Cefixime is a third generation cephalosporin and is usually taken for 5-7 days as a course of treatment, while the duration of treatment may vary depending on the condition and site of infection. Cefixime has a strong antibacterial ability and a wide antibacterial range, mainly by blocking bacterial cell wall synthesis, thus causing bacteria to die in a low osmotic pressure environment. Most common infections generally require 5-7 days of cefixime, such as cholecystitis, and a full dosage and course of treatment is required to see significant results. In the case of mild infections, only 3-5 days of cefixime is needed, while severe infections, such as lung abscesses and sinusitis, require 7-14 days of cefixime to achieve efficacy. The use of antibiotics must be in sufficient quantity and duration to avoid failure to achieve efficacy and development of drug-resistant bacteria. It is forbidden to drink alcohol while taking Cefixime and within 3 days after stopping it because cephalosporins can produce disulfiram-like reactions with alcohol, which can be life-threatening in serious cases.
