Codeine phosphate is a mild to moderate analgesic and has weak cough suppressant activity. As a painkiller, it is often used in conjunction with other painkillers like Paracetamol and Ibuprofen. Codeine is regulated in Ireland as a Class 5 controlled drug and is currently available without prescription through retail pharmacy businesses only, for sale and supply by or under the supervision of a pharmacist. Advice relating to codeine containing medications:

 Unless advised by a doctor do not take for longer than 3 days at a time

 Do not exceed the recommended dose ( always read the label)

 Common side effects include constipation, dizziness, drowsiness and nausea

 Frequent use of these medicines for headaches can make the headaches worse and inevitably lead to a condition known as Medicines Overuse Headache.
