1. What Codeine Phosphate Solution for Injection is and what it is used for
This medicine 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 such as paracetamol.
This medicine is a solution for injection for intramuscular use and is used for the relief of mild to
moderate pain.
This medicine can be used in 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.

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
