• if you are allergic to buprenorphine or any of the other ingredients of this medicine (listed in section 6)
• if you have breathing problems
• if you are addicted to drugs
• if you 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
• if you suffer from myasthenia gravis (a condition in which the muscles become weak)
• if you have previously suffered from withdrawal symptoms such as agitation, anxiety, shaking or sweating upon stopping taking alcohol.

Panitaz must not be used to treat symptoms associated with drug withdrawal.

Talk to your doctor, pharmacist or nurse before using Panitaz:

• if you have previously suffered from withdrawal symptoms such as agitation, anxiety, shaking or sweating, when you have stopped taking alcohol or drugs
• are treated with antidepressants. The use of these medicines together with Panitaz can lead to serotonin syndrome, a potentially life-threatening condition (see “Other medicines and Panitaz”)
• if you suffer from seizures, fits or convulsions
• suffer from a breathing related sleep disorder (sleep apnoea);
• if you 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 patches may make symptoms worse or hide the extent of a head injury
• if you are feeling light-headed or faint
• if you have severe liver problems
• if you have a high temperature, as this may lead to larger quantities of the active ingredient being absorbed into the blood than normal.
• If you suffer from constipation.

Tolerance, dependence, and addiction

This medicine contains buprenorphine which is an opioid medicine. Repeated use of opioids can result in the drug being less effective (you become accustomed to it, known as tolerance). Repeated use of Panitaz can also lead to dependence, abuse, and addiction, which may result in life-threatening overdose. The risk of these side effects can increase with a higher dose and longer duration of use.

Dependence or addiction can make you feel that you are no longer in control of how much medicine you need to take or how often you need to take it.

The risk of becoming dependent or addicted varies from person to person. You may have a greater risk of becoming dependent on or addicted to Panitaz if:

• You or anyone in your family have ever abused or been dependent on alcohol, prescription medicines or illegal drugs (“addiction”).
• You are a smoker.
• You have ever had problems with your mood (depression, anxiety, or a personality disorder) or have been treated by a psychiatrist for other mental illnesses.

If you notice any of the following signs whilst taking [product name], it could be a sign that you have become dependent or addicted:

• You need to take the medicine for longer than advised by your doctor
• You need to take more than the recommended dose
• You might feel that you need to carry on taking your medicine, even when it doesn’t help to relieve your pain.
• You are using the medicine for reasons other than prescribed, for instance, ‘to stay calm’ or ‘help you sleep’
• You have made repeated, unsuccessful attempts to quit or control the use of the medicine
• When you stop taking the medicine you feel unwell, and you feel better once taking the medicine again (‘withdrawal effects’)

If you notice any of these signs, speak to your doctor to discuss the best treatment pathway for you, including when it is appropriate to stop and how to stop safely (see section 3, If you stop taking Panitaz).

Opioids should only be used by those they are prescribed for. Do not give your medicine to anyone else.

Panitaz can cause sleep-related breathing disorders such as sleep apnoea (breathing pauses during sleep) and sleep related hypoxemia (low oxygen level in the blood). The symptoms can include breathing pauses during sleep, night awakening due to shortness of breath, difficulties to maintain sleep or excessive drowsiness during the day. If you or another person observe these symptoms, contact your doctor. A dose reduction may be considered by your doctor.

This medicine may cause application site reactions which are usually presented by a mild or moderate skin inflammation, and their typical appearance may include redness, swelling, itching, rash, small blisters, and painful/burning sensation at the application site. Most commonly the cause is skin irritation, and these reactions stop after Panitaz patches are removed. More serious allergic reactions may occur such as blisters with discharge, which may spread outside the application site and may not resolve rapidly after Panitaz removal. Chronic allergic reactions may lead to open wounds, bleeding, ulcers, skin discoloration and infections. If you notice any of the above skin reactions, please contact your doctor.

This medicine may increase your sensitivity to pain particularly at high doses. Tell your doctor if this happens. A reduction in your dose or a change in your medicine may be necessary.

If you have recently had an operation, please speak to your doctor before using these patches.

Similar to other opioids, Panitaz patches may affect the normal production of hormones in the body, such as cortisol or sex hormones, particularly if you have taken high doses for long period of time.

Do not give this medicine to children below 18 years.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Some medicines may increase the side effects of Panitaz patches and may sometimes cause very serious reactions. Do not take any other medicines whilst taking Panitaz patches without first talking to your doctor, especially:

• Gabapentin or pregabalin to treat epilepsy or pain due to nerve problems (neuropathic pain).
• Antidepressants such as moclobemide, tranylcypromine, citalopram, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, duloxetine, venlafaxine, amitriptyline, doxepine, or trimipramine. These medicines may interact with Panitaz and you may experience symptoms such as involuntary, rhythmic contractions of muscles, including the muscles that control movement of the eye, agitation, hallucinations, coma, excessive sweating, tremor, exaggeration of reflexes, increased muscle tension, body temperature above 38°C. Contact your doctor when experiencing such symptoms.
• Panitaz patches must not be used together with a type of medicine known as a monoamine oxidase inhibitor (examples include tranylcypromine, phenelzine, isocarboxazid, moclobamide and linezolid), or if you have taken this type of medicine in the last two weeks.
• If you take some medicines such as phenobarbital or phenytoin (medicines commonly used to treat seizures, fits or convulsions), carbamazepine (a medicine to treat seizures, fits or convulsions and certain pain conditions), or rifampicin (a medicine to treat tuberculosis) the effects of Panitaz patches may be reduced.
• Medicines used to treat allergies, travel sickness or nausea (antihistamines or antiemetics).
• Panitaz patches may make some people feel drowsy, sick or faint or make them breathe more slowly or weakly. These side effects may be made worse if other medicines that produce the same effects are taken at the same time. These include certain medicines to treat pain, depression, anxiety, psychiatric or mental disorders (antipsychotics and neuroleptics), medicines to help you sleep, medicines to treat high blood pressure such as clonidine, other opioids (which may be found in painkillers or certain cough mixtures e.g. morphine, dextropropoxyphene, codeine, dextromethorphan, noscapine), antihistamines which make you drowsy, or anaesthetics such as halothane.
• Muscle relaxants;
• Medicines to treat Parkinson’s disease;
• Concomitant use of Panitaz and sedative medicines such as benzodiazepines or related drugs may increase 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 Panitaz 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.

Alcohol may make some of the side effects worse and you may feel unwell if you drink alcohol whilst wearing Panitaz patches. Drinking alcohol whilst using Panitaz patches may also affect your reaction time.

Do not use Panitaz patches if you are pregnant or think you may be pregnant unless you have discussed this with your prescriber and the benefits of treatment are considered to outweigh the potential harm to the baby.

If you use Panitaz patches during pregnancy, your baby may become dependent and experience withdrawal symptoms after the birth which may need to be treated.

Do not use Panitaz while you are breastfeeding as buprenorphine passes into breast milk and will affect your baby.

Ask your doctor or pharmacist for advice before taking this medicine.

Panitaz patches may affect your reactions to such an extent that you may not react adequately or quickly enough in the event of unexpected or sudden occurrences. This applies particularly:

• at the beginning of treatment
• if you are taking medicines to treat anxiety or help you sleep
• if your dose is increased.

If you are affected (e.g. feel dizzy, drowsy or have blurred vision), you should not drive or operate machinery whilst using Panitaz patches, or for 24 hours after removing the patch.

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 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.

Unless your doctor has told you differently, attach one Panitaz patch (as described in detail below) and change it every seventh day, preferably at the same time of day. Your doctor may wish to adjust the dose after 3-7 days until the correct level of pain control has been found. If your doctor has advised you to take other painkillers in addition to the patch, strictly follow the doctor’s instructions, otherwise you will not fully benefit from treatment with the Panitaz patch. The patch should be worn for 3 full days before increasing the dose, this is when the maximum effect of a given dose is established.

Panitaz patches should not be used in patients below the age of 18 years.

In patients with kidney disease, no change in dose is necessary.

In patients with liver disease, the effects and period of action of the Panitaz patch may be affected and your doctor will therefore check on you more closely.

• Choose an area of non-irritated, intact skin on your upper arm, outer arm, upper chest, upper back or side of the chest (see illustrations below). Ask for assistance if you cannot apply the patch yourself.

• The Panitaz patch should be applied to a relatively hairless or nearly hairless skin site. If no suitable hair free sites are available the hairs should be cut off with a pair of scissors. Do not shave them off.
• Avoid skin which is red, irritated or has any other blemishes, for instance large scars.
• The area of skin you choose must be dry and clean. If necessary, wash it with cold or lukewarm water. Do not use soap, alcohol, oil, lotions or other detergents. After a hot bath or shower, wait until your skin is completely dry and cool. Do not apply lotion, cream or ointment to the chosen area. This might prevent your patch from sticking properly.

Step 1: Each transdermal patch is sealed in a sachet. Just before use, cut the sachet along the sealed edge with scissors. Take out the transdermal patch. Do not use the patch if the sachet seal is broken.

Step 2: The sticky side of the transdermal patch is covered with a transparent protective foil. Carefully peel off one part of the foil. Try not to touch the sticky part of the transdermal patch.

Step 3: Stick the transdermal patch on to the area of skin you have chosen and remove the remaining foil.

Step 4: Press the transdermal patch against your skin with the palm of your hand and count slowly to 30. Make sure that the whole transdermal patch is in contact with your skin, especially at the edges.

You should wear the patch for seven days. Provided that you have applied the patch correctly, there is little risk of it coming off. If the edges of the patch begin to peel off, they may be taped down with a suitable skin tape. You may shower, bathe or swim whilst wearing it.

Do not expose the patch to extreme heat (e.g. heating pads, electric blanket, heat lamps, sauna, hot tubs heated water beds, hot water bottle etc.) as this may lead to larger quantities of the active ingredient being absorbed into the blood than normal. External heat may also prevent the patch from sticking properly. If you have a high temperature this may alter the effects of Panitaz patches (see “Warnings and precautions” section above).

In the unlikely event that your patch falls off before it needs changing, do not use the same patch again. Stick a new one on straight away (see “Changing the transdermal patch” below).

• Take the old patch off.
• Fold it in half with the sticky side inwards.
• Open and take out a new patch. Use the empty sachet to dispose of the old patch. Now discard the sachet safely.
• Even used patches contain some active ingredient that may harm children or animals, so make sure your used patches are always kept out of the sight and reach of them.
• Stick a new patch on a different appropriate skin site (as described above). You should not apply a new patch to the same site for 3-4 weeks.
• Remember to change your patch at the same time of day. It is important that you make a note of the time of day.

Your doctor will tell you how long you should be treated with the Panitaz patch. Do not stop treatment without consulting a doctor, because your pain may return and you may feel unwell (see also “If you stop using Panitaz” below).

If you feel that the effect of the Panitaz patch is too weak or too strong, talk to your doctor or pharmacist.

As soon as you discover that you have used more patches than you should, remove all patches and call your doctor or hospital straight away. People who have taken an overdose may feel very sleepy and sick. They may also have breathing difficulties or lose consciousness and may need emergency treatment in hospital. When seeking medical attention make sure that you take this leaflet and any remaining patches with you to show to the doctor.

Stick a new patch on as soon as you remember. Also make a note of the date, as your usual day of changing may now be different. If you are very late changing your patch, your pain may return. In this case, please contact your doctor.

Do not apply additional patches to make up for the forgotten application.

Do not suddenly stop using this medicine. If you want to stop using this medicine, discuss this with your prescriber 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 stop using Panitaz patches too soon or you interrupt your treatment your pain may return.

The pain relieving effect of Panitaz patch is maintained for some time after removal of the patch. You should not start another opioid analgesic (strong painkiller) within 24 hours after removal of the patch.

If you notice any of the following signs whilst using Panitaz, it could be a sign that you have become addicted

• you need to take the medicine for longer than advised by your prescriber
• you feel you need to use more than the recommended dose
• you are using the medicine for reasons other than prescribed
• when you stop taking the medicine you feel unwell, and you feel better once taking the medicine again.

If you notice any of these signs, it is important to talk to your prescriber.
