Description
Studies in animals or humans have demonstrated fetal abnormalities and/or there is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience, and the risks involved in use of the drug in pregnant women clearly outweigh potential benefits.
Mode of Action
Estriol is a naturally occurring oestrogen. It induces normalization of vag epithelium. It is claimed to have only a mild proliferative effect on the endometrium. It only has a short retention time in the nuclei of endometrial cells.
Interaction
Reduced efficacy may occur when used with activated charcoal, barbiturates, carbamazepine, griseofulvin, hydantoin and rifampicin. May possibly change efficacy of oral anticoagulants and increase pharmacologic effects of succinylcholine, theophyllines and troleandromycin.
