Summary
Toremifene is used to treat certain types of breast cancer, particularly in postmenopausal women. It is effective for hormone-responsive breast cancer, which relies on estrogen to grow. By blocking estrogen receptors, Toremifene helps slow or stop cancer growth. It is often used alongside other therapies to improve outcomes.
Toremifene works by blocking estrogen receptors, which are parts of cells that estrogen, a hormone, attaches to. Estrogen can promote the growth of certain breast cancer cells. By blocking these receptors, Toremifene helps slow or stop the growth of cancer cells, acting like a switch that turns off cancer growth.
The usual dose of Toremifene for adults is 60 mg taken once daily. It can be taken with or without food. It's important to follow your doctor's instructions regarding dosage. If you miss a dose, take it as soon as you remember unless it's close to your next dose. Do not double up on doses.
Common side effects of Toremifene include hot flashes, which are sudden feelings of warmth, sweating, and dizziness. These side effects are generally mild to moderate and vary from person to person. If you experience new symptoms after starting Toremifene, they might be temporary or unrelated to the medication.
Toremifene can increase the risk of blood clots, which are clumps of blood that can block blood vessels, and may cause changes in heart rhythm, known as QT prolongation. It should not be used if you have a known allergy to it or its ingredients. Always inform your doctor about any heart conditions or other medications you are taking.
