Warnings and precautions
Consult your doctor before starting to take Clanderon
- If you are taking other medications that contain paracetamol or tramadol;
- If you have liver problems or liver disease, or if you notice that your eyes or skin turn yellow. This may be indicative of jaundice or problems with your bile ducts;
- If you have kidney problems;
- If you have severe respiratory difficulties, for example asthma or severe lung problems;
- If you are epileptic or have had seizures or convulsions;
- If you suffer from depression and are taking antidepressants, as some may interact with tramadol (see "Other medications and Clanderon").
- If you have recently experienced head trauma, shock or intense headaches associated with vomiting;
- If you have dependence on any other medication used for pain relief, for example morphine;
- If you are taking other medications for pain relief that contain buprenorphine, nalbuphine or pentazocine;
- If you are to be anesthetized. Inform your doctor or dentist that you are using Clanderon.
If any of these problems occur while taking Clanderon, inform your doctor. He/she will decide if you should continue taking this medication.
Respiratory problems related to sleep
Clanderon may cause respiratory problems related to sleep, such as central sleep apnea (pause in breathing during sleep) and sleep-related hypoxemia (low oxygen levels in the blood). These symptoms may include pause in breathing during sleep, nocturnal awakening due to difficulty breathing, difficulty maintaining sleep or excessive daytime somnolence. If you or someone else observes these symptoms, consult your doctor. Your doctor may consider reducing the dose.
There is a weak risk that you may experience a serotonin syndrome that can occur after taking tramadol in combination with certain antidepressants or tramadol monotherapy.
Consult your doctor immediately if you experience any of the symptoms associated with this serious syndrome (see section 4 "Possible side effects").
Tramadol is metabolized in the liver by an enzyme. Some people have a variation of this enzyme and this may affect each person differently. In some people, it may be possible to achieve insufficient pain relief, while others may be more likely to experience severe side effects. If you notice any of the following side effects, stop taking this medication and consult your doctor immediately: slow or shallow breathing, confusion, somnolence, constricted pupils, general malaise or vomiting, constipation, loss of appetite.
Tolerance, dependence and addiction
This medication contains tramadol, which is an opioid medication. Repeated use of opioids can make the medication less effective (you become tolerant of it, known as tolerance). Repeated use of tramadol/paracetamol can also cause dependence, abuse and addiction, which can lead to a potentially fatal overdose. The risk of these side effects may increase with a higher dose and longer duration of use.
Dependence or addiction can make you feel like you no longer control the amount of medication you need to take or the frequency with which you need to take it.
The risk of becoming dependent or addicted to tramadol/paracetamol varies from person to person. You may have a higher risk of becoming dependent or addicted to tramadol/paracetamol if:
If you notice any of the following signs while taking tramadol/paracetamol, it could be a sign that you have become dependent or addicted:
If you observe any of these signs, talk to your doctor to determine the best course of treatment for you, including when it is appropriate to stop taking it and how to do it safely (see section 3, If you stop taking tramadol/paracetamol).
Children and adolescents
Use in children with respiratory problems.
Tramadol should not be used in children with respiratory problems, as the symptoms of tramadol toxicity may worsen in these children.
Inform your doctor or pharmacist if you experience any of the following symptoms while taking Clanderon:
Extreme fatigue, loss of appetite, severe abdominal pain, nausea, vomiting or low blood pressure. This may indicate that you have adrenal insufficiency (low cortisol levels). If you experience any of these symptoms, inform your doctor, who will decide if you should take a hormone supplement.
Other medications and Clanderon
Inform your doctor or pharmacist if you are taking, have taken recently or may need to take any other medication.
Important: This medication contains paracetamol and tramadol. Inform your doctor if you are takingany other medication that contains paracetamol or tramadol,so as not to exceed the maximum daily dose.
Clanderonshould not be takenwith monoamine oxidase inhibitors (MAOIs) (see "Do not take Clanderon").
Do not use Clanderon if you are being treated with:
The risk of side effects increases:
The effectiveness of Clanderon may be altered if you are also taking:
- metoclopramide, domperidone or ondansetron (medications for the treatment of nausea and vomiting),
- cholestyramine (medication that reduces cholesterol in the blood).
Your doctor will know which medications are safe to use with Clanderon.
Taking Clanderon with food, drinks and alcohol
Clanderon may make you feel drowsy. Alcohol may make you feel more drowsy, so it is recommended not to drink alcohol while taking Clanderon.
Pregnancy, breastfeeding and fertility
If you are pregnant or breastfeeding, or if you think you may be pregnant, consult your doctor or pharmacist before using this medication.
Due to the fact that Clanderon contains tramadol, it is not recommended to take this medication during pregnancy or breastfeeding. If you become pregnant during treatment with Clanderon, consult your doctor before taking the next tablet.
Breastfeeding
Tramadol is excreted in breast milk. For this reason, you should not take Clanderon more than once during breastfeeding, or, if you take Clanderon more than once, you should stop breastfeeding.
Based on human experience, it is not suggested that tramadol affects fertility in men and women. There are no data available on the combination of tramadol and paracetamol in fertility.
Driving and operating machinery
Ask your doctor if you can drive or operate machinery during treatment with tramadol/paracetamol. It is essential to observe how this medication affects you before driving or operating machinery. Do not drive or operate machinery if you feel drowsy, dizzy, have blurred vision or double vision, or have difficulty concentrating. Be particularly careful at the start of treatment, after increasing the dose, after changing the formulation, and/or when taking it concomitantly with other medications.
Clanderon contains sodium
This medication contains 178.11 mg of sodium (main component of table salt/for cooking) in each effervescent tablet. This is equivalent to 9.11% of the maximum daily sodium intake recommended for an adult.
Consult your doctor or pharmacist if you need 2 or more effervescent tablets daily for a prolonged period, especially if you have been recommended a low-sodium diet.
Follow exactly the administration instructions of this medication indicated by your doctor. In case of doubt, consult your doctor or pharmacist again.
Before starting treatment and regularly during it, your doctor will explain what you can expect from the use of tramadol/paracetamol, when and for how long you should take it, when you should contact your doctor and when you should interrupt it (see also section 2).
You should take Clanderon for the shortest time possible.
Use in children under 12 years is not recommended.
The dose should be adjusted to the intensity of the pain and your individual sensitivity. Normally, the lowest dose possible that produces pain relief should be used.
Unless your doctor prescribes something else, the recommended starting dose for adults and adolescents over 12 years is 2 effervescent tablets.
If necessary, you can increase the dose as recommended by your doctor. The shortest interval between doses should be at least 6 hours.
Do not take more than 8 Clanderon tablets per day.
Do not take Clanderon more frequently than your doctor has indicated.
Older patients
In elderly patients (over 75 years), the elimination of tramadol may be slow. If this is your case, your doctor may recommend prolonging the dosing intervals.
Patients with liver or kidney insufficiency/patients on dialysis
If you have a severe liver or kidney disease, treatment with tramadol/paracetamol is not recommended. If you have moderate liver or kidney disease, your doctor may prolong the dosing intervals.
Administration form
The effervescent tablets are administered orally.
The effervescent tablets are taken dissolved in a glass of water. Before ingesting the medication, the effervescence must cease.
If you estimate that the effect of Clanderon is too strong (e.g., you feel very drowsy or have difficulty breathing) or too weak (e.g., you do not have adequate pain relief), inform your doctor.
If you take more Clanderon than you should
If you have taken more Clanderon than you should, even if you feel well, consult your doctor or pharmacist immediately, as there is a risk of severe liver damage that will only become apparent later.
In case of overdose or accidental ingestion, go immediately to a medical center or call the Toxicological Information Service, phone 91 562 04 20 indicating the medication and the amount taken.
If you forgot to take Clanderon
If you forgot to take a dose of Clanderon, it is likely that the pain will recur. Do not take a double dose to compensate for the missed doses, simply continue taking the tablets as usual.
If you interrupt the treatment with Clanderon
You should not stop taking this medication suddenly unless your doctor tells you to. If you want to stop taking your medication, talk to your doctor first, especially if you have been taking it for a long time. Your doctor will inform you when and how to interrupt it, which can be done by gradually reducing the dose to reduce the likelihood of unnecessary adverse effects (withdrawal symptoms).
If you have any other doubts about the use of this medication, ask your doctor or pharmacist.
