Taking these two medicines together can lead to a rare but very serious condition called 'serotonin syndrome'. This happens when there is too much of a chemical called serotonin in your brain. Symptoms can include feeling very agitated, confused, or shaky, as well as sweating, a fast heartbeat, muscle stiffness, or diarrhoea. In extreme cases, it can cause seizures. Additionally, fluoxetine can make tramadol less effective at relieving your pain.

Pourquoi cela se produit
Both fluoxetine and tramadol increase the levels of serotonin in the brain. When used together, these effects add up and can reach dangerous levels. Furthermore, fluoxetine blocks a specific enzyme in the liver (CYP2D6) that is responsible for converting tramadol into its active, pain-killing form. This means the tramadol may not work as well for your pain, while the risk of side effects actually increases.
Ce que vous devriez faire
Retour au sommaireYou should speak to your doctor before taking these two medicines together. They may prefer to prescribe an alternative painkiller that does not interact with your antidepressant. If your doctor decides you must take both, they will monitor you closely. Seek urgent medical help if you experience extreme confusion, shivering, very high fever, or muscle twitching.

Précautions importantes
Retour au sommaireSyndrome sérotoninergique
Prendre ces médicaments ensemble augmente considérablement le risque de syndrome sérotoninergique, une condition potentiellement mortelle. Consultez immédiatement un médecin si vous ressentez une forte fièvre, de l'agitation, de la confusion ou des contractions musculaires.
Under 25 years old suicidal thoughts
In children and young adults, fluoxetine can occasionally increase thoughts of self-harm or suicide when first started; you must be closely monitored by family or a doctor during the first few weeks.
Epilepsy or Seizures
Tramadol can trigger seizures, even at normal doses. This risk is much higher if you have a history of epilepsy or are taking antidepressants like fluoxetine.
Breathing Problems
Tramadol is an opioid and can cause dangerous breathing difficulties. It must be used with extreme caution if you have asthma or any chronic lung condition.
Bleeding disorders or use of blood thinners
Fluoxetine can increase your risk of bleeding, especially if you are already taking medicines that thin the blood (like warfarin) or non-steroidal anti-inflammatory drugs (like ibuprofen).
Diabète
Fluoxetine can affect your blood sugar levels. You may need to monitor your blood glucose more closely as your dose of insulin or antidiabetic medicine might need adjusting.
Avertissements sur la nourriture et les boissons
Retour au sommaireAlcool
It is best to avoid or strictly limit alcohol while taking these medicines. Combining alcohol with fluoxetine or tramadol can significantly increase drowsiness, dizziness, and the risk of breathing difficulties. Both medicines, particularly when combined with alcohol, can impair your coordination and judgment. Additionally, combining alcohol with certain antidepressants can increase the risk of liver damage.
Caféine (Café, thé, boissons énergisantes)
Fluoxetine can increase the effects of caffeine in your body. This may lead to feeling jittery, anxious, or having difficulty sleeping. You may need to limit your caffeine intake.
