Quasense tablets are indicated for the prevention of pregnancy in women who elect to use oral contraceptives as a method of contraception.
In a 1-year controlled clinical trial, 4 pregnancies occurred in women 18-35 years of age during 809 completed 91-day cycles of Quasense during which no backup contraception was utilized. This represents an overall use-efficacy (typical user efficacy) Pregnancy rate of 1.98 per 100 women-years of use.
Oral contraceptives are highly effective for pregnancy prevention. Table 2 lists the typical unintended pregnancy rates for users of combination oral contraceptives and other methods of contraception. The efficacy of these contraceptive methods, except sterilization, the IUD, and Norplant® Implant System, depends upon the reliability with which they are used. Correct and consistent use of methods can result in lower failure rates.
TABLE II: 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. % of Women Experiencing anUnintended Pregnancy within the First Year of Use % of Women Continuing Use at One Year 3 Method Typical Use 1 Perfect Use 2 (1) (2) (3) (4) 1 Among typical couples who initiate use of a method (not necessarily for the first time), the percentage who experience an unintended pregnancy during the first year if they do not stop use for any other reason. 2 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 unintended pregnancy during the first year if they do not stop use for any other reason. 3 Among couples attempting to avoid pregnancy, the percentage who continue to use a method for one year. 4 The percentages of women 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 percentage who would become pregnant within one year among women now relying on reversible methods of contraception if they abandoned contraception altogether. 5 Foams, creams, gels, vaginal suppositories and vaginal film. 6 Cervical mucus (ovulation) method supplemented by calendar in the pre-ovulatory and basal body temperature in the post-ovulatory phases. 7 With spermicidal cream or jelly. 8 Without spermicides. 9 The treatment schedule is one dose within 72 hours after unprotected intercourse and a second dose 12 hours after the first dose.
