Indications & Usage
INDICATIONS AND USAGE Cyonanz TM tablets are indicated for the prevention of pregnancy in women who elect to use this product as a method of contraception. Oral contraceptives are highly effective. Table 1 lists the typical accidental pregnancy rates for users of combined oral contraceptives and other methods of contraception. The efficacy of these contraceptive methods, except sterilization, the IUD, and the NORPLANT ® System depends upon the reliability with which they are used. Correct and consistent use of methods can result in lower failure rates. Table 1: Percentage of Women Experiencing an Unintended Pregnancy During the First Year of Typical Use and the First Year of Perfect Use of Contraception and the Percentage Continuing Use at the End of the First Year. United States. Adapted from Hatcher et al., 1998, Ref. #1. Emergency Contraceptive Pills: Treatment initiated within 72 hours after unprotected intercourse reduces the risk of pregnancy by at least 75%. § Lactational Amenorrhea Method: LAM is a highly effective, temporary method of contraception. ¶ Source: Trussell J. Contraceptive efficacy. In Hatcher RA, Trussell J, Stewart F, Cates W, Stewart GK, Kowal D, Guest F. Contraceptive Technology: Seventeenth Revised Edition. New York, NY: Irvington Publishers, 1998. * Among couples attempting to avoid pregnancy, the percentage who continue to use a method for one year. † Among typical couples who initiate use of a method (not necessarily for the first time), the percentage who experience an accidental pregnancy during the first year if they do not stop use for any other reason. ‡ Among couples who initiate use of a method (not necessarily for the first time) and who use it perfectly (both consistently and correctly), the percentage who experience an accidental pregnancy during the first year if they do not stop use for any other reason. § The treatment schedule is one dose within 72 hours after unprotected intercourse, and a second dose 12 hours after the first dose. The Food and Drug Administration has declared the following brands of oral contraceptives to be safe and effective for emergency contraception: Ovral ® (1 dose is 2 white pills), Alesse ® (1 dose is 5 pink pills), Nordette ® or Levlen ® (1 dose is 2 light-orange pills), Lo/Ovral ® (1 dose is 4 white pills), Triphasil ® or Tri-Levlen ® (1 dose is 4 yellow pills). ¶ However, to maintain effective protection against pregnancy, another method of contraception must be used as soon as menstruation resumes, the frequency or duration of breastfeeds is reduced, bottle feeds are introduced, or the baby reaches six months of age. # The percents becoming pregnant in columns (2) and (3) are based on data from populations where contraception is not used and from women who cease using contraception in order to become pregnant. Among such populations, about 89% become pregnant within one year. This estimate was lowered slightly (to 85%) to represent the percent who would become pregnant within one year among women now relying on reversible methods of contraception if they abandoned contraception altogether.

Dosage & Administration
DOSAGE AND ADMINISTRATION To achieve maximum contraceptive effectiveness, Cyonanz TM Tablets must be taken exactly as directed and at intervals not exceeding 24 hours. Cyonanz TM Tablets are available with the blister pack which is preset for a Sunday Start. Day 1 Start stickers are also provided. NOTE: Each cycle pack is preprinted with the days of the week, starting with Sunday, to facilitate a Sunday start regimen. Six different “day label strips” are provided with each cycle pack in order to accommodate a Day 1 start regimen. In this case, the patient should place the self-adhesive “day label strip” that corresponds to her starting day over the preprinted days. Sunday Start When taking Cyonanz TM , the first “active” tablet should be taken on the first Sunday after menstruation begins. If the period begins on Sunday, the first “active” tablet should be taken that day. Take one active tablet daily for 21 days followed by one green “reminder” tablet daily for 7 days. After 28 tablets have been taken, a new course is started the next day (Sunday). For the first cycle of a Sunday Start regimen, another method of contraception such as a condom or spermicide should be used until after the first 7 consecutive days of administration. If the patient misses one (1) “active” tablet in Weeks 1, 2, or 3, the tablet should be taken as soon as she remembers. If the patient misses two (2) “active” tablets in Week 1 or Week 2, the patient should take two (2) tablets the day she remembers and two (2) tablets the next day; and then continue taking one (1) tablet a day until she finishes the pack. The patient should be instructed to use a back-up method of birth control such as a condom or spermicide if she has sex in the seven (7) days after missing pills. If the patient misses two (2) “active” tablets in the third week or misses three (3) or more “active” tablets in a row, the patient should continue taking one tablet every day until Sunday. On Sunday the patient should throw out the rest of the pack and start a new pack that same day. The patient should be instructed to use a back-up method of birth control if she has sex in the seven (7) days after missing pills. Complete instructions to facilitate patient counseling on proper pill usage may be found in the Detailed Patient Labeling ( “How to Take the Pill” section). Day 1 Start The dosage of Cyonanz TM , for the initial cycle of therapy, is one “active” tablet administered daily from the 1st through the 21st day of the menstrual cycle, counting the first day of menstrual flow as “Day 1” followed by one green “reminder” tablet daily for 7 days. Tablets are taken without interruption for 28 days. After 28 tablets have been taken, a new course is started the next day. If the patient misses one (1) “active” tablet in Weeks 1, 2, or 3, the tablet should be taken as soon as she remembers. If the patient misses two (2) “active” tablets in Week 1 or Week 2, the patient should take two (2) tablets the day she remembers and two (2) tablets the next day; and then continue taking one (1) tablet a day until she finishes the pack. The patient should be instructed to use a back-up method of birth control such as a condom or spermicide if she has sex in the seven (7) days after missing pills. If the patient misses two (2) “active” tablets in the third week or misses three (3) or more “active” tablets in a row, the patient should throw out the rest of the pack and start a new pack that same day. The patient should be instructed to use a back-up method of birth control if she has sex in the seven (7) days after missing pills. Complete instructions to facilitate patient counseling on proper pill usage may be found in the Detailed Patient Labeling ( “How to Take the Pill” section). The use of Cyonanz TM for contraception may be initiated 4 weeks postpartum in women who elect not to breastfeed. When the tablets are administered during the postpartum period, the increased risk of thromboembolic disease associated with the postpartum period must be considered. (See CONTRAINDICATIONS and WARNINGS concerning thromboembolic disease. See also PRECAUTIONS: Nursing Mothers . ) The possibility of ovulation and conception prior to initiation of medication should be considered. (See Discussion of Dose-Related Risk of Vascular Disease from Oral Contraceptives .) ADDITIONAL INSTRUCTIONS Breakthrough bleeding, spotting, and amenorrhea are frequent reasons for patients discontinuing oral contraceptives. In breakthrough bleeding, as in all cases of irregular bleeding from the vagina, nonfunctional causes should be borne in mind. In undiagnosed persistent or recurrent abnormal bleeding from the vagina, adequate diagnostic measures are indicated to rule out pregnancy or malignancy. If pathology has been excluded, time or a change to another formulation may solve the problem. Changing to an oral contraceptive with a higher estrogen content, while potentially useful in minimizing menstrual irregularity, should be done only if necessary since this may increase the risk of thromboembolic disease. Use of oral contraceptives in the event of a missed menstrual period: If the patient has not adhered to the prescribed schedule, the possibility of pregnancy should be considered at the time of the first missed period and oral contraceptive use should be discontinued if pregnancy is confirmed. If the patient has adhered to the prescribed regimen and misses two consecutive periods, pregnancy should be ruled out.
Warnings & Precautions
WARNING: CARDIOVASCULAR RISK ASSOCIATED WITH SMOKING Cigarette smoking increases the risk of serious cardiovascular events from combination oral contraceptive use. This risk increases with age, particularly in women over 35 years of age, and with the number of cigarettes smoked. For this reason, combination oral contraceptives, including Cyonanz TM , should not be used by women who are over 35 years of age and smoke.

Post Marketing Experience Five studies that compared breast cancer risk between ever-users (current or past use) of COCs and never-users of COCs reported no association between ever use of COCs and breast cancer risk, with effect estimates ranging from 0.90 to 1.12 (Figure 2). Three studies compared breast cancer risk between current or recent COC users (<6 months since last use) and never users of COCs (Figure 2). One of these studies reported no association between breast cancer risk and COC use. The other two studies found an increased relative risk of 1.19 to 1.33 with current or recent use. Both of these studies found an increased risk of breast cancer with current use of longer duration, with relative risks ranging from 1.03 with less than one year of COC use to approximately 1.4 with more than 8 to 10 years of COC use.
