Can I take Citalopram and Co codamol together?

Why this happens

Both drugs affect a chemical in the brain called serotonin; when levels get too high, it causes side effects. Citalopram can also block the liver enzyme (CYP2D6) needed to convert codeine into its active form (morphine), potentially making the painkiller less effective. Both drugs also have 'depressant' effects on the central nervous system, which increases sleepiness.

What you should do

You can take these together if your doctor has prescribed them, but you should be aware of the signs of serotonin syndrome (such as shivering, diarrhoea, confusion, muscle stiffness, or a high temperature). If you feel very drowsy or find the co-codamol isn't helping your pain, speak to your GP. Avoid alcohol while taking these medicines.

Important precautions

Serotonin-Syndrom

Taking these medicines together increases the risk of serotonin syndrome, a potentially life-threatening condition. Seek immediate medical help if you experience agitation, hallucinations, fast heartbeat, or severe muscle stiffness.

Heart rhythm disorders (Long QT syndrome)

Citalopram can affect your heart rhythm. You must not take it if you have a pre-existing heart rhythm problem or are taking other medicines that affect the heart's electrical activity.

Food and drink warnings

Alkohol

You should avoid or strictly limit alcohol while taking these medicines. Both citalopram and the codeine in co-codamol can cause drowsiness and dizziness. Alcohol significantly increases these effects, making you feel much sleepier and increasing the risk of falls or accidents. In the case of co-codamol, alcohol also increases the risk of dangerous breathing problems.
