WARNING: CIGARETTE SMOKING AND SERIOUS CARDIOVASCULAR EVENTS and CONTRAINDICATED IN WOMEN WITH A BMI ≥ 30 kg/m2
- Cigarette Smoking and Serious Cardiovascular Events
Cigarette smoking increases the risk of serious cardiovascular events from hormonal 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, CHCs, including ZAFEMY, are contraindicated in women who are over 35 years of age and smoke [see Contraindications (4) and Warnings and Precautions (5.1)].
- Contraindicated in Women with a BMI ≥ 30 kg/m2
ZAFEMY is contraindicated in women with a BMI ≥ 30 kg/m2. The risk of VTE may be greater with ZAFEMY in women with a BMI > 30 kg/m2 compared to women with a lower BMI [see Contraindications (4) and Warnings and Precautions (5.1)] .
1 INDICATIONS AND USAGE
ZAFEMY® is indicated for the prevention of pregnancy in women with a body mass index (BMI) < 30 kg/m2 for whom a combined hormonal contraceptive is appropriate.
Limitations of Use:
ZAFEMY may be less effective in preventing pregnancy in women who weigh 198 lbs (90 kg) or more. ZAFEMY is contraindicated for use in women with BMI ≥ 30 kg/m2 [see Contraindications (4), Warnings and Precautions (5.1) and Clinical Studies (14)].
2 DOSAGE AND ADMINISTRATION
To achieve maximum contraceptive effectiveness, ZAFEMY must be used exactly as directed.
Complete instructions to facilitate patient counseling on proper system usage may be found in the FDA-Approved Patient Labeling.
2.1 How to Use ZAFEMY
The ZAFEMY transdermal system uses a 28-day (four-week) cycle. A new patch is applied each week for three weeks (21 total days). Week Four is patch-free. Withdrawal bleeding is expected during this time.
Every new patch should be applied on the same day of the week. This day is known as the “Patch Change Day.” For example, if the first patch is applied on a Monday, all subsequent patches should be applied on a Monday. Only one patch should be worn at a time.
Do not cut, damage or alter the ZAFEMY patch in any way. If the ZAFEMY patch is cut, damaged or altered in size, contraceptive efficacy may be impaired.
On the day after Week Four ends, a new four-week cycle is started by applying a new patch. Under no circumstances should there be more than a seven-day patch-free interval between dosing cycles.
2.2 How to Start Using ZAFEMY
There are multiple options for starting the ZAFEMY patch, and the woman should choose the option that is most appropriate (see Table 1):

Use after Childbirth
Start contraceptive therapy with ZAFEMY in women who elect not to breastfeed no sooner than 4 weeks after childbirth due to increased risk of thromboembolism. If a woman begins using ZAFEMY postpartum, and has not yet had a period, consider the possibility of ovulation and conception occurring prior to use of ZAFEMY, and instruct her to use an additional method of contraception, such as a condom and spermicide or diaphragm and spermicide, for the first seven days [see Warnings and Precautions (5.1) and Pregnancy (8.1)].
Use after Abortion or Miscarriage
After an abortion or miscarriage that occurs in the first trimester, ZAFEMY may be started immediately. An additional method of contraception is not needed if ZAFEMY is started immediately. If use of ZAFEMY is not started within 5 days following a first trimester abortion, the woman should follow the instructions for a woman starting ZAFEMY for the first time. In the meantime she should be advised to use a non-hormonal contraceptive method. Ovulation may occur within 10 days of an abortion or miscarriage.
Start ZAFEMY no earlier than 4 weeks after a second trimester abortion or miscarriage, due to the increased risk of thromboembolic disease [see Contraindications (4) and Warnings and Precautions (5.1)].
