What are the possible side effects of vemurafenib/zobovo?

Vemurafenib/zobovo(Vemurafenib), as a BRAF inhibitor, plays an important role in the treatment of melanoma, but like all targeted drugs, its use may be accompanied by certain adverse reactions. During the period of taking the medicine, patients need to closely observe physical changes and deal with side effects in a timely manner under the guidance of professional doctors to ensure efficacy and safety.

Among the common adverse reactions, skin-related symptoms are more prominent. Because vemurafenib affects the differentiation and growth of skin cells, some patients may experience rashes, photosensitivity reactions, and even hyperkeratosis. In daily life, patients need to pay attention to sun protection and avoid prolonged exposure to ultraviolet rays, which can help reduce the risk of skin toxicity.

Rarely, new skin lesions may develop, including squamous cell carcinoma or keratoacanthoma, so your doctor will usually check the skin condition regularly during follow-up visits. In addition to skin reactions, vemurafenib may also cause systemic discomfort such as joint pain, fatigue, and loss of appetite. Some patients may experience hair loss or nail changes. Although these side effects are not life-threatening, they will have a certain impact on their quality of life. Gastrointestinal reactions, such as nausea, diarrhea, or oral discomfort, have also been reported in people who use them and usually resolve with supportive care or dietary modification.

In a few cases, vemurafenib may also affect cardiac function, manifested as abnormal electrocardiogram or prolongation of the QT interval. This requires doctors to conduct regular ECG monitoring to ensure the safety of medication. In addition, changes in liver function indicators also occur in some patients, so hematology and liver and kidney function tests are often arranged during treatment to detect potential risks in a timely manner.
