drug interaction
Combined medication effects
A drug interaction occurs when one drug affects the action of another—amplifying, diminishing, or altering its effects.
Interactions can also happen between drugs and foods, supplements, or medical conditions.
Some interactions are dangerous: Mixing alcohol with sedatives can be fatal.
Others are intentional: doctors may combine drugs whose interactions enhance treatment.
