Feza 50 Capsule belongs to a class of drugs known as antileprotic medicines. It is used in combination with other medicines for the treatment of leprosy. It works by stopping the growth of disease-causing organisms in the body. Feza 50 Capsule should be used in the dose and duration as advised by your doctor. It should be taken with food, preferably at a fixed time. Avoid skipping any doses and finish the full course of treatment even if you feel better. Do not take a double dose to make up for a missed dose. Simply take the next dose as planned. Some people may experience nausea, stomach upset, and vomiting as the side effects of this medicine. It may also discolor your skin, urine, saliva, tears, and other body fluids. This is normally temporary and resolves once the treatment is completed. Please consult your doctor if these side effects bother you or persist for a longer duration.
