Xerostomia as a Rare Adverse Effect of Low-Dose Oral Minoxidil: A Case Report with Recurrence After Re-Challenge

This case report discusses xerostomia, or dry mouth, as a rare adverse effect of low-dose oral minoxidil (LDOM), which is increasingly used off-label for treating androgenetic alopecia. The report highlights a specific case where xerostomia recurred upon re-challenge with LDOM, suggesting a potential link between the medication and this side effect. While LDOM is favored for its efficacy and convenience over topical treatments, this case underscores the importance of monitoring for less common side effects in patients undergoing treatment.
