your doctor has told you. The label on
your medicine will tell you how many
tablets to take and how often.
Adults (over 18 years of age)

OxyContin tablets are designed to

can be dangerous, causing serious
problems such as an overdose, which
may be fatal.

You should take your tablets every
12 hours. For instance, if you take a
tablet at 8 o’clock in the morning, you
should take your next tablet at 8 o’clock
in the evening.
You must only take the tablets by
mouth. The tablets should never be
crushed or injected as this may lead to
serious side effects, which may be fatal.

attention make sure that you take this
leaflet and any remaining tablets with

not take a double dose to make up for a
forgotten tablet.
If you stop taking OxyContin tablets
You should not suddenly stop taking
these tablets unless your doctor tells
you to. If you want to stop taking your
tablets, discuss this with your doctor
first. They will tell you how to do this,
usually by reducing the dose gradually
so you do not experience unpleasant
effects. Withdrawal symptoms such as

or sweating may occur if you suddenly
stop taking these tablets.
If you have any further questions on the
use of this medicine, ask your doctor or
