Final answer:
Progestin-only pills are recommended for women with contraindications to estrogen such as a history of blood clots or cardiovascular risk factors, history of breast cancer, migraines with aura, or liver disease. These pills do not increase the risk of blood clots and work by thickening cervical mucus and sometimes inhibiting ovulation.
Step-by-step explanation:
Progestin-Only Pills and Contraindications for Combined Oral Contraceptives
Progestin-only pills, also known as the mini-pill, should be given to women who have contraindications to estrogen. These include women who have:
- A history of estrogen-related thromboembolic events (e.g., deep vein thrombosis or pulmonary embolism)
- Risk factors for cardiovascular disease, such as uncontrolled hypertension or smoking over the age of 35
- A history of or current breast cancer
- Migraines with aura, which are associated with an increased risk of stroke when taking estrogen
- Liver disease, which can be affected by the metabolism of estrogen
Because progestin-only pills do not contain estrogen, they do not increase the risk of blood clots and may be safer for women with the aforementioned conditions. These pills primarily work by thickening cervical mucus to prevent sperm from reaching an egg and by inhibiting ovulation in some women. It's important to note that while they are quite effective, they must be taken at the same time every day to maintain their efficacy.
Women considering hormonal contraception should consult with a healthcare provider to discuss the most suitable options based on their individual medical history and risk factors.
