The glucose and insulin responses to oral glucose tolerance tests and lipid values in normal women taking a triphasic pill containing norethindrone (Ortho 7/7/7) were performed. After three months, no significant changes in these metabolic indices were found. These results confirm and expand the knowledge regarding the metabolic safety of norethindrone-containing triphasic formulations.
