How to Use ANNOVERA

Instruct patients that ANNOVERA should be used as directed [see How to Start ANNOVERA ( 2.2)] . One ANNOVERA should be placed in the vagina. For maximum contraceptive effectiveness, ANNOVERA is to remain in the vagina continuously for 21 days (3 complete weeks). It is removed for a 1-week dose-free interval, and during this time a withdrawal bleed usually occurs. The removed vaginal system should be cleaned with mild soap and warm water, patted dry with a clean cloth towel or paper towel, and placed in its case during the 1-week dose- free interval. At the end of the dose-free interval, the vaginal system should be cleaned prior to being placed back in the vagina for another 21 continuous days (3 complete weeks). This pattern of ANNOVERA use made up of 3-weeks in and 1-week out is a cycle of use; one ANNOVERA vaginal system will provide contraception for 13 cycles.

With clean hands, the user can choose an insertion position that is comfortable, such as lying down, squatting, or standing. The sides of the vaginal system are pressed together for insertion into the vagina. When properly inserted, the vaginal system should be entirely in the vagina and behind the pelvic bone. The day and time of insertion should be noted so that the vaginal system can be removed 3 weeks later on the same day and at about the same time.

ANNOVERA can be removed by hooking an index finger into the vaginal system inside the vagina and gently pulling the vaginal system.

For patient instructions regarding cleaning the vaginal system, see FDA-approved Patient Information.

How to Start ANNOVERA

IMPORTANT: Consider the possibility of ovulation and conception prior to the first use of ANNOVERA.

No Hormonal Contraceptive Use in the Preceding Cycle and after Copper IUD Removal:

The woman should insert ANNOVERA between days 2 and 5 of her regular menstrual bleeding; no back-up contraception is needed. If menstrual cycles are irregular or if the start is more than 5 days from the last menstrual bleeding, the woman should use an additional barrier method during coitus, such as a male condom or spermicide, for the first 7 days of ANNOVERA use.

Switching from a CHC:

A woman who has been using her CHC method consistently and correctly, and who you are reasonably certain is not already pregnant, may switch from her previous CHC to ANNOVERA on any day of the CHC cycle (Day 1-28), without the need for back-up contraception, but no more than 7 hormone-free days should occur before starting ANNOVERA.

Switching from a Progestin-Only Method [Progestin-only pills (POP), Progestin Injection, Progestin Implant, Progestin Intrauterine System (IUS)]:

If a woman has no contraindications to the use of ethinyl estradiol (EE), she may elect to switch from a progestin-only method to ANNOVERA. If switching from progestin-only pills, she should begin ANNOVERA at the time she would have taken her next POP pill. If switching from an injection, she should begin ANNOVERA at the time of her next scheduled injection. If switching from an implant or an IUS, she should begin ANNOVERA at the time of implant or IUS removal. In all of these cases, the woman should use an additional barrier method during coitus, such as a male condom or spermicide, for the first 7 days of ANNOVERA use.

Use after Abortion or Miscarriage:

If a woman has no contraindications to the use of EE, ANNOVERA may be initiated for contraception within the first 5 days following a complete first trimester abortion or miscarriage without additional back-up contraception. If more than 5 days have elapsed from the first trimester abortion or miscarriage, then follow the instructions for “No Hormonal Contraceptive Use in the Preceding Cycle” and a barrier method should be used from the time of the first trimester abortion or miscarriage to the initiation of ANNOVERA.

ANNOVERA should not be started earlier than 4 weeks after a second trimester abortion or miscarriage due to the increased risk of thromboembolism [see Contraindications ( 4) and Warnings and Precautions ( 5.1)] .

Following Childbirth:

ANNOVERA should not be started sooner than 4 weeks postpartum and only in females who choose not to breastfeed. Prior to 4 weeks postpartum there is an increased risk of thromboembolism [see Contraindications ( 4) and Warnings and Precautions ( 5.1)] .

The initiation of ANNOVERA 4 weeks or more postpartum should be accompanied by an additional method of contraception during coitus, such as male condoms or spermicide, for the first 7 days if the woman has not yet had a period. Consider the possibility of ovulation and conception occurring prior to initiating ANNOVERA.

Females who are breastfeeding should not use ANNOVERA until after weaning.

Deviations from the Recommended Regimen

Contraceptive efficacy of ANNOVERA may be reduced if a woman deviates from the recommended use. ANNOVERA should remain in the vagina for a continuous period of 21 days (3 weeks); then ANNOVERA should be taken out of the vagina for 7 days. In a 28-day cycle, a deviation that involves ANNOVERA being out of the vagina for less than 7 days will not increase pregnancy risk. In a 28-day cycle, a deviation that involves ANNOVERA being out of the vagina for more than 7 days will increase pregnancy risk and back-up contraception is recommended in these instances. Deviations from the recommended regimen may result in a new vaginal system change day [See FDA-approved Patient Information].

Inadvertent Removal or Expulsion

ANNOVERA can be accidently expelled. Accidental expulsion could occur while removing a tampon, during coitus, or with straining during a bowel movement. If the vaginal system is accidentally expelled once during the 21 days of intravaginal use and is replaced within 2 hours, contraceptive efficacy should not be reduced and no back-up contraception is needed. If the vaginal system is accidently expelled, wash it with mild soap and warm water, rinse and pat dry with a clean cloth towel or paper towel, and replace it as soon as possible.

During the 21 days of continuous use, if ANNOVERA is out of the vagina for more than 2 continuous hours or more than 2 cumulative hours (multiple inadvertent removals or expulsions adding up to 2 hours), then back-up contraception, such as male condoms or spermicide, should be used until the vaginal system has been in the vagina for 7 consecutive days. The use of combined hormonal contraceptives (those containing an estrogen) for emergency contraception during use of ANNOVERA is not recommended.

Prolonged Vaginal System Free Interval

If the Vaginal System Free Interval is prolonged, consider the possibility of pregnancy and have the woman use back-up contraception, such as male condoms or spermicide, during coitus until the vaginal system has been in the vagina for 7 consecutive days. The use of combined hormonal contraceptives (those containing an estrogen) for emergency contraception during use of ANNOVERA is not recommended.

Prolonged Use of ANNOVERA

If ANNOVERA is left in the vagina for more than 21 days, it should be removed for 7 days and then reinserted for 21 days to resume a 21/7 schedule.
