Overview

â„šī¸

What is this medicine?

Vyfemla is a birth control pill that contains two female hormones, an estrogen (ethinyl estradiol) and a progestin (norethindrone). It works by preventing ovulation (the release of an egg from the ovary) and by changing the cervical mucus and uterine lining to prevent pregnancy. It is taken daily to prevent pregnancy.

How to Use This Medicine

Taking Your Medication Correctly

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.

Pharmacology

đŸ”Ŧ

Mechanism of Action

Combined oral contraceptives (COCs) like Vyfemla primarily work by suppressing gonadotropins (luteinizing hormone and follicle-stimulating hormone), which in turn inhibits ovulation. They also cause changes in the cervical mucus, making it more viscous and less permeable to sperm, and alter the endometrium, making it less receptive to implantation.
📊

DurationOfAction: Daily dosing is required to maintain contraceptive efficacy.

Safety & Warnings

âš ī¸

BLACK BOX WARNING

Cigarette smoking increases the risk of serious cardiovascular events from combined oral contraceptive (COC) use. This risk increases with age, particularly in women over 35 years of age, and with the number of cigarettes smoked. For this reason, COCs, including Vyfemla, are contraindicated in women who are over 35 years of age and smoke.

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

Blood pressure

Rationale: To identify pre-existing hypertension, which is a contraindication or risk factor for cardiovascular events.

Timing: Prior to initiation of therapy

📊

Routine Monitoring

Blood pressure

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.

Annual physical examination (including breast exam, pelvic exam, Pap test as per guidelines)

Frequency: Annually

Target: Normal findings

Action Threshold: Abnormal findings require further investigation.

Symptoms of venous thromboembolism (VTE), arterial thromboembolism (ATE), liver dysfunction, depression

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.

đŸ‘ī¸

Symptom Monitoring

  • Severe abdominal pain (A)
  • Chest pain, shortness of breath, or coughing up blood (C)

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:

First Trimester: No increased risk of birth defects reported from inadvertent exposure.
Second Trimester: Not applicable, as use is contraindicated.
Third Trimester: Not applicable, as use is contraindicated.
🤱

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.

Infant Risk: Potential for decreased milk supply and potential for adverse effects on the infant (e.g., jaundice, breast enlargement). Consider non-hormonal methods or progestin-only methods if contraception is needed during breastfeeding.
đŸ‘ļ

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).
🔄

Alternative Therapies

  • Progestin-only pills (mini-pill)
  • Progestin injection (Depo-Provera)
