Can I fill a prescription for my usual S8 (restricted narcotic medication such as morphine and oxycodone) medication while I am interstate?
No, it is against the law. You must either take sufficient medication with you, or arrange for an interstate doctor to write a new prescription for you. It is unwise to carry large quantities of S8 medication at any time, but particularly while travelling. If you are going interstate for a long time (months), you will need to make arrangements well in advance for an interstate doctor to do this – ask your doctor here for advice.
