Adverse Drug Reactions: An Overview

10m of CPD
About 250,000 Australians are hospitalised every year for medicine-related reasons, including adverse drug reactions. Over half of these hospitalisations are thought to be preventable. Ensuring the safe use of medicines is a crucial component of patient safety. Therefore, any known or new adverse drug reactions should always be documented, monitored and communicated appropriately to prevent re-exposure.

What is this article about?

Adverse drug reactions (ADRs) are unwanted or harmful reactions to medicines that were taken under normal conditions of use. These reactions are related to the medicines themselves rather than other factors. Any medicine has the potential to cause an adverse drug reaction, even those derived from natural sources. ADRs can range from minor, uncomfortable side effects to dangerous and potentially life-threatening reactions.

Sometimes I find it really hard to make time for my learning, but I was blown away by how easy it is with the Ausmed app. I can fit it in during breaks or on the bus to work.
