However atorlip-5 5mg discount, experimental studies that simulate athletic events can fnd no adverse efects on oxygen uptake or respiratory rate. In athletes who wish to avoid menstrual bleeding, oral contraceptives can be administered on a daily basis, with no breaks, preventing withdrawal bleeding. The Noncontraceptive Benefits of Oral Contraception The noncontraceptive benefts of low-dose oral contraception can be grouped into two main categories: benefts that incidentally accrue when oral contra- ception is specifcally utilized for contraceptive purposes and benefts that result from the use of oral contraceptives to treat problems and disorders. Of course, pre- vention of benign and malignant neoplasia is an outstanding feature of oral contraception. A 40% reduction in ovarian cancer and a 50% reduction in endometrial cancer represent substantial protection. In the Oxford Family Planning Association cohort, the use of low-dose oral contraceptives was associated with a declining incidence of benign breast disease with increas- ing duration of use. The low-dose contraceptives are as efective as higher dose prepa- rations in reducing menstrual fow and the prevalence and severity of dysmenorrhea. By 1960, 500,000 women were using these agents, although it is unlikely that all had endometriosis or even dysmenorrhea. Terefore, there is an enormous clinical history supporting the use of oral contracep- tives for the treatment of endometriosis. A Japanese double-blind, placebo-controlled, randomized multicenter trial evaluated the use of a low-dose oral contraceptive for the treatment of dysmenorrhea associated with endometriosis. Dysmenorrhea pain interestingly decreased in the placebo group, but the decrease in the oral contraceptive group was about twice as great. The treatment group demonstrated a decrease in pelvic indu- ration that did not achieve statistical signifcance. Only the treated group demonstrated a reduction in the size of ovarian endometriomas that were larger than 3 cm diameter at baseline. This Japanese study provides clinical trial data for a low-dose oral contraceptive that confrms years of experi- ence. It is worth noting that a randomized, placebo-controlled trial using a 20 mg estrogen oral contraceptive has documented efective treatment of primary dysmenorrhea in adolescents. Unfortunately, these two beliefs are derived from his- torical experience and reported in the literature as uncontrolled studies. But it is unlikely that randomized trials will address these two points, and until such studies are available, there is no valid reason to discount many years of clinical experience. In an Italian prospective study (but not a random- ized trial), women experiencing recurrent dysmenorrhea associated with endometriosis while being treated with a cyclic oral contraceptive regimen improved when switched to a daily, continuous dosing regimen with a 20 mg oral contraceptive. Another advantage of oral contracep- tive treatment is that endometriosis may be associated with a slight increase in ovarian cancer (as well as adenocarcinoma in endometriosis tissue), and the profound reduction in the risks of ovarian and endometrial cancer A Clinical Guide for Contraception well demonstrated in women without endometriosis is observed equally in women with endometriosis. Retrospective studies indicated a reduction in fractures in postmenopausal women who had previously used oral contraceptives. In contrast, a case-control study from Sweden found a reduction in the risk of postmenopausal hip fractures when oral contraceptives (mostly older high-dose products) were used afer age 40 by women who were not overweight, with an increasing beneft with increasing duration of use. Future studies of postmenopausal women should eventually reveal the accurate relationship between oral con- traceptive use and osteoporotic fractures. The literature on rheumatoid arthritis has been controversial, with stud- ies in Europe fnding evidence of protection and studies in North America failing to demonstrate such an efect. An excellent Danish case-control study was designed to answer criticisms of shortcomings in the previous literature. One meta-analysis concluded that the evidence con- sistently indicated a protective efect, but that rather than preventing the development of rheumatoid arthritis, oral contraception may modify the course of disease, inhibiting the progression from mild to severe disease, whereas a later meta-analysis concluded there was no evidence of a pro- tective efect. Oral contraceptives have been a cornerstone for the treatment of anovulatory, dysfunctional uterine bleeding; the only randomized, placebo-controlled trial documented the benefcial impact long recognized by clinicians. Comparison studies with oral contra- ceptives containing these progestins can detect no diferences in efects on various androgen measurements among the various products or when com- pared with older products. Oral contraceptives have long been used to speed the resolution of ovarian cysts, but the efcacy of this treatment has not been established. Randomized trials have been performed with women who develop ovar- ian cysts afer induction of ovulation. Of course, these were functional cysts secondary to ovulation induction, and this experience may not apply to spontaneously appearing cysts. Two short-term (5 and 6 weeks) randomized studies could document no greater efect of oral contraceptive treatment on resolution of spontaneous ovarian cysts when compared with expectant management. Despite the fact that oral contraception is highly efective, hundreds of thou- sands of unintended pregnancies occur each year in the United States because of the failure of oral contraception. In general, the most important determinants of pill failure are age, intention toward a future birth, par- ity, and marital status. Interestingly, once these factors are accounted for, duration of use, race, ethnicity, and poverty status no longer afected the risk of pill failure. Noncompliance includes a wide variety of behavior: failure to fll the initial prescription, failure to continue on the medication, and incorrectly taking oral contraception. Compliance (continuation) is an area in which personal behavior, biology, and pharmacology come together. Unfortunately, women who discontinue oral contraception ofen utilize a less efective method or, worse, fail to substitute another method. The experience of side efects, such as breakthrough bleeding and amenorrhea, and perceived experience of “minor” problems, such as headaches, nausea, breast tenderness, and weight gain. Fears and concerns regarding cancer, cardiovascular disease, and the impact of oral contraception on future fertility. Nonmedical issues, such as inadequate instructions on pill taking, complicated pill packaging, difculties arising from the patient pack- age insert, and most importantly, contraceptive access and expense. The information in this chapter is the foundation for good continuation, but the clinician must go beyond the presentation of information and develop an efective means of communicating that information. We recommend the following approach to the clinician-patient encounter as one way to improve continuation with oral contraception. Review briefy the risks and benefts of oral contraception, but be care- ful to put the risks in proper perspective, and to emphasize the safety and noncontraceptive benefts of low-dose oral contraceptives. Review the side efects that can afect continuation: amenorrhea, break- through bleeding, headaches, weight gain, nausea, etc. Explain the warning signs of potential problems: abdominal or chest pain, trouble breathing, severe headaches, visual problems, leg pain, or swelling.
