An OTC vaginal cream contains estriol for vaginal atrophy. What is the maintenance dose?

• A. One application daily
• B. One application twice daily
• C. One application three times weekly
• D. One application twice weekly

Answer: (D)

Focusing on maintaining vaginal mucosal health with the lowest effective exposure is the main idea here. After a short initial phase that rapidly restores the vaginal lining, the goal is to keep those benefits with a dosing schedule that minimizes estrogen exposure while still preventing relapse of symptoms. For estriol vaginal cream used for vaginal atrophy, the maintenance approach that fits this balance is to apply the cream twice weekly. This frequency provides ongoing local estrogen effect to preserve tissue thickness and lubrication without the higher exposure that daily or twice-daily use would entail. Using daily or more frequent dosing would add unnecessary estrogen exposure once the mucosa is stabilized, while a schedule like three times weekly is not as consistently sufficient for maintenance in typical practice. Thus, twice weekly is the practical, effective maintenance pattern.
