What is an adverse drug event?
An adverse drug event (ADE) is the harmful or unintended effect of or reaction to a medication
given in the accepted doses. Adverse drug events may include difficulty breathing, skin rash,
itching, swelling, racing heartbeat, nausea and/or vomiting, diarrhea, feeling faint, or severe
depression. Adverse drug events of this type are usually referred to as side effects.
While many ADEs are mild, some adverse drug events can be life threatening, requiring hospitalization, or they may even be fatal.
Communicating with your doctor is essential if you experience any unwanted side effects from medication. Be sure to ask your pharmacist any questions you may have about side effects of the medication you are taking.
