LevonorgestrelThe Generic name of this drug
Treatment SummaryLevonorgestrel (LNG) is a synthetic hormone used as a form of contraception and hormone therapy. It is sold under the brand name Plan B and can be taken as a single dose emergency contraceptive pill, released from an intrauterine device (IUD), or as a long-term subdermal implant. Levonorgestrel is the most widely used emergency contraceptive and was approved by the FDA in 1982. It is considered highly effective and does not have the estrogenic side effects of older emergency contraceptive regimens.

Effectiveness

How Plan B One-Step Affects PatientsLevonorgestrel is a hormone used as an emergency contraceptive and in certain contraceptives to prevent pregnancy. It works by interfering with ovulation, fertilization, and implantation. If taken as directed within 72 hours of intercourse, it has an 89% success rate. Implantable or intrauterine devices containing levonorgestrel have an over 99% success rate. Additionally, levonorgestrel is sometimes used in hormone therapy to help prevent endometrial cancer caused by estrogen.
How Plan B One-Step works in the bodyLevonorgestrel is a hormone used in oral contraceptives that stops ovulation by slowing the release of gonadotropin-releasing hormone from the hypothalamus. This hormone usually signals for the release of luteinizing hormone, which causes ovulation. Levonorgestrel also thickens cervical mucus, making it hard for sperm to move and survive, and changes the endometrium making it less likely for a fertilized egg to implant. When used with estrogen in hormone therapy, levonorgestrel helps reduce the risk of endometrial cancer.

Plan B One-Step Reviews: What are patients saying about Plan B One-Step?

5Patient Review

Plan B One-Step for Postcoital Contraception
I took Plan B once and had no side effects. My period was on time after I took this drug. The only negative side effect was the fact that a month after I took plan b my period was ten days so it may mess with your cycle, but then everything will be normal again.
5Patient Review
3/1/2014
Plan B One-Step for Postcoital Contraception
I had sex without a condom and took Plan B about an hour later. I was in the middle of my fertile period, so there was a pretty high chance that I could have gotten pregnant. But after taking the pill, I experienced no symptoms whatsoever! I was really worried that it hadn't worked, but sure enough, my period came exactly two weeks later. So this pill is definitely effective!

Plan B One-Step for Postcoital Contraception
Though it was effective, my period came a week early after taking this pill. The next month it came three weeks late. I took a pregnancy test to be sure, and it turned out negative; however, I would still recommend caution if you're considering this medication.

Plan B One-Step for Postcoital Contraception
I took this medication approximately eighteen hours after unprotected sex. I didn't experience any immediate side effects, but a few days later I had some issues with anxiety and mood swings. It was like being a hormonal thirteen-year-old again. Additionally, I felt fatigue and dizziness. Despite the negative experiences, it did work; I didn't get pregnant. So, all in all, it was worth the fifty dollars and the side effects!

Plan B One-Step for Postcoital Contraception
At first, I had no issues with this medication. However, my period came a few days early (which isn't necessarily a bad thing). But when it did come, the pain was intense. It felt like childbirth all over again. The blood was also bright red. Thankfully, a hot bath provided some relief; however, the pain lasted throughout my entire period (although it did lessen eventually).

Plan B One-Step for Postcoital Contraception
I was pleased with how well this worked in terms of preventing pregnancy; however, it threw my hormones out of whack and caused me to gain weight rapidly. Additionally, I developed acne as a result of taking this medication.

Plan B One-Step for Postcoital Contraception
I took Plan B as directed after having unprotected sex. Unfortunately, I was one of the small percentage of women for whom it did not work and I ended up pregnant.

6/20/2016
Plan B One-Step for Postcoital Contraception
I got pregnant even though I took the pill within two hours of the condom breaking. Unfortunately, I miscarried later on. The doctor said it might have been because I had morning sickness and a stomach flu at the same time and couldn't eat for almost two weeks.

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.

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.

NettleEndo for Endometriosis

22 - 45
Female
San Francisco, CA
The goal of this clinical trial is to learn if a wearable brain stimulation device called NettleEndo can reduce chronic pelvic pain and improve wellbeing in women with endometriosis. The study also aims to assess the safety and usability of the device when used at home over several months. The main questions it aims to answer are: 1. Does at-home transcranial direct current stimulation (tDCS) reduce daily pain intensity in women with endometriosis? 2. Does the device also improve mood and sleep quality? Researchers will compare two groups-one receiving active brain stimulation and one receiving a sham (placebo) stimulation-to see if the active device provides greater improvements in symptoms. Participants will: 1. Use the NettleEndo device at home for 20 minutes per session, five times per week for 12 weeks 2. Be randomly assigned to receive either real or sham stimulation through the device 3. Complete daily and weekly symptom ratings through a mobile app 4. Wear an optional fitness tracker to collect data on sleep, movement, and heart rate variability 5. Be followed for 60 days after completing the intervention to monitor longer-term effects All activities are completed remotely using a smartphone app. Participants can contact the study team with questions at any time. The study is double-blind, meaning neither participants nor the researchers assessing outcomes will know who received active or sham treatment until the end of the trial.

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.

Dronabinol for Endometriosis

18 - 64
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.
