Oral contraceptives are highly effective. Table I lists the typical accidental pregnancy rates for users of combination oral contraceptives and other methods of contraception.1 The efficacy of these contraceptive methods, except sterilization, depends upon the reliability with which they are used. Correct and consistent use of methods can result in lower failure rates.

DOSAGE AND ADMINISTRATION
To achieve maximum contraceptive effectiveness, oral contraceptives must be taken exactly as directed and at intervals not exceeding 24 hours.
For a DAY 1 START, count the first day of menstrual flow as Day 1 and the first tablet (white) is then taken on Day 1. For a SUNDAY START when menstrual flow begins on or before Sunday, the first tablet (white) is taken on that day. With either a DAY 1 START or SUNDAY START, 1 tablet (white) is taken each day at the same time for 21 days. Then the peach tablets are taken for 7 days, whether bleeding has stopped or not. After all 28 tablets have been taken, whether bleeding has stopped or not, the same dosage schedule is repeated beginning on the following day.
