What is Lybrel

LevonorgestrelThe Generic name of this drug
Treatment SummaryLevonorgestrel (LNG) is a hormone used for contraception and hormone therapy. It is also known as Plan B, and can be taken as a single dose for emergency contraception, inserted as an intrauterine device (IUD), or implanted as a long-term contraceptive. It was the first emergency contraceptive to contain only progesterone and was approved by the FDA in 1982. It has been demonstrated to be highly effective with few estrogenic side effects. Globally, levonorgestrel is the most commonly used emergency contraceptive.

Effectiveness

How Lybrel Affects PatientsLevonorgestrel is an emergency contraceptive that can help prevent pregnancy if taken within 72 hours of having unprotected sex. It works by stopping ovulation, fertilization, and implantation. This type of contraceptive is 89% effective when used according to the instructions. Intrauterine and implantable devices that release levonorgestrel are 99% effective in preventing pregnancy. Additionally, levonorgestrel used in hormone therapy can help reduce the risk of endometrial cancer caused by taking estrogen without other hormones.
How Lybrel works in the bodyLevonorgestrel works in several ways to prevent pregnancy. It suppresses the release of hormones that trigger ovulation, making it difficult for an egg to be released from the ovary. It thickens cervical mucus, making it more difficult for sperm to travel through the cervix and fertilize an egg. It can also alter the endometrium, making it harder for a fertilized egg to implant and develop. In hormone therapy, levonorgestrel helps prevent endometrial proliferation, which can lead to cancer when used with estrogen.

Lybrel for Abnormally Long or Heavy Periods
Lybrel has been an amazing addition to my life. I no longer have to deal with heavy periods or the side effects that come with them like anemia. In the 8 months since I've started taking this pill, I haven't had any bleeding or spotting and haven't experienced any negative side effects.

Lybrel for Endometriosis
Lybrel has been a game changer for me. I haven't had a period in years, and I used to suffer from debilitating menstrual pain, bloating, and other issues. This pill has helped me avoid all of that and has also not caused weight gain or acne like other birth control pills have.

Lybrel for Abnormally Long or Heavy Periods
Lybrel has been a life-changer for me. I used to get my period every April, but now I only have it for about three days. I've also lost the weight I gained from Depo and my mood swings are much more manageable. I would highly recommend this pill to anyone who is considering it.

Lybrel for Painful Periods
I've been on Lybrel for four years now and have had few problems. My period stopped the first month, and I haven't experienced any spotting since. It's wonderful not having to worry about my period or dealing with all the associated issues. The only significant downside is a decreased sex drive, but overall I'm very happy with this birth control pill and plan on taking it until menopause.

Lybrel for Endometriosis
I switched to Lybrel from Natazia five months ago in an attempt to stop my periods altogether, as per my doctor's orders. Unfortunately, I'm still menstruating regularly. Additionally, I've started having menstrual migraines again and the cramps are worse than ever. This pill doesn't seem to be working for me and I may have to switch brands again.

Lybrel for Birth Control
I was on the pill for three months with no issues, but this last month has been terrible. Bleeding for three weeks straight is not normal or manageable. I'm going to try a different method.

Patient Q&A Section about lybrel

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

Why is Lybrel discontinued?

"The decision to stop selling Lybrel was only because of money, not because it was unsafe. Many companies submitted licenses to the FDA to sell generic versions of the drug, so the company that makes Lybrel decided it wasn't worth selling anymore since they would make less money."

Answered by AI

Can you still get Lybrel?

"Lybrel is no longer available for purchase. Amethyst, manufactured by Watson Laboratories, is now the only option. Each pack of Amethyst contains 28 tablets (90 micrograms levonorgestrel/20 microgram Ethinyl estradiol).Jan 10, 2020"

Answered by AI

Does Lybrel stop your period?

"Lybrel can prevent menstruation in 59% of cases, and 20% of users only experience spotting, which does not require sanitary protection."

Answered by AI

Why was Lybrel discontinued?

"The decision to stop selling Lybrel was purely financial, driven by the number of generic brands of levonorgestrel-ethinyl estradiol submitted to the FDA. Lybrel was not taken off the market for safety reasons or recalled by the FDA."

Answered by AI

Is Lybrel available in the US?

"The Lybrel brand name has been discontinued, but there may be generic equivalents available."

Answered by AI

What is Lybrel used for?

"Lybrel is a medication that contains a combination of female hormones that are used as a form of contraception to prevent pregnancy. The brand name for this medication has been discontinued, but generic versions may still be available."

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.

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.
