Package Leaflet: Information for the User
Codeisan 28.7 mg Tablets
Codeine Phosphate Hemihydrate
Read all of this leaflet carefully before you start taking this medicine because it contains important information for you.
Contents of the package leaflet:
Codeine phosphate is a water-soluble salt of codeine. Codeine calms cough (antitussive), so it is used in the symptomatic treatment of unproductive cough (cough without secretions).
Codeine can also be used in children over 12 years of age for the short-term treatment of moderate pain that is not relieved by other painkillers such as paracetamol or ibuprofen alone.
This medication contains codeine. Codeine belongs to a group of medications called opioid analgesics that work by relieving pain. It can be used alone or in combination with other painkillers such as paracetamol.
Do not take Codeisan
(listed in section 6),
if you have paralytic ileus (intestinal obstruction) or are at risk of having it,
Warnings and precautions
Consult your doctor or pharmacist before starting to take this medicine.
Children and adolescents
Codeine should not be used to relieve pain in children and adolescents after tonsillectomy or adenoidectomy due to obstructive sleep apnea syndrome.
Codeine is not recommended for use in children with respiratory problems, as the symptoms of morphine toxicity can be worse in these children.
Codeine is not recommended for use in adolescents with respiratory problems for the treatment of cough.
Using Codeisan with other medicines
Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.
However, if your doctor prescribes codeine with sedative medications, your doctor should limit the dose and duration of concomitant treatment.
Tell your doctor about all sedative medications you are taking and closely follow your doctor's dose recommendation. It may be helpful to inform friends or family members who are aware of the signs and symptoms indicated above. Contact your doctor when you experience such symptoms.
Some phenothiazines (used for nervous, mental, or emotional disorders) increase the analgesia induced by codeine, while others decrease it.
Using Codeisan with alcohol
Consuming alcohol may increase drowsiness by potentiating the depressant effect of codeine on the central nervous system.

If you are pregnant, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.
Pregnancy
Codeine is not recommended during pregnancy. Its use may cause physical dependence in the fetus, leading to withdrawal symptoms in the newborn.
Breastfeeding
Do not take codeine if you are breastfeeding. Codeine and morphine pass into breast milk.
Driving and using machines
Codeine may cause drowsiness, altering the mental and/or physical ability required for the performance of potentially hazardous activities, such as driving vehicles or operating machines. Avoid driving vehicles or using machines during treatment.
