Warnings and precautions
Tramadol is transformed in the liver by an enzyme. Some people have a variation of this enzyme, and this can affect each person differently. In some people, sufficient pain relief may not be achieved, while others are more likely to suffer from serious side effects. If you notice any of the following side effects, you should stop taking this medication and consult a doctor immediately: slow or shallow breathing, confusion, drowsiness, constricted pupils, general malaise, or vomiting, constipation, loss of appetite.
Seizures have been reported in patients taking tramadol at the recommended dose. The risk may increase when the dose of tramadol exceeds the recommended daily dose limit (400 mg).
Tolerance, dependence, and addiction
This medication contains tramadol, which is an opioid medication. Repeated use of opioids can make the drug less effective (the body gets used to it, which is known as pharmacological tolerance). Repeated use of tramadol can also lead to dependence, abuse, and addiction, which could result in a potentially fatal overdose. The risk of these side effects may be greater with a higher dose and longer use.
Dependence or addiction can cause a feeling of lack of control over the amount of medication you need to use or how often you need to use it.
The risk of dependence or addiction varies from person to person. The risk of becoming dependent on or addicted to tramadol may be greater if:
If you observe any of the following symptoms while using tramadol, it could be a sign of dependence or addiction:
If you notice any of these signs, consult your doctor to determine the best treatment option for you, when it is appropriate to stop the medication, and how to do it safely (see section 3, if you interrupt treatment with Tramadol Retard Combix).
Respiratory disorders related to sleep
Tramadol Retard Combix may cause respiratory disorders related to sleep, such as sleep apnea (pauses in breathing during sleep) and sleep-related hypoxemia (low oxygen level in the blood). Symptoms may include pauses in breathing during sleep, nighttime awakenings due to shortness of breath, difficulty maintaining sleep, or excessive daytime sleepiness. If you or someone else observes these symptoms, contact your doctor. Your doctor may consider reducing the dose.
Talk to your doctor or pharmacist if you experience any of the following symptoms while taking Tramadol Retard Combix:
Extreme fatigue, loss of appetite, severe abdominal pain, nausea, vomiting, or low blood pressure. They can be indicators of adrenal insufficiency (low cortisol levels). If you have these symptoms, contact your doctor, who will decide if you need to take hormonal supplements.
Also, inform your doctor if any of these problems occur during treatment with Tramadol Retard Combix or if you have had them before.
There is a slight risk that you may experience a serotonin syndrome that can occur after taking tramadol in combination with certain antidepressants or tramadol alone. Consult a doctor immediately if you present any of the symptoms related to this serious syndrome (see section 4 "Possible side effects").

Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication.
There is very little information regarding the safety of tramadol during human pregnancy. Therefore, you should not take Tramadol Retard Combix if you are pregnant.
Chronic use during pregnancy can lead to withdrawal syndrome in newborns.
Generally, the use of tramadol is not recommended during breastfeeding. Tramadol is excreted in breast milk. For this reason, you should not take Tramadol Retard Combix more than once during breastfeeding, or if you take Tramadol Retard Combix more than once, you should interrupt breastfeeding.
Driving and using machines
Ask your doctor if you can drive or use machines during treatment with Tramadol Retard Combix. It is essential that before driving or using machines, you observe how this medication affects you. Do not drive or use machines if you feel sleepy, dizzy, have blurred vision, or double vision, or have difficulty concentrating. Be careful when administering it in combination with other medications.
Follow the instructions for administration of Tramadol Retard Combix indicated by your doctor.
Consult your doctor or pharmacist if you have doubts.
Before starting treatment and regularly during treatment, your doctor will also explain what you can expect from the use of Tramadol Retard Combix, when and for how long you should use it, when you should contact your doctor, and when you should stop using it (see also section 2).
The dose should be adjusted according to the intensity of the pain and individual sensitivity to pain. In general, the lowest analgesic dose should be taken.
Unless your doctor has given you different instructions, the usual dose is:
Adults and adolescents over 12 years
One Tramadol Retard Combix 100 mg prolonged-release tablet twice a day (equivalent to 200 mg of tramadol hydrochloride per day), preferably in the morning and at night.

Tramadol Retard Combix should not be administered for longer than strictly necessary.
If you require prolonged treatment, your doctor will monitor you at short and regular intervals (if necessary, with interruptions in treatment) to determine if you should continue treatment with Tramadol Retard Combix and at what dose.
If you think the action of this medication is too strong or too weak, inform your doctor or pharmacist.
If you take more Tramadol Retard Combix than you should
If you have taken more Tramadol Retard Combix than you should by mistake, it will generally not have negative effects. You should take the next dose as prescribed.
After taking very high doses, it can cause constricted pupils, vomiting, decreased blood pressure, increased heart rate, collapse, decreased level of consciousness up to coma (deep unconsciousness), seizures, and difficulty breathing that can lead to respiratory arrest. In such a case, contact a doctor immediately.
If you forget to take Tramadol Retard Combix
If you forget to take the tablets, it is likely that the pain will return. Do not take a double dose to make up for the forgotten doses; simply continue treatment as indicated by your doctor.
If you interrupt treatment with Tramadol Retard Combix
You should not stop taking this medication suddenly unless your doctor indicates it. 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 side effects (withdrawal symptoms).
Generally, no undesirable effects occur when finishing treatment with Tramadol Retard Combix. However, in rare cases, when some people who have been taking Tramadol Retard Combix for some time stop taking it suddenly, they may feel unwell. They may feel agitated, anxious, nervous, or trembly. They may feel hyperactive, have difficulty sleeping, or have gastrointestinal or intestinal disorders. Very few people may have panic attacks, hallucinations, unusual perceptions such as itching, tingling, and numbness, and ringing in the ears (tinnitus). Rarely, other unusual symptoms of the central nervous system have been seen, such as confusion, delirium, distorted perception of one's own personality (depersonalization), and altered perception of reality (derealization) and persecution delusions (paranoia). If you present any of these symptoms after interrupting the use of Tramadol Retard Combix, please consult your doctor. If you have any doubts about the use of this medication, consult your doctor or pharmacist.
