Gynovin (Ethinylestradiol, Gestodene)

Gynovin is indicated for women who seek a reliable, reversible method of preventing pregnancy.

• Prevention of pregnancy when taken as a combined oral contraceptive.
• Regulation of menstrual cycle and reduction of dysmenorrhea.
• Management of acne associated with hormonal fluctuations.
• Decrease in the risk of ovarian cyst formation.
• May be used to control heavy menstrual bleeding under medical supervision.

Like all hormonal contraceptives, Gynovin may cause side effects; most are mild and transient.

Common

• Nausea or mild stomach upset.
• Headache or migraine‑like pain.
• Breast tenderness or enlargement.
• Spotting or breakthrough bleeding between periods.
• Mood changes or mild depression.
• Decreased libido.

Serious

• Blood clots in veins or lungs (deep vein thrombosis, pulmonary embolism).
• Stroke or transient ischemic attack.
• Severe hypertension or hypertensive crisis.
• Liver dysfunction or jaundice.
• Allergic reactions such as rash, swelling, or anaphylaxis.

Before prescribing Gynovin, clinicians should evaluate individual risk factors and counsel patients on safety considerations.

• History of thromboembolic disorders, stroke, or myocardial infarction.
• Smoking, especially in women over 35 years of age.
• Uncontrolled hypertension or diabetes with vascular complications.
• Current or past breast, liver, or estrogen‑dependent cancers.
• Liver disease that impairs hormone metabolism.
• Use of certain anticonvulsants or antibiotics that reduce contraceptive efficacy.
• Pregnancy or breastfeeding status should be confirmed before initiation.

Gynovin can interact with other medicines, affecting its effectiveness or increasing health risks.

Avoid

• Combined hormonal contraceptives with other estrogen‑containing products (e.g., hormone replacement therapy).
• Strong CYP3A4 inducers such as rifampin, carbamazepine, phenytoin, or St. John’s wort.
• Certain antiviral agents (e.g., protease inhibitors) that may alter hormone levels.
• Selective serotonin reuptake inhibitors (SSRIs) that may affect platelet function.

Use with caution

• Antifungal azoles (ketoconazole, itraconazole) that can increase hormone concentrations.
• Some antibiotics (e.g., tetracycline, metronidazole) that may affect gut flora.
• Herbal supplements like ginseng that could modify metabolism.
• Medications that increase blood pressure (e.g., decongestants) requiring monitoring.
• Anticoagulants (warfarin) may have altered effect; monitor INR.
