Important information about some of the ingredients of OxyContin
These tablets contain lactose which is a form of sugar. If you have been
told by your doctor that you have an intolerance to some sugars, contact
your doctor before taking these tablets.
Always take these tablets exactly as 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)
The usual starting dose is one 10 mg tablet every 12 hours. However, your
doctor will prescribe the dose required to treat 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 should check
with your doctor or pharmacist if you are not sure.
Swallow your tablets whole with water. Do not crush, dissolve or chew
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.

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.
If you forget to take your OxyContin tablets
If you remember within 4 hours of the time your tablet was due, take your
tablet straight away. Take your next tablet at your normal time. If you are
more than 4 hours late, please 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.
