About Drug Interactions

Drug interactions occur when a substance affects the activity of a drug when both are administered together. This interaction can be synergistic (when the effect is enhanced) or antagonistic (when the effect is diminished).

Interactions can alter how your medications work by changing the way they are:

  • Absorbed in your digestive system
  • Distributed through your bloodstream
  • Metabolized by your liver
  • Eliminated from your body
