Minastrin 24 Fe is a combination birth control pills containing female hormones (ethinyl estradiol and norethindrone) and the mineral iron (ferrous fumarate) used to prevent pregnancy.
Indications for use
Minastrin 24 Fe is used for oral long-term contraception.
In addition, Minastrin 24 Fe chewable pills are able to make your periods regular, reduce blood loss and painful menstruation (dysmenorrhea), and reduce cysts. These birth control pills will not protect you or your partner from diseases that are transmitted sexually.
Mechanism of action
This drug is a combination of female hormones (ethinyl estradiol and norethindrone) that prevent ovulation (release of the ovum from the ovary). This drug also causes changes in the cervical mucus and mucous membrane of the uterus, which makes it more difficult for the sperm to reach the uterus and more difficult for a fertilized egg to attach to the uterus.
Dosage and mode of application
Minastrin 24 Fe pills are available in a blister containing 28 tablets (24 active tablets containing 1 mg of norethindrone acetate and 20 mcg of ethinyl estradiol and 4 non-hormonal pills containing 75 mg of ferrous fumarate). These 4 inert tablets do not have any medication and are used as reminders.
