Aygestin (norethindrone) is a prescription progestin medication used to treat a variety of gynecological and hormonal conditions. As a synthetic form of the natural hormone progesterone, it provides targeted hormonal regulation, making it a cornerstone in managing disorders such as abnormal uterine bleeding, endometriosis, and secondary amenorrhea. Its well-established efficacy and predictable pharmacokinetic profile have made it a trusted option for clinicians specializing in reproductive endocrinology and women’s health. This product card offers a comprehensive overview of Aygestin, including its mechanism, benefits, and essential safety information.

Common use
Aygestin is commonly prescribed for the treatment of abnormal uterine bleeding caused by hormonal imbalance. It is also indicated for the management of endometriosis—a condition where tissue similar to the uterine lining grows outside the uterus, causing pain and infertility. Additionally, it is used to treat secondary amenorrhea (absence of menstrual periods in women who previously had regular cycles) and is sometimes part of hormone replacement regimens. Off-label uses may include contraception and management of premenstrual dysphoric disorder (PMDD), though these are not primary FDA-approved indications.
Dosage and direction
Dosage of Aygestin must be individualized based on the condition being treated and patient response. For abnormal uterine bleeding, the typical dose is 2.5 to 10 mg daily for 5 to 10 days during the second half of the menstrual cycle. For endometriosis, a starting dose of 5 mg daily for two weeks may be increased incrementally up to 15 mg daily. For amenorrhea, 2.5 to 10 mg is administered daily for 5 to 10 days. Tablets should be taken at the same time each day, with or without food. Always follow the specific instructions provided by the prescribing healthcare provider.
Precautions
Before using Aygestin, patients should disclose their full medical history, especially related to liver disease, kidney disease, depression, migraines, asthma, diabetes, epilepsy, or heart conditions. Regular monitoring of blood pressure, blood glucose, and liver function may be recommended. Use with caution in patients with risk factors for thromboembolic events. Avoid use during pregnancy unless clearly indicated and supervised. Smoking increases the risk of serious cardiovascular side effects, especially in women over 35.
Contraindications
Aygestin is contraindicated in patients with known hypersensitivity to norethindrone or any component of the formulation. It should not be used in individuals with current or history of thrombophlebitis or thromboembolic disorders, undiagnosed abnormal genital bleeding, known or suspected pregnancy, missed abortion, known or suspected hormone-dependent neoplasia (such as breast or endometrial cancer), or severe liver dysfunction or disease.
Possible side effect
Common side effects may include nausea, headache, dizziness, breast tenderness, bloating, mood changes, and irregular bleeding. Less frequently, patients may experience weight changes, acne, fatigue, or changes in libido. Serious side effects, though rare, can include symptoms of blood clots (sudden vision loss, chest pain, shortness of breath), severe depression, jaundice, or allergic reactions. Patients should contact their healthcare provider if any severe or persistent adverse effects occur.
Drug interaction
Aygestin may interact with several medications, including but not limited to: barbiturates, carbamazepine, phenytoin, rifampin, St. John’s wort, and certain HIV medications, which can decrease its effectiveness. Conversely, Aygestin may alter the levels or effects of warfarin, insulin, oral hypoglycemics, and certain immunosuppressants. Always inform your healthcare provider of all prescription, over-the-counter, and herbal products you are taking.
Missed dose
If a dose is missed, it should be taken as soon as remembered unless it is almost time for the next dose. In that case, skip the missed dose and resume the regular schedule. Do not double the dose to catch up. Consistently missing doses may reduce effectiveness and cause breakthrough bleeding. Consult your healthcare provider for specific guidance based on your treatment regimen.
Overdose
There have been no reports of serious ill effects from overdose of norethindrone. Symptoms may include nausea, vomiting, and drowsiness. In case of suspected overdose, seek medical attention or contact a poison control center immediately. Treatment is generally supportive and symptomatic.
Storage
Store Aygestin tablets at room temperature (20°–25°C or 68°–77°F), in a tightly closed container, away from light, moisture, and heat. Keep out of reach of children and pets. Do not use after the expiration date printed on the packaging.

Reviews
Clinical studies and patient reports generally reflect Aygestin’s efficacy in managing hormonal disorders, particularly abnormal uterine bleeding and endometriosis. Many users note significant symptom relief with appropriate dosing. Some report side effects such as mood swings or breakthrough bleeding, which often subside with continued use or dosage adjustment. Overall, it is regarded as a reliable and effective progestin therapy when used under medical supervision.
