Oral Antibiotics and Risk of Serious Cutaneous Adverse Drug Reactions

Serious cutaneous adverse drug reactions (cADRs), or severe drug rash, are a group of rare but potentially life-threatening delayed reactions involving the skin and, often, internal organs. Some of these reactions carry mortality rates from 20 to 40%. While many different classes of drugs can cause serious cADRs, antibiotics are among the most commonly reported triggers for these reactions. ![twitter](https://images.medindia.net/icons/news/social/twitter.png)

Antibiotics: Hidden Risks and Safer Options
“Clinicians have speculated that certain antibiotics carry greater risk for these severe reactions, but no study has ever confirmed these claims” says Erika Lee, an allergist and a trainee with ICES and Temerty Medicine’s Eliot Phillipson Clinician-Scientist Training Program. “Our objective was to explore the risk for cARDs in a population of older adults, who tend to receive disproportionately more antibiotic prescriptions than younger adults.”Published in the journal JAMA, this case-control study used healthcare data from ICES of adults 66 years or older who received a prescription for at least one oral antibiotic between 2002 and 2022 in Ontario, Canada.
Over the study period, 21,758 adults had an ED visit or hospitalization for a serious cADR following oral antibiotics and were matched with 87,025 controls who did not have a reaction.
“The good news is that most patients who visited the hospital with these reactions were discharged without being admitted, so that should be reassuring to providers and patients,” says Lee. “However, of those who were admitted to hospital with the most severe reactions, twenty percent were treated in the ICU, and five percent of hospitalized patients died, which underscores the need for careful prescribing practices.”

Key findings include:
- There were 2 cADR-related hospital visits for every 1000 antibiotic prescriptions dispensed.
- About 1 in 8 patients presenting to the ED with antibiotic-related cADRs was hospitalized, likely because their reactions were more severe or because of concerns about potential complications.
- 20% of hospitalized patients with the most severe forms of cADRs were treated in a critical care unit, and 5% of those patients died.

“It’s also one more reason why antibiotics should be prescribed only when they’re truly needed,” he adds.
