How to Start Mibelas 24 Fe

Instruct the patient to begin taking Mibelas 24 Fe either on the first day of her menstrual period (Day 1 Start) or on the first Sunday after the onset of her menstrual period (Sunday Start).

Day 1 Start

During the first cycle of Mibelas 24 Fe use, instruct the patient to take one white Mibelas 24 Fe tablet daily, beginning on Day one (1) of her menstrual cycle (the first day of menstruation is Day one). She should take one white Mibelas 24 Fe tablet daily for 24 consecutive days, followed by one brown tablet daily on days 25 through 28. Mibelas 24 Fe should be taken in the order directed on the package at the same time each day. Instruct the patient to use a non-hormonal contraceptive as back-up during the first 7 days if she starts taking Mibelas 24 Fe on a day other than the first day of her menstrual cycle. The possibility of ovulation and conception prior to initiation of medication should be considered.

Sunday Start

During the first cycle of Mibelas 24 Fe use, instruct the patient to take one white Mibelas 24 Fe tablet daily, beginning on the first Sunday after the onset of her menstrual period. She should take one white Mibelas 24 Fe tablet daily for 24 consecutive days, followed by one brown tablet daily on days 25 through 28. Mibelas 24 Fe should be taken in the order directed on the package at the same time each day. Mibelas 24 Fe should not be considered effective as a contraceptive until after the first 7 consecutive days of product administration. Instruct the patient to use a non-hormonal contraceptive as back-up during the first 7 days. The possibility of ovulation and conception prior to initiation of medication should be considered.

The patient should begin her next and all subsequent 28-day regimens of Mibelas 24 Fe on the same day of the week that she began her first regimen, following the same schedule. She should begin taking her white Mibelas 24 Fe tablets on the next day after ingestion of the last brown tablet, regardless of whether or not a menstrual period has occurred or is still in progress. Anytime a subsequent cycle of Mibelas 24 Fe is started later than the day following administration of the last brown tablet, the patient should use another method of contraception until she has taken a white Mibelas 24 Fe tablet daily for 7 consecutive days.

For postpartum women who do not breastfeed or after a second trimester abortion, start Mibelas 24 Fe no earlier than 4 weeks postpartum due to the increased risk of thromboembolism. If the patient starts on Mibelas 24 Fe 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 Mibelas 24 Fe for 7 consecutive days.

Mibelas 24 Fe may be initiated immediately after a first-trimester abortion or miscarriage; if the patient starts Mibelas 24 Fe immediately, additional contraceptive measures are not needed.

If she does not have a withdrawal bleed, rule out pregnancy before starting Mibelas 24 Fe.
