Consumer Medicine Information
Limitations of use
ZYDOL 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
ZYDOL 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
ZYDOL 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 ZYDOL 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 ZYDOL
Using ZYDOL with other medicines that can make you feel drowsy such as sleeping capsule (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 ZYDOL.

What is in this leaflet
This leaflet answers some common questions about Zydol capsules. 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 Zydol against the benefits this medicine is expected to have for you.
Talk to your doctor or pharmacist if you have any concerns about taking this medicine.
Keep this leaflet. You may need to read it again.
What Zydol is used for
ZYDOL is used to relieve severe pain which requires daily, long term treatment. It belongs to a group of medicines called opioid analgesics (pain relievers).
Your doctor may have prescribed ZYDOL for another reason. Ask your doctor why this medicine has been prescribed for you.
ZYDOL is available only on a doctor’s prescription.
ZYDOL is for use in adults and children over 12 years of age. It should not be used in children under the age of 12 years or following the removal of tonsils and/or adenoids in people under 18.
Before you use Zydol
When you must not use this medicine
Do not take ZYDOL if:
- you have a known allergy to Zydol or any of the ingredients listed at the end of this leaflet.
Some of the symptoms of an allergic reaction may include skin rash, itching, difficulty breathing and swelling of the face (including lips, tongue, throat, etc).
- you have an allergy to any other medicines known as opioid analgesics, eg. morphine or codeine
- you have respiratory disease or slow or shallow breathing
- you have taken large amounts of alcohol or other substances which can affect your level of consciousness. Some examples of these substances include sleeping pills, pain relievers or other psychotropic medicines (medicines that affect mood and emotions)
- you are taking medicine for depression containing a “monoamine oxidase inhibitor” also known as MAOI, or have taken any within the past two weeks. Examples of MAOI-containing medicines are Nardil®, Parnate®
- you have uncontrolled epilepsy or if your epilepsy is not well controlled by treatment
- you are younger than 12 years old or if you are between 12 – 18 years of age and are recovering from an operation to remove your tonsils and/or adenoids.
Do not take ZYDOL if the packaging is torn or shows signs of tampering.
Do not take ZYDOL after the expiry date which is printed on the carton box. If you take this medicine after the expiry date has passed, it may not work as well.
If it is after the expiry date, or the packaging is damaged, return it to your phamacist for disposal.
You can become addicted to ZYDOL even if you take it exactly as prescribed. ZYDOL 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 ZYDOL. Taking it may result in physical dependence. Physical dependence means that you may experience withdrawal symptoms if you stop taking ZYDOL suddenly, so it is important to take it exactly as directed by your doctor.
Tolerance to ZYDOL may develop, which means that the effect of the medicine may decrease. If this happens, more may be needed to maintain the same effect.
Continue taking your medicine for as long as your doctor tells you. If you stop having this medicine suddenly, your pain may worsen and you may experience some or all of the following withdrawal symptoms:
- nervousness, restlessness, agitation, trouble sleeping or anxiety
- body aches, weakness or stomach cramps
- loss of appetite, nausea, vomiting or diarrhoea
- increased heart rate, breathing rate or pupil size
- watery eyes, runny nose, chills or yawning
- increased sweating.
Very rarely, some patients have experienced the following withdrawal reactions:
- panic attacks
- severe anxiety
- tingling or numbness (pins and needles)
- ringing in your ears
- confusion, delusions or paranoia.
ZYDOL given to the mother during labour can cause breathing problems and signs of withdrawal in the newborn.
If you are not sure whether you should start taking this medicine, talk to your doctor.
