WARNING: ESTROGENS INCREASE THE RISK OF ENDOMETRIAL CANCER.

CLOSE CLINICAL SURVEILLANCE OF ALL WOMEN TAKING ESTROGENS IS IMPORTANT. ADEQUATE DIAGNOSTIC MEASURES, INCLUDING ENDOMETRIAL SAMPLING WHEN INDICATED, SHOULD BE UNDERTAKEN TO RULE OUT MALIGNANCY IN ALL CASES OF UNDIAGNOSED PERSISTENT OR RECURRING ABNORMAL VAGINAL BLEEDING. THERE IS CURRENTLY NO EVIDENCE THAT THE USE OF “NATURAL” ESTROGENS RESULTS IN A DIFFERENT ENDOMETRIAL RISK PROFILE THAN SYNTHETIC ESTROGENS OF EQUIVALENT ESTROGEN DOSE.

CARDIOVASCULAR AND OTHER RISKS 

ESTROGENS WITH AND WITHOUT PROGESTINS SHOULD NOT BE USED FOR THE PREVENTION OF CARDIOVASCULAR DISEASE OR DEMENTIA.

THE WOMEN’S HEALTH INITIATIVE (WHI) STUDY REPORTED INCREASED RISKS OF MYOCARDIAL INFARCTION, STROKE, INVASIVE BREAST CANCER, PULMONARY EMBOLI, AND DEEP VEIN THROMBOSIS IN POSTMENOPAUSAL WOMEN (50 TO 79 YEARS OF AGE) DURING 5 YEARS OF TREATMENT WITH ORAL CONJUGATED ESTROGENS (CE 0.625 MG) COMBINED WITH MEDROXYPROGESTERONE ACETATE (MPA 2.5 MG) RELATIVE TO PLACEBO.

THE WOMEN’S HEALTH INITIATIVE MEMORY STUDY (WHIMS), A SUBSTUDY OF WHI, REPORTED INCREASED RISK OF DEVELOPING PROBABLE DEMENTIA IN POSTMENOPAUSAL WOMEN 65 YEARS OF AGE OR OLDER DURING 4 YEARS OF TREATMENT WITH ORAL CONJUGATED ESTROGENS PLUS MEDROXYPROGESTERONE ACETATE RELATIVE TO PLACEBO. IT IS UNKNOWN WHETHER THIS FINDING APPLIES TO YOUNGER POSTMENOPAUSAL WOMEN.

OTHER DOSES OF ORAL CONJUGATED ESTROGENS WITH MEDROXYPROGESTERONE ACETATE, AND OTHER COMBINATIONS AND DOSAGE FORMS OF ESTROGENS AND PROGESTINS WERE NOT STUDIED IN THE WHI CLINICAL TRIALS AND, IN THE ABSENCE OF COMPARABLE DATA, THESE RISKS SHOULD BE ASSUMED TO BE SIMILAR. BECAUSE OF THESE RISKS, ESTROGENS WITH OR WITHOUT PROGESTINS SHOULD BE PRESCRIBED AT THE LOWEST EFFECTIVE DOSES AND FOR THE SHORTEST DURATION CONSISTENT WITH TREATMENT GOALS AND RISKS FOR THE INDIVIDUAL WOMAN.

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Climara falls into category X. Climara should now be used during pregnancy. There appears to be little or no increased risk of birth defects in children born to women who inadvertently used estrogens during early pregnancy. Talk to your doctor right away if you become pregnant while using Climara.

Tell your doctor if you are breastfeeding or plan to breastfeed.

Climara has been detected in human breast milk. Estradiol can decrease the quality or quantity of breast milk. A choice should be made whether to stop nursing or to stop use of this medication. The importance of the drug to the mother should be considered.

Estrogens increase the chance of getting cancer of the uterus.

Do not use estrogens to prevent heart disease, heart attacks, or strokes.
