Can you take citalopram and cocodamol together?

No, you're safe. Citalopram is pretty selective for serotonin receptors and codeine for the opiate receptors. And the paracetamol is the co-codamol is pretty benign. The only thing I can think of is that back when I took citalopram for a little while, it was a little sedating, and theoretically the codeine could add to that, but the sedation from both is pretty weak. If you go to drugs.com you can check interactions in the future. Stay safe :)
