Focef O 100mg Tablet contains Cefixime 100mg, a third-generation cephalosporin antibiotic used to treat a variety of bacterial infections. It works by inhibiting the synthesis of the bacterial cell wall, leading to the destruction of susceptible bacteria. This medication is effective against infections caused by gram-positive and gram-negative bacteria, including respiratory tract infections such as bronchitis and pneumonia, urinary tract infections, otitis media, and uncomplicated gonorrhea. Focef O is typically prescribed when oral antibiotic therapy is appropriate, offering good bioavailability and convenient dosing. It is important to complete the full course of treatment as prescribed, even if symptoms improve earlier, to prevent the development of antibiotic resistance. Common side effects may include gastrointestinal disturbances such as diarrhea, nausea, abdominal pain, and mild allergic reactions like rash or itching. Patients with a history of hypersensitivity to cephalosporins or penicillins should inform their healthcare provider before use. Focef O should be used cautiously in individuals with renal impairment, and dosage adjustments may be necessary. Always consult a healthcare professional before starting this medication to ensure it is appropriate for your condition and to discuss potential drug interactions and contraindications.
