Prevalence and factors associated with polypharmacy among patients with rheumatoid arthritis: a single-centre, cross-sectional study.

Considering that polypharmacy and excessive polypharmacy are associated with a history of hospitalisation and glucocorticoid medication in patients with rheumatoid arthritis, medications during hospitalisation should be monitored, and glucocorticoids should be discontinued. Key points • The proportion of polypharmacy (five or more medications administered orally regularly) was 61%. • The proportion of excessive polypharmacy (10 or more medications administered orally regularly) was 15%. • Medications during hospitalisation should be reviewed and examined, and glucocorticoids should be discontinued.
