🩺 Clinical
Oral contraceptives (birth-control pills) containing ethinyl estradiol (an estrogen) and norethindrone (a progestin) are used to prevent pregnancy. Estrogen and progestin are two female sex hormones. Combinations of estrogen and progestin work mainly by preventing ovulation (the release of eggs from the ovaries). Oral contraceptives are an effective method of birth control, but they do not prevent the spread of human immunodeficiency virus (HIV, the virus that causes acquired immunodeficiency syndrome [AIDS]) and other sexually transmitted diseases.

The patient should drink a full glass (8 ounces) of water immediately after the white tablets are chewed or swallowed whole. 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]. Mibelas 24 Fe may be administered without regard to meals [see CLINICAL PHARMACOLOGY ( 12.3 )].
2.2How 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.…

⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS Vascular risks: Stop Mibelas 24 Fe if a thrombotic event occurs. Stop at least 4 weeks before through 2 weeks after major surgery. Start no earlier than 4 weeks after delivery, in women who are not breastfeeding ( 5.1 ) Liver disease: Discontinue if jaundice occurs ( 5.2 ) High blood pressure: Do not prescribe for women with uncontrolled hypertension or hypertension with vascular disease ( 5.3 ) Carbohydrate and lipid metabolic effects: Monitor prediabetic and diabetic women taking Mibelas 24 Fe.
Consider an alternative contraceptive method for women with uncontrolled dyslipidemia ( 5.5 ) Headache: Evaluate significant change in headaches and discontinue if indicated ( 5.6 ) Uterine bleeding: Evaluate irregular bleeding or amenorrhea ( 5.7 )
5.1Thromboembolic Disorders and Other Vascular Problems Stop Mibelas 24 Fe if an arterial or deep venous thrombotic event (VTE) occurs. Stop Mibelas 24 Fe if there is unexplained loss of vision, proptosis, diplopia, papilledema, or retinal vascular lesions. Evaluate for retinal vein thrombosis immediately.
If feasible, stop Mibelas 24 Fe at least 4 weeks before and through 2 weeks after major surgery or other surgeries known to have an elevated risk of VTE. Start Mibelas 24 Fe no earlier than 4 weeks after delivery, in women who are not breastfeeding. The risk of postpartum VTE decreases after the third postpartum week, whereas the risk of ovulation increases after the third postpartum week.
The use of COCs increases the risk of VTE. However, pregnancy increases the risk of VTE as much or more than the use of COCs. The risk of VTE in women using COCs is 3 to 9 per 10,000 woman-years.
The risk of VTE is highest during the first year of use of a COC. The risk of thromboembolic disease due to oral contraceptives gradually disappears after COC use is discontinued. Use of COCs also increases the risk of arterial thromboses such as strokes and myocardial infarctions, especially in women with other risk factors for these events.
COCs have been shown to increase both the relative and attributable risks of cerebrovascular events (thrombotic and hemorrhagic strokes), although, in general, the risk is greatest in older (greater than 35 years of age), hypertensive women who also smoke. COCs also increase the risk for stroke in women with underlying risk factors. Use COCs with caution in women with cardiovascular disease risk factors.
5.2Liver Disease Impaired Liver Function Do not use Mibelas 24 Fe in women with acute viral hepatitis or severe (decompensated) cirrhosis of the liver [see CONTRAINDICATIONS ( 4) ]. Acute or chronic disturbances of liver function may necessitate the discontinuation of COC use until markers of liver function return to normal and COC causation has been excluded. Discontinue Mibelas 24 Fe if jaundice develops.
Liver Tumors Mibelas 24 Fe is contraindicated in women with benign and malignant liver tumors [see CONTRAINDICATIONS ( 4 )]. Hepatic adenomas are associated with COC use. An estimate of the attributable risk is 3.3 cases per 100,000 COC users.
Rupture of hepatic adenomas may cause death through intra-abdominal hemorrhage. Studies have shown an increased risk of developing hepatocellular carcinoma in long-term (greater than 8 years) COC users. However, the attributable risk of liver cancers in COC users is less than one case per million users.
5.3Risk of Liver Enzyme Elevations with Concomitant Hepatitis C Treatment During clinical trials with the Hepatitis C combination drug regimen that contains ombitasvir/paritaprevir/ritonavir, with or without dasabuvir, ALT elevations greater than 5 times the upper limit of normal (ULN),including some cases greater than 20 times the ULN, were significantly more frequent in women using ethinyl estradiol-containing medications, such as COCs. Discontinue Mibelas 24 Fe prior to starting therapy with the combination drug regimen ombitasvir/paritaprevir/ritonavir, with or without dasabuvir [see Contraindicat…
🤒 Adverse Reactions ▾
6 ADVERSE REACTIONS The most common adverse reactions in clinical trials (greater than or equal to 2%) were: headache, vaginal candidiasis, nausea, menstrual cramps, breast tenderness, bacterial vaginitis, abnormal cervical smear, acne, mood swings, and weight gain. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Lupin Pharmaceuticals, Inc. at 1-800-399-2561 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. The following serious adverse reactions with the use of COCs are discussed elsewhere in the labeling: Serious cardiovascular events and stroke [see BOXED WARNING and WARNINGS AND PRECAUTIONS ( 5.1 )] Vascular events [see WARNINGS AND PRECAUTIONS ( 5.1 )] Liver disease [see WARNINGS AND PRECAUTIONS ( 5.2 )] Adverse reactions commonly reported by COC users are: Irregular uterine bleeding Nausea Breast tenderness Headache
6.1Clinical Trial Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to the rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data presented in Section 6.1 are from a clinical trial conducted with a 24-day regimen of norethindrone acetate 1 mg/ethinyl estradiol 0.020 mg tablets. Mibelas 24 Fe is bioequivalent to these norethindrone acetate/ethinyl estradiol tablets.
Common Adverse Reactions (Greater Than or Equal to 2% of all Treated Subjects) The most common adverse reactions reported by at least 2% of the 743 women using norethindrone acetate/ethinyl estradiol tablets were the following, in order of decreasing incidence: headache (6.3%), vaginal candidiasis (6.1%), nausea (4.6%), menstrual cramps (4.4%), breast tenderness (3.4%), bacterial vaginitis (3.1%), abnormal cervical smear (3.1%), acne (2.7%), mood swings (2.2%), and weight gain (2.0%). Adverse Reactions Leading to Study Discontinuation Among the 743 women using norethindrone acetate/ethinyl estradiol tablets, 46 women (6.2%) withdrew because of an adverse event.
Adverse events occurring in 3 or more subjects leading to discontinuation of treatment were, in decreasing order: abnormal or irregular bleeding (1.3%), nausea (0.8%), menstrual cramps (0.5%), and increased blood pressure (0.4%).
6.2Postmarketing Experience Five studies that compared breast cancer risk between ever-users (current or past use) of COCs and never-users of COCs reported no association between ever use of COCs and breast cancer risk, with effect estimates ranging from 0.90 - 1.12 (Figure 1). Three studies compared breast cancer risk between current or recent COC users (<6 months since last use) and never users of COCs (Figure 1). One of these studies reported no association between breast cancer risk and COC use.
The other two studies found an increased relative risk of 1.19 - 1.33 with current or recent use. Both of these studies found an increased risk of breast cancer with current use of longer duration, with relative risks ranging from 1.03 with less than one year of COC use to approximately 1.4 with more than 8-10 years of COC use. Figure 1 RR = relative risk; OR = odds ratio; HR = hazard ratio. "ever COC" are females with current or past COC use; "never COC use" are females that neverused COCs.
The following adverse reactions have been identified during post approval use of a 24-day regimen of norethindrone acetate 1 mg/ethinyl estradiol 0.020 mg tablets. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or evaluate a causal relationship to drug exposure. Adverse reactions are grouped into System Organ Classes.
Vascular Disorders Thrombosis/embolism (coronary artery, pulmonary, cerebral, deep vein). Hepatobiliary Disorders Cholelithiasis, cholecystitis, hepatic adenoma, hemangioma of liver. Immune System Disorders Hypersensitivity reaction.
Skin and Subcutaneous Disorders Alopecia, rash (general…
🔄 Drug Interactions ▾
7 DRUG INTERACTIONS Drugs or herbal products that induce certain enzymes, including CYP3A4, may decrease the effectiveness of COCs or increase breakthrough bleeding. Counsel patients to use a back-up method or alternative method of contraception when enzyme inducers are used with COCs ( 7.1 ) Consult the labeling of the concurrently-used drug to obtain further information about interactions with COCs or the potential for enzyme alterations. No drug-drug interaction studies were conducted with Mibelas 24 Fe.
7.1Effects of Other Drugs on Combined Oral Contraceptives Substances Diminishing the Efficacy of COCs Drugs or herbal products that induce certain enzymes, including cytochrome P450 3A4 (CYP3A4), may decrease the effectiveness of COCs or increase breakthrough bleeding. Some drugs or herbal products that may decrease the effectiveness of hormonal contraceptives include phenytoin, barbiturates, carbamazepine, bosentan, felbamate, griseofulvin, oxcarbazepine, rifampicin, topiramate and products containing St. John's wort.
Interactions between oral contraceptives and other drugs may lead to breakthrough bleeding and/or contraceptive failure. Counsel women to use an alternative method of contraception or a back-up method when enzyme inducers are used with COCs, and to continue back-up contraception for 28 days after discontinuing the enzyme inducer to ensure contraceptive reliability. Substances Increasing the Plasma Concentrations of COCs Co-administration of atorvastatin and certain COCs containing ethinyl estradiol increase AUC values for ethinyl estradiol by approximately 20%.
Ascorbic acid and acetaminophen may increase plasma ethinyl estradiol concentrations, possibly by inhibition of conjugation. CYP3A4 inhibitors such as itraconazole or ketoconazole may increase plasma hormone concentrations. Human Immunodeficiency Virus (HIV)/ Hepatitis C Virus (HCV) Protease Inhibitors and Non-nucleoside Reverse Transcriptase Inhibitors Significant changes (increase or decrease) in the plasma concentrations of the estrogen and progestin have been noted in some cases of co-administration of HIV/HCV protease inhibitors or of non-nucleoside reverse transcriptase inhibitors.
Antibiotics There have been reports of pregnancy while taking hormonal contraceptives and antibiotics, but clinical pharmacokinetic studies have not shown consistent effects of antibiotics on plasma concentrations of synthetic steroids.
7.2Effects of Combined Oral Contraceptives on Other Drugs COCs containing ethinyl estradiol may inhibit the metabolism of other compounds. COCs have been shown to significantly decrease plasma concentrations of lamotrigine, likely due to induction of lamotrigine glucuronidation. This may reduce seizure control; therefore, dosage adjustments of lamotrigine may be necessary.
Women on thyroid hormone replacement therapy may need increased doses of thyroid hormone because serum concentration of thyroid-binding globulin increases with use of COCs.
7.3Concomitant Use with HCV Combination Therapy – Liver Enzyme Elevation Do not co-administer Mibelas 24 Fe with HCV drug combinations containing ombitasvir/ paritaprevir/ritonavir, with or without dasabuvir, due to potential for ALT elevations [see WARNINGS AND PRECAUTIONS ( 5.3 )] .
7.4Interference with Laboratory Tests The use of contraceptive steroids may influence the results of certain laboratory tests, such as coagulation factors, lipids, glucose tolerance, and binding proteins.
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS Nursing mothers: Not recommended; can decrease milk production ( 8.3 )
8.1Pregnancy There is little or no increased risk of birth defects in women who inadvertently use COCs during early pregnancy. Epidemiologic studies and meta-analyses have not found an increased risk of genital or non-genital birth defects (including cardiac anomalies and limb reduction defects) following exposure to low dose COCs prior to conception or during early pregnancy. The administration of COCs to induce withdrawal bleeding should not be used as a test for pregnancy.
COCs should not be used during pregnancy to treat threatened or habitual abortion.
8.3Nursing Mothers When possible, advise the nursing mother to use other forms of contraception until she has weaned her child. COCs can reduce milk production in breastfeeding mothers. This is less likely to occur once breastfeeding is well-established; however, it can occur at any time in some women. Small amounts of oral contraceptive steroids and/or metabolites are present in breast milk
8.4Pediatric Use Safety and efficacy of Mibelas 24 Fe have been established in women of reproductive age. Efficacy is expected to be the same in postpubertal adolescents under the age of 18 years as for users 18 years and older. Use of this product before menarche is not indicated.
8.5Geriatric Use Mibelas 24 Fe has not been studied in postmenopausal women and is not indicated in this population.
8.6Renal Impairment The pharmacokinetics of Mibelas 24 Fe has not been studied in subjects with renal impairment.
8.7Hepatic Impairment The pharmacokinetics of Mibelas 24 Fe has not been studied in subjects with hepatic impairment. However, steroid hormones may be poorly metabolized in patients with hepatic impairment. Acute or chronic disturbances of liver function may necessitate the discontinuation of COC use until markers of liver function return to normal and COC causation has been excluded [see CONTRAINDICATIONS ( 4 ) and WARNINGS AND PRECAUTIONS ( 5.2 )].
8.8Body Mass Index The safety and efficacy of Mibelas 24 Fe in women with a body mass index (BMI) greater than 35 kg/m 2 has not been evaluated [see CLINICAL STUDIES ( 14 )].

🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action COCs lower the risk of becoming pregnant primarily by suppressing ovulation. Other possible mechanisms may include cervical mucus changes that inhibit sperm penetration and endometrial changes that reduce the likelihood of implantation.
12.2Pharmacodynamics No specific pharmacodynamic studies were conducted with Mibelas 24 Fe.
12.3Pharmacokinetics Absorption In a single-dose, two-way, crossover clinical study conducted in 35 healthy, non-smoking premenopausal women under fasting condition, Mibelas 24 Fe tablet chewed and swallowed was bioequivalent to norethindrone acetate 1 mg/ethinyl estradiol 0.020 mg tablet (24-day regimen tablets) swallowed whole based on the exposure (AUC) and peak concentration (C max ) of norethindrone and ethinyl estradiol. Norethindrone acetate appears to be completely and rapidly deacetylated to norethindrone after oral administration, because the disposition of norethindrone acetate is indistinguishable from that of orally administered norethindrone.
Norethindrone acetate and ethinyl estradiol are absorbed from Mibelas 24 Fe tablets (chewed and swallowed), with maximum plasma concentrations of norethindrone and ethinyl estradiol occurring at 1.0 hr (range: 0.7 to 2.5 hrs) and 1.3 hr (range: 1 to 2.5 hrs) post-dose, respectively. Both are subject to first-pass metabolism after oral dosing, resulting in an absolute bioavailability of approximately 64% for norethindrone and 43% for ethinyl estradiol. The plasma norethindrone and ethinyl estradiol pharmacokinetics following single-dose administrations of Mibelas 24 Fe tablets (chewed and swallowed) in 35 healthy female subjects are provided in Figures 1 and 2, and Table 1.
Following multiple-dose administration of norethindrone acetate/ethinyl estradiol tablets (swallowed whole) in 17 healthy female subjects, mean maximum concentrations of norethindrone and ethinyl estradiol were increased by 95% and 27%, respectively, as compared to single-dose administration. Mean norethindrone and ethinyl estradiol exposures (AUC values) were increased by 164% and 51% respectively, as compared to single-dose administration of norethindrone acetate/ethinyl estradiol tablets. Steady-state with respect to norethindrone was reached by Day 17 and steady-state with respect to ethinyl estradiol was reached by Day 13.
Mean SHBG concentrations were increased by 150% from baseline (57.5 nmol/L) to 144 nmol/L at steady-state. Figure 2.
