Possible adverse reactions and treatment methods caused by Fulvestrant/Fuxit

Fulvestrant is a drug commonly used to treat hormone receptor-positive breast cancer, especially those who are resistant to tamoxifen or other hormone treatments. As a steroid drug, the main mechanism of action of fulvestrant is to inhibit the growth and spread of tumors by inhibiting the function of estrogen receptors and reducing hormone levels. However, like many drugs, the use of fulvestrant may also cause some adverse reactions, and patients should pay special attention during use.

Common adverse reactions to fulvestrant include injection site reactions, nausea, headache, fatigue, and muscle or joint pain. These side effects are generally mild and usually resolve over time. For example, injection site reactions such as pain, redness, swelling, and induration are among the most common side effects. To relieve these discomforts, patients are advised to apply ice appropriately after the injection and keep the injection site clean. In addition, if severe discomfort or reaction occurs, you may consider adjusting the frequency of injections or taking other treatments.

Some patients may experience nausea, vomiting, or gastrointestinal upset. In this regard, you can reduce symptoms by adjusting your diet, avoiding excessively greasy foods, or using antiemetic drugs. Headache and fatigue are another common side effect of fulvestrant, which may be related to the drug's effect on hormone levels in the body. In this case, rest and hydration can provide effective relief. For muscle or joint pain, patients can try warm compresses or over-the-counter pain relievers, and consult their doctor to adjust their treatment plan if necessary.

Although most adverse reactions are mild and temporary, fulvestrant may also cause some serious side effects, such as abnormal liver function or allergic reactions. Abnormal liver function usually manifests as jaundice, nausea, loss of appetite, and right upper quadrant pain. If patients experience these symptoms, they should stop taking the medication immediately and seek professional medical help. An allergic reaction may appear as a rash, difficulty breathing, or swelling of the throat. At this time, the patient should seek medical treatment immediately.
