Dosage & Administration of Viorele

To achieve maximum contraceptive effectiveness, VIORELE ® (desogestrel and ethinyl estradiol tablets, USP and ethinyl estradiol tablets, USP) must be taken exactly as directed and at intervals not exceeding 24 hours. VIORELE ® may be initiated using either a Sunday start or a Day 1 start. NOTE: Each cycle pack blister 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 cycle pack blister 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 VIORELE ® should be considered.

The use of VIORELE ® 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 VIORELE ® 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 pale green to yellowish green (inert) tablet daily for 2 days and 1 light yellow to yellow (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 yellow to yellow 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 cycle 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 cycle pack and start a new cycle 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 pale green to yellowish green (inert) tablet daily for 2 days followed by 1 light yellow to yellow (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 yellow to yellow 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 cycle 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 cycle pack and start a new cycle 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.

Side Effects of Viorele

  • 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). (64, 67, 69) 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.

Adapted from H.W. Ory, ref. #35. a) Deaths are birth related b)

Deaths are method related 3. Malignant Neoplasms Breast Cancer VIORELE ® is contraindicated in females who currently have or have had breast cancer because breast cancer may be hormonally sensitive (see Contraindications ). 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 ADVERSE REACTIONS, Postmarketing Experience ). Cervical Cancer Some studies suggest that oral contraceptive use has been associated with an increase in the risk of cervical intra-epithelial neoplasia in some populations of women.

However, there continues to be controversy about the extent to which such findings may be due to differences in sexual behavior and other factors. 4. Hepatic neoplasia Benign hepatic adenomas are associated with oral contraceptive use, although the incidence of benign tumors is rare in the United States. Indirect calculations have estimated the attributable risk to be in the range of 3.3 cases/100,000 for users, a risk that increases after four or more years of use especially with oral contraceptives of higher dose. Rupture of rare, benign, hepatic adenomas may cause death through intra-abdominal hemorrhage.

Studies from Britain have shown an increased risk of developing hepatocellular carcinoma (43-45) in long-term (> 8 years) oral contraceptive users. However, these cancers are extremely rare in the US and the attributable risk (the excess incidence) of liver cancers in oral contraceptive users approaches less than one per million users. 5. Risk of Liver Enzyme Elevations with Concomitant Hepatitis C Treatment During clinical trials with the Hepatitis C combination drug regimen that contains ombitasvir/paritaprevir/ritonavir, with or without dasabuvir, ALT elevations greater than 5 times the upper limit of normal (ULN), including some cases greater than 20 times the ULN, were significantly more frequent in women using ethinyl estradiol-containing medications such as COCs. Discontinue VIORELE ® prior to starting therapy with the combination drug regimen ombitasvir/paritaprevir/ritonavir, with or without dasabuvir.

VIORELE ® can be restarted approximately 2 weeks following completion of treatment with the combination drug regimen. 6. 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. Appropriate diagnostic and therapeutic measures should be undertaken immediately. 7. Oral contraceptive 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 (55-57). 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.

The administration of oral contraceptives to induce withdrawal bleeding should not be used as a test for pregnancy. Oral contraceptives should not be used during pregnancy to treat threatened or habitual abortion. It is recommended that for any patient who has missed two consecutive periods, pregnancy should be ruled out before continuing oral contraceptive use.

If the patient has not adhered to the prescribed schedule, the possibility of pregnancy should be considered at the first missed period. Oral contraceptive use should be discontinued until pregnancy is ruled out. 8. Gallbladder disease Earlier studies have reported an increased lifetime relative risk of gallbladder surgery in users of oral contraceptives and estrogens. More recent studies, however, have shown that the relative risk of developing gallbladder disease among oral contraceptive users may be minimal (62-64). The recent findings of minimal risk may be related to the use of oral contraceptive formulations containing lower hormonal doses of estrogens and progestogens. 9. Carbohydrate and lipid metabolic effects Oral contraceptives have been shown to cause a decrease in glucose tolerance in a significant percentage of users.

Oral contraceptives containing greater than 75 micrograms of estrogens cause hyper-insulinism, while lower doses of estrogen cause less glucose intolerance. Progestogens increase insulin secretion and create insulin resistance, this effect varying with different progestational agents. However, in the non-diabetic woman, oral contraceptives appear to have no effect on fasting blood glucose.

Because of these demonstrated effects, prediabetic and diabetic women should be carefully monitored while taking oral contraceptives. A small proportion of women will have persistent hypertriglyceridemia while on the pill. As discussed earlier (see WARNINGS 1.a. and 1.d.), changes in serum triglycerides and lipoprotein levels have been reported in oral contraceptive users. 10. Elevated blood pressure An increase in blood pressure has been reported in women taking oral contraceptives and this increase is more likely in older oral contraceptive users and with continued use.

Data from the Royal College of General Practitioners and subsequent randomized trials have shown that the incidence of hypertension increases with increasing quantities of progestogens. Women with a history of hypertension or hypertension-related diseases, or renal disease should be encouraged to use another method of contraception. If women elect to use oral contraceptives, they should be monitored closely and if significant elevation of blood pressure occurs, oral contraceptives should be discontinued.

For most women, elevated blood pressure will return to normal after stopping oral contraceptives, and there is no difference in the occurrence of hypertension between ever- and never-users. 11. Headache The onset or exacerbation of migraine or development of headache with a new pattern which is recurrent, persistent, or severe requires discontinuation of oral contraceptives and evaluation of the cause. 12. Bleeding irregularities Breakthrough bleeding and spotting are sometimes encountered in patients on oral contraceptives, especially during the first three months of use. Non-hormonal causes should be considered and adequate diagnostic measures taken to rule out malignancy or pregnancy in the event of breakthrough bleeding, as in the case of any abnormal vaginal bleeding. If pathology has been excluded, time or a change to another formulation may solve the problem.

In the event of amenorrhea, pregnancy should be ruled out. Some women may encounter post-pill amenorrhea or oligomenorrhea, especially when such a condition was pre-existent. 13. Depression Carefully observe women with a history of depression and discontinue VIORELE if depression recurs to a serious degree. 14. Hereditary Angioedema In females with hereditary angioedema, exogenous estrogens may induce or exacerbate symptoms of angioedema. 15. Chloasma Chloasma may occur with VIORELE use, especially in females with a history of chloasma gravidarum. Advise females with a history of chloasma to avoid exposure to the sun or ultraviolet radiation while using VIORELE.

Drug Interactions with Viorele

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 VIORELE ® with HCV drug combinations containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir is contraindicated, due to potential for ALT elevations (see CONTRAINDICATION S, WARNINGS, RISK OF LIVER ENZYME ELEVATIONS WITH CONCOMITANT HEPATITIS C TREATMENT). Co-administration of VIORELE ® 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.

Pregnancy Safety for Viorele

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

Pediatric Use of Viorele

12. Pediatric use Safety and efficacy of VIORELE ® has been established in women of reproductive age. Safety and efficacy are expected to be the same for post-pubertal adolescents under the age of 16 and for users 16 years and older. Use of this product before menarche is not indicated.

  • 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
