Can I take other medicines if I am using Durogesic DTrans patches?
If you are taking or have recently taken any other medicines you must tell your doctor that you are using Durogesic DTrans patches. This is very important if you need to take a medication called ritonavir (Norvir) and you should not use Durogesic DTrans without discusing this with your doctor.

If you buy any medicines from your pharmacy or chemist you must tell the chemist that you are using Durogesic DTrans patches.
