Nausea/vomiting, bloating, breast tenderness, headache, or weight changes may occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor right away if you have any serious side effects, including: nausea/vomiting that doesn't stop, mental/mood changes (such as depression, memory loss), breast lumps, unusual vaginal bleeding (such as spotting, breakthrough bleeding, prolonged/recurrent bleeding), increased or new vaginal irritation/itching/odor/discharge, severe stomach/abdominal pain, yellowing eyes/skin, dark urine, swelling hands/ankles/feet, increased thirst/urination.

This medication may rarely cause serious (sometimes fatal) problems from blood clots (such as heart attack, stroke, blood clots in the lungs or legs).

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.

Some products that may interact with this drug include: aromatase inhibitors (such as anastrozole, exemestane, letrozole), fezolinetant, fulvestrant, ospemifene, raloxifene, tamoxifen, toremifene, tranexamic acid.

This medication may interfere with certain lab tests, possibly causing false test results. Make sure lab personnel and all your doctors know you use this drug.

Estrogens, either used alone or with another hormone (progestin), have rarely caused very serious side effects. Discuss the risks and benefits of hormone treatment with your doctor. Estrogens should not be used to prevent heart disease or dementia.

Estrogens can increase the risk of cancer of the uterus (endometrial cancer). Taking a progestin as directed by your doctor can help decrease this risk. Tell your doctor right away if you have any unusual vaginal bleeding.

In postmenopausal women, estrogens, taken with or without a progestin, increase the risk of cancer of the breast/ovaries, stroke, dementia, and serious blood clots. When used along with a progestin, estrogens also increase the risk of heart disease (such as heart attacks).

The risk for serious side effects may depend on the dose of estrogen and the length of time it is used. This medication should be used at the lowest effective dose and for the shortest amount of time. Discuss the use of this medication with your doctor regularly (for example, every 3 to 6 months) to see if you still need to use it. If you will be taking this medication long-term, you should have regular complete physical exams (for example, once a year) as directed by your doctor. See also Notes section.

This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional.

Certain estrogen products may also be prescribed for bone loss (osteoporosis) in women after menopause. However, there are other medications (such as raloxifene, bisphosphonates including alendronate) that are also effective in preventing bone loss and may be safer. These medications should be considered for use before estrogen treatment.

Tell your doctor if you just had or will be having surgery, or if you will be confined to a chair or bed for a long time (such as a long plane flight).
