Interactions with other drugs

Alcohol interactions with other drugs
Alcohol is a drug that when taken in combination with other drugs – including medicines or illicit drugs, can lead to adverse effects. These occur because the two drugs interact in the body. Some individuals may choose to mix alcohol with other drugs whilst others may do so by accident or without knowledge of the risks. The effects on the body of mixing drugs (poly-drug use) can vary greatly across different people. The effects of mixing alcohol with other drugs can be unpredictable and dangerous.
What is a drug interaction?
It is when the effects of one drug alter the effects of another drug. The usual effects of a particular drug may become greater or lesser, or new effects may be seen. These may be unwanted or harmful. Alcohol may stop the benefits that some drugs – such as medicines, have on the body.
