These reactions can be life-threatening, and patients should seek medical attention immediately if symptoms such as skin ulcers, peeling, or fever occur. Treatment may require discontinuation of dabrafenib and appropriate supportive care.

2.Bleeding

Dabrafenib may increase the risk of bleeding, manifested as skin congestion, blood in urine, and vomiting blood.

3. Special side effects of combined medication

When dabrafenib is used in combination with MEK inhibitors (such as trametinib), the incidence of certain side effects may increase, such as fever, rash, joint pain, etc. Therefore, patients should closely monitor their condition during combined medication and seek medical advice promptly if they feel unwell.

Dabrafenib has significant efficacy in the treatment of BRAF V600E mutation-related tumors, but it may also cause a variety of side effects. Patients should use this drug under the guidance of a doctor, conduct relevant examinations regularly, and detect and deal with side effects in a timely manner.
