OxyContin tablets contain lactose
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.

3) How to take OxyContin 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.
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

 Redness of the face, reduction in size of the pupils in the eye, muscle
spasm, high temperature.
 A need to take increasingly higher doses of the tablets to obtain the same
level of pain relief (tolerance).
 Colicky abdominal pain or discomfort.
 A worsening of liver function tests (seen in a blood test).

Children and adolescents under 18 years of age should not take the tablets.
Patients with kidney or liver problems
Please tell your doctor if you suffer from kidney or liver problems as they
may prescribe a lower dose depending on your condition.

Rare side effects
(May affect up to 1 in 1,000 people)
 Low blood pressure.
 A feeling of ‘faintness’ especially on standing up.
 Hives (nettle rash).

If you take more OxyContin tablets than you should or if someone
accidentally swallows your tablets
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.

Frequency not known
(Frequency cannot be estimated from the available data)
 An increased sensitivity to pain.

withdrawal symptoms in the newborn. Symptoms to look for in the baby
include irritability, hyperactivity and abnormal sleep pattern, high pitched
cry, shaking, being sick, diarrhoea and not putting on weight.

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.

everybody gets them.

reactions are rare. Tell your doctor immediately if you get any sudden
