Overdose Symptoms:
- Nausea
- Vomiting
- Withdrawal bleeding (in females)
- For iron overdose (from ferrous fumarate): abdominal pain, diarrhea, vomiting (possibly bloody), lethargy, pallor, cyanosis, shock, metabolic acidosis, liver damage.
What to Do:
Seek immediate medical attention. For iron overdose, call a poison control center (1-800-222-1222) or emergency services. Treatment may involve gastric lavage, chelation therapy (e.g., deferoxamine), and supportive care.
Drug Interactions
Contraindicated Interactions
- Ombitasvir/Paritaprevir/Ritonavir, Dasabuvir (used for Hepatitis C): May increase ALT levels significantly.
- Tranexamic acid: Increased risk of thrombosis.
Major Interactions
- CYP3A4 inducers (e.g., Carbamazepine, Phenytoin, Rifampin, Barbiturates, Topiramate, Griseofulvin, St. John's Wort): May decrease contraceptive efficacy and increase breakthrough bleeding.
- Lamotrigine: COCs may decrease lamotrigine plasma concentrations, potentially leading to loss of seizure control.
- Certain antibiotics (e.g., Rifampin): May reduce efficacy. While less evidence for broad-spectrum antibiotics, caution is advised.
- Bosentan: May decrease contraceptive efficacy.
Moderate Interactions
- Ascorbic acid (Vitamin C): May increase ethinyl estradiol levels.
- Acetaminophen: May increase ethinyl estradiol levels.
- Atorvastatin: May increase ethinyl estradiol levels.
- Thyroid hormones (e.g., Levothyroxine): COCs may increase thyroid-binding globulin, leading to increased thyroid hormone requirements.
- Warfarin and other anticoagulants: COCs may affect anticoagulant response; monitor INR/PT.
- Theophylline: COCs may increase theophylline levels.
- Cyclosporine: COCs may increase cyclosporine levels.
Minor Interactions
- Not typically listed as minor for COCs, as most interactions are significant due to efficacy or safety concerns.

Special Patient Groups
Pregnancy
Contraindicated. Blisovi FE 1/20 should not be used during pregnancy. If pregnancy occurs while taking this medication, discontinue use immediately.
Trimester-Specific Risks:
Lactation
Not recommended. Estrogens and progestins can decrease the quantity and quality of breast milk and are excreted in breast milk. Consider progestin-only methods or non-hormonal contraception if breastfeeding.
Pediatric Use
Indicated for contraception in post-menarcheal females. Safety and efficacy are expected to be similar to adults. Not indicated before menarche.
Geriatric Use
Not indicated for post-menopausal women. This medication is for contraception and is not used in the geriatric population.
Clinical Information
Clinical Pearls
- Consistent daily use at the same time is crucial for contraceptive efficacy. Missing pills, especially active ones, increases the risk of pregnancy.
- Breakthrough bleeding or spotting is common, especially during the first few cycles, and usually resolves. If persistent or heavy, consult a healthcare provider.
- Non-contraceptive benefits include regulation of menstrual cycles, reduction of menstrual pain and blood loss, and potential reduction in risk of ovarian and endometrial cancers.
- The ferrous fumarate tablets are for iron supplementation during the placebo week and do not contribute to contraception.
- Always advise patients to use a backup method of contraception (e.g., condoms) for the first 7 days of the first pack, or after missing multiple pills, or when taking interacting medications.
Alternative Therapies
- Progestin-only pills (mini-pill)
- Contraceptive patch (e.g., Xulane)
- Vaginal ring (e.g., NuvaRing, Annovera)
- Contraceptive implant (e.g., Nexplanon)
- Intrauterine devices (IUDs) (hormonal or non-hormonal)
- Contraceptive injection (e.g., Depo-Provera)
- Barrier methods (condoms, diaphragm, cervical cap)
- Spermicides
- Surgical sterilization (tubal ligation, vasectomy)
