Introduction

Budesonide and fluticasone are inhalable corticosteroids commonly prescribed for managing chronic respiratory conditions such as asthma and chronic obstructive pulmonary disease (COPD). This article provides detailed information about their uses, side effects, interactions, and other critical considerations to help patients and caregivers make informed decisions in conjunction with healthcare providers.
