Does Sorafenib/Nexavar have side effects and what are their manifestations?

Sorafenib/Nexavar (Sorafenib) is a small molecule multi-target targeted drug. Although it plays an important role in the treatment of tumors such as hepatocellular carcinoma, renal cell carcinoma, and thyroid cancer, patients often face side effects during use. Side effects are inevitable for all targeted drugs, because while drugs inhibit tumor signaling pathways, they may also affect the physiological functions of some normal cells. For sorafenib, the side effects are relatively complex, but most can be managed through dose adjustment or supportive care.

Common clinical side effects include hand-foot skin reactions, that is, patients may experience redness, pain, peeling, and even blisters on the palms and soles of the feet. This reaction is particularly typical during sorafenib treatment and is considered to be caused by the drug's inhibition of angiogenesis and its impact on small blood vessels in the skin. In addition, digestive tract discomfort is also a common symptom, including diarrhea, nausea, loss of appetite, etc. Most of these symptoms appear in the early stages of treatment, and some patients can gradually alleviate them after adapting. Fatigue and decreased physical strength are also common experiences among patients. This is because drugs can also affect the body's metabolic balance while inhibiting tumor growth.

In addition, sorafenib may also affect blood pressure. Some patients develop high blood pressure during the medication, which requires close monitoring by a doctor and control with antihypertensive drugs. Skin side effects may also manifest as rash and hair loss, most of which are reversible reactions. During long-term medication, a small number of patients may experience abnormal liver function indicators, so regular monitoring of liver and kidney function is necessary. Guidelines generally agree that patients should undergo comprehensive follow-up during the use of sorafenib in order to detect and deal with adverse reactions in a timely manner.
