Oxytetracycline is usually not able to treat smelly feet. Because hyoscine is an antibiotic, the indications for this drug are mainly for soft tissue infections of the skin, or bacterial infections of the body, and foot odor is mainly due to fungal infections. If fungal infections form foot odor using hyoscine for treatment, whether oral or topical, may induce local dysbiosis and thus aggravate the fungal infection, which may lead to the aggravation of foot odor. In addition, some foot odor is formed due to oedema, which is mostly caused by the abnormal secretion of sweat glands in the feet, so the sweat secreted appears to have an abnormal pungent smell, and there is no basis for using hyoscine to treat it. Some foot odor may also be due to eczema or abnormal sweating of the feet and the formation of impregnation reaction, which can be treated with eczema-related medication, but not with hyoscine.
