Taking paracetamol and tramadol together is generally safe and is a very common way to manage moderate to severe pain. In fact, many doctors prescribe them together, and some tablets even contain both medicines in one pill. However, because both drugs work to reduce pain, taking them together increases the risk of side effects like drowsiness, dizziness, or feeling sick (nausea). There is also a very small risk of a rare but serious condition called serotonin syndrome, though this is much more likely if you are also taking antidepressants.

Why this happens
These drugs work in different ways to block pain. Paracetamol works mainly in the central nervous system to reduce pain signals, while tramadol is an opioid-type medicine that changes how your brain and nervous system respond to pain. Because they use different 'pathways' to stop pain, they can be used together for a stronger effect (this is called an additive effect). Both drugs are processed by the liver, but at normal doses, they do not interfere with each other's metabolism.
What you should do
It is safe to take these together if your doctor has advised it, but you must never exceed the maximum daily dose for either medicine. For paracetamol, this is usually 4000mg (eight 500mg tablets) in 24 hours. Be careful when checking other medicines (like cold and flu remedies) to ensure they don't also contain paracetamol. If you feel excessively sleepy, dizzy, or have trouble breathing, stop taking the tramadol and seek medical advice. Avoid drinking alcohol while taking this combination.

Important precautions
Accidental Overdose Risk
Many cold and flu remedies or other painkillers also contain paracetamol. Taking more than one product containing paracetamol can lead to fatal liver damage. Always check the ingredients of all medicines before taking them together.
Epilepsy or Seizure Risk
Tramadol can increase the risk of having a fit (seizure), even in people who have never had one before. This risk is higher if you have epilepsy or are taking certain antidepressants.
Breathing Problems (Asthma/COPD)
Tramadol can dangerously slow down your breathing. You must not take it if you have severe breathing difficulties or are having an acute asthma attack.
Food and drink warnings
Alcohol
You must avoid drinking alcohol while taking tramadol. Alcohol increases the sedative effects of tramadol, which can lead to dangerous levels of drowsiness, breathing difficulties, and a risk of unconsciousness.

Treatment and medication
Can I take Azithromycin and Terbutaline together?
Taking azithromycin and terbutaline together may increase the risk of developing an irregular heart rhythm. While this is rare, it can be serious. Symptoms to watch out for include heart palpitations (a fluttering feeling in the chest), dizziness, fainting, or sudden shortness of breath.

Treatment and medication
Can I take Fluoxetine and Tramadol together?
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.
