Effectiveness

How Previfem Affects Patients

Ethinylestradiol is a synthetic form of estrogen that helps stop ovulation and can reduce the growth of the lining of the uterus. This drug usually only needs to be taken once daily, and it is considered to be very safe even with an overdose. However, patients should be aware of the potential risks of developing blood clots while taking this drug.

How Previfem works in the body

Ethinylestradiol is a synthetic version of the female hormone estrogen. Taking ethinylestradiol can reduce bone density and stop ovulation. It does this by reducing the levels of hormones needed for ovulation, thickening the cervical mucus to block sperm, and stopping changes in the endometrium that are necessary for pregnancy. It also lowers luteinizing hormone and increases sex hormone binding globulin.

When to interrupt dosage

The suggested dosage of Previfem is contingent upon the diagnosed disorder, such as Acne Vulgaris, Hormonal Contraception and Folate supplementation therapy. The quantity of dosage is contingent upon the technique of delivery as detailed in the table below.

Previfem for Birth Control

I've been taking Previfem for about 7 months and have had great results. I didn't experience any side effects after the initial adjustment period, and I've actually found that my periods are lighter and shorter now. Highly recommend!

Previfem for Birth Control

I've been using Previfem for three months now. The good: my periods have gone from seven days to five. The bad: I felt slightly nauseous after taking the pill during the first two months, but that has since subsided. All in all, it's a great birth control pill!

Previfem for Endometriosis

I've been using this pill for two years now and it has really changed my life. I used to throw up and have unbearable pain during my periods, which would last up to two weeks. This pill has helped with all of that and my skin is now flawless. I haven't had any negative side effects, either.

Previfem for Painful Periods

I gave this pill a fair chance, but had to stop taking it after six weeks due to the severe mood side effects. I was constantly irritable, depressed, and experienced extreme swings in my mood. Additionally, my libido disappeared entirely. The first few weeks I also felt nauseous every day, but that eventually went away. Though the pill itself was effective, the side effects were not worth it and so I switched pills.

Previfem for Birth Control

I've been on this medication for four months now, and I'm starting to feel really uncomfortable. I'm nauseous more often than not, and I feel bloated all the time. Even if I stick to a strict diet, I can't seem to lose any weight. I think I'm going to switch medications next month.

Previfem for Endometriosis

I was taking this medication for my endometriosis, but by the eighth day I became very dizzy all the time. I continued to take them for 15 days total before I could no longer function due to being dizzy no matter what I did. So I called and had my Dr change my birth control; so far it's been three days and the dizziness seems to be subsiding.

Lidocaine for Pain Control in Birth Control

Female
La Jolla, CA

The goal of this research study is to learn more about how different uses of a numbing medication might affect pain levels while getting an IUD placed. The investigators are also studying participants opinions of their clinicians' empathy. The investigators are inviting patients who arrive at their clinic visit seeking an IUD. Usually, at University of California, San Diego (UCSD), for patients who have never delivered a baby, clinicians use a buffered paracervical block for before IUD placement. The purpose of this research study is to investigate whether a "buffered" (2 cc of sodium bicarbonate, 18 cc of 1% lidocaine) paracervical block (numbing medication given on both sides of the cervix) is effective in reducing pain during IUD placement in individuals with prior C-sections, the difference between buffered and unbuffered for nulliparous patients, and whether a medicated gel reduces pain with the paracervical block.

The goal of this clinical trial is to learn if use of the HAPPI software can improve pharmacist-provided birth control services. The main questions it aims to answer are: 1. Does the HAPPI software make it easier for pharmacists to provide birth control services in their pharmacy? 2. Does the HAPPI software make it easier for patients to access birth control? Researchers will compare pharmacists' implementation and patients' access when using the HAPPI software and when not using the HAPPI software to see if the software improves implementation and access. Participants will include pharmacists and patients. Pharmacists will be asked to provide birth control services as normal while using the HAPPI software. Patients will be asked to receive birth control services from a pharmacist as normal, while using the HAPPI software.

Electronic Health Record Platform for Birth Control

Calabasas, CA

Hormonal contraceptives are medications that require a prescription, traditionally from a physician or advanced practice provider. Over the past decade, pharmacists have gained the authority to prescribe contraceptives in many states, allowing patients to access these medications directly in pharmacies without first seeing another healthcare provider. The Pharmacist Resource to Implement Services as Modules (PRISM) is an Electronic Health Record platform designed to streamline workflows and provide clinical decision support, making it easier and safer to deliver clinical services in community pharmacies. This pilot study will evaluate patient-reported outcomes for women receiving contraceptive services from pharmacists using the PRISM platform at five community pharmacies across the United States over a 12-week period. The study will assess the quality of care, contraception continuation and failure rates, side effect rates, preventative healthcare utilization, and overall patient experience with pharmacy contraceptive services.

PEN-3 Intervention for Postpartum Depression

18 - 45
Female
Jackson, MS

Maternal mortality in the United States is higher than in peer nations and has not decreased since 1990. Beyond mortality, severe maternal mortality impacts far too many women. Not only are these high rates alarming, but notable racial/ethnic and socioeconomic disparities exist. These inequities are highly regional, with women living in the rural southeast part of the United States, including the Mississippi Delta, having the highest rates of maternal mortality and morbidity. Unfortunately, these disparities have proven to be stubbornly resistant to interventions, necessitating an innovative multifaceted approach focused on community practice, building trust, and prioritizing patient voices. To meet this need, this proposal aims to establish the Mississippi Delta Research Center of Excellence for Maternal Health with the goal of addressing preventable maternal mortality, decreasing severe maternal morbidity, and promoting maternal health equity in partnership with the Mississippi Delta community. This patient-clinical linkages intervention study will evaluate the effectiveness of a multilevel and multisector communication and health literacy strategy to increase trust and engagement in postpartum healthcare among women in the Mississippi Delta, with a specific focus on Black women, their families, and their communities. These research projects both have the overarching goal of partnering with the community to determine and meet the needs of pregnant and postpartum women in the Mississippi Delta and address the disparities within maternity health and health care outcomes.

Birth Control Pills and DNA Interaction

18 - 45
Female
Aurora, CO

The goal of this clinical trial is to evaluate how differences in specific parts of our DNA can influence how individual bodies break down the hormones contained within oral contraceptive pills, which could affect how well these birth control pills work to prevent pregnancy. The investigators are also interested in exploring how these differences in our DNA can also explain why patients taking the exact same formulation of birth control pill will experience very different side effects. The main questions it aims to answer are: * Do individuals with the CYP3A7\*1C variant have increased metabolism of both desogestrel and ethinyl estradiol when taking a combined oral contraceptive pill? * Do individuals with the CYP3A7\*1C variant experience higher rates of breakthrough ovulation while taking a desogestrel/ethinyl estradiol combined oral contraceptive pill? * What novel genetic loci are associated with alterations in steroid hormone pharmacokinetics and pharmacodynamics among a larger cohort of combined oral contraceptive pill users? Participants will take a specific formulation of combined oral contraceptive pill (desogestrel/ethinyl estradiol) and undergo the following procedures: * Blood draw to measure the amount of progestin and estrogen in their system from the combined oral contraceptive pill * Questionnaires to assess side effects possibly caused by the combined oral contraceptive pill * Blood draw to measure endogenous hormone levels and biomarkers that may be affected by the combined oral contraceptive pill * A transvaginal ultrasound to measure any ovarian follicles (optional procedure)

Boston, MA

The goal of this clinical trial is to test the effectiveness of evidence-based Screening, Brief Intervention, and Referral to Treatment (SBIRT) among adult patients who screen positive to one or more risky alcohol or substance use behaviors while seeking care at a sexual and reproductive health (SRH) clinic. The main questions it aims to answer are: * Does SBIRT impact patients' alcohol and substance use, SRH, mental health, physical health, quality of life, and wellbeing? * Does SBIRT effectiveness differ by ethnicity, socioeconomic status, age, gender, and urbanicity? * Does SBIRT effectiveness differ by delivery mode (in-person vs. telemedicine)? Participants will receive in-person and telemedicine SBIRT, or usual care. Participants will complete surveys at interviews at baseline, 30 days, and 3 months. Researchers will compare patients who received SBIRT to patients who receive usual care to see if patients who receive the SBIRT intervention have a greater reduction in negative outcomes as compared to those who receive usual care. In this setting, usual care consists of basic quantity and frequency questions asked inconsistently as part of the admission process and varying by provider, with no standardized approach to screening, treatment, follow-up, or referral.

Female
Portland, OR

The purpose of the study is to learn more about menstrual changes in progestin contraception users. The investigators are hoping to find out what changes in the endometrium lead to different bleeding patterns during the first year of progestin contraception use. Participants will choose to receive the contraceptive implant (Etonogestrel implant also called Nexplanon) or the contraceptive injectable (Depo-medroxyprogesterone acetate (DMPA) also called Depo-Provera) for up to 12 months. They will be asked to have 4 endometrial biopsies over the course of the study, as well as blood draws, physical exams, and pregnancy tests. Participants will also use a daily text message or email diary to report bleeding patterns. This study's plan is to comprehensively phenotype bleeding patterns and profile the entire endometrium using single-cell RNA seq data (sCRNAseq).
