WARNINGS
Ethinyl estradiol; levonorgestrel are combination oral
contraceptive (COC) pills. The following are the warnings
given for daily cyclical combination oral contraceptive
pill use (1 pill each day for 21 days of a 28-day cycle).
It is not known whether these warnings also apply to the
ECP regimen of four oral contraceptive pills taken within
a 12-hour period.
| Cigarette smoking increases
the risk of serious cardiovascular side effects from
COC use. This risk increases with age and heavy smoking
(15 or more cigarettes per day) and is quite
marked in women over 35 years of age. Women who use
COCs should be strongly advised not to smoke. |
Cardiovascular Disease (CVD)
COC use is associated with a small increase in the incidence
of cardiovascular disease (CVD), primarily because of
an increased risk of thrombosis rather than through an
atherogenic mechanism. The degree of risk appears to be
related primarily to the estrogen dosage. This increased
risk is limited to the period during COC use and disappears
upon cessation of use. Because the incidence of CVD is
low during the reproductive years, the absolute risk attributable
to COC use is quite small.
Deep Vein Thrombosis, Pulmonary Embolism
Use of COCs is associated with a low absolute risk of
venous thromembolism which is nonetheless 3- to 6-fold
higher than that among non-users. Smoking does not appear
to be a risk factor.
The presence of factor V Leiden mutation and other hereditary
coagulation disorders increases the risk of thromboembolic
disease.
COC use is contraindicated for women who have deep vein
thrombosis or pulmonary embolism and for those who have
a history of these conditions.
Women who are immobilized for prolonged periods because
of major surgery (or illness or injury) should not use
COCs. For women undergoing major surgery without prolonged
immobilization, the advantages of COC use generally outweigh
the risk.
COC use should preferably not begin until two to three
weeks postpartum, because of the risk of thrombosis.
Cerebrovascular Disease
In women who do not smoke and do not have hypertension,
the risk of ischemic stroke in users of COCs is increased
about 1.5 fold compared with non-users. The likelihood
of hemorrhagic stroke is not increased among users of
low-dose combined COCs who are under 35 years old and
do not smoke or have hypertension. Women who have a history
of stroke should not use COCs.
Ischemic Heart Disease
The likelihood of myocardial infarction is not increased
among young women who use COCs and do not smoke or have
hypertension or diabetes. Smokers older than 35 should
not take COCs. Women who currently have ischemic heart
disease, or who have a history of this disease, should
not use COCs.
Valvular Heart Disease
COC use is contraindicated for women whose valvular heart
disease is complicated by such factors as pulmonary hypertension,
atrial fibrillation, or history of sub-acute bacterial
encarditis. COC use may be acceptable for women with uncomplicated
valvular heart disease.
Elevated Blood Pressure
For women with an elevation in blood pressure (160+/100+mmHg),
COC use would present an unacceptable health risk, and
COCs should not be used. Similarly, hypertensive women
with vascular disease should not use COCs.
Ocular Lesions
There have been clinical case reports of retinal thrombosis
associated with the use of oral contraceptives. Oral contraceptives
should be discontinued if there is unexplained partial
or complete loss of vision; onset of proptosis or diplopia;
papilledema; or retinal vascular lesions.
Carbohydrate Metabolism
For women with diabetes (both insulin-dependent and non-insulin
dependent), who do not have vascular involvement, the
advantages of COC use generally outweigh the risks, particularly
the risks associated with pregnancy. The major concerns
are vascular disease and added risk of thrombosis, although
COC use by diabetic women appears to have only minimal
effects on lipid metabolism and hemostasis. For diabetic
women with nephropathy, retinopathy, neuropathy, or other
vascular involvement, the risk-benefit ratio depends on
the severity of the condition.
Headaches
For women with severe, recurrent headaches, including
migraine headaches, the appropriateness of using COCs
depends on the presence or absence of focal neurologic
symptoms. These symptoms may reflect an increased risk
of stroke and COC use is contraindicated in patients in
whom they are present. The onset or exacerbation of migraines
or the development of severe headache with focal neurological
symptoms, which are recurrent or persistent, requires
discontinuation of COC use and evaluation of the cause.
Unexplained Vaginal Bleeding
Women who have unexplained vaginal bleeding, suggestive
of an underlying pathological condition or pregnancy,
should be evaluated prior to initiation of COC use in
order to avoid confusion of the pathological bleeding
with COC side effects.
Liver Disease
Because steroid hormones are metabolized by the liver,
women taking COCs may experience adverse hepatobiliary
effects. Although case-control studies have indicated
that the risk of both benign and malignant liver tumors
may be slightly increased by COC use, the incidence potentially
attributable to COCs in the United States is minimal because
the disease is very rare.
Women who currently have active liver disease
should not use COCs.
Ectopic Pregnancy
Ectopic as well as intrauterine pregnancy may occur in
contraceptive failures.
PRECAUTIONS
Sexually Transmitted Diseases: Women should be informed
that this product does not protect against infection with
HIV (the virus that causes AIDS) and other sexually transmitted
diseases (STDs). If a woman is at high risk for STDs she
should be encouraged to reduce risky behavior and to use
condoms or other barrier methods (in addition to COCs).
Pregnancy: Extensive research has found
no significant effects on fetal development associated
with long-term use of contraceptive doses of oral steroids
before pregnancy or taken inadvertently during early pregnancy.
Nursing Mothers: Oral contraceptive
steroids have been reported in the milk of breastfeeding
mothers with no apparent clinical significance; long-term
follow-up of breastfeeding mothers with no apparent clinical
significance; long-term follow-up of children whose mothers
used COCs while breastfeeding has shown no deleterious
effects.
Pediatric Use: The safety and efficacy
of COCs have been established in women of reproductive
age. Safety and efficacy are expected to be the same for
postpubertal adolescents under 16 and users 16 and older.
Use of this product before menarche is not indicated.
Repeated Use of Emergency Contraceptive Pills:
The effect of repeated use of ECPs (more than once in
a menstrual cycle or in multiple cycles) is unknown.
