People who are prone to colds may consider using Thymofaxine. Thymofaxine is a kind of immune booster, which is mainly used for the treatment of chronic hepatitis B and enhancing the immune response to viral vaccines. People with low immune function who are prone to catching colds may consider using Thymofaxine to enhance their immune system, but it should be noted that it should not be used by patients who are allergic to the ingredients of the drug, or those who are using immunosuppressive drugs. If you are prone to catching colds in daily life, it is also recommended to gradually improve your immunity by strengthening exercise and nutrition, as well as increasing or decreasing clothing according to the increase in temperature to prevent colds scientifically, and if special populations do need to prevent colds through medication, they need to follow the doctor’s instructions for reasonable and standardized use of medication.
