In acute sinusitis, which statement about antibiotic duration is correct?

• A. A 5-day course of high-dose amoxicillin is as efficacious as longer courses
• B. The course should be continued for a minimum of 7 days after resolution of symptoms
• C. Clindamycin is the drug of choice in children with PCN allergy
• D. Decongestants are recommended as adjunctive therapy

Answer: (B)

The main idea is that completing an adequate antibiotic course for pediatric acute sinusitis is important to fully eradicate the infection and prevent relapse. The statement that you should continue the antibiotic for a minimum of seven days after the symptoms have resolved reflects this goal of ensuring complete bacterial clearance, even after you start to see improvement. In practice, this means planning a total course that is long enough—often about 7–10 days in children—and then prioritizing finishing a defined post-symptom period to solidify the response. Shorter courses, such as five days, are generally not considered sufficient for many pediatric cases. For allergy to penicillin, clindamycin isn’t the preferred first-line choice because of limited activity against common sinusitis pathogens and resistance concerns. Decongestants, while sometimes used for comfort, are not proven to improve outcomes in acute bacterial sinusitis and are not the primary therapy.
