التداخل بين إستراديول ودينوجيست وبريدنيزولون

Estrogens, including oral contraceptives: Estrogens may decrease the hepatic metabolism of certain corticosteroids thereby increasing their effect.

Interference with Laboratory Tests The use of contraceptive steroids may influence the results of certain laboratory tests, such as coagulation factors, lipids, glucose tolerance, and binding proteins [see Warnings and Precautions ( 5.11 ) and Drug Interactions ( 7.2 )].

Steroid hormones may be poorly metabolized in patients with impaired liver function.

Antibiotics : There have been reports of pregnancy while taking hormonal contraceptives and antibiotics, but clinical pharmacokinetic studies have not shown consistent effects of antibiotics on plasma concentrations of synthetic steroids.
