bazedoxifene - conjugated estrogens
This combination product contains 2 medications: conjugated estrogens and bazedoxifene.
- Estrogen belongs to the class of drugs called hormones. It is a female hormone that is produced by the ovaries. Once menopause is reached, the ovaries produce less estrogen and symptoms of menopause can occur.
- Bazedoxifene belongs to the class of medications called selective estrogen receptor modulators (SERMs). It prevents the estrogen from working in some parts of the body, preventing overgrowth of the lining of the uterus.
Together, they are used to help control episodes of sweating and sensation of heat, often referred to as "hot flashes" and "night sweats," associated with menopause.

These factors may affect how you should use this medication.
Note the following important information about estrogen replacement therapy:
The Women's Health Initiative (WHI) study results indicated an increased risk of heart attack, stroke, breast cancer, blood clots in the lungs, and blood clots in the leg veins in postmenopausal women during 5 years of treatment with 0.625 mg conjugated equine estrogens and 2.5 mg medroxyprogesterone compared to women receiving sugar tablets. Other combinations of estrogen and progestins were not studied. However, until additional data are available, the risks should be assumed to be similar for other hormone replacement products. This means the following:
- Estrogens with or without progestins should be used at the lowest dose that relieves your menopausal symptoms for the shortest time period possible, as directed by your doctor.
- Estrogens with or without progestins should not be used to prevent heart disease, heart attacks, or strokes.
Blood clotting disorders: The use of estrogens is associated with an increased risk of blood clots in the lungs (pulmonary embolism) and legs (deep vein thrombosis). If you have or have had a heart attack, stroke, heart disease, a blood clot in your leg, or medical conditions that increase your risk of blood clots, you should not use this medication.
The risk of developing blood clots also increases with age, a personal or family history of blood clots, smoking, and obesity. It is also increased if you are immobilized for prolonged periods or have major surgery. If possible, this medication should be stopped 4 weeks before major surgery. Talk about the risk of blood clots with your doctor.
Blood pressure: Women may experience increased blood pressure when using estrogen replacement therapy. Talk to your doctor about how often you should have your blood pressure checked.
Bone disease: If you have bone disease due to cancer or a metabolic condition causing too much calcium in your body, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Breast and ovarian cancer: Studies indicate an increased risk of breast and ovarian cancer with long-term use of estrogen replacement therapy. Women with a history of breast cancer should not use estrogens. Women who have breast nodules, fibrocystic disease, abnormal mammograms, or a strong family history of breast cancer should be closely monitored by their doctor.
Women taking estrogens should have regular breast examinations and should be instructed in breast self-examination. The estradiol patch must not be applied to the breasts, as it may have harmful effects on the breast tissue.
Dementia: Women over the age of 65 receiving combined hormone replacement therapy (estrogen and progestin or estrogen alone) may be at increased risk of developing dementia (loss of memory and intellectual function). If you are over 65, talk to your doctor about whether you should be tested for dementia.
Diabetes: Estrogens may affect blood sugar control. If you have diabetes or are at risk of developing diabetes (e.g., have a family history of diabetes, have high blood pressure or high cholesterol, or are obese), carefully monitor your blood glucose levels while using this medication.
Endometrial cancer: There is evidence from several studies that estrogen replacement therapy can increase the risk of cancer of the endometrium (lining of the uterus). Taking a SERM, such as bazedoxifene, along with the estrogen reduces this risk of endometrial cancer.
Break-through bleeding may occur early in treatment with this medication. If you develop any abnormal vaginal bleeding later on while using this medication, contact your doctor. If you have or have had endometrial cancer, you should not use this medication.
Endometriosis: Estrogen replacement therapy can cause endometriosis to reappear or get worse. If you have or have had endometriosis, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Fibroids: This medication may worsen fibroids by causing sudden enlargement, pain, or tenderness. If you notice these effects, contact your doctor.
Fluid retention: Estrogen may cause fluid retention, and worsen heart disease, kidney disease, or asthma. Talk to your doctor if you have any concerns. If you experience worsening of these conditions while using this medication, contact your doctor.
Follow-up examinations: It is important to have a follow-up examination 3 to 6 months after starting this medication to assess your response to treatment. Examinations should be done at least once a year after the first one.
Gallbladder disease: This medication can aggravate gallbladder disease or increase the risk of developing it. If you have gallbladder disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Heart disease and stroke: Studies indicate an increased risk of heart disease and stroke with estrogen for postmenopausal women. If you experience symptoms of a heart attack (chest pain, tightness or pressure, sweating, nausea, feeling of impending doom) or stroke (sudden dizziness, headache, loss of speech, changes in vision, weakness or numbness in the arms and legs) while taking this medication, get immediate medical attention.
High cholesterol or triglycerides: Estrogen and bazedoxifene may increase triglyceride levels in those who already have high levels. If you have increased cholesterol or triglycerides, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Kidney function: Estrogen can affect how calcium and phosphorus are used by your body. If you have kidney disease, this may be a concern and you should discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Liver function: If you have reduced liver function, you may require special monitoring by your doctor while you use this medication. Make sure to tell your doctor if you have ever had liver problems. People with active liver disease or liver tumours should not use estrogen.
If you experience symptoms of liver problems (e.g., yellowing of the skin or eyes, abdominal pain, loss of appetite, dark urine, pale stools, nausea, or vomiting), contact your doctor immediately.
Migraine headaches: If you have migraines with aura (headache is associated with symptoms such as flashes of light, tingling sensations, blind spots, muscle weakness, and difficulty speaking either before or during the headache), you should not use this medication.
For some people who experience migraine headaches, estrogen can aggravate the condition. Talk to your doctor if you notice any change in your migraine pattern while using estrogen.
Seizures: Estrogens may increase your risk of having a seizure. If you have a seizure disorder or a history of seizures, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Thyroid disease: Estrogen may affect how thyroid hormone is used by the body. If you are taking thyroid medication to supplement an underactive thyroid gland, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Pregnancy: Estrogen should not be used during pregnancy. If you become pregnant while taking this medication, contact your doctor immediately.
Breast-feeding: This medication passes into breast milk. If you are a breast-feeding mother and are taking estrogen, it may affect your baby. This medication is not recommended for breast-feeding women.
Children: This medication is not intended for children or adolescents.
Seniors: The safety and effectiveness of this medication have not been determined for adult women older than 75 years of age.
