Tramadol hydrochloride - the active substance in Tramadol belongs to a class of medicines called opioids, which are pain relievers. This medicine has been prescribed to you and should not be given to anyone else.
Tramadol is used for the treatment of moderate to severe pain.
Opioids can cause addiction and you may get withdrawal symptoms if you stop taking it suddenly.
Your prescriber should have explained how long you will be taking it for and when it is appropriate to stop, how to do this safely.
Talk to your doctor or pharmacist before taking Tramadol, if:
There is a small risk that you may experience a so-called serotonin syndrome that can occur after having taken tramadol in combination with certain antidepressants or tramadol alone. Seek medical advice immediately if you have any of the symptoms related to this serious syndrome (see section 4 ‘Possible side effects’).
Tolerance, dependence, and addiction This medicine contains tramadol 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 tramadol 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 tramadol if:
If you notice any of the following signs whilst taking tramadol, it could be a sign that you have become dependent or addicted:
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 Tramadol).
Tramadol is transformed in the liver by an enzyme. Some people have a variation of this enzyme and this can affect people in different ways. In some people, they may not get enough pain relief but other people are more likely to get serious side effects. If you notice any of the following side effects, you must stop taking this medicine and seek immediate medical advice: slow or shallow breathing, confusion, sleepiness, small pupils, feeling or being sick, constipation, lack of appetite.
Sleep-related breathing disorders
Tramadol belongs to the group of opioids. Opioids can cause sleep-related breathing disorders, for example central sleep apnoea (shallow/pause of breathing during sleep) and sleep-related hypoxemia (low oxygen level in the blood).
The risk of experiencing central sleep apnea is dependent on the dose of opioids. Your doctor may consider decreasing your total opioid dosage if you experience central sleep apnea.
Epileptic fits have been reported in patients taking tramadol at the recommended dose level. The risk may be increased when doses of tramadol exceed the recommended upper daily dose limit (400 mg).
Taking this medicine regularly, particularly for a long time, can lead to addiction. Your prescriber should have explained how long you will be taking 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 prescriber 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 prescriber 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.
Talk to your doctor or pharmacist if you experience any of the following symptoms while taking Tramadol:
Extreme fatigue, lack of appetite, severe abdominal pain, nausea, vomiting or low blood pressure. This may indicate that you have adrenal insufficiency (low cortisol levels). If you have these symptoms, contact your doctor, who will decide if you need to take hormone supplement.
Use in children with breathing problems: Tramadol is not recommended in children with breathing problems, since the symptoms of tramadol toxicity may be worse in these children.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
Do not take Tramadol at the same time as medicines called “monoamine oxidase inhibitors” or MAOIs (which are used to treat e.g. depression), or if you have taken MAOIs in the past 2 weeks.
The pain-relieving effect of Tramadol may be reduced and the length of time it acts may be shortened if you also take medicines containing:
Your doctor will tell you whether you should take Tramadol, and which dose.

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 taking this medicine.
Do not take Tramadol if you are pregnant or think you might 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 Tramadol during pregnancy, your baby may become dependent and experience withdrawal symptoms after the birth which may need to be treated.
Do not take Tramadol while you are breastfeeding as tramadol passes into breast milk and will affect your baby.
Based on human experience tramadol is suggested not to influence female or male fertility.
