How to Take Minastrin 24 Fe

To achieve maximum contraceptive effectiveness, Minastrin 24 Fe must be taken exactly as directed. Instruct patients to take one tablet by mouth at the same time every day. The tablet should be chewed and swallowed. The patient should drink a full glass (8 ounces) of water immediately after chewing and swallowing the white tablets. Tablets must be taken in the order directed on the blister pack. Tablets should not be skipped or taken at intervals exceeding 24 hours. For patient instructions for missed tablets, [see FDA-approved patient labeling]. Minastrin 24 Fe may be administered without regard to meals [see Clinical Pharmacology (12.3)].

How to Start Minastrin 24 Fe

Instruct the patient to begin taking Minastrin 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 Minastrin 24 Fe use, instruct the patient to take one white Minastrin 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 Minastrin 24 Fe tablet daily for 24 consecutive days, followed by one brown tablet daily on days 25 through 28. Minastrin 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 Minastrin 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 Minastrin 24 Fe use, instruct the patient to take one white Minastrin 24 Fe tablet daily, beginning on the first Sunday after the onset of her menstrual period. She should take one white Minastrin 24 Fe tablet daily for 24 consecutive days, followed by one brown tablet daily on days 25 through 28. Minastrin 24 Fe should be taken in the order directed on the package at the same time each day. Minastrin 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 Minastrin 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 Minastrin 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 Minastrin 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 Minastrin 24 Fe tablet daily for 7 consecutive days.

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

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

Switching from another Hormonal Method of Contraception

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

       Î¿   Another pill

       Î¿   Vaginal ring

       Î¿   Patch

  • Instruct her to take the first white Minastrin 24 Fe tablet on the day she would have taken her next COC pill. She should not continue taking the tablets from her previous birth control pack, and should not skip any days between packs. If she does not have a withdrawal bleed, rule out pregnancy before starting Minastrin 24 Fe.
  • If she previously used a vaginal ring or transdermal patch, she should start using Minastrin 24 Fe on the day she would have resumed the previous product.

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

       Î¿   Progestin-only pill

       Î¿   Implant

       Î¿   Intrauterine system

       Î¿   Injection

  • She may switch any day from a progestin-only pill; instruct her to take the first white Minastrin 24 Fe tablet on the day she would have taken her next progestin-only pill. She should use a non-hormonal method of contraception for 7 consecutive days.
  • If switching from an implant or injection, start the first white Minastrin 24 Fe tablet on the day her next injection would have been due or on the day of removal of her implant.
  • If switching from an IUD, depending on the timing of removal, back-up contraception may be needed.

Advice in Case of Gastrointestinal Disturbances

If the patient vomits or has diarrhea (within 3 to 4 hours after she takes a white Minastrin 24 Fe tablet), she should follow the instructions in the “What to Do if You Miss Tablets” section [see FDA-approved patient labeling].
