Simliya Drug Information

To achieve maximum contraceptive effectiveness, SIMLIYA TM (desogestrel and ethinyl estradiol tablets and ethinyl estradiol tablets) must be taken exactly as directed and at intervals not exceeding 24 hours. SIMLIYA TM may be initiated using either a Sunday start or a Day 1 start. NOTE: Each blister pack is preprinted with the days of the week, starting with Sunday, to facilitate a Sunday start regimen.

Six different “day label strips” are provided with each blister pack in order to accommodate a Day 1 start regimen. In this case, the patient should place the self-adhesive “day label strip” that corresponds to her starting day over the preprinted days. IMPORTANT: The possibility of ovulation and conception prior to initiation of use of SIMLIYA TM should be considered.

The use of SIMLIYA TM for contraception may be initiated 4 weeks postpartum in women who elect not to breast-feed. When the tablets are administered during the postpartum period, the increased risk of thromboembolic disease associated with the postpartum period must be considered (see CONTRAINDICATIONS and WARNINGS concerning thromboembolic disease. See also PRECAUTIONS for Nursing mothers). If the patient starts on SIMLIYA TM postpartum, and has not yet had a period, she should be instructed to use another method of contraception until a white to off-white tablet has been taken daily for 7 days.

SUNDAY START When initiating a Sunday start regimen, another method of contraception should be used until after the first 7 consecutive days of administration. Using a Sunday start, tablets are taken daily without interruption as follows: The first white to off-white tablet should be taken on the first Sunday after menstruation begins (if menstruation begins on Sunday, the first white to off-white tablet is taken on that day). One white to off-white tablet is taken daily for 21 days, followed by 1 green (inert) tablet daily for 2 days and 1 light blue (active) tablet daily for 5 days. For all subsequent cycles, the patient then begins a new 28-tablet regimen on the next day (Sunday) after taking the last light blue tablet.

If a patient misses 1 white to off-white tablet, she should take the missed tablet as soon as she remembers. If the patient misses 2 consecutive white to off-white tablets in Week 1 or Week 2, the patient should take 2 tablets the day she remembers and 2 tablets the next day; thereafter, the patient should resume taking 1 tablet daily until she finishes the blister pack. The patient should be instructed to use a back-up method of birth control if she has intercourse in the 7 days after missing pills.

If the patient misses 2 consecutive white to off-white tablets in the third week or misses 3 or more white to off-white tablets in a row at any time during the cycle, the patient should keep taking 1 white to off-white tablet daily until the next Sunday. On Sunday the patient should throw out the rest of that blister pack and start a new blister pack that same day. The patient should be instructed to use a back-up method of birth control if she has intercourse in the 7 days after missing pills.

DAY 1 START Counting the first day of menstruation as “Day 1”, tablets are taken without interruption as follows: One white to off-white tablet daily for 21 days, one green (inert) tablet daily for 2 days followed by 1 light blue (ethinyl estradiol) tablet daily for 5 days. For all subsequent cycles, the patient then begins a new 28-tablet regimen on the next day after taking the last light blue tablet. If a patient misses 1 white to off-white tablet, she should take the missed tablet as soon as she remembers.

If the patient misses 2 consecutive white to off-white tablets in Week 1 or Week 2, the patient should take 2 tablets the day she remembers and 2 tablets the next day; thereafter, the patient should resume taking 1 tablet daily until she finishes the blister pack. The patient should be instructed to use a back-up method of birth control if she has intercourse in the 7 days after missing pills. If the patient misses 2 consecutive white to off-white tablets in the third week or if the patient misses 3 or more white to off-white tablets in a row at any time during the cycle, the patient should throw out the rest of that blister pack and start a new blister pack that same day.

The patient should be instructed to use a back-up method of birth control if she has intercourse in the 7 days after missing pills. ALL ORAL CONTRACEPTIVES Breakthrough bleeding, spotting, and amenorrhea are frequent reasons for patients discontinuing oral contraceptives. In breakthrough bleeding, as in all cases of irregular bleeding from the vagina, non-functional causes should be borne in mind.

In undiagnosed persistent or recurrent abnormal bleeding from the vagina, adequate diagnostic measures are indicated to rule out pregnancy or malignancy. If both pregnancy and pathology have been excluded, time or a change to another preparation may solve the problem. Changing to an oral contraceptive with a higher estrogen content, while potentially useful in minimizing menstrual irregularity, should be done only if necessary since this may increase the risk of thromboembolic disease.

Use of oral contraceptives in the event of a missed menstrual period: 1. If the patient has not adhered to the prescribed schedule, the possibility of pregnancy should be considered at the time of the first missed period and oral contraceptive use should be discontinued until pregnancy is ruled out. 2. If the patient has adhered to the prescribed regimen and misses two consecutive periods, pregnancy should be ruled out before continuing oral contraceptive use.

An increased risk of the following serious adverse reactions has been associated with the use of oral contraceptives (see WARNINGS section): Thrombophlebitis and venous thrombosis with or without embolism Arterial thromboembolism Pulmonary embolism Myocardial infarction Cerebral hemorrhage Cerebral thrombosis Hypertension Gallbladder disease Hepatic adenomas or benign liver tumors Post Marketing Experience Five studies that compared breast cancer risk between ever-users (current or past use) of COCs and never-users of COCs reported no association between ever use of COCs and breast cancer risk, with effect estimates ranging from 0.90 to 1.12 (Figure 2) (64 to 68). Three studies compared breast cancer risk between current or recent COC users (<6 months since last use) and never users of COCs (Figure 2). One of these studies reported no association between breast cancer risk and COC use. The other two studies found an increased relative risk of 1.19 to 1.33 with current or recent use. Both of these studies found an increased risk of breast cancer with current use of longer duration, with relative risks ranging from 1.03 with less than one year of COC use to approximately 1.4 with more than 8 to 10 years of COC use.

FIGURE 2: RELEVANT STUDIES OF RISK OF BREAST CANCER WITH COMBINED ORAL CONTRACEPTIVES RR = relative risk; OR = odds ratio; HR = hazard ratio. “ever COC” are females with current or past COC use; “never COC use” are females that never used COCs. There is evidence of an association between the following conditions and the use of oral contraceptives: Mesenteric thrombosis Retinal thrombosis The following adverse reactions have been reported in patients receiving oral contraceptives and are believed to be drug-related: Nausea Vomiting Gastrointestinal symptoms (such as abdominal cramps and bloating) Breakthrough bleeding Spotting Change in menstrual flow Amenorrhea Temporary infertility after discontinuation of treatment Edema Melasma which may persist Breast changes: tenderness, enlargement, secretion Change in weight (increase or decrease) Change in cervical erosion and secretion Diminution in lactation when given immediately postpartum Cholestatic jaundice Migraine Rash (allergic) Mental depression Reduced tolerance to carbohydrates Vaginal candidiasis Change in corneal curvature (steepening) Intolerance to contact lenses The following adverse reactions have been reported in users of oral contraceptives and the association has been neither confirmed nor refuted: Pre-menstrual syndrome Cataracts Changes in appetite Cystitis-like syndrome Headache Nervousness Dizziness Hirsutism Loss of scalp hair Erythema multiforme Erythema nodosum Hemorrhagic eruption Vaginitis Porphyria Impaired renal function Hemolytic uremic syndrome Acne Changes in libido Colitis Budd-Chiari Syndrome FIGURE 2: RELEVANT STUDIES OF RISK OF BREAST CANCER WITH COMBINED ORAL CONTRACEPTIVES

7. Drug interactions Reduced efficacy and increased incidence of breakthrough bleeding and menstrual irregularities have been associated with concomitant use of rifampin. A similar association, though less marked, has been suggested with barbiturates, phenylbutazone, phenytoin sodium, carbamazepine and possibly with griseofulvin, ampicillin, and tetracyclines. Combined hormonal contraceptives have been shown to significantly decrease plasma concentrations of lamotrigine when co-administered, likely due to induction of lamotrigine glucuronidation.

This may reduce seizure control; therefore, dosage adjustments of lamotrigine may be necessary. Concomitant Use with Hepatitis C Virus (HCV) Combination Therapy – Liver Enzyme Elevation Co-administration of SIMLIYA TM with HCV drug combinations containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir is contraindicated due to potential for ALT elevations ( see CONTRAINDICATIONS and WARNINGS, RISK OF LIVER ENZYME ELEVATIONS WITH CONCOMITANT HEPATITIS C TREATMENT ). Co-administration of SIMLIYA TM and glecaprevir/pibrentasvir is not recommended due to potential for ALT elevations. Consult the labeling of the concurrently-used drug to obtain further information about interactions with hormonal contraceptives or the potential for enzyme alterations.

10. Pregnancy Discontinue SIMLIYA TM if pregnancy occurs because there is no reason to use COCs in pregnancy. See WARNINGS section.

12. Pediatric use Safety and efficacy of SIMLIYA TM (desogestrel and ethinyl estradiol tablets and ethinyl estradiol tablets) have been established in women of reproductive age. Safety and efficacy are expected to be the same for postpubertal adolescents under the age of 16 and for users 16 years and older. Use of this product before menarche is not indicated.

Oral contraceptives should not be used in women who currently have the following conditions: Thrombophlebitis or thromboembolic disorders A past history of deep vein thrombophlebitis or thromboembolic disorders Cerebral vascular or coronary artery disease Current diagnosis of, or history of, breast cancer, which may be hormone-sensitive Undiagnosed abnormal genital bleeding Cholestatic jaundice of pregnancy or jaundice with prior pill use Hepatic adenomas or carcinomas Are receiving Hepatitis C drug combinations containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir, due to the potential for ALT elevations (see Warnings, RISK OF LIVER ENZYME ELEVATIONS WITH CONCOMITANT HEPATITIS C TREATMENT )

Serious ill effects have not been reported following acute ingestion of large doses of oral contraceptives by young children. Overdosage may cause nausea, and withdrawal bleeding may occur in females. NON-CONTRACEPTIVE HEALTH BENEFITS The following non-contraceptive health benefits related to the use of oral contraceptives are supported by epidemiologic studies which largely utilized oral contraceptive formulations containing estrogen doses exceeding 0.035 mg of ethinyl estradiol or 0.05 mg of mestranol (73 to 78). Effects on menses: increased menstrual cycle regularity decreased blood loss and decreased incidence of iron deficiency anemia decreased incidence of dysmenorrhea Effects related to inhibition of ovulation: decreased incidence of functional ovarian cysts decreased incidence of ectopic pregnancies Effects from long-term use: decreased incidence of fibroadenomas and fibrocystic disease of the breast decreased incidence of acute pelvic inflammatory disease decreased incidence of endometrial cancer decreased incidence of ovarian cancer
