What is Norplant

Levonorgestrel

The Generic name of this drug

Treatment Summary

Levonorgestrel (LNG) is a synthetic progestogen hormone used for contraception and hormone therapy. It is often sold under the brand name Plan B and is used as an emergency contraceptive pill or in an intrauterine device (IUD) such as Jaydess, Kyleena, or Mirena. It can also be used in a subdermal implant to provide long-term contraception. Levonorgestrel was first approved by the FDA in 1982 and is one of the most widely used emergency contraceptives due to its high levels of efficacy and lack of estrogenic side effects compared to other emergency contraceptive regimens

Effectiveness

How Norplant Affects Patients

Levonorgestrel is used as an emergency contraceptive to prevent pregnancy. It works by preventing ovulation, fertilization, and implantation. If used within 72 hours after intercourse, the levonorgestrel-only pill is 89% effective. Higher levels of effectiveness (over 99%) are achieved when using intrauterine or implantable devices that release levonorgestrel. Additionally, levonorgestrel is used in combination with estrogen to help protect against endometrial cancer.

How Norplant works in the body

Levonorgestrel is an oral contraceptive and hormone therapy that works to prevent pregnancy. It stops ovulation by slowing the release of hormones from the hypothalamus. It also thickens cervical mucus so that sperm cannot reach the egg, and can cause changes to the endometrium, making it harder for a fertilized egg to implant. For hormone therapy, levonorgestrel works with estrogen to reduce the risk of endometrial cancer.

Norplant for Birth Control

I had the implant for five years and it was a very easy procedure to remove. I did experience irregular cycles and lots of spotting, but otherwise I had no ill side effects. The only downside is that it can cause irregular periods, but other than that I would recommend this to anyone looking for long-term birth control.

Norplant for Birth Control

I only gained about five pounds in weight, which was the only side effect I experienced. I had three separate Norplants over the course of five years. In my opinion, this is the best form of birth control and I'm disappointed it's not an option for my daughters.

Norplant for Birth Control

I had this product inserted when I was 20 and removed it about six months later. Unfortunately, I nearly went blind as a result and ended up in the emergency room on Christmas Eve in 1992. The doctor who removed it swore he would never remove another one; it took him almost three hours to get it out. Consequently, I have a large scar on my arm from where he had to dig it out. All things considered, I would not recommend this product to anyone.

I had the Norplant contraceptive implanted after the birth of my child at 15. I experienced a lot of symptoms and had it removed within a year. 16 years later, I'm still dealing with abdominal discomfort, headaches, visual disturbance, severe depression and anxiety, mood swings, and many other issues. I feel like Norplant is to blame for my current condition and I would not recommend it to anyone.

I had the norplant put in after my son was born. I wanted to wait a few years before having more kids. I had it put in in 1999 and had it removed in 2004. After that I tried getting pregnant and was unable to. The dr. said it had nothing to do with the norplant, but after 5 years of trying I finally gave up on getting pregnant.

Sculptra + Restylane for Post-Menopausal Skin Concerns

40 - 65
Female
Montreal, Canada

The post-menopausal state is marked by a sharp decline in estrogen, leading to significant structural and functional changes in the skin, including collagen loss, dryness, thinning, and reduced elasticity. To address these concerns, aesthetic injectables products such as Sculptra® Aesthetic (poly-L-lactic-acid \[PLLA- SCA\]) and Restylane Skinboosters®\[HASBV\] (small-particle hyaluronic acid - SP-HA) can be used. PLLA-SCA stimulates collagen production via cellular activation (biostimulator), gradually improving dermal structure. HASBV enhances hydration, elasticity, and skin texture when injected under the skin. Considering that hydration and laxity represent the primary aesthetic concerns in this patient population. Targeted treatment with SP-HA (HASBV) to improve hydration and PLLA-SCA to address laxity have been shown to produce significant clinical outcomes by directly addressing these key dermal deficiencies. This approach forms the basis of the current study.

Ketamine for Pelvic Pain

18 - 89
Female
Cleveland, OH

The purpose of this research study is to see if ketamine infusion during surgery can decrease pain after surgery. Ketamine is a medication commonly used as part of anesthesia during surgery and is approved by the US FDA. Patients will be randomized to either receive standard anesthesia with OR without ketamine. The surgical procedure will be the same regardless of which group patients are randomized to. After surgery, patients will be asked to rate their pain in the post-operative observation unit and at their two-week post-operative visit. No additional visits are required for participation in this study. The investigators estimate the surveys will take approximately 10 minutes to complete.

Moderate Aerobic Exercise for Menstrual Symptoms

18 - 40
Female
Colorado Springs, CO

The goal of this clinical trial is to evaluate the impact of moderate aerobic exercise on menstrual symptom management in sedentary women both using and not using hormonal contraceptives. The main questions it aims to answer are: Is there a reduction in physical and/or psychological menstrual cycle related symptom burden with participation in moderate aerobic exercise for sedentary women using and not using hormonal contraceptives? Is there a difference in physical and/or psychological menstrual cycle related symptom burden between hormonal contraceptive and non-hormonal contraceptive users? Is a moderate aerobic exercise intervention more effective in reducing physical and/or psychological menstrual related symptom burden for sedentary women using or not using hormonal contraceptives? Participants will: * Have their body composition assessed using dual energy X-ray absorptiometry pre and post exercise intervention. * Complete a Menstrual Symptom Index (MSi) to report daily menstrual cycle related symptom burden in addition to the Premenstrual Symptom Screening Tool (PSST) and Heavy Menstrual Bleeding (HMB) questionnaire monthly. * Utilize an at-home monitor to test urinary luteinizing hormone, estrone-3-glucuronide, and pregnanediol glucuronide approximately 10 times per month and report menstrual cycle length. * Record physical activity habits by continuously wearing a wrist-based accelerometer and chest-strap heart rate monitor during planned aerobic exercise sessions and complete the International Physical Activity Questionnaire (IPAQ) monthly. * Maintain their usual sedentary activity habits for one menstrual cycle followed by completion of an exercise intervention designed to progress individuals to meet minimum recommended aerobic physical activity guidelines of 150 minutes per week set by the American College of Sports Medicine for two menstrual cycles.

Mirena for Endometrial Hyperplasia

18+
Female
Birmingham, AL

Researchers are looking for a better way to treat women with nonatypical endometrial hyperplasia (NAEH). Endometrial hyperplasia is a condition where the lining of the uterus (called the endometrium) becomes too thick. Nonatypical means that the condition is not cancerous. It is often caused by hormone imbalances in women. Symptoms can include abnormal vaginal bleeding or irregular periods. If this condition is not treated, then it may lead to cancer. Currently, there are no approved treatments for NAEH and that is why there is still an unmet medical need. The study treatment, Mirena (also known as BAY 865028), is already available as a type of birth control device. It is inserted into the uterus where it gradually releases progesterone. In this study, researchers want to find out if Mirena works for women with NAEH. They believe it can help by keeping hormone levels balanced in the body. The main purpose of this study is to show that uterine lining goes back to completely normal lining after treatment with Mirena and that its use is safe in this population. For this, the researchers will compare the number of participants with benign endometrium after 6 months of treatment with Mirena or oral MPA. The study participants will be randomly assigned into one of two treatment groups. The randomization will be done 2:1 ratio, meaning that for every two participants assigned to Mirena, one will be assigned to oral medroxyprogesterone acetate (MPA). Based on their group, participants will receive Mirena, which is inserted into the uterus at the start of the study, or they will take progestins once daily by mouth for 6 months. Each participant will be in the study for around 10 months with up to 5 visits to the study clinic/site. Participants will visit the study clinic: * once before the treatment starts * 3 times with a gap of 3 months between the visits during the treatment * then 1 more time after the treatment ends During the study, the doctors and their study team will: * check participant's health by performing tests such as blood and urine tests * perform vaginal ultrasound and hysteroscopy. Hysteroscopy is a minor surgical procedure where a thin camera will be inserted into the womb to check for any abnormality. Sampling of the endometrial lining (cells in the womb) will be done with a thin tube at the same time. * take samples of womb (endometrial) lining * ask the participants questions about how they are feeling and what adverse events they are having An adverse event is any medical problem that a participant has during a study. Doctors keep track of all adverse events, irrespective if they think it is related or not to the study treatment.

Female
Hosuton, TX

This exploratory, proof-of-concept study is a double-blind (participants and investigators will be blinded), placebo-controlled, randomized, two-arm clinical trial of Marinol \[dronabinol, synthetic Δ9-tetrahydrocannabinol (THC)\] for e endometriosis-associated chronic pelvic pain (endo-CPP) with a 2:1 allocation ratio. Up to 75 subjects will be enrolled in this pilot study and randomized to receive doses of THC (up to 30 mg/day), orally, over 8 weeks. This study will be conducted at a single site; it does not include any stratifications, and there is no interim analysis planned. Notably, the goal is to determine whether there is enough evidence of the safety of THC to support the development of later-phase clinical trials. Thus, detailed developmental plans are contingent on the outcomes of this study.
