Category: Adverse events

According to research, fatal adverse drug reactions (FADRs) account for approximately 3% of all deaths in the general population. This statistic underscores the importance of understanding **what are the most severe side effects** of medications and recognizing the signs of a serious adverse event.

According to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE), over a thousand different adverse events are graded on a severity scale from 1 to 5. The mildest of these is grade 1 toxicity, representing asymptomatic or mild symptoms that do not require significant medical intervention.
