your pain. If you find that you are still in pain whilst taking
these tablets, discuss this with your doctor.
Do not exceed the dose recommended by your doctor. You

Swallow your tablets whole with water. Do not crush,
dissolve or chew them.
OxyContin Tablets are designed to work properly over
12 hours when swallowed whole. If a tablet is broken,
crushed, dissolved or chewed, the entire 12-hour dose
may be absorbed rapidly into your body. This 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.
Children and adolescents under 18 years of age should not
take the tablets.

Patients with kidney or liver problems

Drinking alcohol whilst taking OxyContin Tablets may make
you feel more sleepy or increase the risk of serious side
effects such as shallow breathing with a risk of stopping
breathing, and loss of consciousness. It is recommended not
to drink alcohol while you’re taking OxyContin Tablets.

Please tell your doctor if you suffer from kidney or liver
problems as they may prescribe a lower dose depending on
your condition.

You should avoid drinking grapefruit juice during your
treatment with this medicine.

Call your doctor or hospital straight away. People who have
taken an overdose may feel very sleepy, sick or dizzy, or
have hallucinations. They may also have breathing difficulties
leading to unconsciousness or even death and may need
emergency treatment in hospital. When seeking medical
attention make sure that you take this leaflet and any
remaining tablets with you to show to the doctor.

call your doctor or pharmacist for advice. Do 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
agitation, anxiety, palpitations, shaking 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 pharmacist.

allergic reactions are rare. Tell your doctor immediately if
you get any sudden wheeziness, difficulties in breathing,
swelling of the eyelids, face or lips, rash or itching especially
those covering your whole body.
The most serious side effect is a condition where you breathe
