Filter by:This is a randomised controlled trial aimed at comparing the efficacy of levonorgestrel (LNG) co-administered with piroxicam or placebo for oral emergency contraception (EC). Piroxicam is a non-steroidal anti-inflammatory drug (NSAID) commonly used as a pain-killer in inflammatory conditions. Efficacy will be measured as the percentage of pregnancies prevented.
Background: The prevalence of repeat unprotected intercourse after EC use in the same cycle demonstrate the need for more self-bridging emergency contraceptive options. We propose the use of intramuscular Depot Medroxyprogesterone acetate (DMPA) as EC, which has been shown to inhibit follicular activity within 24 hours, and provide on-going contraception via suppression or disruption of ovulation. Objective: The objective of this study is to explore the potential of depot medroxyprogesterone acetate (DMPA) given as a 150-mg intramuscular injection for use as an emergency contraceptive. Study population: Healthy regularly menstruating women aged 18-39 years old will be invited to participate if they fulfill inclusion criteria. The participants will undergo a screening visit during the midluteal phase of their cycle, and will be enrolled if a serum progesterone level is >3ng/ml. Methodology: Participants will be assigned to one of three groups based on leading follicle size. Starting cycle Day 8, transvaginal ultrasounds will be performed to assess the size of the leading follicle. Once the follicle has reached the pre-assigned size, 150 mg IM DMPA will be administered. Blood will be collected for baseline hormonal assays. For 5 consecutive days, daily blood will be drawn for hormonal assays and daily transvaginal ultrasound will be performed to assess for signs of ovulation. The participant will then return for twice weekly progesterone levels for 2 weeks for study completion.
This study is designed to assess whether consumers select and use ella® (ulipristal acetate 30mg), an emergency contraceptive, in a manner consistent with the OTC package directions in an OTC-like setting.
Women using an emergency contraceptive method must use back up protection for 1-2 weeks depending on method. The Copper-IUD is the most effective emergency contraceptive method. The investigators wish to explore if women choosing the Cooper IUD have a higher frequency of use of an effective contraceptive method 3 months and 6 months after the use of an emergency contraceptive method than women who choose to use the emergency contraceptive pill EllaOne (ulipristal acetate).
The purpose of this study is to see how often women who come to a family planning clinic for emergency contraception, the morning after pill, are willing to use either the copper IUD or the levonorgestrel IUD. The investigators will also see if pregnancies occur in those choosing the levonorgestrel IUD and if people continue to use the IUD for 1 year.
The study is aimed at assessing the clinical follow-up and the outcomes of pregnancies exposed to ella, whether due to failure of the emergency contraception or inadvertent exposure during pregnancy.
The purposes of this study are to compare the effects on ovarian activity of quick starting a Combined Oral Contraceptive Pill (COCP) after ellaOne® or placebo intake.
This is a non-comparative case series study to assess the ability of females 11-16 years of age, inclusive, who are requesting emergency contraception (EC) to use the study product, DR-104 (Plan B® 1.5), appropriately and safely without provider counseling.
The purpose of this study is to compare the efficacy, safety and acceptability of pre-treatment with mifepristone and misoprostol compared to misoprostol alone in the medical termination of pregnancy by mifepristone EC failure.
The purpose of this study is to assess the safety and efficacy of CDB-2914 for preventing pregnancy when taken 3 to 5 days after unprotected sexual intercourse.
