Taking these two medicines together significantly increases the risk of a rare but serious condition called 'serotonin syndrome'. This occurs 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 twitching, or diarrhoea. In rare cases, this combination can also increase the risk of having a seizure (a fit).

Video picks for Läkemedelsinteraktioner
It is not recommended that you take tramadol och venlafaxine together as both medicines increase the levels of serotonin in the brain, which can raise the risk of a serious reaction called serotonin syndrome.
Additionally, both drugs can lower the 'seizure threshold', making it easier for the brain to experience a seizure.

Viktiga försiktighetsåtgärder
Tillbaka till innehållSerotonin syndrome
Taking these two medicines together significantly increases the risk of serotonin syndrome, a potentially life-threatening condition. Seek immediate medical help if you experience high fever, agitation, confusion, shivering, or rapid muscle contractions.
Suicidal thoughts and self-harm
Antidepressants like venlafaxine can increase thoughts of self-harm or suicide, particularly when first starting the treatment or changing the dose. Monitor your mood closely and tell someone you trust or seek medical help immediately if your mood worsens.
Seizures (fits)
Both medicines can lower the seizure threshold. Taking them together increases the risk of having a fit, especially if you have a history of epilepsy or are taking other medicines that increase seizure risk.
Breathing problems or asthma
Tramadol can cause dangerous breathing difficulties, especially if you have existing lung conditions or asthma. Seek immediate medical help if you experience slow or shallow breathing.
Bleeding risk
Venlafaxine can increase your risk of bleeding, particularly from the gut. This risk is much higher if you also take aspirin, NSAIDs (like ibuprofen or naproxen), or blood-thinning medicines.

Varningar för mat och dryck
Tillbaka till innehållAlkohol
It is best to avoid or strictly limit alcohol while taking these medicines. Combining alcohol with tramadol or venlafaxine increases the risk of severe drowsiness, dizziness, and breathing difficulties. It can also increase the risk of liver damage.
Caffeine (Coffee, Tea, Energy Drinks)
Venlafaxine can increase the levels of caffeine in your blood, and caffeine can increase your blood pressure. This may lead to feeling jittery, anxious, or having a racing heart. Limit your intake of caffeine-containing drinks.

Can I take Aspirin and Furosemide together?
Taking aspirin and furosemide together can make the furosemide (water tablet) less effective at removing excess fluid from your body. Additionally, at high doses of aspirin, there is an increased risk of kidney problems and a build-up of aspirin in your blood, which can lead to side effects like ringing in the ears (tinnitus).
