Chateal EQ (Page 3 of 6)

5. Carcinogenesis

See WARNINGS (11).

6. Pregnancy

Risk Summary

Chateal EQ is contraindicated in pregnancy because there is no reason to use COCs in pregnancy. Discontinue Chateal EQ if pregnancy occurs. Epidemiologic studies and meta-analyses have not found an increased risk of genital or nongenital birth defects (including cardiac anomalies and limb-reduction defects) following exposure to COCs before conception or during early pregnancy. Animal studies to evaluate embryo/fetal toxicity were not conducted.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4 percent and 15 to 20 percent, respectively.

7. Lactation

Risk Summary

Contraceptive hormones and/or metabolites are present in human milk. COCs can reduce milk production in breast-feeding females. This reduction can occur at any time but is less likely to occur once breast-feeding is well-established. When possible, advise the nursing female to use other methods of contraception until she discontinues breast-feeding. (see DOSAGE AND ADMINISTRATION). The developmental and health benefits of breast-feeding should be considered along with the mother’s clinical need for Chateal EQ and any potential adverse effects on the breast-fed child from Chateal EQ or from the underlying maternal condition.

8. Pediatric Use

Safety and efficacy of Chateal EQ have been established in females of reproductive potential. Use of Chateal EQ before menarche is not indicated.

9. Geriatric Use

Chateal EQ has not been studied in postmenopausal women and is not indicated in this population.

10. PATIENT COUNSELING INFORMATION

  • Counsel patients that cigarette smoking increases the risk of serious cardiovascular events from COC use, and that women who are over 35 years old and smoke should not use COCs.
  • Counsel patients that this product does not protect against HIV-infection (AIDS) and other sexually transmitted infections.
  • Counsel patients to take one tablet daily by mouth at the same time every day. Instruct patients what to do in the event pills are missed.
  • Counsel patients to use a back-up or alternative method of contraception when enzyme inducers are used with COCs.
  • Counsel patients who are breastfeeding or who desire to breastfeed that COCs may reduce breast milk production. This is less likely to occur if breastfeeding is well established.
  • Counsel any patient who starts Chateal EQ postpartum, and who has not yet had a period, to use an additional method of contraception until she has taken an orange tablet for 7 consecutive days.
  • Counsel patients that amenorrhea may occur. Pregnancy should be considered in the event of amenorrhea, and should be ruled out if amenorrhea is associated with symptoms of pregnancy, such as morning sickness or unusual breast tenderness.

ADVERSE REACTIONS

The following serious adverse reactions with the use of COCs are discussed elsewhere in the labeling:

OVERDOSAGE

DOSAGE AND ADMINISTRATION

1. How to Start and Take Chateal EQ

Chateal EQ is dispensed in a blister pack containing 28 tablets (see HOW SUPPLIED). Chateal EQ may be started using either a Day 1 start or a Sunday start (see Table 3). For the first cycle of a Sunday start regimen, an additional method of contraception should be used until after the first 7 consecutive days of administration.
Table 3: Instructions for Administration of Chateal EQ

Starting Chateal EQ in females with no current use of hormonal contraception Day 1 start
  • Take first tablet without regard to meals on the first day of menses
  • Take subsequent tablets once daily at the same time each day
  • Begin each subsequent pack on the same day of the week as the first cycle pack (i.e., on the day after taking the last tablet)
Sunday start
  • Take first tablet without regard to meals on the first Sunday after the onset of menstrual period
  • Take subsequent tablets once daily at the same time each day
  • Use additional nonhormonal contraception for the first seven days of product use
  • Begin each subsequent pack on the same day of the week as the first cycle pack (i.e., on the day after taking the last tablet)
Switching from another contraceptive method
  • A COC
  • Transdermal patch
  • Vaginal ring
  • Injection
  • Intrauterine contraceptive
  • Implant
Start Chateal EQ:
  • On the day when the new pack of the previous COC would have been started
  • On the day when next application would have been scheduled
  • On the day when next insertion would have been scheduled
  • On the day when next injection would have been scheduled
  • On the day of removal

Starting Chateal EQ after Abortion or Miscarriage

First-trimester

  • After a first-trimester abortion or miscarriage, Chateal EQ may be started immediately. An additional method of contraception is not needed if Chateal EQ is started immediately.
  • If Chateal EQ is not started within 5 days after termination of the pregnancy, the patient should use additional non-hormonal contraception (such as condoms or spermicide) for the first seven days of her first cycle of Chateal EQ.

Second-trimester

  • Do not start until 4 weeks after a second-trimester abortion or miscarriage, due to the increased risk of thromboembolic disease. Start Chateal EQ following the instructions in Table 3 for Day 1 or Sunday start. Use additional non-hormonal contraception (such as condoms or spermicide) for the first seven days of the patient’s first cycle of Chateal EQ (see CONTRAINDICATIONS, WARNINGS (1), PRECAUTIONS (10) and FDA-APPROVED PATIENT LABELING).

Starting Chateal EQ after Childbirth

  • Do not start until 4 weeks after delivery, due to the increased risk of thromboembolic disease. Start contraceptive therapy with Chateal EQ following the instructions in Table 3 for women not currently using hormonal contraception.
  • Chateal EQ is not recommended for use in lactating women (see PRECAUTIONS (7) and FDA-APPROVED PATIENT LABELING).
  • If the woman has not yet had a period postpartum, consider the possibility of ovulation and conception occurring prior to use of Chateal EQ (see CONTRAINDICATIONS, WARNINGS (9), PRECAUTIONS (6) and FDA-APPROVED PATIENT LABELING).

2. Dosing Chateal EQ

Instruct patients to take one tablet by mouth at the same time every day. To achieve maximum contraceptive effectiveness, patients must take Chateal EQ as directed, in the order directed on the blister pack. The failure rate may increase when pills are missed or taken incorrectly.
3. Missed doses

Instruct patients about the handling of missed doses (e.g., to take single missed pills as soon as possible) and to follow the dosing instructions provided in the FDA-approved patient labeling.

Table 4: Instructions for Missed Chateal EQ

  • If one active tablet is missed in Weeks 1, 2, or 3
Take the tablet as soon as possible. Continue taking one tablet a day until the pack is finished.
  • If two active tablets are missed in Week 1 or Week 2
Take the two missed tablets as soon as possible and the next two active tablets the next day. Continue taking one tablet a day until the pack is finished. Additional nonhormonal contraception (such as condoms or spermicide) should be used as back-up if the patient has sex within 7 days after missing tablets.
  • If two active tablets are missed in the third week or three or more active tablets are missed in a row in Weeks 1, 2, or 3
Day 1 start: Throw out the rest of the pack and start a new pack that same day.Sunday start: Continue taking one tablet a day until Sunday, then throw out the rest of the pack and start a new pack that same day.Additional nonhormonal contraception (such as condoms or spermicide) should be used as back-up if the patient has sex within 7 days after missing tablets.

4. Advice in Case of Gastrointestinal Disturbances

If vomiting occurs within 3 to 4 hours after taking Chateal EQ, the patient should proceed as if she missed a tablet. In case of prolonged vomiting or diarrhea, absorption may not be complete and additional contraceptive measures should be taken.
