For Healthcare Professionals
Applies to estropipate: oral tablet
Cases of oral pigmentation and ischemic colitis have been reported rarely.[Ref]
Use of unopposed estrogen therapy has been associated with an increased risk of endometrial cancer in patients with an intact uterus and less persuasively, with an increased risk of breast cancer.[Ref]
Endocrine side effects with estrogen use may result in increased levels of thyroxin-binding globulin, leading to an increase in total thyroid serum levels and a decrease in resin uptake of T3. Free thyroid hormone levels remain unchanged. Other endocrine effects include decreased fasting plasma glucose.[Ref]
Rare cases of focal nodular hyperplasia, liver cell adenomas, hepatic hemangiomas and well-differentiated hepatocellular carcinomas have been reported in association with estrogen therapy. Aggravation of porphyria has been reported.[Ref]
Hypercoagulability has been reported in women taking estrogens, although the clinical significance of such hypercoagulability in postmenopausal women taking estrogens has not been determined.[Ref]
Hypersensitivity reactions including anaphylaxis have been reported in association with estrogens and the dyes contained in some conjugated estrogen formulations.[Ref]
Nervous system side effects include migraine, dizziness, and mental depression.[Ref]
Dermatologic effects include chloasma or melasma, which may not resolve following discontinuation of estrogen therapy. Scalp hair loss, hirsutism, erythema nodosum, and hemorrhagic eruptions have occurred.[Ref]
