Idiopathic pulmonary fibrosis (IPF) is a group of diseases in which the main loci of lesions, mainly inflammatory and fibrotic, are within the interstitium of the alveolar and bronchiolar regions. Steroid therapy is the standard treatment for acute exacerbation of IPF, whereas antifibrotic agents are the standard treatment for chronic IPF. However, the vulnerability of older patients indicates that these treatments may be discontinued. Here, we report the case of an 86-year-old woman who had a dry cough for over a year and was subsequently diagnosed with IPF based on imaging studies. After using steroid pulses to treat acute exacerbations, the patient was transitioned to the chronic management phase, and time was allowed to plan the patient's advanced care with her family. The use of high-dose steroids in older patients with frailty is contraindicated. This case emphasizes the importance of considering initial intensive treatment for IPF in older patients for better palliative care.
