What OxyNorm liquid is taken for

OxyNorm liquid contains oxycodone hydrochloride. Oxycodone belongs to a group of medicines called opioid analgesics.
OxyNorm liquid is used to relieve moderate to severe pain.
Your doctor, however, may prescribe it for another purpose.
Ask your doctor if you have any questions about why it has been prescribed for you.
As with all strong painkillers, your body may become used to you taking OxyNorm liquid. Taking it may result in physical dependence. Physical dependence means that you may experience withdrawal symptoms if you stop taking oxycodone suddenly, so it is important to take it exactly as directed by your doctor.
This medicine is only available with a doctor's prescription.

Keep all of your doctor's appointments so that your progress can be checked.
Tell your doctor if your pain is getting worse. Always discuss any problems or difficulties you have while you are taking OxyNorm liquid.

Keep enough OxyNorm liquid with you to last over weekends and holidays.

Things you must not do

Do not drink alcohol while you are taking this medicine.

Do not take OxyNorm liquid to treat any other complaint unless your doctor tells you to.
Do not give your medicine to anyone else, even if they have the same condition as you.

If you need to stop taking this medicine, your doctor will gradually reduce the amount you take each day, if possible, before stopping the medicine completely.

Things to be careful of

Do not drive or operate machinery until you know how OxyNorm liquid affects you.
OxyNorm liquid may cause drowsiness, dizziness, hallucinations, disorientation, blurred vision or other vision problems or may affect alertness. If you are affected, you should not drive or operate machinery. Discuss these effects with your doctor.
Be careful if you are elderly, unwell or taking other medicines.
Some people may experience side effects such as drowsiness, confusion, dizziness and unsteadiness, which may increase the risk of a fall.
If you feel light-headed, dizzy or faint when getting out of bed or standing up, get up slowly.
Standing up slowly will help your body get used to the change in position and blood pressure. If this problem continues or gets worse, talk to your doctor.
Tell your doctor if you suffer from nausea or vomiting when taking OxyNorm liquid.
If you vomit after your dose, your pain may come back, as you may not have absorbed your medicine. If this happens, speak to your doctor. Your doctor may prescribe some medicine to help you stop vomiting.
Tell your doctor if taking OxyNorm liquid causes constipation.
Your doctor can advise about your diet, the proper use of laxatives and suitable exercise you can do to help manage this.
There is potential for abuse of oxycodone and the development of addiction to oxycodone. It is important that you discuss this issue with your doctor.
