Millions of women in the United States use some type of hormonal contraception: combination oral contraceptive pills (OCPs), progestin-only pills, medroxyprogesterone acetate injections, or subdermal levonorgestrel implants. Abnormal uterine bleeding is a common but rarely dangerous side effect of hormonal contraception. It is, however, a major cause for the discontinuation of hormonal contraception and the resultant occurrence of unplanned pregnancy. The evaluation of abnormal uterine bleeding in women who are using hormonal contraception includes an assessment of compliance, a thorough history and complete physical examination to exclude organic causes of bleeding, and a targeted laboratory evaluation. Pregnancy and the misuse of OCPs are frequent causes of abnormal uterine bleeding. Bleeding is common during the first three months of OCP use; counseling and reassurance are adequate during this time period. If bleeding persists beyond three months, it can be treated with supplemental estrogen and/or a
Evidence on the association between antibiotic use and combination oral contraceptive (COC) failure remains controversial, with recent studies reporting no evidence to support decreased effectiveness of birth control with the use of antibiotics except rifampin and rifabutin.. However, some doctors will ask an oral contraceptive user to use additional protection while using an antibiotic. The reasoning that antibiotics might interfere with the effectiveness of COCs revolves around the antibiotic decreasing steroid hormones plasma concentrations by hepatic microsomal enzyme induction or inhibition, interference with enterohepatic circulation of COC metabolites, interference with absorption from the GI tract, competition between two drugs for the same metabolizing enzyme, alterations in plasma protein binding, induction of an opposite physiologic effect, or increased urinary or fecal excretion of the contraceptive.. The strongest evidence is for rifabutin and rifampin: a significant decrease in ...
In December 1976, the federal FDA proposed mandatory patient package inserts accompany all pill prescriptions: "The Food and Drug Administration will regard as misbranded and subject to regulatory action any oral contraceptive that is shipped in interstate commerce … after April 6, 1977 without labeling that is substantially the same as set forth in this notice." Thus, the FDA required pill manufacturers to tell physicians that the pill included a mode of action that every physician would understand from his medical training to be an early abortion: "Combination oral contraceptives … Although the primary mechanism of action is inhibition of ovulation, alterations … in the endometrium (which reduce the likelihood of implantation) may also contribute to contraceptive effectiveness … progestin oral contraceptives are known to … exert a progestational effect on the endometrium, interfering with implantation, and, in some patients suppress ovulation."16. Physician package inserts for the ...
Many women and physicians believe that a common side effect of combination oral contraceptive pills (OCPs) and contraceptive patches is weight gain. This is the most common reason for not initiating the use of combination OCPs or patches, or for discontinuing their use at an early stage. However, the association between combination OCPs and weight gain has not been scientifically established. In fact, women who stop using combination OCPs may be more likely to gain weight than those who continue to use them. Gallo and colleagues studied the association between the use of combination OCPs and patches and weight changes.. To identify randomized controlled trials (RCTs) of combination OCPs or patches that included data on weight changes, the authors searched relevant databases and contacted appropriate study investigators and combination OCP and patch manufacturers. RCTs were included if they were of good quality and covered at least three treatment cycles. Data were abstracted from eligible trials ...
So, what makes one combination oral contraceptive pill (OCP) different from another? Whats the difference between brand-name and generic versions, if any? The answer generally boils down to one word: progesterone. How do we know this? Because the chemical composition of the estrogen component of almost every OCP marketed in the U.S. is exactly the same. Its ethinyl estradiol. …
Women using a vaginal ring or skin patch for contraception are at around double the risk of a blood clot compared to those taking the Pill," the Daily Mail has reported. The news is based on a large Danish study that looked at contraceptive use in more than 1.5 million women. The study looked at how different hormone-based methods such as implants, the patch and the pill related to the risk of blood clots. Between 2001 and 2010 researchers recorded a total of 3,434 blood clots, also known as venous thromboembolisms or VTE. The background rate of VTE among women not using hormonal contraception was 2.1 per 10,000 woman-years (for example, 2.1 would occur if 1,000 women were followed for 10 years). The highest rate of VTE was among women who used the contraceptive patch, with 9.7 per 10,000 woman-years. Women using a common oral contraceptive pill experienced a rate of 6.2 per 10,000 woman-years.. Despite what some news coverage might suggest, hormonal contraceptives containing oestrogen ( the ...
What causes bleeding two days after suddenly stopping birth control? If a woman missed a pill, or has decided to stop taking birth control pills, she may experience bleeding as an effect of skipping pills. Bleeding that occurs during the pill-free intervals of seven days is called withdrawal bleeding, and this is quite normal. Withdrawal bleeding is the expected outcome of taking the inactive or placebo pills, taken after the 21-day active pills, and before starting with a new cycle. Missing a pill can also cause bleeding (breakthrough bleeding) because this causes the endometrium to lose its consistency that was built up during the days of on-time taking of the pill.
Oral contraceptives, abbreviated OCPs, also known as birth control pills, are medications taken by mouth for the purpose of birth control. Two types of female oral contraceptive pill, taken once per day, are widely available: The combined oral contraceptive pill contains estrogen and a progestin The progestogen-only pill Ormeloxifene is a selective estrogen receptor modulator which offers the benefit of only having to be taken once a week. Emergency contraception pills ("morning after pills") are taken at the time of intercourse, or within a few days afterwards: Levonorgestrel, sold under the brand name Plan B Ulipristal acetate Mifepristone and misoprostol, when used in combination, are more than 95% effective during the first 50 days of pregnancy. The combination is administered by a physician, and is only used as a last resort Male oral contraceptives are currently not available commercially, although several possibilities are in various stages of research and ...

Oral contraceptives are medicines taken by mouth to help prevent pregnancy. Also known as birth control pills, they contain artificially made forms of twohormones produced naturally in the body. These hormones, estrogen and progestin, regulate a womans menstrual cycle. When taken in the proper amounts, following a specific schedule, oral contraceptives are very effective in preventing pregnancy.. Oral contraceptives have several effects that help prevent pregnancy. For pregnancy to occur, an egg must ripen inside a womans ovary, be released, and travel to the fallopian tube (the passageway from the ovary to the uterus). Amans sperm must also reach the fallopian tube, where it fertilizes the egg.Then the fertilized egg must travel to the womans uterus (womb), where it lodges in the uterus lining and develops into a fetus. The main way that oral contraceptives prevent pregnancy is by keeping an egg from ripening fully. Eggs that do not ripen fully cannot be fertilized. In addition, birth ...
To the editor: Horwitz and Feinstein (1) conclude from their epidemiologic study of endometrial cancer that "no association exists between the use of oral contraceptive pills and the subsequent development of endometrial cancer." They correctly point out that a limitation of their data is that only a small number of patients and control subjects had previously used contraceptive pills. Their data may also be limited by the relatively short time from the introduction of contraceptive pills to the present. A typical latent period from exposure to known chemical carcinogens until detection of cancer is 20 to 40 years (2-4). Oral ...
Approximately 11.6 million women in the United States use oral contraceptives (OCs) each year. The vast majority of OCs combine both estrogen and a type of progestin, or progesterone-like substance into one pill which is taken daily. Depression or a negative change in mood, apparently resulting from the use of OCs, is thought to be one of the main reasons women miss pills or stop taking their oral contraceptive pills (OCPs) altogether. Clinical observation that some women develop depression when taking progestin only OCs or when adding progestins to menopausal estrogen therapy has led to the speculation that the progestin is the likely culprit of these negative mood changes in women using combined OCPs.. The current study is designed to investigate the role of progestins in the development of mood symptoms in OCP users. Women participating in this study will receive one of two different OCPs for three months. Their mood while taking the OCPs will be compared to their mood prior to using OCPs. In ...
According to a Harvard University Study, women may be three times more likely to develop Crohns disease if they have used oral contraceptive pills for five years or more. The risk was especially pronounced in women who already had a genetic predisposition to chronic gastrointestinal disease.. While "the pill" is widely used and highly effective in preventing pregnancy, it has adverse effects.. The study involved 232,452 American women with no prior history of ulcerative colitis (UC) or Crohns disease (CD) from 1976 to 2008. They found 315 cases of CD and 392 cases of UC.. The results of the study were such that compared with women who had never used oral contraceptives, current users had a 2.82 multivariate-adjusted hazard ratio for CD. For past users, the hazard ratio was 1.39.. Reflecting on the strong association between use of oral contraceptives and CD, the authors note that, "After adjusting for known or potential risk factors for CD, including BMI, smoking, hormone use, age at menarche, ...

Oral contraceptives pass into the breast milk and can change the content or lower the amount of breast milk. Also, they may shorten a womans ability to breast-feed by about 1 month, especially when the mother is only partially breast-feeding. Because the amount of hormones is so small in low-dose contraceptives, your doctor may allow you to begin using an oral contraceptive after you have been breast-feeding for a while. However, it may be necessary for you to use another method of birth control or to stop breast-feeding while taking oral contraceptives.. ...
Objectives: Oral contraceptives (OCP) are highly effective, safe and widely used. Higher exposure to endogenous and exogenous estrogens is generally thought to increase the risk of breast cancer. Therefore, this study was conducted to determine if oral contraceptive use affected the expression of CA 15-3, CEA and C-erb B-2 in the saliva of healthy women. Study design: The participants consisted of 87 healthy women (43 controls and 44 using oral contraceptives) ranging in age from 20 to 54 years. The volunteers participated by giving one ? time stimulated whole saliva samples. Then the samples were analysed for CA 15-3, CEA and C-erb B-2 concentrations. Results: The student t-test was used to compare group means for variables with comparable variability. The mean of C-erb B-2, CEA, and CA 15-3 concentrations (in the case and control groups) was (1.93, 1.70), (34.46, 31.62) and (12.58, 16.19) respectively. These differences were not statistically significant. Conclusions: Our findings suggest that ...

These results suggest that many women who are using oral contraceptives in their peak bone-development years could reduce their risk of osteoporosis by approximately 3 percent to 10 percent over one year by making sure they get enough calcium in their diet," Teegarden said. "This demonstrates the importance of calcium intake, either by getting enough dairy or with supplements." ...
Follicle stimulating hormone and luteinizing hormone are produced by the pituitary gland which is located at the base of the brain. These two hormones coordinate the development and release of an egg from the ovary. A surge in both of these hormones ordinarily occurs in the middle of a womans menstrual cycle.. Follicle stimulating hormone stimulates ovarian egg production. Luteinizing hormone triggers egg released from the ovary: ovulation. Oral contraceptive pills inhibit the production of both follicle stimulating hormone and luteinizing hormone; as such oral contraceptive pills prevent ovulation.. Another contraceptive mechanism of (combined) birth control pills is to prevent fertilization. Combined oral contraceptives effect cervical secretions. The progestin contained in the birth control pill causes the cervical secretion to thicken which impedes sperm, little or no sperm enter the uterine cavity; as such fertilization cannot occur.. Oral contraceptives do not terminate a pregnancy, they ...

Birth control pills (BCPs) are both the most effective and the most hazardous form of contraception. Preventing pregnancy in this way is done by taking an oral dose of a combination of the hormones estrogen and progestin (synthetic progesterone) in amounts higher than the body?s natural levels. This prevents the pituitary hormones that stimulate ovulation and fertilization of the egg from being released, and thus prevents pregnancy. Though taking oral contraceptives regularly is 99 percent effective in birth control, there are many possible side effects. Weight gain, emotional swings, circulatory and vascular symptoms, and gastrointestinal upset are not uncommon. Blood clots, liver problems, and cancer are also possible, though relatively rare; these were more common in the 1960s with the higher-dose pills. Many women have difficulty with oral contraceptives, though many others seem to tolerate them well. The use of birth control pills is more common in young women and teenagers, which adds ...
Women who take the contraceptive pill for ten years almost halve their risk of being diagnosed with ovarian cancer, according to a new study.. But experts say this must be balanced against the risk of breast cancer, which is higher in women on the pill.. For every 100,000 women on the Pill for 10 years there are 50 extra breast cancers and 12 fewer ovarian cancers, data shows.. "Women may be reassured to know that the oral contraceptive is not only an effective contraceptive but can have the added benefit of reducing their risk of ovarian cancer," the BBC quoted Dr Richard Edmondson of the Northern Institute for Cancer Research at the University of Newcastle, as saying.. "These results are important because most women dont know that taking the Pill or getting pregnant can help reduce their risk of ovarian cancer later on in life," he added.. The study followed more than 300,000 women enrolled in a large European study known as EPIC (European Prospective Investigation of Cancer).. The women were ...
Oral contraceptives (birth control pills). Medications taken daily that prevent ovulation by controlling pituitary hormone secretion. Usually, oral contraceptives contain the hormones estrogen and progestin. In addition to prevention of pregnancy, oral contraceptives have several health benefits including regulating menstrual cycles and decreasing the amount and length of menstrual periods. This can help increase iron stores in women with iron deficiency associated with excessive bleeding. Prevention of certain ovarian and endometrial cancers is a significant benefit of the use of oral contraceptives. Some research has found that some benign (noncancerous) breast diseases, including fibroadenoma and cystic changes, occur less frequently with the use of oral contraceptives. Recent studies have also suggested that oral contraceptive use may reduce the occurrence of severe disabling rheumatoid arthritis.. ...

Using referred controls-persons who were initially suspected of having the same disease as the case patients-in a case-control study is not always a mistake; it can be a good strategy for ruling out diagnostic suspicion or referral bias, as exemplified by the association between oral contraceptive use and VT. Suppose that oral contraceptives would not cause VT, contrary to physicians beliefs. If a young woman presented with signs and symptoms of VT, knowing that she used oral contraceptives would sway her physician to refer her for diagnostic work-up, whereas the physician might not have referred her otherwise because thrombosis is unlikely in young women (2). Case-control studies enroll patients according to the diagnosis they receive and would thereby show a spurious association between oral contraceptives and VT because more case patients than controls would be using oral contraceptives. This hypothetical situation exemplifies the influence of diagnostic suspicion bias in case-control ...

There is interesting research around blobbing and contraception where randomised controlled trials have been conducted on extended oral contraceptive cycles. The fact that most women on OC take the pills in 21 days followed by a pill-free and bleeding week is not medically necessary. Women can stay on OC pretty much permanently with minimal spotting and few ill effects over the general OC side effects and recommendations for use over time (i.e limit to 8 years [pdf]). And yet many choose, if made aware of the choice, to allow for a pill-free period if not monthly than every three or so months. This suggests that there may be a desire to menstruate which may be for a number of reasons: confirming no pregnancy, excuse for not having sex, the ancient Greek feeling of menstrual catharsis ...

Drospirenone is a synthetic progestin that is an analog to spironolactone. It is found in a number of birth control formulations. Drospirenone differs from other synthetic progestins in that its pharmacological profile in preclinical studies shows it to be closer to the natural progesterone. As such it has anti-mineralocorticoid properties, counteracts the estrogen-stimulated activity of the renin-angiotensin-aldosterone system, and is not androgenic. It was shown in animal studies that drospirenone exhibits antiandrogenic activity judging from accessory sex gland growth in castrated, androgen-treated, juvenile rats.
