How do I get started using birth control? If using the ring Start a new ring and note what day of the month it is the first day of the month might be easiest to remember. For example, you may decide that your change date is the first of every month. You would take out the old ring and put a new one in on January 1 st , February 1 st , March 1 st.
If using birth control pills You can switch to a pill brand that is designed in an extended or continuous fashion. You can also have less frequent periods with regular monthly pills. First, figure out which pills are the placebos. There are usually seven of them at the end of the pack, and they are a different color than the active pills. Ask your health provider or your pharmacist if you are not sure! Second, decide how often you want to have a period: To have a period every 63 days, take 63 active pills in a row.
Antibiotics do not interfere with the effectiveness of birth control pills — except in the case of one antibiotic, rifampin Rimactane. Rifampin does decrease the effectiveness of birth control pills in preventing ovulation, but this antibiotic isn't widely used today.

The largest study of continuous OCP users evaluated women, 19 of whom became pregnant during the 1-year study period.
Fifteen of these pregnancies were attributed to method failure Archer et al Another large study randomized women to cyclic or continuous use for one year Coutinho et al Two smaller studies randomizing cyclic and continuous use OCPs demonstrated no pregnancies in either group during the study period Miller and Hughes ; Kwiecien et al The most commonly reported side effect with continuous or extended regimen OCP dosing is breakthrough vaginal bleeding.
Studies evaluating this side effect have reported its presence to varying degrees. In a large trial of continuous oral contraceptives, patients A Cochrane review evaluated 6 randomized controlled trials with extended or continuous OCPs Edelman et al Although the differences between the medications and duration of the studies limited comparison between trials, the authors concluded that bleeding patterns were either equivalent or improved with the extended or continuous dosing regimen.
The extended or continuous cycle groups also fared better with respect to headaches, genital irritation, tiredness, bloating, and menstrual pain in the studies that evaluated these side effects. There were no overall differences observed in contraceptive efficacy, safety profiles, compliance, discontinuation rates or patient satisfaction between cyclic and continuous users. Amenorrhea rates for the 3 largest studies are summarized in Table 1.
Collectively these data indicate that most patients on continuous OCPs will obtain amenorrhea after 1 year of treatment but the exact incidence is difficult to quantify given the slightly different hormonal regimens used by each study. Additionally, the incidence of breakthrough bleeding and spotting is initially high with continuous dosing but appears to decrease consistently over time.
Whether amenorrhea rates would continue to increase after one year of treatment is uncertain because no studies have evaluated treatment beyond one year.
The total number of bleeding days is less with continuous dosing than with traditional cyclic dosing although the timing of bleeding with continuous dosing will not typically occur at predictable intervals.
Finally, the incidence of vaginal spotting was either increased or unchanged with continuous dosing in studies comparing continuous to traditional cyclic dosing Miller and Notter ; Kwiecien et al ; Archer et al Amenorrhea rates in users of continuous oral contraceptives containing levonorgesterel in 3 large studies each pill pack contained a day supply.
Although breakthrough bleeding is a temporary problem for some women on continuous OCPs, providers can reassure women that this bleeding does not demonstrate an endometrial abnormality. Studies evaluating endometrial histology on continuously dosed OCPs have found reassuring results.
Endometrial biopsies were performed at baseline and after at least 6 months of treatment. Only 3 subjects had proliferative endometrim with continuous OCP use.
No endometrial hyperplasia or malignancy was found in any biopsy specimen. No endometrial hyperplasia or malignancy was identified. The resumption of menses after discontinuation of continuous OCPs has been shown to occur within 60 days for This supports the theory that continuous OCPs, as with cyclic dosing, provides an effective and immediately-reversible contraceptive option for women.
As expected with oral contraceptives, a modest number of subjects reported adverse effects with continuous OCPs in the Phase 3 trial such as abdominal pain 9. Bothersome uterine bleeding caused Rare serious adverse events included two subjects with cholecystitis, one thrombotic event, one ectopic pregnancy, one prolonged uterine bleeding, and one enlarged uterine fibroids Archer et al OCPs have several known metabolic effects including increased production of clotting factors resulting in increased risk of venous thromboembolism, increased gallstone formation during the first year of use, and increased risk of liver adenomas Speroff and DeCherney Limited information is available on the metabolic effects of continuous or extended OCPs.
One small study randomized 30 women to a cyclic versus extended regimen and found no differences in liver proteins, lipoproteins, and hemostatic variables at 0, 3, and 12 months Cachrimanidou et al The small increased temporal exposure to synthetic hormones, associated with extended or continuous OCP use, is unlikely to result in significant metabolic differences compared with traditional cyclic administration.
Clearly, extended and continuous oral contraceptives are effective in lessening menstrual bleeding, but these medications may also lessen other menstrual symptoms. Table 2 summarizes menstrual conditions that may be improved with extended or continuous cycle OCPs.
Several studies have evaluated the utility of extended and continuously dosed OCPs for reducing menstrual symptoms including dysmenorrhea and pre-menstrual symptoms. Conditions that may be improved with continuous and extended cycle oral contraceptives. In addition to lessening menstrual symptoms, continuous oral contraceptives may be effective at reducing symptoms related to other gynecologic conditions such as ovarian cysts, pelvic pain, and endometriosis.
Continuous OCPs effectively suppress ovarian activity and ovulation as evidenced by one study in which An Italian study evaluated continuously dosed OCPs as a treatment for dysmenorrhea associated with endometriosis Vercellini et al This study evaluated women with surgically treated endometriosis who had persistent dysmenorrhea on cyclic OCPs.
Studies indicate that regularly cycling women are interested in reducing the frequency of menstruation. A Dutch telephone survey evaluating attitudes towards menstruation in reproductive aged women demonstrated that Most of the menstruating women in all age groups preferred to have a bleeding frequency of less than once a month or never, and this result was more significant in older women and in women using OCPs den Tonkelaar and Oddens Women who preferred fewer menses reported a desire for fewer severe menstrual complaints, better hygiene, higher quality of life, and less blood loss.
Women who preferred monthly bleeding cited concerns such as fear of pregnancy, infertility and adverse events and a belief that menstruation is natural Wiegratz et al For some careers, the cessation of menses is advantageous for women. Any job which limits hygiene, such as active-duty military, may be simplified by reducing menses. Despite relatively high patient drop-out rates in some studies evaluating extended regimen and continuous OCPs, high patient satisfaction has been consistently reported.
Another study evaluating an extended regimen showed that most patients rated their overall satisfaction with the extended cycle OCP regimen as good to excellent and stated they would choose to have fewer menstrual periods after the completion of the study Anderson and Hait For continuous use OCPs, patient satisfaction is as high as with cyclic users; Similarly, Clinical experience and study surveys indicate that some women prefer to have monthly withdrawal bleeding to provide reassurance that they are not pregnant.
Appropriate counseling on the contraceptive efficacy of continuously dosed OCPs would likely reassure many of these patients. Pregnancy tests can certainly be offered to patients on continuous OCPs; however, many other contraceptive methods cause menstrual irregularity or suppression and routine pregnancy tests are not medically indicated for these patients.
