PRECAUTIONS
Thromboembolic Disorders And Other Vascular Problems
Stop Yasmin if an arterial or venous thrombotic (VTE)
event occurs.
Based on presently available information on Yasmin,
DRSP-containing COCs may be associated with a higher risk of venous
thromboembolism (VTE) than COCs containing the progestin levonorgestrel or some
other progestins. Epidemiologic studies that compared the risk of VTE reported
that the risk ranged from no increase to a three-fold increase. Before
initiating use of Yasmin in a new COC user or a woman who is switching from a
contraceptive that does not contain DRSP, consider the risks and benefits of a
DRSP-containing COC in light of her risk of a VTE. Known risk factors for VTE
include smoking, obesity, and family history of VTE, in addition to other
factors that contraindicate use of COCs [see CONTRAINDICATIONS].
A number of studies have compared the risk of VTE for
users of Yasmin to the risk for users of other COCs, including COCs containing
levonorgestrel. Those that were required or sponsored by regulatory agencies
are summarized in Table 1.

In addition to these
“regulatory studies,” other studies of various designs have been conducted.
Overall, there are two prospective cohort studies (see Table 1): the US
post-approval safety study Ingenix [Seeger 2007], the European post-approval
safety study EURAS (European Active Surveillance Study) [Dinger 2007]. An
extension of the EURAS study, the Long-Term Active Surveillance Study (LASS),
did not enroll additional subjects, but continued to assess VTE risk. There are
three retrospective cohort studies: one study in the US funded by the FDA (see
Table 1), and two from Denmark [Lidegaard 2009, Lidegaard 2011]. There are two
case-control studies: the Dutch MEGA study analysis [van Hylckama Vlieg 2009] and
the German case-control study [Dinger 2010]. There are two nested case-control
studies that evaluated the risk of non-fatal idiopathic VTE: the PharMetrics
study [Jick 2011] and the GPRD study [Parkin 2011]. The results of all of these
studies are presented in Figure 1.

Although the absolute VTE rates
are increased for users of hormonal contraceptives compared to non-users, the
rates during pregnancy are even greater, especially during the post-partum
period (see Figure 2). The risk of VTE in women using COCs has been estimated
to be 3 to 9 per 10,000 woman-years. The risk of VTE is highest during the
first year of use. Data from a large, prospective cohort safety study of
various COCs suggest that this increased risk, as compared to that in non-COC
users, is greatest during the first 6 months of COC use. Data from this safety
study indicate that the greatest risk of VTE is present after initially
starting a COC or restarting (following a 4 week or greater pill-free interval)
the same or a different COC.
The risk of thromboembolic
disease due to oral contraceptives gradually disappears after COC use is
discontinued.
Figure 2 shows the risk of
developing a VTE for women who are not pregnant and do not use oral
contraceptives, for women who use oral contraceptives, for pregnant women, and
for women in the postpartum period. To put the risk of developing a VTE into
perspective: If 10,000 women who are not pregnant and do not use oral
contraceptives are followed for one year, between 1 and 5 of these women will
develop a VTE.
Figure 2 : Likelihood of Developing a VTE
If feasible, stop Yasmin at
least 4 weeks before and through 2 weeks after major surgery or other surgeries
known to have an elevated risk of thromboembolism.
Start Yasmin no earlier than 4
weeks after delivery, in women who are not breastfeeding. The risk of
postpartum thromboembolism decreases after the third postpartum week, whereas
the risk of ovulation increases after the third postpartum week.
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 among older ( > 35 years of age), hypertensive women who also smoke.
COCs also increase the risk for stroke in women with other underlying risk
factors.
Oral contraceptives must be
used with caution in women with cardiovascular disease risk factors.
Stop Yasmin if there is
unexplained loss of vision, proptosis, diplopia, papilledema, or retinal
vascular lesions. Evaluate for retinal vein thrombosis immediately. [See ADVERSE
REACTIONS]
Hyperkalemia
Yasmin contains 3 mg of the
progestin DRSP, which has anti-mineralocorticoid activity, including the
potential for hyperkalemia in high-risk patients, comparable to a 25 mg dose of
spironolactone. Yasmin is contraindicated in patients with conditions that
predispose to hyperkalemia (that is, renal impairment, hepatic impairment, and
adrenal insufficiency). Women receiving daily, long-term treatment for chronic
conditions or diseases with medications that may increase serum potassium
concentration should have their serum potassium concentration checked during
the first treatment cycle. Medications that may increase serum potassium
concentration include ACE inhibitors, angiotensin–II receptor antagonists,
potassium-sparing diuretics, potassium supplementation, heparin, aldosterone
antagonists, and NSAIDs. Consider monitoring serum potassium concentration in
high-risk patients who take a strong CYP3A4 inhibitor long-term and
concomitantly. Strong CYP3A4 inhibitors include azole antifungals (e.g.
ketoconazole, itraconazole, voriconazole), HIV/HCV protease inhibitors (e.g.,
indinavir, boceprevir), and clarithromycin [see CLINICAL PHARMACOLOGY].
Carcinoma Of The Breasts And Reproductive
Organs
Women who currently have or
have had breast cancer should not use Yasmin because breast cancer is a
hormonallysensitive 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.
Liver Disease
Discontinue Yasmin 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 3.3 cases/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 ( > 8 years) COC users. 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. Women with a history of
COC-related cholestasis may have the condition recur with subsequent COC use.
High Blood Pressure
For women with well-controlled hypertension, monitor
blood pressure and stop Yasmin 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 and with extended
duration of use. The incidence of hypertension increases with increasing
concentration of progestin.
Gallbladder Disease
Studies suggest a small increased relative risk of
developing gallbladder disease among COC users.
Carbohydrate And Lipid Metabolic Effects
Carefully monitor prediabetic and diabetic women who are
taking Yasmin. COCs may decrease glucose tolerance in a dose-related fashion.
Consider alternative contraception for women with
uncontrolled dyslipidemia. 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.
Headache
If a woman taking Yasmin develops new headaches that are
recurrent, persistent, or severe, evaluate the cause and discontinue Yasmin 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.
Bleeding Irregularities
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.
Data from ten contraceptive efficacy clinical trials
(N=2,467) show that the percent of women who took Yasmin and experienced
unscheduled bleeding decreased over time from 12% at cycle 2 to 6% (cycle 13).
A total of 24 subjects out of 2,837 in the Yasmin trials ( < 1%) discontinued
due to bleeding complaints. These are described as metrorrhagia, vaginal
hemorrhage, menorrhagia, abnormal withdrawal bleeding, and menometrorrhagia.
The average duration of scheduled bleeding episodes in
the majority of subjects (86%-88%) was 4-7 days. Women who use Yasmin may
experience absence of withdrawal bleeding, even if they are not pregnant. Based
on subject diaries from contraceptive efficacy trials, during cycles 2–13,
1-11% of women per cycle experienced no withdrawal bleeding. Some women may
encounter post-pill amenorrhea or oligomenorrhea, especially when such a
condition was pre-existent.
If 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.
COC Use Before Or During Early Pregnancy
Extensive epidemiological 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 when COCs are taken
inadvertently during early pregnancy, particularly in so far as cardiac
anomalies and limb-reduction defects are concerned.
The administration of oral contraceptives to induce
withdrawal bleeding should not be used as a test for pregnancy [see Use in
Specific Populations].
Depression
Women with a history of depression should be carefully
observed and Yasmin discontinued if depression recurs to a serious degree.
Interference With Laboratory Tests
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 [see DRUG INTERACTIONS].
DRSP causes an increase in plasma renin activity and
plasma aldosterone induced by its mild anti-mineralocorticoid activity.
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.
Other Conditions
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.
Patient Counseling Information
See “FDA-approved patient labeling (PATIENT INFORMATION).”
- Counsel patients that cigarette smoking increases the
risk of serious cardiovascular events from COC use, and that women who are over
35 years old and smoke should not use COCs.
- Counsel patients that the increased risk of VTE compared
to non-users of COCs is greatest after initially starting a COC or restarting
(following a 4-week or greater pill-free interval) the same or a different COC.
- Counsel patients about the information regarding the risk
of VTE with DRSP-containing COCs compared to COCs that contain levonorgestrel
or some other progestins.
- Counsel patients that Yasmin does not protect against HIV
infection (AIDS) and other sexually transmitted diseases.
- Counsel patients on WARNINGS AND PRECAUTIONS associated
with COCs.
- Counsel patients that Yasmin contains DRSP. Drospirenone
may increase potassium. Patients should be advised to inform their healthcare
provider if they have kidney, liver or adrenal disease because the use of
Yasmin in the presence of these conditions could cause serious heart and health
problems. They should also inform their healthcare provider if they are
currently on daily, long-term treatment (NSAIDs, potassium-sparing diuretics,
potassium supplementation, ACE inhibitors, angiotensin-II receptor antagonists,
heparin or aldosterone antagonists) for a chronic condition or taking strong
CYP3A4 inhibitors.
- Inform patients that Yasmin is not indicated during
pregnancy. If pregnancy occurs during treatment with Yasmin, instruct the
patient to stop further intake.
- Counsel patients to take one tablet daily by mouth at the
same time every day. Instruct patients what to do in the event pills are
missed. See “What to Do if You Miss Pills” section in FDA-Approved
Patient Labeling.
- Counsel patients to use a back-up or alternative method
of contraception when enzyme inducers are used with COCs.
- Counsel patients who are breastfeeding or who desire to
breastfeed that COCs may reduce breast milk production. This is less likely to
occur if breastfeeding is well established.
- Counsel any patient who starts COCs postpartum, and who
has not yet had a period, to use an additional method of contraception until
she has taken a yellow tablet for 7 consecutive days.
- Counsel patients that amenorrhea may occur. Rule out
pregnancy in the event of amenorrhea in two or more consecutive cycles.
Nonclinical Toxicology
Carcinogenesis, Mutagenesis, Impairment Of Fertility
In a 24 month oral carcinogenicity study in mice dosed
with 10 mg/kg/day DRSP alone or 1 + 0.01, 3 + 0.03 and 10 + 0.1 mg/kg/day of
DRSP and EE, 0.1 to 2 times the exposure (AUC of DRSP) of women taking a
contraceptive dose, there was an increase in carcinomas of the harderian gland
in the group that received the high dose of DRSP alone. In a similar study in
rats given 10 mg/kg/day DRSP alone or 0.3 + 0.003, 3 + 0.03 and 10 + 0.1
mg/kg/day DRSP and EE, 0.8 to 10 times the exposure of women taking a
contraceptive dose, there was an increased incidence of benign and total
(benign and malignant) adrenal gland pheochromocytomas in the group receiving
the high dose of DRSP. Mutagenesis studies for DRSP were conducted in vivo and in
vitro and no evidence of mutagenic activity was observed.
Use In Specific Populations
Pregnancy
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.
Women who do not breastfeed may start COCs no earlier
than four weeks postpartum.
Nursing Mothers
When possible, advise the nursing mother to use other
forms of contraception until she has weaned her child. Estrogen-containing 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.
After oral administration of Yasmin, about 0.02% of the
DRSP dose was excreted into the breast milk of postpartum women within 24
hours. This results in a maximal daily dose of about 0.003 mg DRSP in an
infant.
Pediatric Use
Safety and efficacy of Yasmin has been established in
women of reproductive age. Efficacy is expected to be the same for postpubertal
adolescents under the age of 18 and for users 18 years and older. Use of this
product before menarche is not indicated.
Geriatric Use
Yasmin has not been studied in postmenopausal women and
is not indicated in this population.
Patients With Renal Impairment
Yasmin is contraindicated in patients with renal
impairment [see CONTRAINDICATIONS and WARNINGS AND PRECAUTIONS].
In subjects with creatinine clearance (CLcr) of 50–79
mL/min, serum DRSP concentrations were comparable to those in a control group
with CLcr ≥ 80 mL/min. In subjects with CLcr of 30–49 mL/min, serum DRSP
concentrations were on average 37% higher than those in the control group. In
addition, there is a potential to develop hyperkalemia in subjects with renal
impairment whose serum potassium is in the upper reference range, and who are
concomitantly using potassium sparing drugs [see CLINICAL PHARMACOLOGY].
Patients With Hepatic Impairment
Yasmin is contraindicated in patients with hepatic
disease [see CONTRAINDICATIONS and WARNINGS AND PRECAUTIONS]. The
mean exposure to DRSP in women with moderate liver impairment is approximately
three times higher than the exposure in women with normal liver function.
Yasmin has not been studied in women with severe hepatic impairment.
Race
No clinically significant difference was observed between
the pharmacokinetics of DRSP or EE in Japanese versus Caucasian women [see CLINICAL
PHARMACOLOGY].
