Festive MZ Syrup is an antibiotic medicine given to children for the treatment of a wide range of bacterial and parasitic infections. These infections may include tooth abscess, gum infection, pneumonia, diarrhea, dysentery, burning sensation while passing urine, and genital tract infection. Festive MZ Syrup inhibits the growth of infection-causing organisms by stopping them from multiplying. It is most likely that your child’s infection will start showing improvement within 3 to 5 days of the regular dosing. Make sure to complete the full course of treatment even if your child feels better. Stopping the medicine abruptly by yourself may worsen your child’s condition or cause infection recurrence.
