From the Guidelines
Patients taking Evista (raloxifene) should be aware of the potential red flags of side effects, including blood clots, stroke symptoms, severe allergic reactions, and unusual vaginal bleeding, as these can have a significant impact on morbidity, mortality, and quality of life. The most serious concern is blood clots, so patients should seek immediate medical attention for symptoms like leg pain, swelling, warmth, or redness; chest pain; sudden shortness of breath; or coughing up blood 1. Other concerning side effects include stroke symptoms (sudden numbness, confusion, vision problems, severe headache), severe allergic reactions (rash, itching, swelling, severe dizziness, trouble breathing), and unusual vaginal bleeding. Some key points to consider when evaluating the risk of side effects in patients taking Evista include:
- The risk of blood clots, including deep vein thrombosis and pulmonary embolism, is increased in patients taking raloxifene, particularly in those with a history of thromboembolic events 1.
- The risk of stroke and transient ischemic attack is also increased in patients taking raloxifene, particularly in those with a history of cerebrovascular disease 1.
- Raloxifene can cause severe allergic reactions, including anaphylaxis and angioedema, in rare cases 1.
- Unusual vaginal bleeding is a potential side effect of raloxifene, particularly in postmenopausal women 1. More common but less dangerous side effects include:
- Hot flashes
- Leg cramps
- Swelling in hands/feet
- Flu-like symptoms
- Joint pain
- Sweating It's essential to weigh the benefits of Evista against the risk of side effects, particularly in patients at increased risk of breast cancer or osteoporosis 1. The medication works by acting as a selective estrogen receptor modulator, providing estrogen-like effects on bones while blocking estrogen effects in breast and uterine tissue. In terms of management, patients taking Evista should be monitored regularly for signs and symptoms of side effects, and the medication should be discontinued if any serious side effects occur 1. Additionally, patients should be educated on the potential risks and benefits of Evista and should be encouraged to report any concerns or symptoms to their healthcare provider promptly.
From the FDA Drug Label
Increased risk of blood clots in the legs (deep vein thrombosis) and lungs (pulmonary embolism) have been reported with raloxifene hydrochloride tablets Women who have or have had blood clots in the legs, lungs, or eyes should not take raloxifene hydrochloride tablets. Women who have had a heart attack or are at risk for a heart attack may have an increased risk of dying from stroke when taking raloxifene hydrochloride tablets. Stop taking raloxifene hydrochloride tablets and call your doctor if you have: leg pain or a feeling of warmth in the lower leg (calf). swelling of the legs, hands, or feet sudden chest pain, shortness of breath, or coughing up blood. sudden change in your vision, such as loss of vision or blurred vision.
The red flags of side effects in a patient taking Evista (Raloxifene) include:
- Blood clots: leg pain, swelling of the legs, hands, or feet
- Cardiovascular events: sudden chest pain, shortness of breath, or coughing up blood
- Vision changes: sudden change in vision, such as loss of vision or blurred vision These side effects can be serious and life-threatening, and patients should stop taking the medication and call their doctor immediately if they experience any of these symptoms 2.
From the Research
Red Flags of Side Effects in Patients Taking Evista (Raloxifene)
The following are potential red flags of side effects in patients taking Evista (Raloxifene) [(3,4,5,6,7)]:
- Increased risk of venous thromboembolism [(3,4,5,7)]
- Increased risk of fatal stroke [(3,5)]
- Increased risk of deep vein thrombosis or pulmonary embolism 7
- Potential risk of thromboembolism 4
- No significant increase in the risk of endometrial cancer 7
- No significant effect on the risk of primary coronary events 6
Monitoring Requirements
Patients taking Evista (Raloxifene) should be carefully monitored for:
- Thromboembolism 4
- Venous thromboembolic events [(3,7)]
- Fatal stroke [(3,5)]
Special Considerations
The choice of chemoprevention agent, including Evista (Raloxifene), must consider a risk-benefit assessment for each individual patient 3. Additionally, patients with a history of breast cancer or those taking estrogen should be excluded from taking Evista (Raloxifene) 7.
