To describe common bleeding patterns and treatment strategies to minimize bothersome bleeding in users of progestin-based long-acting reversible contraception (LARC).
Most levonorgestrel intrauterine device users will establish a favorable bleeding pattern within a year; NSAIDs are the most effective bridge to help with bothersome bleeding during that time period. Early follicular phase insertion and fundal placement are associated with more favorable early bleeding profiles. Recent studies exploring tranexamic acid, mifepristone, and tamoxifen's adjunct role show modest or no benefit. The progestin implant is associated with more persistent unpredictable bleeding disproportionately affecting women with higher etonogestrel serum levels; recent studies indicate that oral contraceptives, ulipristal acetate, and tamoxifen may all provide temporary relief.
Women's healthcare providers can offer patients adjunct medical therapies to minimize bothersome bleeding associated with progestin LARC use, which may result in increased satisfaction and continuation rates of these effective forms of contraception.
描述孕激素类长效可逆避孕(LARC)使用者常见的出血模式和治疗策略,以尽量减少因出血带来的不适。
大多数左炔诺孕酮宫内节育器使用者在一年内会建立一个良好的出血模式;在这段时间内,非甾体抗炎药是最有效的缓解出血不适的方法。在早期卵泡期放置和宫底放置与更有利的早期出血模式相关。最近的研究探索了氨甲环酸、米非司酮和他莫昔芬的辅助作用,结果显示其效果不大或没有效果。孕激素埋植剂与更持久、不可预测的出血有关,这种出血不成比例地影响血清依诺孕酯水平较高的女性;最近的研究表明,口服避孕药、醋酸乌利司他和他莫昔芬都可能暂时缓解这种情况。
女性健康护理提供者可以为患者提供辅助医疗治疗,以尽量减少因使用孕激素 LARC 引起的出血不适,这可能会提高这些有效避孕方法的满意度和续用率。
