Used to treat a variety of bacterial infections, including those of the ear, throat (such as tonsillitis and pharyngitis), chest and lungs (like bronchitis), and urinary tract (such as cystitis and urethritis). It is effective against both gram-positive and gram-negative bacteria and is often prescribed when penicillin cannot be used. Cefixime trihydrate is commonly used in pediatric and adult patients due to its once- or twice-daily dosing and good tolerability. It works by stopping the growth of bacteria, helping the body's immune system to clear the infection.
