Warnings and Precautions
PRECAUTIONS
(Additions and/or revisions are underlined)
3. Gastrointestinal
Diarrhea and/or
vomiting within 4 hours after taking a pill may reduce hormone
absorption. Women should use of a nonhormonal back-up method of birth
control (such as a condom or spermicide) during the next 48 hours.
6. Carbohydrate
and Lipid Effects
Some Opill
Tablets users may experience slight changes in glucose tolerance
with increases in plasma insulin, but women with diabetes mellitus who use
progestin-only oral contraceptives do not generally experience changes in their
insulin requirements.
The effect
of progestin-only oral
contraceptives on carbohydrate
and lipid metabolism
is generally not
clinically significant.
WARNINGS
(Additions and/or revisions are underlined)
2. Delayed
Follicular Atresia/Ovarian Cysts
Often they are
asymptomatic; in some cases they are associated with mild abdominal pain, and
rarely they may twist or rupture, requiring surgical intervention.
3. Bleeding
Pattern Alterations
Irregular menstrual
patterns are common among women using Opill Tablets. Undiagnosed abnormal
uterine bleeding should be evaluated before Opill is prescribed. In the 8 U.S.
clinical trials of Opill Tablets, there were a total of 2,575 enrolled
subjects, and approximately half of them experienced some menstrual changes.
This was defined in the clinical studies as vaginal bleeding which, in the judgment of the subject, did not have
the characteristics of her pre-treatment menstrual periods in duration, amount
or appearance. Subjects experienced unscheduled (breakthrough) bleeding
(48.6%) and spotting (47.3%) on Opill
Tablets. Amenorrhea occurred in 6.1% of subjects in their first cycle and 28.7%
of all subjects during the studies. A total of 379 participants (17.4%)
discontinued treatment due to side effects; 67.6% of all discontinuations were
due to bleeding patterns. Overall, 6.4% of participants discontinued treatment
due to breakthrough bleeding and 2.7% due to amenorrhea (n=2,173 subjects who
completed at least one cycle).
If uterine bleeding
together with the clinical history is suggestive of infection,
malignancy, pregnancy, or other conditions, rule out these conditions. If
amenorrhea occurs, consider the possibility of pregnancy.
4. Hepatic
Neoplasia/Liver Disease
Discontinue
Opill Tablet use if jaundice or acute disturbances of liver function develop.
Do not resume use until markers of liver function return to normal and Opill
Tablet causation has been excluded.

Adverse Reactions
(Additions and/or revisions are underlined)
The following adverse
reactions were reported in greater than or equal to 5% of subjects in the
Opill Tablet clinical studies:

Drug Interactions
(Additions and/or revisions are underlined)
- The effectiveness of progestin-only pills is reduced by hepatic
enzyme-inducing drugs such as phenytoin, carbamazepine, barbiturates,
rifampin, efavirenz, bosentan and herbal preparations containing
St. John’s Wort (hypericum perforatum).
During concomitant
use of Opill and substances that may affect its efficacy, it is
recommended that a nonhormonal back-up method of contraception (such as
condom) be used in addition to the regular intake of Opill Tablets.
Use of a nonhormonal back-up method is
recommeded for 28 days after discontinuation of substances that have led
to induction of hepatic microsomal enzymes.
- Effectiveness of progestin-containing hormonal contraceptives and
emergency contraceptive ulipristal acetate may be decreased if
progestin-containing hormonal contraceptives are used within five days
after ulipristal acetate dosing.
If a woman wishes
to use Opill Tablets after using ulipristal acetate, she should do so no sooner
than 5 days after the intake of ulipristal acetate and she should use a
reliable barrier method for subsequent acts of intercourse until her next
menstrual period.

Use in Specific Populations
(Additions and/or revisions are underlined)
Pregnancy
Opill Tablets
are contraindicated for use in pregnant women because there is no need for
pregnancy prevention in a woman who is already pregnant. Published studies report no harmful
effects on fetal development associated with long-term use of contraceptive
doses of oral progestins in pregnant women.
Discontinue
Opill Tablets if pregnancy is confirmed.
Nursing Mothers
Small amounts of
progestin pass into the breast milk, resulting in steroid levels in infant
plasma. No adverse effects have been reported on breastfeeding performance or
infant health. The developmental and health benefits of breastfeeding should be
considered along with the mother’s clinical need for Opill Tablets and any
potential adverse effects on the breastfed infant from Opill Tablets or from
the underlying maternal condition.
Pediatric Use
Safety and efficacy
of Opill Tablets have been established in women of reproductive age, including
adolescents as young as 15 years of age, and almost 30% of subjects in the
clinical trials who were under 20 years of age. Use of this product before
menarche is not indicated.
Geriatric Use
Opill Tablets has not been studied in postmenopausal
women and is not indicated in this population.
