Femexin 28 combination is used to prevent pregnancy in women who can get pregnant with a BMI less than 30 kilograms (kg) per square meter (m2). It works by stopping a woman's egg from fully developing each month. The egg can no longer accept a sperm and fertilization (pregnancy) is prevented.
No contraceptive method is 100 percent effective. Birth control methods such as having surgery to become sterile or not having sex are more effective than birth control patches. Discuss your options for birth control with your doctor.
Femexin 28 will not prevent HIV infection or other sexually transmitted diseases. It will not help as emergency contraception, such as after unprotected sexual contact.
Femexin 28 is available only with your doctor's prescription.
Femexin 28 indications
An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.

Femexin 28 tablets USP is indicated for the prevention of pregnancy in women who elect to use oral contraceptives as a method of contraception.
Oral contraceptives are highly effective for pregnancy prevention. Table 2 lists the typical unintended pregnancy rates for users of combination oral contraceptives and other methods of contraception. The efficacy of these contraceptive methods, except sterilization, the IUD, and implants, depend upon the reliability with which they are used. Correct and consistent use of methods can result in lower failure rates.

Emergency Contraceptive Pills: The FDA has concluded that certain combined oral contraceptives containing ethinyl estradiol and norgestrel or Levonorgestrel (Femexin 28) are safe and effective for use as postcoital emergency contraception. Treatment initiated within 72 hours after unprotected intercourse reduces the risk of pregnancy by at least 75%.9

The percents becoming pregnant in columns (2) and (3) are based on data from populations where contraception is not used and from women who cease using contraception in order to become pregnant. Among such populations, about 89% become pregnant within one year. This estimate was lowered slightly (to 85%) to represent the percent who would become pregnant within one year among women now relying on reversible methods of contraception if they abandoned contraception altogether.

The treatment schedule is one dose within 72 hours after unprotected intercourse and a second dose 12 hours after the first dose. The FDA has declared the following dosage regimens of oral contraceptives to be safe and effective for emergency contraception: for tablets containing 0.05 mg of ethinyl estradiol and 0.50 mg of norgestrel 1 dose is 2 tablets; for tablets containing 0.02 mg of ethinyl estradiol and 0.1 mg of Levonorgestrel (Femexin 28) 1 dose is 5 tablets; for tablets containing 0.03 mg of ethinyl estradiol and 0.15 mg of Levonorgestrel (Femexin 28) 1 dose is 4 tablets.

However, to maintain effective protection against pregnancy, another method of contraception must be used as soon as menstruation resumes, the frequency or duration of breastfeeds is reduced, bottle feeds are introduced, or the baby reaches 6 months of age.
Clinical Studies
The efficacy and safety of Femexin 28 were studied in 2 one-year clinical trials of subjects age 18-49. There were no exclusions for body mass index (BMI), weight, or bleeding history.
The primary efficacy and safety study (313-NA) was a one-year open-label clinical trial that treated 2,134 subjects in North America. Of these subjects 1,213 (56.8%) discontinued prematurely, including 102 (4.8%) discontinued by the Sponsor for early study closure. The mean weight of subjects in this study was 70.38 kg. The efficacy of Femexin 28 was assessed by the number of pregnancies that occurred after the onset of treatment and within 14 days of the last dose. Among subjects 35 years or less, there were 23 pregnancies (4 of these occurred during the interval 1 to 14 days after the last day of pill use) during 12,572 28-day pill packs of use. The resulting total Pearl Index was 2.38 (95% CI: 1.51, 3.57) and the one-year life table pregnancy rate was 2.39 (95% CI: 1.57, 3.62). Pill pack cycles during which subjects used back-up contraception or were not sexually active were not included in these calculations. Among women 35 years or less who took the pills completely as directed, there were 15 pregnancies (method failures) resulting in a Pearl Index of 1.55 (95% CI: 0.87, 2.56) and the one-year life table pregnancy rate was 1.59 (95% CI: 0.95-2.67).
In a second supportive study conducted in Europe (315-EU), 641 subjects were randomized to Femexin 28 (n=323) or the cyclic comparator of 0.1 mg Levonorgestrel (Femexin 28) and 0.02 mg ethinyl estradiol (n=318). The mean weight of subjects in this study was 63.86 kg. The efficacy analysis among women 35 years or less included 2,756 Femexin 28 pill packs and 2,886 cyclic comparator pill packs. There was one pregnancy in the Femexin 28 group that occurred within 14 days following the last dose. There were three pregnancies in the cyclic comparator group.
Inhibition of Menses (Bleeding Profile)
The bleeding profile for subjects in Study 313-NA also was assessed. Women with a history of unscheduled bleeding and/or spotting were not excluded from the study.
In those subjects who provided complete bleeding data, the percentage of patients who were amenorrheic in a given cycle and remained amenorrheic through cycle 13 (cumulative amenorrhea rate) was determined (Figure 2).
Figure 2: Percentage of Subjects with Cumulative Amenorrhea for Each Pill Pack through Pill Pack 13
When prescribing Femexin 28, the convenience of having no scheduled menstrual bleeding should be weighed against the inconvenience of unscheduled bleeding and spotting.

Femexin 28 dosage

The recommended dose for the prevention of pregnancy and the treatment of acne is the same.
To achieve maximum contraceptive effectiveness, Femexin 28 must be administered as directed and at the same time everyday, preferably after the evening meal or at bedtime.
How to Take Femexin 28: Tablets 1-21 contain active ingredients (active tablets).
Tablets must be taken in the order directed on the package every day at about the same time. One tablet is to be taken daily for 21 consecutive days, followed by a 7-day tablet-free interval. Each subsequent pack is started on the day after the tablet-free interval. A withdrawal bleed usually starts on days 2-3 after the last active tablet and may not have finished before the next pack is started.
How to Start Femexin 28: No Hormonal Contraceptive Use Within the Preceding Month: Tablet-taking should start on day 1 of the woman's natural menstrual cycle (ie, the first day of menstrual bleeding). Starting on days 2-7 of the menstrual cycle (eg, Sunday start) is allowed; however, a nonhormonal back-up method of birth control (eg, condoms, spermicide) is recommended during the first 7 days of Femexin 28 use.
Switching from Another Combined
Oral Contraceptive (COC):
Preferably, Femexin 28 use should begin the day after the last active tablet of the previous COC pack has been taken but no later than the day following the usual tablet-free or inactive tablet interval of the previous COC.
Switching from a Progestin-Only Method of Birth Control [Pill, Implant, Intrauterine Device (IUD), injection]: The user may discontinue use of a progestin-only pill on any day and should start use of Femexin 28 the following day. Femexin 28 use should begin on the same day that a progestin-only implant or a progestin-only IUD is removed or on the day that the next progestin-only injection is scheduled.
In each of these situations, the user should be advised to use a nonhormonal back-up method of birth control during the first 7 days of Femexin 28 use.
Following First-Trimester Abortion: Start Femexin 28 immediately. Additional contraceptive measures are not needed.
Postpartum: Since the immediate postpartum period is associated with an increased risk of thromboembolism, Femexin 28 use should begin no sooner than the 28th postpartum day following either delivery in a nonlactating woman or second-trimester abortion. The woman should be advised to use a nonhormonal back-up method of birth control during the first 7 days of Femexin 28 use. However, if intercourse has already occurred, pregnancy must be ruled out before Femexin 28 use is begun; otherwise, the woman must wait until her first menstrual period before beginning Femexin 28 use.
How to Delay a Period: To delay a menstrual period, the user should skip the tablet-free interval and immediately begin a new pack of Femexin 28. The delay may be continued for as long as desired up until all tablets in the new pack are taken. During the delay, the user may experience breakthrough bleeding or spotting. Regular intake of Femexin 28 should be resumed after the usual 7-day tablet-free interval.
Management of Missed Tablets: Contraceptive protection may be reduced if active tablets are missed, particularly if the missing of tablets extends the tablet-free interval.
If one active tablet is missed but is remembered within 12 hours of the usual dose, it should be taken as soon as it is remembered. Subsequent tablets should be taken at the usual time.
If one active tablet is missed and is remembered more than 12 hours after the usual dose or if two or more active tablets are missed, contraceptive protection may be reduced. The last missed tablet should be taken as soon as it is remembered, which may result in the user taking two tablets on the same day. Subsequent tablets should be taken at the usual time. A nonhormonal back-up method of birth control must be used for the next 7 days.
If the user takes the last active tablet before the 7-day interval during which use of a nonhormonal back-up method of birth control is required has ended, the user must begin a new pack immediately; there should be no tablet-free interval between packs. This prevents an extended break in the tablet-taking interval, thereby reducing the risk of escape ovulation. The user is unlikely to have a withdrawal bleed until all tablets in the new pack are taken, although spotting or breakthrough bleeding may be experienced on tablet-taking days. If the user does not have a withdrawal bleed after all tablets in the new pack are taken, pregnancy must be ruled out before tablet-taking is resumed.
Advice in Case of Vomiting and/or Diarrhea: If vomiting or diarrhea occurs within 4 hours after tablet-taking, tablet absorption may be incomplete. The user must take the needed active tablet(s) from a back-up pack.
Always inform the prescriber which medicines or herbal products that the patient is using. Also tell any other doctor or dentist who prescribes another medicine (or the dispensing pharmacist) that the patient uses Femexin 28. The healthcare providers can tell if the patient needs to take additional contraceptive precautions (eg, condoms) and if so, for how long.
Some medicines can make Femexin 28 less effective in preventing pregnancy or can cause unexpected bleeding.
These include medicines used for the treatment of epilepsy (eg, primidone, phenytoin, barbiturates, carbamazepine, oxcarbamazepine) and tuberculosis (eg, rifampicin) or HIV infections (ritonavir) or other infectious disease (eg, griseofulvin, ampicillin, tetracycline) to increase intestinal motility (eg, metoclopramide) and the herbal remedy St. John's wort.
If the patient wants to use herbal products containing St. John 's wort while she is already using Femexin 28, consult the doctor first.
Femexin 28 may decrease efficacy of other medicines eg, medicines containing cyclosporine or the antiepileptic lamotrigine (this could lead to an increased frequency of seizures).
Ask the doctor or pharmacist for advice before taking any medicine.
Laboratory Tests: If the patient needs blood test, inform the doctor or the laboratory staff that she is taking Femexin 28, because oral contraceptives can affect the results of some tests.
