Precautions & Cautions
This medication may increase the risk of blood clots, stroke, or heart attack. Discuss this risk with your doctor. The hormone drospirenone in this medication may further increase the risk of blood clots compared to other birth control pills. Consult your doctor to understand this risk.
If you will be immobile for extended periods, such as during long trips, bedrest after surgery, or illness, inform your doctor, as this may 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.
If you are taking a salt substitute containing potassium, a potassium-sparing diuretic, or a potassium product, inform your doctor.
This medication may cause high blood pressure. Have your blood pressure checked regularly as advised by your doctor. It may also lead to high cholesterol and triglyceride levels. If you have high cholesterol or triglycerides, discuss this with your doctor. Regular blood tests are necessary; follow your doctor's instructions.
Regular breast exams, gynecology check-ups, and breast self-exams (as directed by your doctor) are crucial while taking this medication.
This medication may interfere with certain laboratory tests. Inform all your healthcare providers and laboratory personnel that you are taking this medication.
Prolonged sun exposure may cause dark skin patches on your face while taking this medication. Avoid sun, sunlamps, and tanning beds, and use sunscreen and protective clothing and eyewear.
Certain medications, herbal products, or health conditions may reduce the effectiveness of hormone-based birth control. Ensure your doctor is aware of all your medications and health issues, as you may need to use a non-hormone birth control method, such as condoms, in addition to this medication.
This medication does not protect against sexually transmitted diseases like HIV or hepatitis. Use latex or polyurethane condoms during sexual activity. If you have questions, consult your doctor.
The risk of cervical cancer may be higher in individuals taking hormone-based birth control, although this may be attributed to other factors. Discuss any concerns with your doctor.
Some studies suggest a potential increased risk of breast cancer associated with long-term use of hormone-based birth control, while others have not found this link. If you have questions, consult your doctor.
This medication is not intended for use in children who have not yet had their first menstrual period. If you suspect you are pregnant or have a positive pregnancy test, contact your doctor immediately.
Overdose Information
Overdose Symptoms:
- Nausea
- Vomiting
- Vaginal bleeding (withdrawal bleeding)
What to Do:
Seek medical attention. There is no specific antidote. Treatment is symptomatic and supportive. Call 1-800-222-1222 (Poison Control).
Drug Interactions
Contraindicated Interactions
- Hepatitis C drug combinations containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir (risk of ALT elevations)
- Strong CYP3A4 inhibitors (e.g., ketoconazole, itraconazole, voriconazole, clarithromycin, indinavir, nelfinavir, ritonavir, telithromycin) in patients with renal or adrenal insufficiency (due to increased drospirenone exposure and hyperkalemia risk)
Major Interactions
- Potassium-sparing diuretics (e.g., spironolactone, amiloride, triamterene), potassium supplements, ACE inhibitors, ARBs, NSAIDs, heparin (increased risk of hyperkalemia due to drospirenone's anti-mineralocorticoid activity)
- CYP3A4 inducers (e.g., carbamazepine, phenytoin, rifampin, barbiturates, topiramate, St. John's Wort) (decreased contraceptive efficacy and increased breakthrough bleeding)
- Lamotrigine (decreased lamotrigine levels, loss of seizure control)
- Thyroid hormone replacement therapy (increased thyroid binding globulin, requiring increased thyroid hormone dose)
- Corticosteroids (increased corticosteroid levels)
Moderate Interactions
- Grapefruit juice (may increase ethinyl estradiol levels)
- Ascorbic acid (may increase ethinyl estradiol levels)
- Atorvastatin (may increase ethinyl estradiol levels)
- Paracetamol (acetaminophen) (may increase ethinyl estradiol levels)
- Troleandomycin (increased risk of intrahepatic cholestasis)
- Cyclosporine (increased cyclosporine levels)
- Theophylline (increased theophylline levels)
- Voriconazole (may increase ethinyl estradiol levels)
Minor Interactions
- Not specifically categorized as minor for this drug, but general interactions with other drugs metabolized by CYP enzymes or affecting gut flora could occur.
Monitoring
Baseline Monitoring
Rationale: To identify pre-existing hypertension, which is a contraindication or risk factor for cardiovascular events.
Timing: Prior to initiation
Rationale: To assess for contraindications and risk factors for VTE, arterial thrombotic disease, liver disease, migraines, and estrogen-dependent neoplasms.
Timing: Prior to initiation
Rationale: To rule out contraindications and establish baseline health status.
Timing: Prior to initiation (as clinically indicated)
Rationale: To assess for baseline hyperkalemia, especially in patients with renal impairment or those on concomitant medications that may increase potassium.
Timing: Prior to initiation, particularly in at-risk patients
Routine Monitoring
Frequency: Annually or as clinically indicated
Target: <140/90 mmHg
Action Threshold: Sustained elevation >140/90 mmHg may require discontinuation or change in contraception.
Frequency: Periodically, especially during the first cycle, in patients at risk for hyperkalemia (e.g., concomitant medications, mild renal impairment)
Target: 3.5-5.0 mEq/L
Action Threshold: Levels >5.5 mEq/L require immediate evaluation and potential discontinuation.
Frequency: Annually
Target: N/A
Action Threshold: New risk factors or interacting medications may necessitate a change in contraception.
Symptom Monitoring
- Signs of venous thromboembolism (VTE): severe leg pain, chest pain, shortness of breath, sudden vision changes, sudden severe headache
- Signs of arterial thrombotic events: sudden numbness or weakness, severe headache, vision changes, speech difficulties
- Signs of liver problems: yellowing of skin/eyes (jaundice), dark urine, severe abdominal pain
- Signs of hyperkalemia: muscle weakness, fatigue, heart palpitations, numbness/tingling
- Changes in menstrual bleeding patterns (e.g., breakthrough bleeding, amenorrhea)
- Mood changes, depression
- Severe abdominal pain (possible ovarian cyst rupture or ectopic pregnancy)
Special Patient Groups
Pregnancy
Contraindicated in pregnancy. There is no indication for use in pregnancy, and there is evidence of fetal risk. Discontinue if pregnancy is confirmed.
Trimester-Specific Risks:
Lactation
Not recommended during breastfeeding. Estrogens can decrease the quantity and quality of breast milk and may be excreted in breast milk, potentially affecting the infant. Progestins are also excreted in breast milk.
Pediatric Use
Indicated for postmenarcheal females for contraception, PMDD, and moderate acne. Safety and efficacy are established for this population. Not for use in prepubertal girls.
Geriatric Use
Not indicated for use in postmenopausal women. Risk of cardiovascular events increases with age, and COCs are generally not used in women over 65.
Clinical Information
Clinical Pearls
- Drospirenone has anti-mineralocorticoid activity, which can lead to hyperkalemia, especially in patients with renal impairment or those taking other potassium-sparing drugs. Monitor potassium levels in at-risk patients.
- Counsel patients on the importance of consistent daily dosing to maintain contraceptive efficacy.
- Emphasize the black box warning regarding smoking and cardiovascular risk, especially for women over 35.
- Inform patients about potential for breakthrough bleeding, especially during the first few cycles, which usually resolves.
- Advise patients to use a backup method of contraception (e.g., condoms) if they miss pills, experience vomiting or severe diarrhea, or are taking interacting medications (e.g., antibiotics, anticonvulsants, St. John's Wort).
- This formulation (3mg drospirenone/0.02mg ethinyl estradiol) is also approved for the treatment of moderate acne and premenstrual dysphoric disorder (PMDD).
Alternative Therapies
- Progestin-only pills (mini-pill)
- Progestin injection (e.g., Depo-Provera)
- Progestin implant (e.g., Nexplanon)
- Intrauterine devices (IUDs - hormonal and non-hormonal)
- Barrier methods (condoms, diaphragm, cervical cap)
- Spermicides
- Natural family planning methods
- Sterilization (tubal ligation, vasectomy)
- For acne: topical retinoids, oral antibiotics, spironolactone, isotretinoin
- For PMDD: SSRIs, lifestyle modifications
