Natazia Dosage

How to Take Natazia

To achieve maximum contraceptive effectiveness, Natazia must be taken exactly as directed. Take one tablet by mouth at the same time every day. Tablets must be taken in the order directed on the blister pack. Tablets should not be skipped or intake delayed by more than 12 hours. For patient instructions for missed pills, see FDA-Approved Patient Labeling.

How to Start Natazia

Instruct the patient to begin taking Natazia on Day 1 of her menstrual cycle (that is, the first day of her menstrual bleeding). See FDA-Approved Patient Labeling. Instruct the patient to use a non-hormonal contraceptive as back-up during the first 9 days.

For postpartum women who do not breastfeed or after a second trimester abortion, start Natazia no earlier than 4 weeks postpartum due to the increased risk of thromboembolism. If the patient starts on Natazia postpartum and has not yet had a period, evaluate for possible pregnancy, and instruct her to use an additional method of contraception until she has taken Natazia for 9 consecutive days. The possibility of ovulation and conception prior to initiation of medication should also be considered.

If the patient is switching from a combination hormonal method such as:

•

Another pill

•

Vaginal ring

•

Patch

•

Instruct her to take the first dark yellow pill on the first day of her withdrawal bleed. She should not continue taking the pills from her previous birth control pack. If she does not have a withdrawal bleed, rule out pregnancy before starting Natazia.

•

If she previously used a vaginal ring or transdermal patch, she should start using Natazia on the day the ring or patch is removed.

•

Instruct the patient to use a non-hormonal back-up method such as a condom or spermicide for the first 9 days.

If the patient is switching from a progestin-only method such as a:

•

Progestin-only pill

•

Implant

•

Intrauterine system

•

Injection

•

Instruct her to take the first dark yellow pill on the day she would have taken her next progestin-only pill or on the day of removal of her implant or intrauterine system or on the day when she would have had her next injection.

•

Instruct the patient to use a non-hormonal back-up method such as a condom or spermicide for the first 9 days.

Advice in case of Gastrointestinal Disturbances

In case of severe vomiting or diarrhea, absorption may not be complete and additional contraceptive measures should be taken. If vomiting or diarrhea occurs within 3-4 hours after taking a colored tablet, this can be regarded as a missed tablet.
