Background and Date of Approval

Mifepristone is a medication that plays a vital role in reproductive health. Originally developed in the 1980s, it was approved by the U.S. Food and Drug Administration (FDA) in September 2000. It is best known for its use in combination with another medicine to end an early pregnancy. However, it is also approved for treating specific medical conditions such as Cushing’s syndrome. Over the years, several clinical trials have confirmed its safety and effectiveness, especially when used under proper medical supervision. The medicine works by blocking the action of certain hormones in the body, helping control various hormonal disorders.

Mechanism of Action of undefined

Mifepristone works by blocking a hormone called progesterone, which is essential for maintaining pregnancy. Without progesterone, the uterus can no longer support the pregnancy, and the process of ending the pregnancy begins. In conditions like Cushing’s syndrome, the medicine blocks cortisol receptors, helping to reduce the excessive effects of cortisol in the body. This dual action makes the drug helpful in both reproductive and hormonal disorders. It doesn't work on its own for pregnancy termination; it’s combined with another drug (misoprostol) to complete the process.

Uses of undefined

Mifepristone is approved for the following medical uses:

  • Medical termination of intrauterine pregnancy up to 10 weeks (used with misoprostol)
  • Management of high blood sugar (hyperglycemia) in adults with Cushing’s syndrome caused by overproduction of cortisol due to adrenal gland issues
  • Labour induction in cases of fetal death (under specific guidelines)

Always use only as prescribed by a healthcare provider.

undefined Drug administaration and Dosage available

This medicine is taken orally in tablet form. For medical termination of pregnancy, it is typically given as a single 200 mg tablet, followed by misoprostol after 24–48 hours. In the case of Cushing’s syndrome, the dosage may start at 300 mg once daily and can be adjusted based on patient response and tolerance. Dosage should always be individualised and supervised by a doctor.

Precautions

Before using this medicine, inform your doctor if you have bleeding disorders, anaemia, heart disease, or if you are on long-term corticosteroids. It's important to undergo ultrasound and blood tests before starting treatment to confirm pregnancy details and rule out complications like ectopic pregnancy. Patients with Cushing’s syndrome should be monitored regularly for changes in blood pressure, potassium levels, and adrenal function. Avoid grapefruit juice during treatment, as it can affect how the drug works.

Common side effects:

  • Nausea or vomiting

Word Of Advice

Always take this medication exactly as prescribed by your doctor. Do not self-administer or share it with anyone. If you're using it for pregnancy termination, follow up with your doctor after a week to confirm that the process is complete. In the case of Cushing’s syndrome, long-term use requires regular lab monitoring and dose adjustments. Avoid alcohol and heavy physical activity during the course of treatment. If you notice any unusual symptoms, reach out to your healthcare provider immediately.
