cholesterol levels in the blood)
• Medicines to help relax muscles
• Any other medicine, including medicines obtained without a prescription
If any of the above applies to you, talk to your doctor before taking Tylex.

Taking Tylex with food and drink
Do not drink alcohol whilst taking Tylex. If you regularly drink large amounts of
alcohol, you are at risk of damaging your liver when taking paracetamol.
Pregnancy and breast-feeding
Do not take Tylex if you are pregnant or trying to become pregnant without
first talking to your doctor. Do not take codeine while you are breastfeeding.
Codeine and morphine passes into breast milk.
Driving and using machines
Tylex may make you feel dizzy or tired. If this happens to you, do not drive a
vehicle, operate machinery or carry out complex tasks.
Warnings about the ingredients in Tylex
• Tylex contains 25 mg of aspartame per tablet. This may be harmful to
people with an inherited metabolic disease called phenylketonuria.
• Tylex contains 326.6 mg of sodium per tablet and may not be suitable for
people on a controlled sodium diet.
Tell your doctor or pharmacist before taking this medicine if either of the above
statements applies to you.
