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.

Do not take Tylex if:

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.

• You have asthma (see end of section 2) or any
conditions that affect your breathing
• You have had a serious head injury or raised
pressure on the brain
• You have liver or kidney disease
