How does our body deal with alcohol and medicines?

It is usually our liver that processes medicines and it also processes alcohol.  If our liver has to deal with both at the same time it can slow the processing down for either alcohol or the medicine.  This can make the effects of one of them more pronounced.  Toxic levels of the medicine would be harmful to the body.  Alcohol may also make medicines less effective or not effective at all.

Paracetamol in excessive doses can cause liver damage.  The combination of paracetamol and alcohol is even more likely to cause liver damage and in some cases has lead to the need for a liver transplant.
