Stop Lo Loestrin Fe if there is unexplained loss of vision, proptosis, diplopia, papilledema, or retinal vascular lesions. Evaluate for retinal vein thrombosis immediately. Women who currently have or have had breast cancer should not use Lo Loestrin Fe because breast cancer is a hormonally-sensitive tumor.
There is substantial evidence that COCs do not increase the incidence of breast cancer. Although some past studies have suggested that COCs might increase the incidence of breast cancer, more recent studies have not confirmed such findings. Some studies suggest that COCs are associated with an increase in the risk of cervical cancer or intraepithelial neoplasia.
However, there is controversy about the extent to which these findings may be due to differences in sexual behavior and other factors. Discontinue Lo Loestrin Fe if jaundice develops. Steroid hormones may be poorly metabolized in patients with impaired liver function. 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. Hepatic adenomas are associated with COC use. An estimate of the attributable risk is 3. Rupture of hepatic adenomas may cause death through intra-abdominal hemorrhage.

However, the attributable risk of liver cancers in COC users is less than one case per million users. Oral contraceptive-related cholestasis may occur in women with a history of pregnancy-related cholestasis. For women with well-controlled hypertension, monitor blood pressure and stop Lo Loestrin Fe if blood pressure rises significantly. Women with uncontrolled hypertension or hypertension with vascular disease should not use COCs.
An increase in blood pressure has been reported in women taking COCs, and this increase is more likely in older women with extended duration of use. The incidence of hypertension increases with increasing concentrations of progestin. Studies suggest a small increased relative risk of developing gallbladder disease among COC users. Carefully monitor prediabetic and diabetic women who are taking Lo Loestrin Fe. COCs may decrease glucose tolerance in a dose-related fashion. Consider alternative contraception for women with uncontrolled dyslipidemias.
A small proportion of women will have adverse lipid changes while on COCs. Women with hypertriglyceridemia, or a family history thereof, may be at an increased risk of pancreatitis when using COCs. If a woman taking Lo Loestrin Fe develops new headaches that are recurrent, persistent, or severe, evaluate the cause and discontinue Lo Loestrin Fe if indicated. An increase in frequency or severity of migraine during COC use which may be prodromal of a cerebrovascular event may be a reason for immediate discontinuation of the COC.
Unscheduled breakthrough or intracyclic bleeding and spotting sometimes occur in patients on COCs, especially during the first three months of use.

If bleeding persists or occurs after previously regular cycles, check for causes such as pregnancy or malignancy. If pathology and pregnancy are excluded, bleeding irregularities may resolve over time or with a change to a different COC. A total of 1, women In the clinical trial with Lo Loestrin Fe, the incidence of amenorrhea increased from 32 percent in Cycle 1 to 49 percent by Cycle If scheduled withdrawal bleeding does not occur, consider the possibility of pregnancy. If the patient has not adhered to the prescribed dosing schedule missed one or more active tablets or started taking them on a day later than she should have , consider the possibility of pregnancy at the time of the first missed period and take appropriate diagnostic measures.
If the patient has adhered to the prescribed regimen and misses two consecutive periods, rule out pregnancy. Some women may experience amenorrhea or oligomenorrhea after stopping COCs, especially when such a condition was preexistent. Extensive epidemiologic studies have revealed no increased risk of birth defects in women who have used oral contraceptives prior to pregnancy.
Studies also do not suggest a teratogenic effect, particularly in so far as cardiac anomalies and limb reduction defects are concerned, when oral contraceptives are taken inadvertently during early pregnancy. Lo Loestrin Fe use should be discontinued if pregnancy is confirmed. Administration of oral contraceptives to induce withdrawal bleeding should not be used as a test for pregnancy [see Use in Specific Populations 8. Women with a history of depression should be carefully observed and Lo Loestrin Fe discontinued if depression recurs to a serious degree. The use of COCs may change the results of some laboratory tests, such as coagulation factors, lipids, glucose tolerance, and binding proteins.
Women on thyroid hormone replacement therapy may need increased doses of thyroid hormone because serum concentrations of thyroid binding globulin increase with use of COCs. A woman who is taking COCs should have a yearly visit with her healthcare provider for a blood pressure check and for other indicated healthcare. In women with hereditary angioedema, exogenous estrogens may induce or exacerbate symptoms of angioedema. Chloasma may occasionally occur, especially in women with a history of chloasma gravidarum.
Women with a tendency to chloasma should avoid exposure to the sun or ultraviolet radiation while taking COCs. The following serious adverse reactions with the use of COCs are discussed elsewhere in the labeling:. 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.
A multicenter phase 3 clinical trial evaluated the safety and efficacy of Lo Loestrin Fe for pregnancy prevention. The study was a one year, open-label, single-arm, uncontrolled study. A total of 1, women aged 18 to 45 were enrolled and took at least one dose of Lo Loestrin Fe [see Clinical Studies 14 ]. Adverse Reactions Leading to Study Discontinuation : Serious Adverse Reactions : deep vein thrombosis, ovarian vein thrombosis, cholecystitis.
If a woman on hormonal contraceptives takes a drug or herbal product that induces enzymes, including CYP3A4, that metabolize contraceptive hormones, counsel her to use additional contraception or a different method of contraception. Drugs or herbal products that induce such enzymes may decrease the plasma concentrations of contraceptive hormones, and may decrease the effectiveness of hormonal contraceptives or increase breakthrough bleeding.
Some drugs or herbal products that may decrease the effectiveness of hormonal contraceptives include:. HIV protease inhibitors and non-nucleoside reverse transcriptase inhibitors : Significant changes increase or decrease in the plasma levels of the estrogen and progestin have been noted in some cases of co-administration of HIV 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. Consult the labeling of all concurrently-used drugs to obtain further information about interactions with hormonal contraceptives or the potential for enzyme alterations. Co-administration of atorvastatin and certain COCs containing ethinyl estradiol increase AUC values for ethinyl estradiol by approximately 20 percent.
Ascorbic acid and acetaminophen may increase plasma ethinyl estradiol levels, possibly by inhibition of conjugation. CYP3A4 inhibitors such as itraconazole or ketoconazole may increase plasma hormone levels. COCs containing some synthetic estrogens for example, 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. Consult the labeling of the concurrently-used drug to obtain further information about interactions with COCs or the potential for enzyme alterations. 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. When possible, advise the nursing mother to use other forms of contraception until she has weaned her child. Estrogen-containing OCs 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.

Lo Loestrin Fe norethindrone acetate and ethinyl estradiol tablets, ethinyl estradiol tablets and ferrous fumarate tablets provides an oral contraceptive regimen consisting of 24 blue active tablets and 2 white active tablets that contain the active ingredients specified for each tablet below, followed by 2 non-hormonal placebo tablets:.
Each white tablet also contains the inactive ingredients mannitol, microcrystalline cellulose, sodium starch glycolate, magnesium stearate, povidone, vitamin E and lactose monohydrate. Each brown tablet contains ferrous fumarate, mannitol, povidone, microcrystalline cellulose, sodium starch glycolate, magnesium stearate, sucralose and spearmint flavor. The ferrous fumarate tablets do not serve any therapeutic purpose. Ferrous fumarate tablets are not USP for dissolution and assay. The empirical formula of ethinyl estradiol is C 20 H 24 O 2 and the structural formula is:.
The empirical formula of norethindrone acetate is C 22 H 28 O 3 and the structural formula is:. 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.
Norethindrone acetate is deacetylated to norethindrone after oral administration, and the disposition of norethindrone acetate is indistinguishable from that of orally administered norethindrone. Norethindrone acetate and ethinyl estradiol are absorbed from Lo Loestrin Fe, with maximum plasma concentrations of norethindrone and ethinyl estradiol generally occurring 1 to 2 hours postdose. Both are subject to first-pass metabolism after oral dosing, resulting in an absolute bioavailability of approximately 64 percent for norethindrone and 55 percent for ethinyl estradiol.
Ethinyl estradiol bioavailability from Lo Loestrin Fe tablets containing 10 mcg ethinyl estradiol alone is equivalent to that from an ethinyl estradiol solution. The plasma norethindrone and ethinyl estradiol pharmacokinetic profiles and serum sex hormone binding globulin SHBG concentrations following multiple-dose administration of Lo Loestrin Fe were characterized in 15 healthy female volunteers. The mean plasma concentrations are shown below Figures 1 and 2 , and pharmacokinetic parameters are found in Table 1. Ethinyl estradiol and norethindrone C max values increase by a factor of 1.
Ethinyl estradiol and norethindrone AUC 0—24h values increase by a factor of 1. Norethindrone concentrations more than double by Day 24 due to both accumulation and increased SHBG concentration. Steady state with respect to ethinyl estradiol and norethindrone is reached by Day 5 and Day 13, respectively. Figure 1. Figure 2. Administration of food with a single-dose of a Lo Loestrin Fe combination tablet did not affect the maximum concentration of norethindrone and increased the extent of absorption by 24 percent; it decreased the maximum concentration of ethinyl estradiol by 23 percent and did not affect the extent of absorption.
Administration of food with a single-dose of a Lo Loestrin Fe ethinyl estradiol alone tablet decreased the maximum concentration of ethinyl estradiol by 31 percent and did not affect the extent of absorption. Norethindrone undergoes extensive biotransformation, primarily via reduction, followed by sulfate and glucuronide conjugation. The majority of metabolites in the circulation are sulfates, with glucuronides accounting for most of the urinary metabolites. A small amount of norethindrone acetate is metabolically converted to ethinyl estradiol. Ethinyl estradiol is also extensively metabolized, both by oxidation and by conjugation with sulfate and glucuronide.
Sulfates are the major circulating conjugates of ethinyl estradiol and glucuronides predominate in urine. The primary oxidative metabolite is 2-hydroxy ethinyl estradiol, formed by the CYP3A4 isoform of cytochrome P Part of the first-pass metabolism of ethinyl estradiol is believed to occur in gastrointestinal mucosa.
Lo Loestrin Fe
Ethinyl estradiol may undergo enterohepatic circulation. Norethindrone and ethinyl estradiol are excreted in both urine and feces, primarily as metabolites. Plasma clearance values for norethindrone and ethinyl estradiol are similar approximately 0. The pharmacokinetics of Lo Loestrin Fe in presence of renal or hepatic impairment has not been evaluated [see Use in Specific Populations 8.
In a one year thirteen day cycles multicenter open-label clinical trial, 1, women 18 to 35 years of age, were studied to assess the efficacy of Lo Loestrin Fe, completing the equivalent of 12, day evaluable cycles of exposure. The racial demographic of all enrolled women was: Caucasian The weight range for those women treated was 89 to lbs. Among the women in the trial, 51 percent had not used hormonal contraception immediately prior to enrolling in this study.
Of treated women, The pregnancy rate Pearl Index [PI] in women 18 to 35 years of age was 2. Cycles in which conception did not occur, but which included the use of backup contraception, were not included in the calculation of the PI. The PI includes women who did not take the drug correctly. Do not use Lo Loestrin Fe if you smoke cigarettes and are over 35 years old.
Smoking increases your risk of serious cardiovascular side effects heart and blood vessel problems from birth control pills, including death from heart attack, blood clots or stroke. This risk increases with age and the number of cigarettes you smoke. Birth control pills help to lower the chances of becoming pregnant when taken as directed. Lo Loestrin Fe is a birth control pill. It contains two female hormones, an estrogen called ethinyl estradiol, and a progestin called norethindrone acetate.
