What does it do?

Oxycodone is used to relieve strong pain.

Before you start

• Tell your doctor if you have bowel problems, sleep apnoea, if you have ever had a seizure, or have had a recent head injury.
• Tell your doctor if you are pregnant, planning to become pregnant, or breastfeeding.

How should you take it?

Take oxycodone regularly as directed. You can take it with or without food. Swallow whole – do not crush or chew.

What if you forget a dose?

If it is nearly time for your next dose, skip the missed dose and take your next dose at the usual time. Otherwise, take the missed dose as soon as you remember. Do not take two doses at the same time.

Can you take other medicines?

Some medicines available without a prescription may react with oxycodone including:

• sedating antihistamines (e.g. Phenergan®)
• cough suppressants (e.g. Duro-Tuss®, Benadryl Dry Forte®)

Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products (e.g. St John's wort) or recreational drugs.

• Oxycodone ‘short acting’ may be used with oxycodone ‘long acting’ for breakthrough pain.
• Oxycodone can impair your ability to do tasks such as driving or using machines. Alcohol makes this worse. Discuss your risk with your health professional. (search NZTA - Are you safe to drive?)
• Oxycodone may be addictive with long-term use.
• You may see the leftover shell of the tablet in your bowel motions – this is harmless.
