Omnicef-O 100mg Oral Suspension contains Cefixime, a third-generation cephalosporin antibiotic, at a concentration of 100mg per 5ml. It is indicated for the treatment of various bacterial infections, including acute otitis media, pharyngitis, tonsillitis, uncomplicated urinary tract infections, and uncomplicated gonorrhea caused by susceptible strains. Cefixime exerts its bactericidal effect by inhibiting bacterial cell wall synthesis, leading to cell lysis and death. The oral suspension formulation is particularly suitable for pediatric patients or individuals who have difficulty swallowing tablets. Omnicef-O demonstrates a broad spectrum of activity against Gram-positive and Gram-negative organisms, including Streptococcus pneumoniae, Haemophilus influenzae, and Escherichia coli. The recommended dosage and duration of therapy should be determined by the severity of infection and patient-specific factors such as age and renal function. Common adverse effects may include gastrointestinal disturbances such as diarrhea, nausea, and abdominal pain. Hypersensitivity reactions, although rare, require immediate medical attention. It is essential to complete the full prescribed course to prevent the development of antibiotic resistance. Omnicef-O should be stored at controlled room temperature and shaken well before each use to ensure uniform suspension.
