before taking Dolocodon if:

•    You have an under-active thyroid gland (hypothyroidism), as you may need a lower dose of this medicine

•    You have problems with your adrenal glands (Addison's disease)

•    You have prostate problems (enlargement of the prostate gland)

•    You are going to have an operation (including dental surgery)

If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before taking this medicine.

Taking other medicines

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines. This includes medicines obtained without a prescription, including herbal medicines. This is because Dolocodon can affect the way some other medicines work. Also, some other medicines can affect the way Dolocodon works.

Do not take Dolocodon and tell your doctor if you are taking

• Medicines to treat depression called MAOIs (monoamine oxidase inhibitors) or have taken them in the last 2 weeks.

Tell your doctor or pharmacist if you are taking any of the following medicines:

•    Medicines to help you sleep (hypnotics, sedatives) or make you less anxious (tranquillisers)

•    If you have recently been given a medicine for muscle relaxation or are due to have an anaesthetic (to put you to sleep for an operation)

Taking Dolocodon with food and drink

You can take Dolocodon with or without food.

Drinking alcohol whilst taking Dolocodon 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 Dolocodon.

Pregnancy and breast-feeding

•    Do not use this medicine if you are pregnant, think you may be pregnant or plan to get pregnant. This is because taking Dolocodon regularly during pregnancy may cause your baby to have some “withdrawal symptoms” (see Section 3 - If you stop taking Dolocodon) when it is first born. Also, taking Dolocodon during delivery can cause your baby to have breathing problems when it is born

•    Do not use this medicine if you are breast-feeding or planning to breast-feed as Dolocodon can pass into your breast milk.

Driving and using machines

You should discuss with your doctor before taking Dolocodon whether or not you should drive or use machines or tools. You may feel less alert and be much slower to react to situations than usual while taking Dolocodon.

If this happens, do not drive or use any tools or machines.

The medicine can affect your ability to drive as it may make you sleepy or dizzy.

•    Do not drive while taking this medicine until you know how it affects you.

•    It is an offence to drive if this medicine affects _your ability to drive.

•    However, you would not be committing an offence if:

o The medicine has been prescribed to treat a medical or dental problem and o You have taken it according to the

instructions given by the prescriber or in the information provided with the medicine and o It was not affecting your ability to drive safely Talk to your doctor or pharmacist if you are not sure whether it is safe for you to drive while taking this medicine.

Important information about some of the ingredients of Dolocodon

Dolocodon contains sucrose. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before you take this medicine.

3. HOW TO TAKE DOLOCODON

Always take Dolocodon exactly as your doctor has told you. The dose of Dolocodon will depend on your needs, the illness you are being treated for and how you respond to treatment. The dose will be decided by your doctor. The usual doses are listed below. Check with your doctor or pharmacist if you have any questions about your medicine and how to take it.

Dolocodon 10, 20 and 40 tablets have break scores on both sides. The tablet can be divided into equal halves.

Taking this medicine

•    Swallow the tablets whole or halved with a drink of water

•    Do not crush or chew the tablets as this will affect the way the medicine is taken into your body and could cause you to have too much medicine in your body at once. (See “If you take more Dolocodon than you should”)

•    Try to take your medicine at the same times each day so that it becomes part of your daily routine

•    Leave 12 hours between doses

How much to take

Adults and children aged 12 years and over

•    Your doctor will tell you exactly how much Dolocodon to take. This will depend on your medical condition, whether or not you have taken opioid medicines before and how you respond to treatment.

•    The usual starting dose of Dolocodon is 10mg every 12 hours

•    For the treatment of non-cancer pain, a total daily dose of 40mg is usually enough to control the pain

•    Patients with cancer pain usually need a total daily dose of between 80mg and 120mg of this medicine. This may be increased, by a doctor, to as much as 400mg each day for some patients.

People with liver or kidney problems or people with a low body weight

•    Your doctor may lower your dose

Children (under the age of 12 years)

•    Dolocodon should not be given to children under 12 years of age.

If you take more Dolocodon than you should

Taking too much of this medicine may be dangerous. If you have taken too many tablets, or if someone accidentally swallows some, contact your doctor or go to the nearest hospital casualty department immediately. Signs that someone has taken too much Dolocodon include breathing problems which may lead to unconsciousness or even death.

Remember to take the pack and any remaining tablets with you so that the doctor knows what has been taken.

If you forget to take Dolocodon

If you forget to take a dose at the right time, you may not get enough pain relief. 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 Dolocodon

Do not change the dose or suddenly stop treatment without discussing this with your doctor. This is because suddenly stopping treatment can cause side effects (withdrawal symptoms) in some people. These side effects can include: becoming agitated, anxious or nervous, very fast, uneven or forceful heartbeat (palpitations), shaking, or sweating.

4. POSSIBLE SIDE EFFECTS

As with all medicines, Dolocodon can cause side effects, although not everybody gets them.

Most people will have constipation when they take these tablets. Your doctor can prescribe a laxative to overcome this problem.

You may feel sick or vomit (be sick) when you take your tablets. Your doctor can prescribe an anti-vomiting medicine if it causes problems.

You may find that you cannot concentrate or that you feel more sleepy than normal when you start taking your tablets or when your dose is increased. This should wear off after a few days.

The following side effects may happen with this medicine:

Stop taking Dolocodon and see a doctor or go

to a hospital straight away if:

•    You get swelling of your hands, feet, ankles, face, lips or throat which may cause difficulty in swallowing or breathing. You could also notice an itchy, lumpy rash (hives) or nettle rash (urticaria).

This may mean you are having an allergic reaction to Dolocodon

•    Your breathing becomes very slow and weak. You may also feel dizzy or faint.

— These could be signs of a very serious

problem called respiratory depression. This is more likely to happen if you are elderly or have other major health problems

•    You get a bloated feeling and cramping pain in your stomach (abdomen), are sick (vomit) and also have some of the following symptoms: indigestion,

heartburn, an upset stomach, constipation, loss of appetite, dry mouth. This could be caused by an obstruction or blockage of the bowel which needs urgent medical attention.

Tell your doctor as soon as possible if:

•    You have fits (convulsions). This is more likely to happen in patients who already have epilepsy or a tendency to have fits

Becoming dependent on Dolocodon

Taking Dolocodon tablets regularly for a long time can make you become dependent on them. This may mean that you feel as if you need to have Dolocodon more often or at a higher dose to get the same level of pain relief. Tell your doctor as soon as possible if you think this is happening to you. Do not change the amount of Dolocodon you take, or how often you take it, without talking to your doctor first.
