Hailey 24 Fe (Page 3 of 8)

5.6 Carbohydrate and Lipid Metabolic Effects

Carefully monitor prediabetic and diabetic women who are taking Hailey 24 Fe. COCs may decrease glucose tolerance.

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.

5.7 Headache

If a woman taking Hailey 24 Fe develops new headaches that are recurrent, persistent, or severe, evaluate the cause and discontinue Hailey 24 Fe if indicated. Consider discontinuation of Hailey 24 Fe in the case of increased frequency or severity of migraine during COC use (which may be prodromal of a cerebrovascular event).

5.8 Bleeding Irregularities and Amenorrhea

Unscheduled Bleeding and Spotting

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 contraceptive product.

In a clinical trial of norethindrone acetate and ethinyl estradiol tablets and ferrous fumarate tablets, the frequency and duration of unscheduled bleeding and/or spotting was assessed in 743 women (3,823 28-day cycles). A total of 10 subjects (1.3%) discontinued norethindrone acetate and ethinyl estradiol tablets and ferrous fumarate tablets, at least in part, due to bleeding or spotting. Based on data from the clinical trial, [24 to 38%] of women using norethindrone acetate and ethinyl estradiol tablets and ferrous fumarate tablets experienced unscheduled bleeding per cycle in the six months of the trial. The percent of women who experienced unscheduled bleeding tended to decrease over time.

Amenorrhea and Oligomenorrhea

Women who use norethindrone acetate and ethinyl estradiol tablets and ferrous fumarate tablets may experience absence of withdrawal bleeding, even if they are not pregnant. In the clinical trial with norethindrone acetate and ethinyl estradiol tablets and ferrous fumarate tablets, 31 to 41% of the women using norethindrone acetate and ethinyl estradiol tablets and ferrous fumarate tablets did not have a withdrawal menses in at least one of 6 cycles of use.

Some women may experience amenorrhea or oligomenorrhea after discontinuation of COCs, especially when such a condition was preexistent.

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.

5.9 COC Use Before or During Early Pregnancy

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. Discontinue Hailey 24 Fe use if pregnancy is confirmed.

Administration of COCs to induce withdrawal bleeding should not be used as a test for pregnancy [see Use in Specific Populations (8.1)].

5.10 Depression

Carefully observe women with a history of depression and discontinue Hailey 24 Fe if depression recurs to a serious degree.

5.11 Malignant Neoplasms

Breast Cancer

Hailey 24 Fe is contraindicated in women who currently have or have had breast cancer because breast cancer may be hormonally-sensitive [see Contraindications (4)] .

Epidemiology studies have not found a consistent association between use of combined oral contraceptives (COCs) and breast cancer risk. Studies do not show an association between ever (current or past) use of COCs and risk of breast cancer. However, some studies report a small increase in the risk of breast cancer among current or recent users (<6 months since last use) and current users with longer duration of COC use [see Postmarketing Experience ( 6.2)].

Cervical Cancer

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.

5.12 Effect on Binding Globulins

The estrogen component of COCs may raise the serum concentrations of thyroxine-binding globulin, sex hormone-binding globulin, and cortisol-binding globulin. The dose of replacement thyroid hormone or cortisol therapy may need to be increased.

5.13 Monitoring

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.

5.14 Hereditary Angioedema

In women with hereditary angioedema, exogenous estrogens may induce or exacerbate symptoms of angioedema.

5.15 Chloasma

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 Hailey 24 Fe.

6 ADVERSE REACTIONS

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

6.1 Clinical 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 safety of norethindrone acetate and ethinyl estradiol tablets and ferrous fumarate tablets were evaluated in 743 subjects who participated in an open-label, randomized, active-controlled, multicenter clinical trial of norethindrone acetate and ethinyl estradiol tablets and ferrous fumarate tablets for contraception. This trial examined healthy, non-pregnant volunteers aged 18 to 45 years, who were sexually active and had a body mass index of ≤ 35 kg/m2. Subjects were followed for up to six 28-day cycles providing a total of 3,823 treatment-cycles of exposure.

Common Adverse Reactions (≥ 2% of all subjects): The most common adverse reactions reported by at least 2% of the 743 women using norethindrone acetate and ethinyl estradiol tablets and ferrous fumarate 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%), mood changes (including mood swings (2.2%) and depression (1.1%), bacterial vaginitis (3.1%), acne (2.7%), and weight gain (2.0%).

Adverse Reactions Leading to Study Discontinuation: Among the 743 women using norethindrone acetate and ethinyl estradiol tablets and ferrous fumarate 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 bleeding (0.9%), nausea (0.8%), mood changes (0.8%), menstrual cramps (0.4%), increased blood pressure (0.4%), and irregular bleeding (0.4%).
