Mifepristone Drug Card - Nursing Medication Guide

Mifepristone is a medication primarily used for medical termination of intrauterine pregnancy up to 10 weeks gestation. It is often used in combination with another medication, misoprostol, to increase effectiveness. Understanding mifepristone is crucial for nursing students as it involves critical nursing assessments and patient education, especially in reproductive health settings. Additionally, mifepristone may be used in the management of high blood sugar in patients with Cushing's syndrome, making it a versatile drug that nurses must be familiar with for the NCLEX exam.

Mifepristone is classified as a progesterone receptor antagonist. It works by blocking the action of progesterone, a hormone necessary for pregnancy continuation. By inhibiting progesterone, mifepristone causes the uterine lining to shed, leading to detachment of the pregnancy. This mechanism is vital in its use for medical abortion. Additionally, in Cushing's syndrome, mifepristone blocks cortisol receptors, helping to manage hyperglycemia associated with the condition.

Mifepristone is primarily indicated for the medical termination of intrauterine pregnancies up to 10 weeks. It is used in conjunction with misoprostol to increase efficacy. Another indication is for the control of hyperglycemia secondary to hypercortisolism in adult patients with endogenous Cushing's syndrome who have type 2 diabetes mellitus or glucose intolerance and who failed surgery or are not candidates for surgery.

Before administering mifepristone, confirm the gestational age through ultrasound to ensure it is within the eligible timeframe for use. Obtain a thorough medical history, including any contraindications such as chronic adrenal failure or ectopic pregnancy. During therapy, monitor for signs of excessive bleeding, cramping, and ensure follow-up appointments are scheduled to confirm complete termination. Educate patients on the importance of adherence to the medication regimen and report any severe adverse effects immediately.

Common side effects of mifepristone include nausea, vomiting, diarrhea, and heavy bleeding. Serious adverse reactions can include severe cramping, excessive bleeding requiring transfusion, and infection. Nurses must be vigilant in monitoring these side effects, especially in outpatient settings, and provide appropriate interventions or referrals if severe symptoms occur.

Educate patients on the expected side effects and the importance of taking the medication as prescribed. Inform them about the possibility of heavy bleeding and when to seek medical help. Stress the importance of follow-up visits to confirm complete termination of pregnancy. In cases of Cushing's syndrome, advise patients on the need for regular blood glucose monitoring and the signs of adrenal insufficiency.

Mifepristone may appear on the NCLEX in questions regarding its use for medical abortion and management of Cushing’s syndrome. Key points include its mechanism of action, the importance of confirming gestational age, and monitoring for severe side effects. Remember to focus on patient education and follow-up care as critical elements of patient management.
