This is not an exhaustive list of all potential interactions. Therefore, it is crucial to inform your doctor and pharmacist about:
All medications you are taking, including prescription and over-the-counter drugs, natural products, and vitamins
* Any health problems you have
Ensure that it is safe to take this medication with all your other medications and health conditions. Do not start, stop, or change the dose of any medication without consulting your doctor.
Precautions & Cautions
This medication may increase the risk of blood clots, stroke, or heart attack. Discuss these potential risks with your doctor. If you will be immobile for extended periods, such as during long trips, bedrest after surgery, or illness, inform your doctor, as this may further increase your risk of blood clots.
If you have diabetes (high blood sugar), consult your doctor, as this medication may affect your blood sugar levels. Monitor your blood sugar as directed by your doctor. Additionally, this medication may cause high blood pressure, so have your blood pressure checked regularly as advised by your doctor.
Regular laboratory tests, including blood work, are crucial while taking this medication. Ensure that you have these tests done as scheduled, and inform all your healthcare providers and laboratory personnel that you are taking this medication.
It is also important to maintain regular breast exams and gynecology check-ups, and to perform breast self-exams as instructed by your doctor. Certain medications, herbal products, or health conditions may interfere with the effectiveness of hormone-based birth control. Inform your doctor about all your medications and health issues, and discuss the potential need for non-hormone birth control methods, such as condoms.
If you are allergic to tartrazine (FD&C Yellow No. 5), consult your doctor, as some products contain this ingredient. This medication may also cause elevated cholesterol and triglyceride levels; discuss this with your doctor.
Remember that this medication does not protect against sexually transmitted diseases, such as HIV or hepatitis. Always use latex or polyurethane condoms during sexual activity, and consult your doctor if you have any questions.
There may be a potential increased risk of cervical cancer associated with long-term use of hormone-based birth control, although this may be attributed to other factors. Additionally, some studies suggest a possible link between long-term use of hormone-based birth control and an increased risk of breast cancer, while other studies have not found this association. If you have concerns, discuss them with your doctor.
This medication is not intended for use in children who have not yet had their first menstrual period.
Overdose Information
Overdose Symptoms:
- Nausea
- Vomiting
- Vaginal bleeding (especially in females)
What to Do:
Overdose is generally not life-threatening. Treatment is supportive. Contact a poison control center (1-800-222-1222) or seek emergency medical attention if symptoms are severe or concerning.
Drug Interactions
Contraindicated Interactions
- Ombitasvir/paritaprevir/ritonavir, with or without dasabuvir (risk of ALT elevations)
- Glecaprevir/pibrentasvir (risk of ALT elevations)
Major Interactions
- Strong CYP3A4 inducers (e.g., Rifampin, Phenytoin, Carbamazepine, Barbiturates, Topiramate, Oxcarbazepine, Griseofulvin, St. John's Wort) - may decrease contraceptive efficacy and increase breakthrough bleeding.
- Aromatase inhibitors (e.g., Anastrozole, Letrozole) - may reduce efficacy of aromatase inhibitors.
- Thyroid hormone replacement therapy (e.g., Levothyroxine) - may increase thyroid hormone binding globulin, requiring increased thyroid hormone dose.
Moderate Interactions
- Certain antibiotics (e.g., Ampicillin, Tetracycline) - theoretical risk of reduced efficacy due to altered enterohepatic circulation, though clinical significance is debated; backup contraception often recommended.
- CYP3A4 inhibitors (e.g., Itraconazole, Ketoconazole, Voriconazole, Grapefruit juice) - may increase estrogen/progestin levels, potentially increasing adverse effects.
- Lamotrigine - may decrease lamotrigine levels, leading to loss of seizure control.
- Cyclosporine - may increase cyclosporine levels, increasing toxicity.
Minor Interactions
- Acetaminophen - may increase ethinyl estradiol levels.
- Ascorbic acid (Vitamin C) - may increase ethinyl estradiol levels.
Monitoring
Baseline Monitoring
Rationale: To identify contraindications, risk factors for adverse events (e.g., VTE, cardiovascular disease), and establish baseline health status.
Timing: Prior to initiation of therapy
Rationale: To assess cardiovascular risk, especially in patients with pre-existing dyslipidemia or family history.
Timing: Prior to initiation, if indicated by risk factors
Rationale: To assess hepatic function, as oral contraceptives are contraindicated in severe liver disease.
Timing: Prior to initiation, if indicated by history of liver disease
Routine Monitoring
Frequency: Every 6-12 months
Target: <140/90 mmHg
Action Threshold: Sustained elevation >140/90 mmHg may require discontinuation or change in contraception.
Frequency: Annually
Target: Normal findings
Action Threshold: Abnormal findings require further investigation and potential discontinuation.
Frequency: Annually or as clinically indicated
Target: Stable, healthy BMI
Action Threshold: Significant weight gain may increase cardiovascular risk.
Symptom Monitoring
- ACHES: Abdominal pain (severe)
- Chest pain (severe), shortness of breath, coughing blood
- Headaches (severe, sudden, or worse than usual, especially with visual changes)
- Eye problems (blurred vision, loss of vision, flashing lights)
- Severe leg pain (calf or thigh), swelling, warmth, redness
Special Patient Groups
Pregnancy
Contraindicated. There is no indication for use in pregnancy, and there is evidence of fetal harm. Discontinue immediately if pregnancy is confirmed.
Trimester-Specific Risks:
Lactation
Not recommended. Estrogens can decrease the quantity and quality of breast milk. Small amounts of steroids may pass into breast milk and affect the infant. Non-hormonal methods or progestin-only methods are generally preferred during lactation.
Pediatric Use
Indicated only for post-menarcheal females. Safety and efficacy are similar to adults once menstruation has begun.
Geriatric Use
Not indicated for use in postmenopausal women for contraception. Risks of cardiovascular events increase with age.
Clinical Information
Clinical Pearls
- Emphasize the importance of consistent daily dosing at the same time to maintain efficacy.
- Counsel patients on missed pill instructions thoroughly, as this is a common cause of contraceptive failure.
- Remind patients that oral contraceptives do not protect against STIs.
- Advise patients to report any signs of serious adverse events (e.g., DVT, PE, stroke, MI) immediately using the 'ACHES' mnemonic.
- Be aware of potential drug interactions, especially with enzyme-inducing medications, which can significantly reduce contraceptive efficacy.
Alternative Therapies
- Progestin-only pills (mini-pill)
- Progestin injection (Depo-Provera)
- Progestin implant (Nexplanon)
- Intrauterine devices (IUDs - hormonal or copper)
- Barrier methods (condoms, diaphragm, cervical cap)
- Spermicides
- Surgical sterilization (vasectomy, tubal ligation)
