Ethinylestradiol + Lynestrenol
When using the combination of Ethinylestradiol and Lynestrenol, several important precautions need to be considered:
- Pregnancy and breastfeeding: This combination is contraindicated during pregnancy as it can harm fetal development. If a woman becomes pregnant while using this combination, she should discontinue use immediately and seek medical advice. Additionally, during breastfeeding, this combination may be excreted into breast milk and can affect milk production or the infant’s health. Alternative contraceptive methods are recommended for breastfeeding mothers.
- Thromboembolic risks: Both Ethinylestradiol (a synthetic estrogen) and Lynestrenol (a synthetic progestin) can increase the risk of thromboembolic events, such as deep vein thrombosis (DVT), pulmonary embolism (PE), and stroke, particularly in women with pre-existing risk factors such as obesity, smoking, hypertension, or a history of thrombosis. Caution is advised in women with these conditions, and regular monitoring for signs of thrombosis should be performed.
- Liver function: This combination should be used with caution in patients with liver disease or a history of liver dysfunction. Estrogen-containing contraceptives can affect liver function, potentially exacerbating conditions like jaundice or liver tumors. Liver function tests should be monitored periodically.
- Cardiovascular health: Women with high blood pressure, elevated cholesterol, or a history of cardiovascular disease should use this combination with caution, as the estrogen component (Ethinylestradiol) may increase the risk of adverse cardiovascular events.
- Breast cancer: The use of estrogen-containing contraceptives may be contraindicated in women with a history of breast cancer or other estrogen-sensitive cancers, as it can stimulate the growth of hormone-sensitive tumors.
- Smoking: Women over 35 who smoke heavily (more than 15 cigarettes per day) are at increased risk of serious cardiovascular events (e.g., heart attack, stroke) when using estrogen-containing contraceptives. This combination should generally be avoided in such individuals.
The primary indications for the combination of Ethinylestradiol and Lynestrenol include:
1. Contraception: This combination is mainly used for oral contraception. Ethinylestradiol (synthetic estrogen) and Lynestrenol (synthetic progestin) work together to prevent ovulation, alter cervical mucus to block sperm entry, and modify the endometrial lining to prevent implantation of a fertilized egg. It is a highly effective method of preventing pregnancy when taken as directed.
2. Regulation of menstrual cycles: In addition to contraception, this combination is sometimes prescribed to regulate menstrual cycles, reduce heavy menstrual bleeding, and alleviate dysmenorrhea (painful periods). The hormonal balance it provides helps in establishing more predictable and manageable cycles.
3. Management of endometriosis: This combination may be used as part of a treatment plan for women with endometriosis, a condition where tissue similar to the uterine lining grows outside the uterus. The hormones work by suppressing ovulation and reducing the growth of endometrial tissue, helping to alleviate pain and other symptoms.
4. Polycystic Ovary Syndrome (PCOS): For women with PCOS, this combination can be used to manage symptoms such as irregular menstruation and elevated androgen levels, which may cause issues like acne, excessive hair growth, or thinning hair. The hormones help regulate menstrual cycles and reduce androgenic symptoms.
This combination should not be used in the following cases:
- Pregnancy: As with most hormonal contraceptives, this combination is contraindicated during pregnancy as it can be harmful to the developing fetus.
- History of thromboembolic disorders: Women with a history of deep vein thrombosis (DVT), pulmonary embolism (PE), or stroke should not use this combination due to the increased risk of blood clots associated with estrogen and progestin.
- Liver diseases: Patients with active liver disease (e.g., cirrhosis, hepatitis, liver tumors) should avoid this combination as it can exacerbate liver dysfunction.
- Estrogen-dependent cancers: This combination is contraindicated in women with a history of breast cancer, ovarian cancer, or other estrogen-sensitive cancers, as it can stimulate the growth of hormone-sensitive tumors.
- Severe hypertension: Women with uncontrolled high blood pressure or significant cardiovascular conditions should not use this combination, as it may worsen their condition.
- Smokers over 35: Women who are over 35 years old and smoke heavily are at an increased risk of cardiovascular events when using estrogen-containing contraceptives. This combination should generally be avoided in such individuals.
Common side effects of Ethinylestradiol and Lynestrenol include:
- Hormonal side effects: These include nausea, headaches, breast tenderness, mood changes, and weight gain. These symptoms are often most noticeable in the early stages of use and may subside after a few months.
- Breakthrough bleeding: Some women may experience light bleeding or spotting between periods, especially during the first few months of use. This is often temporary and resolves over time.
- Acne and skin changes: Hormonal fluctuations can lead to changes in skin condition, including acne. While some women experience improvement, others may see worsening of skin issues.
- Thromboembolic risks: Although rare, both estrogen and progestin increase the risk of blood clots, which could lead to deep vein thrombosis, pulmonary embolism, or stroke. Women with risk factors such as obesity, smoking, or hypertension should be closely monitored for these risks.
- Liver issues: Rarely, hormonal contraceptives like this combination may cause liver dysfunction, including jaundice, benign liver tumors, or gallbladder disease. Monitoring liver function is advisable for women with a history of liver disease.
- Mood and libido changes: Some women report changes in mood, libido, or mental health, including depression or irritability. These symptoms should be evaluated if they persist or worsen.

The combination of Ethinylestradiol and Lynestrenol works primarily by altering the hormonal environment in several ways:
- Ethinylestradiol: As a synthetic estrogen, Ethinylestradiol prevents ovulation by inhibiting the release of gonadotropins (FSH and LH) from the pituitary gland. It also alters the endometrial lining to make it less receptive to implantation, and it thickens cervical mucus, which prevents sperm from entering the uterus.
- Lynestrenol: A synthetic progestin, Lynestrenol also inhibits ovulation by suppressing the secretion of LH and FSH. Additionally, it thickens cervical mucus and modifies the endometrial lining to prevent implantation. It helps to reduce breakthrough bleeding and further contributes to the contraceptive effect of the combination.
- Combined effect: Together, these two hormones provide a highly effective contraceptive effect by preventing ovulation, thickening cervical mucus, and creating an unfavorable environment for implantation. This combination also helps regulate menstrual cycles and manage conditions like endometriosis and PCOS.
Several interactions are important to consider when using Ethinylestradiol and Lynestrenol:
- CYP450 enzyme inducers: Medications that induce the cytochrome P450 enzyme system, such as rifampin, carbamazepine, phenytoin, and barbiturates, can reduce the effectiveness of this contraceptive combination. Women using these drugs should consider additional non-hormonal contraceptive methods.
- Antibiotics: While most antibiotics do not affect the efficacy of Ethinylestradiol and Lynestrenol, antibiotics like rifampin may reduce their effectiveness. If antibiotics are prescribed, additional contraceptive measures should be taken to ensure effectiveness.
- Antifungal agents: Antifungal drugs like ketoconazole may affect the metabolism of Ethinylestradiol and Lynestrenol, potentially altering blood levels of the hormones. Dose adjustments and monitoring may be needed.
- Gastrointestinal medications: Drugs that affect gastrointestinal motility (e.g., those used to treat diarrhea) can reduce the absorption of oral contraceptives. It is important to monitor for any signs of contraceptive failure when these drugs are used.
- Alcohol: Excessive alcohol intake does not directly affect the pharmacokinetics of the combination, but it may increase the likelihood of missed doses or improper use of the contraceptive. This may increase the risk of pregnancy.
The typical dosage regimen for Ethinylestradiol and Lynestrenol involves:
- Standard dose: One tablet is taken daily for 21 consecutive days, followed by a 7-day pill-free interval during which withdrawal bleeding occurs. Some regimens may include taking the active tablets continuously without a break.
- Missed dose: If a dose is missed, the user should follow the specific instructions provided with the product. Generally, missed doses should be taken as soon as possible, and additional contraceptive methods may be required for a short time.
This combination is not recommended for use in children and is typically prescribed to adult women, especially for contraception or menstrual regulation. The use in adolescents should be carefully considered based on individual needs and discussed with a healthcare provider.
No specific dose adjustment is required for patients with renal impairment when using Ethinylestradiol and Lynestrenol, as these drugs are metabolized by the liver. However, women with significant renal dysfunction should be monitored for any potential changes in drug metabolism and other complications.
