First, it’s true: some people use methadone to get high. It’s a synthetic opioid with
mild sedative and euphoric properties similar to other opioids

antagonistic
(combining the drugs leads to a smaller effect than expected).
Who is at risk for drug-drug interactions?
Anyone who is taking more than one drug
is at risk. Some populations are at higher risk, such as older adults who typically take more than one medication for chronic conditions, and people who take multiple drugs as part of standard treatment regimens for certain diseases.
There are several risks when taking multiple medicines
. You may be more likely to have side effects. Because most medicines can have side effects, the more medicines you take, the more likely you will have side effects. Taking certain medicines can also increase the risk for falls.
Synergism: when the combine effect of two drugs is greater than the sum of their effects when given separately.
