WARNING: ENDOMETRIAL CANCER, CARDIOVASCULAR DISORDERS, AND PROBABLE DEMENTIA • Women taking DUAVEE should not take additional estrogens [see Warnings and Precautions (5.1) ] • There is an increased risk of endometrial cancer in a woman with a uterus who uses unopposed estrogens.

Therefore, the relevance of the WHI findings regarding adverse cardiovascular events and dementia to lower CE doses, other routes of administration, or other estrogen-alone products is not known.

• Women taking DUAVEE should not take additional estrogens ( 5.1 )

• Women taking DUAVEE should not take progestins, additional estrogens or additional estrogen agonist/antagonists ( 5.1 )

Women taking DUAVEE should not take additional estrogens as this may increase the risk of endometrial hyperplasia.

Effects of CHCs on Other Drugs CHCs containing ethinyl estradiol may inhibit the metabolism of other compounds (e.g., cyclosporine, prednisolone, theophylline, tizanidine, and voriconazole) and increase their plasma concentrations.

The effects of other antibiotics on etonogestrel or ethinyl estradiol concentrations have not been evaluated.
