Drug-Drug Interaction

With seniors, care providers often discover confusion over when and how to take medications. Drug-drug interactions may present added physical concerns to an older adult’s overall well-being.

A drug-drug interaction occurs when the effect of one drug is altered by the presence of another drug in the body.  Examples include:

  • One medication may reduce or increase the effects of another medication.
  • Two similar medications taken together may produce an effect that is greater than would be expected from taking one medication.
  • Two medications taken together may produce a new and dangerous interaction.

Drug interactions can also occur with over-the-counter medications – either with other over-the-counter medications or with prescription medications. That is why it is imperative that you check with the doctor or pharmacist to assure that over-the-counter medications and prescription medications do not have the potential to interact. A little extra caution can go a long way towards preventing unnecessary drug interactions.
