Résumé

Clarithromycin strongly inhibits CYP3A4 and can markedly raise budesonide exposure, increasing the risk of systemic corticosteroid effects such as adrenal suppression and Cushingoid features. The risk is greatest with prolonged use.

Ce que signifie cette interaction, en termes simples

Budesonide and Clarithromycin 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.

Budesonide belongs to Respiratory; Clarithromycin belongs to Anti Bacterial.

Niveau de preuve: High

Pourquoi elle survient

Strong CYP3A4 inhibition reduces budesonide first-pass and systemic clearance.

Conduite à tenir

Avoid the combination with oral budesonide where possible, or use a short antibiotic course with monitoring for hypercortisolism. Consider an alternative macrolide such as azithromycin.
