Drug Precautions ::

 Precautions

Pregnancy: Category X. Lactation: Excreted in breast milk. Children: Safety and efficacy not established. Calcium and phosphorus metabolism: Use drug with caution in patients with metabolic bone diseases. Fluid retention: Use drug with careful observation when conditions that might be affected by this factor are present (eg, asthma, cardiac or renal dysfunction, epilepsy). Gallbladder disease: Risk of gallbladder disease may increase in women receiving postmenopausal estrogens. Hepatic impairment: Metabolism may be impaired; use drug with caution. Induction of malignant neoplasms: May increase risk of endometrial or other carcinomas. Familial hyperlipoproteinemia: May be associated with massive elevations of plasma triglycerides. Uterine leiomyomata: Preexisting uterine leiomyomata may increase in size during estrogen use. Tartrazine sensitivity: Some products contain tartrazine, which may cause allergic reaction in susceptible patients. Unopposed estrogen administration (eg, without progesterone): Increases risk of uterine cancer. Therefore, when using estrogens on long-term basis in a woman with intact uterus, consider cyclic therapy with progesterone (eg, estrogen on days 1 to 25 of mo with progesterone added for last 12 days) or daily coadministration of estrogen plus progesterone on daily basis. In a woman without uterus, use of cyclic therapy and/or therapy with progesterone is not necessary.
