How T-Mycin Plus works
T-Mycin Plus is a combination of two medicines: Dexamethasone and Tobramycin. Dexamethasone is a steroid which blocks the production of certain chemical messengers (prostaglandins) that make the eye red, swollen and itchy. Tobramycin is an antibiotic. It stops bacterial growth in the eye by preventing the synthesis of essential proteins required by bacteria to carry out vital functions.
