Brand: Zenchent Fe, Zenchent, Estrostep Fe, Loestrin Fe
Generic: Ethinyl Estradiol and Norethindrone
Zenchent Fe is a hormonal contraceptive drug, used to promote birth control or prevent pregnancy. It is a hormone combination of Ethinyl estradiol and norethindrone on an active pill with a minimal amount of ferrous fumarate or iron on its inactive pill.
It functions by inhibiting ovulation; making the cervical mucus thick to prevent the sperm from meeting the egg cell for fertilization; and changes the uterine lining to prevent attachment of the fertilized egg. All of these phenomena prevent pregnancy from occurring.
The inactive pills of Zenchent Fe are not intended to treat iron deficiency but they serve as reminder pills during the 4th week while you are having your menstruation. Once these reminder pills are consumed, you are required to start a new pack of this contraceptive medication.
Read your medication guide and follow your doctor’s prescription at all times:
- Take Zenchent Fe by mouth/orally, once a day with 24 hours interval mostly after dinner to prevent nausea and stomach upset or any time of the day which you can easily remember. The first pill must be taken on the first day of your menstruation and continue taking the pills per doctor’s recommendation.
- The dosage depends on your medical condition or treatment response. Do not adjust your dose without your doctor’s recommendation.
- Continue taking this medication on a regular schedule (same time of the day). Do not stop taking this medication abruptly without consulting your doctor.
- Refill your pills before you run out of stock to avoid missed doses.
- Consult your doctor regularly while on Zenchent Fe, particularly if you don’t have a menstrual period for 2 consecutive months as this may indicate pregnancy.
Inform your doctor immediately if your condition aggravates or does not improve.
If you missed one dose (1 pill), take 2 pills on the same day as soon as possible and then resume regular dosage (1 pill per day) on the succeeding days.
If you missed two doses (2 pills) in 2 consecutive days on the first or second week, take 2 pills each day for 2 days and then resume regular dosage on the succeeding days.
If you missed 2 doses on the third week or 3 doses in either of the first, second or third week in consecutive days, discard your present pack of pills and start a new pack.
Use a back-up birth control method if you miss a dose (i.e. condom, spermicide).
