BACKGROUND: Finasteride is commonly prescribed for androgenic alopecia and benign prostatic hyperplasia. However, concerns regarding its safety have been growing as cases of cognitive dysfunction have been reported.
METHODS: A disproportionality analysis was conducted on data collected between 1967 and 2022 to explore the potential association. Cases of cognitive dysfunction associated with finasteride use were identified, and the reporting odds ratio (rOR) was calculated with 95% confidence intervals to determine the strength of the association between the two variables. Sensitivity analyses were conducted to account for confounding by indication.
RESULTS: Among the 54,766 cases of adverse events reported for finasteride use, 1,624 (2.97%) were associated with cognitive dysfunction. The study found a significant disproportionality for cognitive dysfunction related to finasteride use (rOR 5.43, 95% CI 5.17-5.71). Most cases were considered serious (65.83%), with no signs of recovery (58.37%). Sensitivity analyses showed that patients younger than 45 years (rOR 7.30, 95% CI 6.39-8.35) and those with alopecia (rOR 5.52, 95% CI 5.15-5.91) reported more cognitive dysfunctions than their counterparts.
CONCLUSION: This study showed an increased reporting of cognitive dysfunction associated with finasteride use, especially among younger alopecia patients. Finasteride should be prescribed with caution, especially to younger alopecia patients.
