Interactions

The sections below provide information on substances for which data on drug interactions with COCs are available. There is little information available about the clinical effect of most drug interactions that may affect COCs. However, based on the known pharmacokinetic effects of these drugs, clinical strategies to minimize any potential adverse effect on contraceptive effectiveness or safety are suggested. Consult the approved product labeling of all concurrently used drugs to obtain further information about interactions with COCs or the potential for metabolic enzyme or transporter system alterations.

No formal drug-drug interaction studies were conducted with CAMRESE LO. Enzyme inducers (e.g., CYP3A4): May decrease the effectiveness of CAMRESE LO or increase breakthrough bleeding. Counsel patients to use a backup method or alternative method of contraception when enzyme inducers are used with CAMRESE LO. ( 7.1 )

7.1 Effects of Other Drugs on Combined Oral Contraceptives Substances Decreasing the Plasma Concentrations of COCs and Potentially Diminishing the Efficacy of COCs: Table 4 includes substances that demonstrated an important drug interaction with CAMRESE LO. Table 4: Significant Drug Interactions Involving Substances That Affect COCs Metabolic Enzyme Inducers Clinical effect Concomitant use of COCs with metabolic enzyme inducers may decrease the plasma concentrations of the estrogen and/or progestin component of COCs.

Decreased exposure of the estrogen and/or progestin component of COCs may potentially diminish the effectiveness of COCs and may lead to contraceptive failure or an increase in breakthrough bleeding. Prevention or management Counsel females to use an alternative method of contraception or a backup method when enzyme inducers are used with COCs. Continue backup contraception for 28 days after discontinuing the enzyme inducer to maintain contraceptive reliability.

Examples Aprepitant, barbiturates, bosentan, carbamazepine, efavirenz, felbamate, griseofulvin, oxcarbazepine, phenytoin, rifampin, rifabutin, rufinamide, topiramate, products containing St. John’s wort a , and certain protease inhibitors (see separate section on protease inhibitors below). Colesevelam Clinical effect Concomitant use of COCs with colesevelam significantly decreases systemic exposure of ethinyl estradiol.

Decreased exposure of the estrogen component of COCs may potentially reduce contraceptive efficacy or result in an increase in breakthrough bleeding, depending on the strength of ethinyl estradiol in the COC. Prevention or management Administer 4 or more hours apart to attenuate this drug interaction. a Induction potency of St. John’s wort may vary widely based on preparation. Substances increasing the systemic exposure of COCs: Co-administration of atorvastatin or rosuvastatin and COCs containing ethinyl estradiol increase systemic exposure of ethinyl estradiol by approximately 20 to 25 percent.

Ascorbic acid and acetaminophen may increase systemic exposure of ethinyl estradiol, possibly by inhibition of conjugation. CYP3A inhibitors such as itraconazole, voriconazole, fluconazole, grapefruit juice, or ketoconazole may increase systemic exposure of the estrogen and/or progestin component of COCs. Human immunodeficiency virus (HIV)/hepatitis C virus (HCV) protease inhibitors and non-nucleoside reverse transcriptase inhibitors: Significant decreases in systemic exposure of the estrogen and/or progestin have been noted when COCs are co-administered with some HIV protease inhibitors (e.g., nelfinavir, ritonavir, darunavir/ritonavir, (fos)amprenavir/ritonavir, lopinavir/ritonavir, and tipranavir/ritonavir), some HCV protease inhibitors (e.g., boceprevir and telaprevir), and some non-nucleoside reverse transcriptase inhibitors (e.g., nevirapine).

In contrast, significant increases in systemic exposure of the estrogen and/or progestin have been noted when COCs are co-administered with certain other HIV protease inhibitors (e.g., indinavir and atazanavir/ritonavir) and with other non-nucleoside reverse transcriptase inhibitors (e.g., etravirine).

7.2Effects of Combined Oral Contraceptives on Other Drugs Table

5 provides significant drug interaction information for drugs co-administered with CAMRESE LO. Table 5: Significant Drug Interaction Information for Drugs Co-Administered With COCs Lamotrigine Clinical effect Concomitant use of COCs with lamotrigine may significantly decrease systemic exposure of lamotrigine due to induction of lamotrigine glucuronidation. Decreased systemic exposure of lamotrigine may reduce seizure control.

Prevention or management Dose adjustment may be necessary. Consult the approved product labeling for lamotrigine. Thyroid Hormone Replacement Therapy or Corticosteroid Replacement Therapy Clinical effect Concomitant use of COCs with thyroid hormone replacement therapy or corticosteroid replacement therapy may increase systemic exposure of thyroid-binding and cortisol-binding globulin [see Warnings and Precautions ( 5.12 )] .

Prevention or management The dose of replacement thyroid hormone or cortisol therapy may need to be increased. Consult the approved product labeling for the therapy in use [see Warnings and Precautions ( 5.12 )] . Other Drugs Clinical effect Concomitant use of COCs may decrease systemic exposure of acetaminophen, morphine, salicylic acid, and temazepam. Concomitant use with ethinyl estradiol-containing COCs may increase systemic exposure of other drugs (e.g., cyclosporine, prednisolone, theophylline, tizanidine, and voriconazole).

Prevention or management The dosage of drugs that can be affected by this interaction may need to be increased. Consult the approved product labeling for the concomitantly used drug.

7.3Concomitant Use with Hepatitis C Virus (HCV) Combination

Therapy – Liver Enzyme Elevation Co-administration of CAMRESE LO with HCV drug combinations containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir is contraindicated due to potential for ALT elevations [see Warnings and Precautions ( 5.4 )] . Co-administration of CAMRESE LO and glecaprevir/pibrentasvir is not recommended due to potential for ALT elevations.

7.4Effect on Laboratory Tests

The use of COCs may influence the results of certain laboratory tests, such as coagulation factors, lipids, glucose tolerance, and binding proteins.

Adverse reactions

The following serious adverse reactions with the use of COCs are discussed elsewhere in the labeling: Serious cardiovascular events and stroke [see Boxed Warning and Warnings and Precautions ( 5.1 )] Vascular events [see Warnings and Precautions ( 5.1 )] Liver disease [see Warnings and Precautions ( 5.2 )] The most common adverse reactions in clinical trials for CAMRESE LO were headaches, irregular and/or heavy uterine bleeding, dysmenorrhea, nausea and/or vomiting and back pain.

6.1Clinical 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 LO was a 12-month, multicenter, non-comparative open-label study, which enrolled women aged 18-41, of whom 2,185 took at least one dose of CAMRESE LO.

Adverse Reactions Leading to Study Discontinuation: 11% of the women discontinued from the clinical trial due to an adverse reaction; the most common adverse reactions leading to discontinuation were irregular and/or heavy uterine bleeding, headache, mood changes, nausea, acne, and weight gain. Common Treatment-Emergent Adverse Reactions (≥5% of women): headaches (33%); irregular and/or heavy uterine bleeding (13%), dysmenorrhea (11%), nausea and/or vomiting (11%), back pain (8%).

6.2Postmarketing 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 - 1.12 (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 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 - 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 8-10 years of COC use. Figure 3: 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.
