2 DOSAGE AND ADMINISTRATION Take one tablet daily by mouth at the same time every day for 91 days in the order directed on the blister pack. 1 How to Start and Take CAMRESE Begin CAMRESE on the first Sunday after the onset of menstruation.
If menstruation begins on a Sunday, take the first light blue-green tablet that day. For each 91-day course, take in the following order: 1. Start the first light blue-green tablet on the first Sunday after onset of menstruation. Then take one light blue-green tablet daily for 84 consecutive days.
Use a non-hormonal backup method of contraception (such as condoms and spermicide) until a light blue-green tablet has been taken daily for 7 consecutive days. 2. Then take one yellow tablet for 7 consecutive days. Bleeding should occur during the 7 days that the yellow tablets are taken.
Begin the next and all subsequent 91-day cycles without interruption on the same day of the week (Sunday) on which the patient began her first dose of CAMRESE, following the same schedule: 84 days taking a light blue-green tablet followed by 7 days taking a yellow tablet.
If the patient does not immediately start her next pill pack, instruct her to protect herself from pregnancy by using a non-hormonal backup method of contraception until she has taken a light blue-green tablet daily for 7 consecutive days.
Switching to CAMRESE from another oral hormonal contraceptive or from another contraceptive method (transdermal patch, vaginal ring, injection, intrauterine contraceptive, implant) Start on the Sunday after the patient’s next period starts.
Use additional non-hormonal contraceptive (such as condoms and spermicide) until the patient has taken a light blue-green tablet for 7 consecutive days. Starting CAMRESE after Abortion or Miscarriage First-trimester CAMRESE may be started on the Sunday after an abortion or miscarriage.
The patient must use additional non-hormonal contraception (such as condoms and spermicide) until the patient has taken a light blue-green tablet for 7 consecutive days. Second-trimester Do not start until 4 weeks after a second-trimester abortion or miscarriage, due to the increased risk of thromboembolic disease.
Start contraceptive therapy with CAMRESE following the instructions for women not currently using hormonal contraception. 1 )]. Starting CAMRESE after Childbirth Do not start until 4 weeks after delivery, due to the increased risk of thromboembolic disease.
2 )] The most common adverse reactions (≥5%) in clinical trials for CAMRESE are irregular and/or heavy uterine bleeding, weight gain, and acne. gov/medwatch . 1 Clinical Trial Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to the rates in the clinical trials of another drug and may not reflect the rates observed in practice.
The clinical trial that evaluated the safety and efficacy of CAMRESE was a 12-month, randomized, multicenter, open-label study, which enrolled women aged 18-40, of whom 1,006 took at least one dose of CAMRESE. 0%). Common Treatment-Emergent Adverse Reactions (≥ 5% of women) : irregular and/or heavy uterine bleeding (17%), weight gain (5%), acne (5%).
Serious Adverse Reactions: migraine, cholecystitis, cholelithiasis, pancreatitis, abdominal pain, and major depressive disorder. 12 (Figure 3). Three studies compared breast cancer risk between current or recent COC users (<6 months since last use) and never users of COCs (Figure 3).
One of these studies reported no association between breast cancer risk and COC use. 33 with current or recent use. 4 with more than 8-10 years of COC use.

The following adverse reactions have been identified during post-approval use of CAMRESE. Because these reactions are reported voluntarily from a population of uncertain size, it is not possible to reliably estimate their frequency of establish a causal relationship to drug exposure.
5 WARNINGS AND PRECAUTIONS Vascular risks: Stop if a thrombotic or thromboembolic event occurs. Stop at least 4 weeks before and through 2 weeks after major surgery. Start no earlier than 4 weeks after delivery, in women who are not breastfeeding.
Consider cardiovascular risk factors before initiating in all females, particularly those over 35 years. 5 ) Liver disease: Discontinue if jaundice occurs. 2 ) Hypertension: If used in females with well-controlled hypertension, monitor blood pressure and stop if blood pressure rises significantly.
3 ) Gallbladder disease: May cause or worsen gallbladder disease. 6 ) Adverse carbohydrate and lipid metabolic effects: Monitor glucose in prediabetic and diabetic women taking CAMRESE. Consider an alternate contraceptive method for women with uncontrolled dyslipidemias.
7 ) Headache: Evaluate significant change in headaches and discontinue if indicated. 8 ) Uterine bleeding: May cause irregular bleeding or amenorrhea. Evaluate for other causes if symptoms persist. 1 Thromboembolic Disorders and Other Vascular Conditions Stop CAMRESE if an arterial or deep venous thrombotic/thromboembolic event occurs.
Stop CAMRESE if there is unexplained loss of vision, proptosis, diplopia, papilledema, or retinal vascular lesions and evaluate for retinal vein thrombosis immediately. Discontinue CAMRESE during prolonged immobilization. If feasible, stop CAMRESE at least 4 weeks before and through 2 weeks after major surgery, or other surgeries known to have an elevated risk of thromboembolism.
Start CAMRESE 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.
Before starting CAMRESE evaluate any past medical history or family history of thrombotic or thromboembolic disorders and consider whether the history suggests an inherited or acquired hypercoagulopathy. CAMRESE is contraindicated in women with a high risk of arterial or venous/thromboembolic diseases [see Contraindications ( 4 )] .

Start contraceptive therapy with CAMRESE following the instructions for women not currently using hormonal contraception. 1 )]. 1 )]. 2 Dosing CAMRESE Take one tablet by mouth at the same time every day. The dosage of CAMRESE is one light blue-green tablet daily for 84 consecutive days, followed by one yellow tablet daily for 7 days.
To achieve maximum contraceptive effectiveness, CAMRESE must be taken exactly as directed, in the order directed, and at intervals not exceeding 24 hours. The failure rate may increase when pills are missed or taken incorrectly. 3 Missed Doses Table 1.
Instructions for Missed CAMRESE Tablets If one light blue-green tablet is missed Take the missed tablet as soon as possible. Take the next tablet at the regular time. Continue taking one tablet a day until the pack is finished. A backup birth control method is not required if the patient has sex.
If two light blue-green tablet in a row are missed Take the two missed tablets as soon as possible, and the next two tablets the next day. Continue taking one tablet a day until the pack is finished. Use additional nonhormonal contraception (such as condoms and spermicide) until tablets have been taken for 7 days after missing tablets.
If three or more light blue-green pills in a row are missed Throw away the missed pills. Continue taking one tablet every day as indicated on the pack until the pack is finished. Bleeding may occur during the week following the missed tablets.
Use additional nonhormonal contraception (such as condoms and spermicide) until tablets have been taken for 7 days after missing tablets. If any of the seven yellow tablets are missed Throw away the missed tablets. Continue taking the remaining tablets until the pack is finished.
A backup birth control method is not needed. 4 Advice in Case of Gastrointestinal Disturbances In case of prolonged vomiting or diarrhea, absorption may not be complete and additional contraceptive measures should be taken.
Gastrointestinal disorders: abdominal distension, vomiting General disorders and administration site conditions: chest pain, fatigue, malaise, edema peripheral, pain Immune system disorders: hypersensitivity reaction Investigations: blood pressure increased Musculoskeletal and connective tissue disorders: muscle spasms, pain in extremity Nervous system disorders: dizziness, loss of consciousness Psychiatric disorders: insomnia Reproductive and breast disorders: dysmenorrhea Respiratory, thoracic and mediastinal disorders: pulmonary embolism, pulmonary thrombosis Skin and subcutaneous tissue disorders: alopecia Vascular disorders: thrombosis Figure- Breast cancer Data
Arterial Events COCs increase the risk of cardiovascular events and cerebrovascular events, such as myocardial infarction and stroke. The risk is greater among older women (> 35 years of age), smokers, and females with hypertension, dyslipidemia, diabetes, or obesity.
CAMRESE is contraindicated in women over 35 years of age who smoke [see Contraindications ( 4 )] . Cigarette smoking increases the risk of serious cardiovascular events from COC use. This risk increases with age, particularly in women over 35 years of age, and with the number of cigarettes smoked.
Venous Events Use of COCs increases the risk of venous thromboembolic events (VTEs), such as deep vein thrombosis and pulmonary embolism. Risk factors for VTEs include smoking, obesity, and family history of VTE, in addition to other factors that contraindicate use of CHCs [see Contraindications ( 4 )] .
While the increased risk of VTE associated with use of COCs is well-established, the rates of VTE are even greater during pregnancy, and especially during the postpartum period (see Figure 1). The rate of VTE in females using COCs has been estimated to be 3 to 9 cases per 10,000 woman years.
The risk of VTE is highest during the first year of use of a COC and when restarting hormonal contraception after a break of four weeks or longer. The risk of thromboembolic disease due to COCs gradually disappears after COC use is discontinued.
Figure 1 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, 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. Use of CAMRESE provides women with more hormonal exposure on a yearly basis than conventional monthly oral contraceptives containing the same strength synthetic estrogens and progestins (an additional 9 and 13 weeks of exposure to progestin and estrogen, respectively, per year).
2 Liver Disease Elevated Liver Enzymes CAMRESE is contraindicated in women with acute viral hepatitis or severe (decompensated) cirrhosis of the liver [see Contraindications ( 4 )] . Acute liver test abnormalities may necessitate the discontinuation of CAMRESE until the liver tests return to normal and CAMRESE causation has been excluded.
Discontinue CAMRESE if jaundice develops. Liver Tumors CAMRESE is contraindicated in women with benign or malignant liver tumors [see Contraindications ( 4 )] . COCs increase the risk of hepatic adenomas. 3 cases/100,000 COC users. Rupture of hepatic adenomas may cause death from abdominal hemorrhage.
Studies have shown an increased risk of developing hepatocellular carcinoma in long-term (> 8 years) COC users. The attributable risk of liver cancers in COC users is less than one case per million users. 3 Hypertension CAMRESE is contraindicated in women with uncontrolled hypertension or hypertension with vascular disease [see Contraindications ( 4 )] .
For all women, including those with well-controlled hypertension, monitor blood pressure at routine visits and stop CAMRESE if blood pressure rises significantly. 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 effect of COCs on blood pressure may vary according to the progestin in the COC. 4 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 CAMRESE.
Discontinue CAMRESE prior to starting therapy with the combination drug regimen ombitasvir/paritaprevir/ritonavir, with or without dasabuvir [see Contraindications ( 4 )]. CAMRESE can be restarted approximately 2 weeks following completion of treatment with the Hepatitis C combination drug regimen.
5 Age-related Considerations The risk for cardiovascular disease and prevalence of risk factors for cardiovascular disease increases with age. 1 )] . 6 Gallbladder Disease Studies suggest a small increased relative risk of developing gallbladder disease among COC users.
Use of COCs, including CAMRESE, may also worsen existing gallbladder disease. A past history of COC-related cholestasis predicts an increased risk with subsequent COC use. Females with a history of pregnancy-related cholestasis may be at an increased risk for COC-related cholestasis.
7 Adverse Carbohydrate and Lipid Metabolic Effects Hyperglycemia CAMRESE is contraindicated in diabetic women over age 35, or females who have diabetes with hypertension, nephropathy, retinopathy, neuropathy, other vascular disease, or females with diabetes of > 20 years duration [see Contraindications ( 4 )] .
CAMRESE may decrease glucose tolerance. Carefully monitor prediabetic and diabetic women who are taking CAMRESE. Dyslipidemia Consider alternative contraception for women with uncontrolled dyslipidemia. CAMRESE may cause adverse lipid changes.
Women with hypertriglyceridemia, or a family history thereof, may have an increase in serum triglyceride concentrations when using CAMRESE, which may increase the risk of pancreatitis. 8 Headache CAMRESE is contraindicated in females who have headaches with focal neurological symptoms or have migraine headaches with aura, and in women over 35 years of age who have migraine headaches with or without aura [see Contraindications ( 4 )] .
If a woman taking CAMRESE develops new headaches that are recurrent, persistent, or severe, evaluate the cause and discontinue CAMRESE if indicated. Consider discontinuation of CAMRESE if there is an increased frequency or severity of migraine during COC use (which may be prodromal of a cerebrovascular event).
9 Bleeding Irregularities and Amenorrhea Unscheduled Bleeding and Spotting Women using CAMRESE may experience unscheduled (breakthrough or intracyclic) bleeding and spotting, especially during the first 3 months of use. Bleeding irregularities may resolve over time or by changing to a different contraceptive product.
If unscheduled bleeding persists or occurs after previously regular cycles, evaluate for causes such as pregnancy or malignancy. When prescribing CAMRESE, the occurrence of fewer planned menses (4 per year instead of 13 per year) should be weighed against the occurrence of increased unscheduled bleeding and/or spotting.
The primary clinical trial (PSE-301) that evaluated the efficacy of CAMRESE also assessed unscheduled bleeding. The participants in the 12-month clinical trial (N=1,006) completed the equivalent of 8,681 28-day cycles of exposure and were composed primarily of women who had used oral contraceptives previously (89%) as opposed to new users (11%).
2%) of the women discontinued CAMRESE, at least in part, due to bleeding or spotting. Scheduled (withdrawal) bleeding and/or spotting remained fairly constant over time, with an average of 3 days of bleeding and/or spotting per each 91-day cycle.
Unscheduled bleeding and unscheduled spotting decreased over successive 91-day cycles. Table 1 below presents the number of days with unscheduled bleeding in treatment cycles 1 and 4. Table 2 presents the number of days with unscheduled spotting in treatment cycles 1 and 4.
1 Q1=Quartile 1: 25% of women had ≤ this number of days of unscheduled spotting Median: 50% of women had ≤ this number of days of unscheduled spotting Q3=Quartile 3: 75% of women had ≤ this number of days of unscheduled spotting Figure 2 shows the percentage of CAMRESE subjects participating in trial PSE-301 with ≥ 7 days or ≥ 20 days of unscheduled bleeding and/or spotting, or only unscheduled bleeding, during each 91-day treatment cycle.
Figure 2:
Percent of Women Taking CAMRESE who Reported Unscheduled Bleeding and/or Spotting or only Unscheduled Bleeding If unscheduled spotting or bleeding occurs, instruct the patient to continue on the same regimen. If the bleeding is persistent or prolonged, advise the patient to consult her healthcare provider.
Amenorrhea and Oligomenorrhea Women who use CAMRESE may experience absence of scheduled (withdrawal) bleeding, even if they are not pregnant. If scheduled bleeding does not occur, consider the possibility of pregnancy. After discontinuation of CAMRESE, amenorrhea or oligomenorrhea may occur, especially if these conditions were pre-existent.
10 Depression Carefully observe women with a history of depression and discontinue CAMRESE if depression recurs to a serious degree. Data on the association of COCs with the onset of depression or exacerbation of existing depression are limited.
11 Malignant Neoplasms Breast Cancer CAMRESE is contraindicated in females who currently have or have had breast cancer because breast cancer may be hormonally sensitive [see Contraindications ( 4 )]. 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. 2 )] . Cervical Cancer 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 are due to differences in sexual behavior and other factors. 12 Effect on Binding Globulins The estrogen component of CAMRESE may raise the serum concentrations of thyroxine-binding globulin, sex hormone-binding globulin, and cortisol-binding globulin.
The dose of replacement thyroid hormone or cortisol therapy may need to be increased. 13 Hereditary Angioedema In females with hereditary angioedema, exogenous estrogens, including CAMRESE, may induce or exacerbate symptoms of hereditary angioedema.
14 Chloasma Chloasma may occur with CAMRESE use, especially in women with a history of chloasma gravidarum. Advise women with a history of chloasma to avoid exposure to the sun or ultraviolet radiation while using CAMRESE.
