Resumo
Strong CYP3A4 inhibitors increase erdafitinib exposure, raising the risk of adverse effects such as hyperphosphatemia, stomatitis and ocular toxicity.
O que esta interação significa em palavras simples
Clarithromycin and Erdafitinib can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Clarithromycin belongs to Anti Bacterial; Erdafitinib belongs to Oncology.
Por que acontece
Clarithromycin inhibits CYP3A4, which contributes to erdafitinib metabolism along with CYP2C9.
O que fazer
Use a non-CYP3A4-inhibiting antibiotic where possible. If unavoidable, monitor closely for erdafitinib toxicity and reduce the dose as needed, then reassess after clarithromycin is stopped.
