Heavy Menstrual Bleeding | Pretreatment With Norethindrone Acetate Prior to Levonorgestrel IUS Insertion for Heavy Menstrual Bleeding

Heavy Menstrual Bleeding research study

What is the primary objective of this study?

Problematic uterine bleeding after the insertion of the LNG IUS is a well documented side effect. The levonorgestrel intrauterine system (LNG IUS) was approved for treatment of heavy menstrual bleeding (HMB) by the FDA in October 2009. To reduce the incidence and severity of post-insertional uterine bleeding, pretreatment with norethindrone acetate may effectively slough the endometrium prior to insertion of the LNG IUS.

Study Interventions

Interventions can include giving participants drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available or noninvasive approaches such as surveys, education, and interviews.

Drug:Norethindrone acetate pretreatment5 mg tablets, three times a day for 21 days for 2 menstrual cycles.

Other:No pretreatmentLVN IUS is placed withour Norethindrone acetate pretreatment.

Study Arms

Research studies and clinical trials typically have two or more research arms. An arm is a group of people who receive the same treatment in the study.

Norethindrone acetate pretreatmentThis arm will receive two cycles of norethindrone acetate before LVN IUS insertion.

No pretreatmentLVN IUS is placed without norethindrone acetate pretreatment.
