Evista (raloxifene) is an oral medication used to prevent and treat a bone condition called osteoporosis in postmenopausal people. It is also used to reduce the risk of breast cancer in postmenopausal people at high risk.
Evista is a selective estrogen receptor modulator. These medications chemically resemble the hormone estrogen and bind to estrogen receptors in different parts of the body. Estrogen receptors are found in tissues like the uterus, breast, or bone. The specific effect of the drug depends on the type of tissue.
Evista is available in tablet form.
Generic Name: Raloxifene
Brand Name(s): Evista
Drug Availability: Prescription
Administration Route: Oral
Therapeutic Classification: Endocrine-metabolic agent
Available Generically: Yes
Controlled Substance: N/A
Active Ingredient: Raloxifene hydrochloride
Dosage Form(s): Tablet
When Evista binds to an estrogen receptor, it can have effects that mimic estrogen (like in bone, where it helps maintain bone strength) or oppose estrogen (like in the breast).
The Food and Drug Administration (FDA) approved Evista to prevent and treat and prevent osteoporosis in post-menopause. It has been shown to reduce the bone loss associated with menopause and lower the risk of vertebral (spine) fractures.
Evista is also approved to prevent breast cancer in people at high risk for developing the disease. Your risk of breast cancer depends on your age, family history, and personal history of breast disease. Talk to your healthcare provider about how your breast cancer risk is determined and whether you would benefit from this medication.
Evista should not be used in pre-menopause.
Take Evista exactly as prescribed by your healthcare provider. It can be taken at any time of the day, with or without food. Evista is supplied as 60-milligram tablets, usually taken once a day. If you are taking Evista for osteoporosis, your healthcare provider may also prescribe calcium and vitamin D supplementation. These can be taken at the same time as your medication.
Because Evista can increase the risk of developing blood clots, try not to stay seated the whole time during long car or plane trips. Remember to move around periodically.
If you need major surgery or will be on long-term bed rest, you will need to stop taking Evista at least three days ahead of time. Tell your healthcare provider who treats you that you take this medication. You may not be able to restart the medicine until you are active again.
Store your Evista tablet at room temperature (between 68 degrees and 77 degrees F). Like all medications, keep them out of reach of children and pets. Do not store your medication in the bathroom.
Sometimes, healthcare providers prescribe drugs “off-label” for conditions not specifically mentioned in the product label.
Evista is only FDA-approved for postmenopausal people who have never had breast cancer. However, some with a history of having breast cancer may be prescribed Evista to prevent their tumor from returning. People with osteoporosis may be prescribed Evista after receiving androgen deprivation therapy (most often given for prostate cancer).
This is not a complete list of side effects and others may occur. A healthcare provider can advise you on side effects. If you experience other effects, contact your pharmacist or a healthcare provider. You may report side effects to the FDA at fda.gov/medwatch or 1-800-FDA-1088.
The most common side effects of Evista include:
Hot flashes are most common in the first six months of treatment.
There are a few serious safety risks associated with Evista that you should know about.
Evista increases the chances for blood clots to form in your body. This can take the form of clots in the veins of the legs (deep vein thrombosis, or DVT) or lungs (pulmonary embolism, or PE). People who have a history of heart attacks or are at increased risk of heart attack have an increased risk of dying of stroke while on Evista.
For this reason, people with a history of blood clots (in the legs, lungs, or eyes) should not take Evista.
Evista may cause other side effects. Call your healthcare provider if you have any unusual problems while taking this medication.
If you experience a serious side effect, you or your healthcare provider may send a report to the FDA's MedWatch Adverse Event Reporting Program or phone at 800-332-1088.
It is very important that you keep your appointments with your doctor even if you feel well.
Before you have any kind of surgery, tell the medical doctor in charge that you are using this medicine. Discuss discontinuing use of raloxifene 3 days before you think you will have a long period of inactivity, sitting, or bed rest, such as after having surgery or going on a long trip. The doctor may have you start the medicine again after you are back on your feet and fully mobile. If you are going on a trip and stay on raloxifene, you should walk regularly or move about when possible. Remaining still for long periods may cause blood clots for some people, and raloxifene may rarely worsen their condition.
If you are able to become pregnant, stop using the medicine immediately if you think you have become pregnant and check with your doctor. Raloxifene is recommended for women who are past menopause.
Raloxifene does not act like an estrogen to stimulate the uterus or breast. If you experience vaginal bleeding, breast pain or enlargement, or swelling of hands or feet while on raloxifene, you should report it to your doctor.
Other ways that may be used with raloxifene to help prevent or treat bone loss are taking calcium plus vitamin D supplements and getting weight-bearing exercise. You may want to discuss these options with your doctor.
Evista should be used with caution if you have liver or kidney disease, as this can affect how the drug is metabolized (processed) by the body. Make sure your healthcare provider knows your medical history before starting therapy with Evista.
If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and only take your next regularly scheduled dose. Don’t take an extra dose to make up for the missed one.
Evista overdoses are rare, and no deaths have been reported due to taking too much of this medication. If you take too much Evista, you may experience side effects like leg cramps and dizziness.
If you think you or someone else may have overdosed on Evista, call a healthcare provider or the Poison Control Center (800-222-1222).
If someone collapses or isn't breathing after taking Evista, call 911 immediately.
You should not take Evista if:
Evista has important drug interactions, so make sure your prescribing healthcare provider knows all the medications, herbs, and supplements you are taking.
Evista may interact with the following:
Evista belongs to a drug class called selective estrogen receptor modulators, or SERMS. These drugs can both mimic and oppose the effects of estrogen. For example, Evista acts like estrogen to increase bone strength. However, its anti-estrogen effects can help treat breast cancer.
Other SERMS are tamoxifen (the oldest member of this drug class) and Fareston (toremifene), both used to treat breast cancer.
Evista is used in postmenopausal people to prevent and treat osteoporosis. It has been shown to reduce the bone loss associated with menopause and lower the risk of vertebral (spine) fractures.
Evista is also approved to prevent breast cancer in people at high risk for developing the disease. Breast cancer risk can depend on your age, family history, and personal history of breast disease.
Evista is a type of medicine called a selective estrogen receptor modulator. These are medications that bind to estrogen receptors in different parts of the body, acting like estrogen in some tissues but opposing the effects of estrogen in others.
Evista’s common side effects include hot flashes, leg cramps or swelling, flu-like symptoms, joint pain, and sweating. Hot flashes are most common in the first six months of treatment.
There are also a few serious safety risks associated with Evista. Evista increases the chances for blood clots to form in your legs (deep vein thrombosis, or DVT) or lungs (pulmonary embolus, or PE). People who have a history of heart attacks, or are at increased risk of heart attack, have an increased risk of dying of stroke while on Evista.
Remember that Evista can increase your risk for blood clots in your lungs or legs. Staying still for a long time (like during a long trip or in bed during an illness) can further increase this risk. Talk to your healthcare provider about how to stay healthy and prevent any complications of Evista. Some recommendations may include temporarily stopping your medication before having surgery and trying to move around periodically while on long plane or car rides.
Keep an eye out for blood clot symptoms, including leg pain, swelling, chest pain, or shortness of breath. Get medical attention immediately if you experience these symptoms while being treated with Evista.
