1. What Palladone capsules are and what they are used for

This medicine has been prescribed for you for the relief of severe pain. It contains hydromorphone, which belongs to a class of medicines called opioids, which are ‘pain relievers’. The medicine has been prescribed for you and should not be given to anyone else. Opioids can cause addiction and you may get withdrawal symptoms if you stop taking it suddenly. Your doctor should have explained how long you will be taking it for and when it is appropriate to stop, how to do this safely.

2. What you need to know before you take Palladone capsules

Do not take Palladone capsules if you:

  • are allergic to hydromorphone or to any of the other ingredients of the capsules (listed in section 6);
  • have breathing problems, such as severe chronic obstructive airways disease, respiratory depression or severe asthma. Symptoms may include breathlessness, coughing or breathing more slowly and weakly than expected;
  • have a severe pain in your abdomen;
  • have liver problems;
  • have a condition where the small bowel does not work properly (paralytic ileus);
  • are taking a type of medicine known as a monoamine oxidase inhibitor (examples include tranylcypromine, phenelzine, isocarboxazid, moclobemide and linezolid), or you have taken this type of medicine in the last two weeks;
  • are under 12 years of age.

Warnings and precautions

Talk to your doctor or pharmacist before taking this medicine if you:

  • are or have ever been addicted to opioids, alcohol, prescription medicines, or illegal drugs;
  • have previously suffered from withdrawal symptoms such as agitation, anxiety, shaking or sweating when you have stopped taking alcohol or drugs;
  • feel you need to take more Palladone capsules to get the same level of pain relief, this may mean you are becoming tolerant to the effects of this medicine or are becoming addicted to it. Speak to your doctor who will discuss your treatment and may change your dose or switch you to an alternative pain reliever;
  • have breathing problems, such as severely impaired pulmonary function, chronic obstructive airways disease or reduced respiratory reserve. Your doctor will have told you if you have any of these conditions. Symptoms may include breathlessness and coughing;
  • have a severe headache or feel sick due to a head injury or increased pressure in your skull (for instance due to brain disease). This is because the capsules may make symptoms worse or hide the extent of a head injury;
  • suffer from seizures, fits or convulsions;
  • have a mental disorder as a result of an infection (toxic psychosis);
  • have inflammation of the pancreas (which causes severe pain in the abdomen and back);
  • have an under‐active thyroid gland (hypothyroidism);
  • have low blood pressure (hypotension);
  • have kidney problems;
  • have poor adrenal gland function (your adrenal gland is not working properly which may cause symptoms including weakness, weight loss, dizziness, feeling or being sick);
  • have prostate problems;
  • are suffering from shock (this may make you suddenly feel very light‐headed, faint, cold or clammy and look pale).
  • Suffer from constipation

This medicine may cause breathing problems or worsen already existing problems while sleeping.

These problems may include pauses in breathing during sleep, being awoken by shortness of breath, difficulty staying asleep or excessive daytime drowsiness. If you or someone else observes these symptoms contact your doctor. Your doctor may want to lower your dose.

Taking this medicine regularly, particularly for a long time, can lead to addiction. Your doctor should have explained how long you will be using it for and when it is appropriate to stop, how to do this safely.

Rarely, increasing the dose of this medicine can make you more sensitive to pain. If this happens, you need to speak to your doctor about your treatment.

Addiction can cause withdrawal symptoms when you stop taking this medicine. Withdrawal symptoms can include restlessness, difficulty sleeping, irritability, agitation, anxiety, feeling your heartbeat (palpitations), increased blood pressure, feeling or being sick, diarrhoea, loss of appetite, shaking, shivering or sweating. Your doctor will discuss with you how to gradually reduce your dose before stopping the medicine. It is important that you do not stop taking the medicine suddenly as you will be more likely to experience withdrawal symptoms.

Opioids should only be used by those they are prescribed for. Do not give your medicine to anyone else. Taking higher doses or more frequent doses of opioid may increase the risk of addiction.

Overuse and misuse can lead to overdose and/or death.

If you are going to have an operation, please tell the doctor at the hospital that you are taking these capsules.

You may experience hormonal changes while taking these capsules. Your doctor may want to monitor these changes.

Other medicines and Palladone capsules

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. If you take these capsules with some other medicines, the effect of the capsules or the other medicine may be changed.

These capsules must not be used together with a monoamine oxidase inhibitor, or if you have taken this type of medicine in the last two weeks (see section 2 ‘Do not take…’).

Tell your doctor or pharmacist if you are taking:

  • medicines to help you sleep (for example benzodiazepines, tranquillisers, hypnotics or sedatives);
  • medicines known as barbiturates to either treat fits or to help you sleep;
  • medicines to stop you feeling or being sick;
  • medicines to treat depression;
  • medicines to treat psychiatric or mental disorders (such as neuroleptics);
  • other strong analgesics or ‘painkillers’.

Also tell your doctor if you have recently been given an anaesthetic.

Concomitant use of Palladone capsules and sedative medicines such as benzodiazepines or related drugs increases the risk of drowsiness, difficulties in breathing (respiratory depression), coma and may be life‐threatening. Because of this, concomitant use should only be considered when other treatment options are not possible.

However if your doctor does prescribe Palladone capsules together with sedative medicines the dose and duration of concomitant treatment should be limited by your doctor.

Please tell your doctor about all sedative medicines you are taking, and follow your doctor’s dose recommendation closely. It could be helpful to inform friends or relatives to be aware of the signs and symptoms stated above. Contact your doctor when experiencing such symptoms.

Palladone capsules with alcohol

Drinking alcohol during your treatment with these capsules may make you 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 whilst you are taking Palladone capsules.

Pregnancy and breastfeeding

If you are pregnant or breast‐feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before using this medicine.

Pregnancy

Do not take Palladone capsules if you are pregnant or think you might be pregnant unless you have discussed this with your doctor and the benefits of treatment are considered to outweigh the potential harm to the baby. If you take Palladone capsules during pregnancy your baby may become dependent and experience withdrawal symptoms after the birth which may need to be treated such as high‐pitched cry, jitteriness, fits, poor feeding and diarrhoea.

Breast‐feeding

Do not take Palladone capsules while you are breastfeeding as hydromorphone passes into breast milk and will affect your baby.

Driving and using machines

These capsules may cause a number of side effects such as drowsiness, which could affect your ability to drive or use machinery (see section 4 for a full list of side effects). These are usually most noticeable when you first start taking the capsules, or when changing to a higher dose. If you are affected you should not drive or use machinery.

This 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 while you have this medicine in your body over a specified limit unless you have a defence (called the ‘statutory defence’).
  • This defence applies when:
    • The medicine has been prescribed to treat a medical or dental problem; and
    • You have taken it according to the instructions given by the prescriber and in the information provided with the medicine.
  • Please note that it is still an offence to drive if you are unfit because of the medicine (i.e. your ability to drive is being affected).

Details regarding a new driving offence concerning driving after drugs have been taken in the UK may be found here: https://www.gov.uk/drug‐driving‐law.

Talk to your doctor or pharmacist if you are not sure whether it is safe for you to drive while taking this medicine.

Always take the capsules exactly as your doctor has told you. The label on your medicine will tell you how many capsules to take and how often.

Adults and children over 12 years of age

The usual starting dose is one capsule every 4 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 capsules, discuss this with your doctor.

Children under 12 years of age

Children under 12 years of age should not take the capsules.

Your doctor should have discussed with you how long the course of Palladone capsules will last.

They will arrange a plan for stopping treatment. This will outline how to gradually reduce the dose and stop taking the medicine.

Swallow your capsules whole with a glass of water. If you prefer, you can open the capsules and sprinkle the contents on to cold soft food, such as yoghurt. You must only take the capsules by mouth.

The capsule contents should never be injected as this may lead to serious side effects, which may be fatal.

If you take more Palladone capsules than you should or if someone accidentally swallows your capsules

Call your doctor or hospital straight away as you may need emergency treatment in hospital. People who have taken an overdose may feel very sleepy, sick, dizzy or get pneumonia from inhaling vomit or foreign matter (symptoms include breathlessness, cough and fever). They may also have breathing difficulties leading to unconsciousness or even death. When seeking medical attention make sure that you take this leaflet and any remaining capsules with you to show the doctor.

If you forget to take Palladone capsules

If you miss a dose you should take it as soon as you remember and then carry on as before. Do not take two doses within 4 hours. Do not take a double dose to make up for a forgotten capsule.

If you stop taking Palladone capsules

Do not suddenly stop taking this medicine. If you want to stop taking this medicine discuss this with your doctor first. They will tell you how to do this, usually by reducing the dose gradually so that any unpleasant withdrawal effects are kept to a minimum. Withdrawal symptoms such as restlessness, difficulty sleeping, irritability, agitation, anxiety, feeling your heartbeat (palpitations), increased blood pressure, feeling or being sick, diarrhoea, shaking, shivering or sweating may occur if you suddenly stop taking this medicine.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
