Side effects vary with different targeted drugs, such as HER-2 positive targeted drugs, monoclonal antibody-based targeted drugs, and targeted drugs for gene mutations. Most of them may cause diarrhea, lowering of white blood cells, abnormalities in liver and kidney functions, skin rashes and inflammation of mucous membranes.
1. HER-2-positive targeted drugs: patients treated with HER-2-positive targeted drugs, the main side effects are diarrhea, and if combined with other chemotherapeutic drugs during treatment, there may also be a decrease in white blood cells and platelets, fatigue and so on.
2. Monoclonal antibody targeted drugs: high blood pressure, proteinuria, liver and kidney function abnormalities and other side effects may occur.
3. Targeted drugs for gene mutation: during the treatment of tyrosine kinase inhibitors with gene mutation, patients are prone to side effects such as rash, itching, mucous membrane inflammation, mouth ulcers, diarrhea, etc.
So different targeted drugs have different focuses of treatment, and a variety of side effects can occur. It is necessary to use the drug under the guidance of a doctor.
