Overview
What is this medicine?
How to Use This Medicine
To get the most out of your medication, follow your doctor's instructions carefully. Read all the information provided with your prescription and follow the instructions closely. Take your medication at the same time every day. You can take it with or without food, but if it upsets your stomach, take it with food.
If you're also taking colesevelam, be sure to take it at least 4 hours before or after taking this medication. After starting this medication, you may need to use a non-hormone form of birth control, such as condoms, to prevent pregnancy for a while. Follow your doctor's advice on using non-hormone birth control.
It's essential to take your medication as directed, even if you don't have sex frequently. Don't skip doses, as this can reduce the medication's effectiveness in preventing pregnancy. If you vomit or have diarrhea, the medication may not work as well. If this happens within 3 to 4 hours after taking an active tablet, take another tablet. If vomiting or diarrhea persists for more than a day, use an extra form of birth control and consult your doctor. If you're unsure what to do, call your doctor for guidance.
If you miss two periods in a row, take a pregnancy test before starting a new cycle of medication.
Storing and Disposing of Your Medication
Store your medication at room temperature, away from light and moisture. Keep it in a dry place, and avoid storing it in a bathroom.
Missing a Dose
If you miss a dose, refer to the package insert or call your doctor for advice on what to do. If you're using this medication to prevent pregnancy, you may need to use a non-hormone form of birth control, such as condoms, for a while to prevent pregnancy.
Lifestyle & Tips
- Take one tablet at the same time every day, without missing any doses, to ensure maximum effectiveness.
- Do not smoke, especially if you are over 35 years old, as smoking significantly increases the risk of serious side effects like blood clots, heart attack, and stroke.
- Use a backup method of birth control (like condoms) for the first 7 days when starting the pill, or if you miss pills.
- This medication does not protect against HIV/AIDS or other sexually transmitted infections (STIs). Use condoms to protect against STIs.
- Inform your doctor about all medications, supplements, and herbal products you are taking, as some can reduce the effectiveness of birth control pills.

Drug Interactions
Contraindicated Interactions
- Ombitasvir/paritaprevir/ritonavir with or without dasabuvir (used for Hepatitis C)
- Glecaprevir/pibrentasvir (used for Hepatitis C)
Major Interactions
- Strong CYP3A4 inducers (e.g., Rifampin, Carbamazepine, Phenytoin, Phenobarbital, 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.
- Tranexamic acid - increased risk of thrombosis.
- Lamotrigine - decreased lamotrigine levels, potentially leading to loss of seizure control.
Moderate Interactions
- Moderate CYP3A4 inducers (e.g., Bosentan, Felbamate)
- CYP3A4 inhibitors (e.g., Itraconazole, Ketoconazole, Voriconazole, Grapefruit juice) - may increase estrogen/progestin levels, potentially increasing adverse effects.
- Thyroid hormones (e.g., Levothyroxine) - may increase thyroid-binding globulin, requiring increased thyroid hormone dose.
- Cyclosporine - increased cyclosporine levels, leading to potential 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, liver disease), and establish baseline health status.
Timing: Prior to initiation of therapy
Rationale: To identify pre-existing hypertension, which is a contraindication or risk factor for cardiovascular events.
Timing: Prior to initiation of therapy
Routine Monitoring
Frequency: Annually or more frequently if clinically indicated
Target: <140/90 mmHg
Action Threshold: Sustained elevation (e.g., >140/90 mmHg) may require discontinuation or change in contraceptive method.
Frequency: Annually
Target: Normal findings
Action Threshold: Abnormal findings require further investigation.
Frequency: Ongoing, patient education for self-monitoring
Target: Absence of symptoms
Action Threshold: Presence of symptoms (e.g., severe leg pain, chest pain, sudden vision changes, jaundice, severe headache) requires immediate medical evaluation.
Symptom Monitoring
- Severe abdominal pain (A)
- Chest pain, shortness of breath, or coughing up blood (C)
- Severe headaches, dizziness, weakness, or numbness (H)
- Eye problems (vision loss or blurring) (E)
- Severe leg pain in the calf or thigh (S)
- Jaundice (yellowing of skin or eyes)
- Mood changes, depression

Special Patient Groups
Pregnancy
Contraindicated during pregnancy. There is no indication for COC use in pregnancy, and there is no evidence of increased risk of birth defects in women who have inadvertently used COCs during early pregnancy.
Trimester-Specific Risks:
Lactation
Not recommended during lactation. Estrogens can decrease the quantity and quality of breast milk. Small amounts of contraceptive steroids and/or metabolites are excreted into breast milk, which may affect the infant.
Pediatric Use
Safety and efficacy are established for post-menarcheal females. Use before menarche is not indicated.
Geriatric Use
Not indicated for use in post-menopausal women. Safety and efficacy have not been established in geriatric populations.
Clinical Information
Clinical Pearls
- Adherence is key: Emphasize taking the pill at the same time every day to maintain consistent hormone levels and maximize efficacy.
- Missed pills: Provide clear, concise instructions for missed pills, stressing the need for backup contraception if multiple pills are missed.
- Smoking cessation: Strongly advise women over 35 who smoke to quit or choose an alternative contraceptive method due to significantly increased cardiovascular risks.
- Drug interactions: Counsel patients about potential interactions with other medications, especially antibiotics (though evidence for efficacy reduction is weak for most), anticonvulsants, and St. John's Wort.
- No STI protection: Reinforce that oral contraceptives do not protect against sexually transmitted infections.
- Postpartum use: Advise waiting at least 3-4 weeks postpartum before initiating COCs due to increased VTE risk, longer if breastfeeding.
- ACHES mnemonic: Educate patients on the warning signs of serious adverse events (Abdominal pain, Chest pain, Headaches, Eye problems, Severe leg pain).
