Leaflet: information for the user
Oxicodona/Naloxona Cinfa20 mg/10 mg prolonged-release EFG tablets
Oxicodone hydrochloride / Naloxone hydrochloride
Read this leaflet carefully before you start to take this medicine, because it contains important information for you.
Oxicodona/naloxona cinfa is a prolonged-release tablet, meaning that its active ingredients are released over a prolonged period of time. Its action lasts 12 hours.
This medication is intended for use only in adults.
Pain relief
You have been prescribed oxicodona/naloxona for the treatment of intense pain, which can only be adequately treated with opioid analgesics. Hydrochloride of naloxone is added to counteract constipation.
How these tablets work for pain relief
These tablets contain as active ingredients hydrochloride of oxicodona and hydrochloride of naloxona. Hydrochloride of oxicodona is responsible for the analgesic effect of the medication. It is a potent analgesic of the opioid group. The second active ingredient of this medication, hydrochloride of naloxona, has the function of counteracting constipation. Intestinal dysfunction (e.g. constipation) is a common adverse effect of treatment with opioid analgesics.
Do not take oxicodona/naloxona cinfa:
Warnings and precautions
Consult your doctor or pharmacist before starting to take oxicodona/naloxona cinfa:
Contact your doctor if you have severe upper abdominal pain that may extend to the back, nausea, vomiting or fever, as these may be symptoms associated with pancreatitis and biliary tract system inflammation.
Inform your doctor if you have had any of these diseases in the past. Also inform your doctor if you develop any of them during treatment with oxicodona/naloxona.
Tolerance, dependence and addiction
This medicine contains oxicodona, which is an opioid medication. Repeated use of opioid analgesics may make the drug less effective (you become accustomed to it, known as tolerance). Repeated use of oxicodona/naloxona may cause dependence, abuse and addiction, which may lead to an overdose that puts your life at risk. The risk of these side effects may increase with a higher dose and longer duration of use.
Dependence or addiction may make you feel that you no longer have control over the amount of medication you need to take or how often you need to take it. You may feel that you need to continue taking the medication, even when it no longer helps to relieve your pain.
The risk of becoming dependent or addicted varies from person to person. You may have a higher risk of becoming dependent or addicted to oxicodona/naloxona:
-if you or a family member has a history of alcohol, prescription medication or illicit substance abuse (“addiction”).
-if you smoke.
-if you have ever had problems with your mood (depression, anxiety or personality disorder) or have received treatment from a psychiatrist for other mental health conditions.
If you notice any of the following signs while taking oxicodona/naloxona, it could be a sign that you have become dependent or addicted.
-You need to take the medication for longer than recommended by your doctor.
-You need to take more doses than recommended.
-You are using the medication for reasons other than those prescribed, for example, “to stay calm” or “to help you sleep”.
-You have made repeated and unsuccessful attempts to stop or control the use of the medication.
-You do not feel well when you stop taking the medication and feel better once you take it again (“withdrawal symptoms”).
If you notice any of these signs, talk to your doctor to analyze the best treatment for you, including when it is appropriate to stop taking it and how to do it safely (see section 3, If you interrupt treatment with oxicodona/naloxona).
The most severe result of opioid overdose is respiratory depression (slow and shallow breathing). This may also cause a decrease in oxygen concentration in the blood, which may cause fainting, etc..
Respiratory disorders related to sleep
This medicine contains oxicodona, which is an opioid, and may produce dependence and/or addiction. |
Oxicodona/naloxona may cause respiratory disorders related to sleep such as sleep apnea (pause in breathing during sleep) and sleep-related hypoxemia (low oxygen levels in the blood). Symptoms may include pauses in breathing during sleep, nocturnal awakenings due to difficulty breathing, difficulty maintaining sleep or excessive daytime sleepiness. If you or someone else observes these symptoms, consult your doctor. Your doctor may consider reducing the dose.
Swallow the prolonged-release tablet whole, so that it does not affect the slow release of hydrochloride of oxicodona from the tablet. Do not break, chew or crush the tablets. If you do, your body may absorb a potentially fatal dose of hydrochloride of oxicodona (see section 3 “If you take more oxicodona/naloxona cinfa than you should”).
If you experience intense diarrhea at the beginning of treatment, it may be due to the effect of naloxona. It may be a sign that intestinal function is normalizing. This diarrhea may occur in the first 3 to 5 days of treatment. If it persists after that period of 3 to 5 days, or if you are concerned, contact your doctor.
If you have been receiving another opioid, you may experience withdrawal symptoms shortly after starting treatment with oxicodona/naloxona, for example, restlessness, sweating and muscle pain. If you experience any of these symptoms, you may need special monitoring by your doctor.
You may develop tolerance if you use oxicodona/naloxona for a long time.This means that you will need a higher dose to achieve the desired effect. Long-term use of oxicodona/naloxona may also produce physical dependence. Withdrawal symptoms may appear if treatment is stopped suddenly (restlessness, sweating, muscle pain). If you stop needing treatment, you should reduce the daily dose gradually, consulting with your doctor.
The active ingredient hydrochloride of oxicodona alone has the same abuse characteristics as other potent opioids (potent analgesics). It may create psychological dependence. Medicines containing hydrochloride of oxicodona should be avoided in patients who have a history of abuse of alcohol, drugs or medications.
Inform your doctor if you have cancer associated with peritoneal metastases or onset of obstruction in the intestine in advanced stages of digestive or pelvic cancer.
If you need to undergo surgery, inform the doctors that you are receiving treatment with oxicodona/naloxona.
Like other opioids, oxicodona may affect normal hormone production in the body such as cortisol or sex hormones, especially if you take high doses for long periods of time. If you notice persistent symptoms such as discomfort (including vomiting), loss of appetite, fatigue, weakness, dizziness, changes in menstrual cycle, impotence, infertility or decreased libido, consult your doctor to monitor your hormone levels.
You may observe remnants of the prolonged-release tablet in the feces. Do not be alarmed, as the active principles (hydrochloride of oxicodona and hydrochloride of naloxona) have already been released in the stomach and intestine, and have been absorbed by your body.
Incorrect use of oxicodona/naloxona cinfa
Oxicodona/naloxona is not a treatment for withdrawal syndrome.
Do not abuse oxicodona/naloxona, especially if you have a substance abuse problem. If you are addicted to substances such as heroin, morphine or methadone, you may experience severe withdrawal symptoms if you misuse oxicodona/naloxona, as it contains naloxona. These symptoms may worsen existing withdrawal symptoms.
Do not dissolve the prolonged-release tablets of oxicodona/naloxona to inject them (for example, into a blood vessel). The reason is that they contain talc, which may cause local tissue destruction (necrosis) and pulmonary tissue alterations (pulmonary granuloma). This incorrect use may also have other serious consequences and even cause death.
The use of oxicodona/naloxona may give positive results in drug tests.The use of oxicodona/naloxona as a doping agent may put your health at risk.
Other medicines and oxicodona/naloxona cinfa
Inform your doctor or pharmacist if you are taking, have taken recently or may need to take any other medicine.
The concomitant use of opioids, including hydrochloride of oxicodona and sedative medications such as benzodiazepines or related medications, increases the risk of drowsiness, difficulty breathing (respiratory depression), coma and may put your life at risk. Due to this, concomitant use should only be considered when other treatment options are not possible.
However, if your doctor prescribes oxicodona/naloxona together with sedative medications, your doctor should limit the dose and duration of concomitant treatment.
Inform your doctor of all sedative medications you are taking and follow the recommended doses closely. It may be helpful to inform friends or family members who are aware of the signs and symptoms mentioned above. Contact your doctor when you experience these symptoms. Some examples of sedative medications or related medications are:
If you take these tablets at the same time as other medications, the effects of the tablets or the other medications described below may change. Inform your doctor if you are taking:
No interaction is expected between oxicodona/naloxona and paracetamol, acetylsalicylic acid or naltrexona.
The risk of side effects increases if you use antidepressants (such as citalopram, duloxetine, escitalopram, fluoxetine, fluvoxamine, paroxetine, sertraline, venlafaxine). These medications may interact with oxicodona and you may experience symptoms such as involuntary muscle contractions, agitation, excessive sweating, tremor, exaggerated reflexes, increased muscle tension and body temperature above 38 °C. Contact your doctor if you experience these symptoms.
Taking oxicodona/naloxona cinfa with food, drinks and alcohol
Drinking alcohol while taking oxicodona/naloxona may make you feel more drowsy or increase the risk of serious side effects such as shallow breathing with the risk of stopping breathing, and loss of consciousness. It is recommended not to drink alcohol while taking oxicodona/naloxona.
You should avoid drinking grapefruit juice while taking oxicodona/naloxona.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, consult your doctor or pharmacist before using this medicine.
Pregnancy
During pregnancy, oxicodona/naloxona should be avoided as much as possible. If used during prolonged periods of pregnancy, hydrochloride of oxicodona may cause withdrawal symptoms in the newborn. If hydrochloride of oxicodona is administered during delivery, the newborn may experience respiratory depression (slow and shallow breathing).
Breastfeeding
Stop breastfeeding during treatment with oxicodona/naloxona. Hydrochloride of oxicodona passes into breast milk. It is unknown whether hydrochloride of naloxona also passes into breast milk. Therefore, the risk to the infant cannot be ruled out, especially if the mother receives several doses of oxicodona/naloxona.
Driving and operating machines
Ask your doctor if you can drive or operate machines during treatment with oxicodona/naloxona. It is essential to observe how this medicine affects you before driving or operating machines. Do not drive or operate machines if you feel drowsy, dizzy, have blurred vision or double vision, or have difficulty concentrating. Be especially careful at the beginning of treatment, after increasing the dose, after changing the formulation and/or when taking it together with other medications.
Oxicodona/naloxona cinfa contains sodium
This medicine contains less than 1 mmol of sodium (23 mg) per tablet; it is essentially “sodium-free”.
Before starting treatment and periodically during treatment, your doctor will talk to you about what you can expect from the use of oxicodona/naloxona, when and for how long you should take it, when to contact your doctor and when to stop taking it (see also “If you interrupt treatment with oxicodona/naloxona”).
Oxicodona/naloxona cinfa is a prolonged-release tablet, which means that the active principles are released over a prolonged period of time. Its action lasts 12 hours.
You must swallow the prolonged-release tablet whole without affecting the slow release of hydrochloride oxicodona from the tablet.Do not break, crush, or chew the tablets.If you do, your body may absorb a potentially fatal dose of hydrochloride oxicodona (see section 3 “If you take more oxicodona/naloxona cinfa than you should”).
Unless your doctor tells you otherwise, the recommended dose is:
For pain treatment
Adults
The initial recommended dose is 10 mg of hydrochloride oxicodona / 5 mg of hydrochloride naloxona in prolonged-release tablets every 12 hours.
Your doctor will decide the dose ofoxicodona/naloxonayou should take per day and how to divide the total daily dose between the morning dose and the evening dose. Your doctor will also decide if you need to adjust the dose during treatment. Your dose will be adjusted to your level of pain and individual sensitivity. You should receive the minimum dose necessary to relieve pain. If you have already received treatment with opioids, the initial dose ofoxicodona/naloxonamay be higher.
The maximum daily dose is 160 mg of hydrochloride oxicodona and 80 mg of hydrochloride naloxona. If you need a higher dose, your doctor may prescribe more hydrochloride oxicodona without hydrochloride naloxona. However, the maximum daily dose of hydrochloride oxicodona should not exceed 400 mg. The beneficial effect of hydrochloride naloxona on intestinal activity may be affected if the dose of hydrochloride oxicodona is increased without increasing the dose of hydrochloride naloxona.
If you substitutethese tabletswith another opioid analgesic, it is likely that your intestinal function will worsen.
If you experience pain between two doses ofoxicodona/naloxona,you may need a rapid-acting analgesic. Oxicodona/naloxona is not a treatment for this case. Consult your doctor.
If you think the effect ofthese tabletsis too strong or too weak, consult your doctor or pharmacist.
