Contents:

Indications for use

  • Hormonal contraception.

Mechanism of action

Cyonanz tablets prevent ovulation (pregnancy) and make it harder for sperm to get into the uterus.

Dosage and mode of application

Each package contains 28 tablets:

  • 21 white active tablets each containing 0.5 mg norethindrone and 35 mcg ethinyl estradiol;
  • 7 green non-hormonal tablets that serve as “reminders”.

To achieve maximum contraceptive effectiveness, you must take tablets exactly as directed on the leaflet and at about the same hour each day.

You can take the first tablet on the 1 day of your menstrual period or on the first Sunday after the beginning of your menstrual period.

Take tablets for 28 days in a row. After the last tablet has been taken, start a new course the next day. For the first cycle of a Sunday Start regimen, you should use an additional, non-hormonal method of birth control such as a condom or spermicide during the first 7 days of use.

Pregnancy and breastfeeding

Do not use Cyonanz during pregnancy. If you get pregnant or suspect you may be pregnant, discontinue hormonal contraception and visit your health care provider as soon as possible. After a childbirth or an abortion in the 2 trimester, you should wait 4 weeks prior to using combination oral contraceptives. Consult your doctor about alternative non-hormonal methods of preventing pregnancy.

Do not use Cyonanz if you are breastfeeding. The hormones may decrease the production of breast milk and alter its composition.

What if I miss a pill?

  • If you miss one “active” tablet in Weeks 1, 2, or 3, take it as the day you remember;
  • If you miss two “active” tablets in Week 1 or Week 2, take two tablets the day you remember and two tablets the following day; and then keep taking one tablet per day until you finish the pack. You must use a back-up method of contraception if you have sex in the seven days after missing tablets;
  • If you miss two “active” tablets in the Week 3 or miss three or more “active” tablets in a row during any week, keep taking one tablet per day until Sunday, then discard the remaining the remaining tablets and start a new pack that same day. You must use a back-up method of contraception if you have sex in the seven days after missing tablets;
  • If you miss any of the 7 “reminder” tablets, discard them and keep taking one tablet per day at your usual time until you finish the pack. In this case, you do not need to use a back-up method of contraception for 7 days.
