Medically reviewed by Drugs.com. Last updated on Nov 16, 2020.
IMPORTANT: If the Sunday start schedule is selected, the patient should be instructed to use an additional method of protection until after the first week of administration in the initial cycle.
The possibility of ovulation and conception prior to initiation of use should be considered.
The Zovia 1/35 tablet dispensers contain 21 pale pink active tablets arranged in three numbered rows of 7 tablets each, followed by a fourth row of 7 white placebo (inactive) tablets .
Days of the week are embossed on the plastic compact just above the tablets, starting with Sunday on the left.
28-Day Schedule: For a DAY 1 START, count the first day of menstrual flow as Day 1 and the first tablet (pale pink) is then taken on Day 1. For a SUNDAY START when menstrual flow begins on or before Sunday, the first tablet (pale pink) is taken on that day. With either a DAY 1 START or SUNDAY START, 1 tablet (pale pink) is taken each day at the same time for 21 days. Then the white 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.
Spotting, breakthrough bleeding, or nausea. If spotting (bleeding insufficient to require a pad), breakthrough bleeding (heavier bleeding similar to a menstrual flow), or nausea occurs the patient should continue taking her tablets as directed. The incidence of spotting, breakthrough bleeding or nausea is minimal, most frequently occurring in the first cycle. Ordinarily spotting or breakthrough bleeding will stop within a week. Usually the patient will begin to cycle regularly within two or three courses of tablet-taking. In the event of spotting or breakthrough bleeding organic causes should be borne in mind. (See WARNING No. 12.)
Missed menstrual periods. Withdrawal flow will normally occur 2 or 3 days after the last active tablet is taken. Failure of withdrawal bleeding ordinarily does not mean that the patient is pregnant, providing the dosage schedule has been correctly followed. (See WARNING No. 7.)
If the patient has not adhered to the prescribed dosage regimen, the possibility of pregnancy should be considered after the first missed period, and oral contraceptives should be withheld until pregnancy has been ruled out.
If the patient has adhered to the prescribed regimen and misses two consecutive periods, pregnancy should be ruled out before continuing the contraceptive regimen.
The first intermenstrual interval after discontinuing the tablets is usually prolonged; consequently, a patient for whom a 28-day cycle is usual might not begin to menstruate for 35 days or longer. Ovulation in such prolonged cycles will occur correspondingly later in the cycle. Post-treatment cycles after the first one, however, are usually typical for the individual woman prior to taking tablets. (See WARNING No. 12.)
Missed tablets. If a woman misses taking one active tablet, the missed tablet should be taken as soon as it is remembered. In addition, the next tablet should be taken at the usual time. If two consecutive active tablets are missed in week 1 or week 2 of the dispenser, the dosage should be doubled for the next 2 days. The regular schedule should then be resumed, but an additional method of protection must be used as backup for the next 7 days if she has sex during that time or she may become pregnant.
If two consecutive active tablets are missed in week 3 of the dispenser or three consecutive active tablets are missed during any of the first 3 weeks of the dispenser, direct the patient to do one of the following: Day 1 Starters should discard the rest of the dispenser and begin a new dispenser that same day; Sunday Starters should continue to take 1 tablet daily until Sunday, discard the rest of the dispenser and begin a new dispenser that same day. The patient may not have a period this month; however, if she has missed two consecutive periods, pregnancy should be ruled out. An additional method of protection must be used as a backup for the next 7 days after the tablets are missed if she has sex during that time or she may become pregnant.
While there is little likelihood of ovulation if only one active tablet is missed, the possibility of spotting or breakthrough bleeding is increased and should be expected if two or more successive active tablets are missed. However, the possibility of ovulation increases with each successive day that scheduled active tablets are missed.
If one or more placebo tablets of Zovia 1/35 are missed, the schedule should be resumed on the eighth day after the last pale pink colored tablet was taken. Omission of placebo tablets in the 28-tablet courses does not increase the possibility of conception provided that this schedule is followed.
