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).

Why this happens
Both tramadol and venlafaxine increase the levels of serotonin in the brain. When used together, these effects add up, potentially leading to dangerously high levels. Additionally, both drugs can lower the 'seizure threshold', making it easier for the brain to experience a seizure.
What you should do
You should speak to your doctor before taking these medicines together. They may prefer to prescribe an alternative painkiller or antidepressant. If your doctor decides you must take both, they will monitor you closely. Seek immediate medical help if you experience high fever, shivering, severe muscle stiffness, or confusion.
