Thymofacine is not recommended for normal people. Thymofaxine is an immune-boosting medication whose main effect is to treat or assist in the treatment of disease and improve the body’s resistance. It is used in the treatment of chronic hepatitis B and as an immune response booster for vaccines. Thymofaxine is an adjunctive treatment for viral infections or tumors, and can increase the body’s resistance to viral infections and adverse reactions caused by tumor treatment drugs. Common adverse reactions are: ① dermatologic system, local discomfort, erythema, rash at the injection site; ② musculoskeletal system, transient muscle atrophy, polyarthralgia combined with hand edema. For normal people, the immune response function and resistance are basically normal, and it is not necessary to use thymofaxine to stimulate immune function and improve resistance. Thymofaxine should be used in consultation with and under the supervision of a physician.
