There is no role of 2 antibiotics in Typhoid. Only one antibiotics is required either Azithromycin or cefixime . Dose is correct cefixime 400 mg and Azithromycin 1 gm But duration must be 14 days if diagnosis of Typhoid is correctly made clinically and by lab test. If there is a doubt in Typhoid Diagnosis 7 day treatment is sufficient. No scientific proof for using two antibiotics

Yes above doses for 7days is enough,if clinical improvement is there.
