Frequently asked questions

Is oxycodone stronger than morphine?

It is roughly comparable or somewhat stronger by weight; doses are worked out by the doctor when switching.

Can I crush my slow-release tablet?

No. Crushing or chewing releases all the medicine at once, which can be fatal.

Will I have withdrawal if I stop?

After regular use, yes, it is possible. Your doctor will taper it.
