Comprehensive Reproductive System Medication Table and Nursing Guide
Estrogen-Progestin Combinations
Exemplar Drugs:
estradiolandnorethindrone.Mechanism of Action: These drugs function by preventing ovulation. This is achieved by activating a negative feedback loop on the release of Follicle-Stimulating Hormone (
FSH) and Luteinizing Hormone (LH).Side Effects and Adverse Reactions: - Weight gain. - Migraines. - Increased risk of breast cancer. - Thromboembolism (blood clots). - Acne. - Hirsutism (excessive body hair).
Black Box Warning: The use of hormonal contraceptives containing estrogen carries a significant warning regarding cigarette smoking. Smoking increases the risk of serious cardiovascular adverse effects. This risk is notably higher in women who are over the age of
and in those who are heavy smokers, defined as smoking more thancigarettes per day.Nursing Actions and Clinical Considerations: - The medication must be taken at the same time each day to maintain efficacy. - Contraindicated in clients who experience migraines with aura. - Contraindicated in clients with a history of breast cancer. - Healthcare providers must teach patients to recognize the signs and symptoms of clotting. - Patients must be educated that smoking greatly increases their cardiovascular risks.
Desired Outcome: Successful contraception.
Progestin-Only Drugs
Exemplar Drug:
norethindrone.Mechanism of Action: This medication works through two primary mechanisms: - It thickens the cervical mucus to create a physical block against sperm. - It alters the endometrial lining, which serves to reduce the likelihood of implantation.
Side Effects and Adverse Reactions: - Increased appetite often leading to weight gain. - Fatigue. - Acne. - Hirsutism.
Nursing Actions and Clinical Considerations: - These drugs are generally considered less effective than Combined Oral Contraceptives (COCs). - Patients often experience more irregular bleeding patterns compared to combination drugs.
Desired Outcome: Successful contraception.
Estrogen and Estrogen-Progestin Combinations (Hormone Replacement)
Exemplar Drug:
conjugated estrogens.Mechanism of Action: This therapy replaces multiple forms of estrogen within the body to support and restore hormone balance.
Side Effects and Adverse Reactions: - Black Box Warning (Endometrial Cancer): Estrogens are associated with a higher risk of endometrial cancer in postmenopausal women. - Black Box Warning (Breast Cancer): When
conjugated estrogensare used in combination withmedroxyprogesterone, the risk of breast cancer is increased. - Black Box Warning (Cardiovascular and Neurological): When used alone, estrogens increase the risks of stroke, Deep Vein Thrombosis (DVT), Myocardial Infarction (MI), pulmonary emboli (PE), and dementia.Nursing Actions and Clinical Considerations: - Avoid use in clients with a known risk for clotting. - Educate patients specifically on the warning signs of cardiovascular events (stroke,
DVT, etc.). - Be aware that these medications may increase the risk of dementia in older adults. - The medication is available in multiple delivery forms.Desired Outcome: Reduction of menopausal symptoms.
Progestins (Therapeutic and Contraceptive)
Exemplar Drug:
medroxyprogesterone.Mechanism of Action: This drug suppresses the effects of estrogen on the uterus and restores hormone balance in some reproductive disorders.
Side Effects and Adverse Reactions: - Breast tenderness. - Spotting (irregular bleeding). - Weight gain. - Black Box Warning: When progestins are combined with
conjugated estrogens, there is an increased risk of stroke,DVT,MI, pulmonary emboli, and invasive breast cancer. - Neurological Risk: Women agedor older have an increased risk of dementia when treated with progestins. - Bone Health: Women receiving the injectable form ofmedroxyprogesteroneare at a significant risk for the loss of bone mineral density.Nursing Actions and Clinical Considerations: - Patients should be taught to increase their calcium intake to mitigate bone density loss. - Indicated for the treatment of Dysfunctional Uterine Bleeding (
DUB), endometriosis, and for use as contraception.Desired Outcome: Treatment of
DUB, management of endometriosis, or successful contraception.
Androgen Therapy
Exemplar Drug:
testosterone.Mechanism of Action: Replaces deficient levels of natural testosterone and supports the development and maintenance of male secondary sex characteristics.
Side Effects and Adverse Reactions: - Edema (fluid retention). - Acne. - Increased levels of Low-Density Lipoprotein (
LDL). - Feminization: Excess testosterone can be metabolized into estrogen; consequently, men taking high doses may experience feminization symptoms.Nursing Actions and Clinical Considerations: - Absolute Contraindication: This medication is strictly prohibited in men with breast cancer or prostate cancer (
Ca). - Patients must be taught the proper application technique for topical versions to avoid secondary exposure to others. - Nurses must monitor laboratory results including Prostate-Specific Antigen (PSA), Complete Blood Count (CBC), Comprehensive Metabolic Panel (CMP), and lipid profiles.Desired Outcome: Normalization of testosterone levels.
Phosphodiesterase-5 (PDE-5) Inhibitors
Exemplar Drug:
sildenafil.Mechanism of Action: This drug relaxes smooth muscle and increases blood flow specifically to the penis.
Side Effects and Adverse Reactions: - Priapism (prolonged erection). - Hypotension (severely low blood pressure), especially when combined with nitrates. - Myocardial Infarction (
MI). - Sudden death.Nursing Actions and Clinical Considerations: - Under no circumstances should this drug be used with nitrates. - The nurse must assess the patient’s cardiovascular status before administration. - Patient teaching: Take the medication approximately
hour before sexual activity. - Patient teaching: Report any erections lasting longer thanhours to a healthcare provider immediately.Desired Outcome: Successful sexual activity and reduction of Erectile Dysfunction (
ED) symptoms.
5-Alpha Reductase Inhibitors
Exemplar Drug:
finasteride.Mechanism of Action: This medication inhibits the conversion of testosterone into Dihydrotestosterone (
DHT), which results in a reduction of prostate size.Side Effects and Adverse Reactions: - Sexual dysfunction. - Teratogenic effects on the male fetus.
Nursing Actions and Clinical Considerations: - Occupational Hazard: Pregnant nurses (or those who may become pregnant) must avoid handling this medication because it can be absorbed through the skin and cause harm to a male fetus. - Blood Donation: Patients who take
finasterideare prohibited from donating blood while on drug therapy.Desired Outcome: Reduced prostate size.
