What are the side effects of targeted drugs

Side effects of targeted drugs include rash, diarrhea, hypertension, fatigue, hand-foot syndrome, etc. 1. Rash rash is one of the common side effects of targeted drugs. This is due to the drug's effect on skin cells, which may lead to redness, itching, pimples, etc. Severe rash may affect the patient's quality of life, and even require drug dose adjustment or treatment suspension. 2. Diarrhea is also a common manifestation. Targeted drugs may interfere with the normal function of the intestine, resulting in increased intestinal motility and reduced water absorption, resulting in diarrhea. Persistent diarrhea may lead to dehydration and electrolyte disorders that need to be treated promptly. 3. Hypertension Hypertension may occur after the use of certain targeted drugs. This is because the medication affects the regulation of blood vessels, causing blood pressure to rise. Patients need to monitor blood pressure closely and give antihypertensive medication if necessary. 4. Fatigue often makes patients feel weak and sleepy. This may be caused by the effects of the medication on metabolism and energy, as well as on the immune system. Severe fatigue may limit the patient's daily activities. 5. Hand-foot syndrome Hand-foot syndrome is characterized by redness, pain, peeling, etc. of the palms and soles. It affects the patient's walking and hand activities and brings inconvenience to life.
