Abstract

The present invention teaches that daily, cyclical vaginal delivery of progestin may be used to provide regular, predictable withdrawal bleeding during hormone replacement therapy. The present invention also teaches that constant administration of progestin in a water-insoluble, water-swellable cross-linked polycarboxylic acid polymer may be used to maintain amenorrhea. Either regimen is accompanied by a significant decrease in adverse side effects.
