Consumer Medicine Information
Limitations of Use
ASPALGIN should only be used when your doctor decides that other treatment options are not able to effectively manage your pain or you cannot tolerate them.
Hazardous and Harmful Use
ASPALGIN poses risks of abuse, misuse and addiction which can lead to overdose and death. Your doctor will monitor you regularly during treatment.
Life Threatening Respiratory Depression
ASPALGIN can cause life-threatening or fatal breathing problems (slow, shallow, unusual or no breathing), even when used as recommended. These problems can occur at any time during use, but the risk is higher when first starting ASPALGIN and after a dose increase, if you are older, or have an existing problem with your lungs. Your doctor will monitor you and change the dose as appropriate.
Use of Other Medicines While Using ASPALGIN
Using ASPALGIN with other medicines that can make you feel drowsy such as sleeping tablets (e.g. benzodiazepines), other pain relievers, antihistamines, antidepressants, antipsychotics, gabapentinoids (e.g. gabapentin and pregabalin), cannabis and alcohol may result in severe drowsiness, decreased awareness, breathing problems, coma and death.
Your doctor will minimise the dose and duration of use; and monitor you for signs and symptoms of breathing difficulties and sedation. You must not drink alcohol while using ASPALGIN.

What is in this leaflet

This leaflet answers some common questions about ASPALGIN. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist.
All medicines have risks and benefits. Your doctor has weighed the risks of you taking ASPALGIN against the benefits they expect it will have for you.
If you have any concerns about taking this medicine, ask your doctor or pharmacist.
Keep this leaflet with the medicine.
You may need to read it again.

What ASPALGIN is used for

This medicine is used for the temporary relief of acute moderate pain, inflammation and fever.
This medicine contains the active ingredients aspirin and codeine phosphate hemihydrate.
Aspirin belongs to a group of medicines called analgesics which are used to block pain. It is also an antipyretic. That means it helps reduce your body temperature if you have a fever.
Codeine phosphate hemihydrate belongs to a group of medicines called opioid analgesics and it acts by blocking pain and your emotional response to pain.
You can become addicted to ASPALGIN even if you take it exactly as prescribed. ASPALGIN may become habit forming causing mental and physical dependence. If abused it may become less able to reduce pain.
As with all other opioid containing products, your body may become used to you taking ASPALGIN. Taking it may result in physical dependence. Physical dependence means that you may experience withdrawal symptoms if you stop taking ASPALGIN suddenly, so it is important to take it exactly as directed by your doctor.
Tolerance to ASPALGIN may develop, which means that the effect of the medicine may decrease. If this happens, more may be needed to maintain the same effect.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another reason.

Aspirin has been implicated in cases of Reye’s Syndrome, a potentially fatal illness which results from brain inflammation.
Do not take ASPALGIN if you have a stomach ulcer.
Elderly patients are more likely to have less effective kidney or liver function due to age. This may increase the risk of side effects. You should discuss how much ASPALGIN to take with your doctor or pharmacist.
