The most commonly prescribed treatment for people who have a sinus infection, antibiotics, is usually stronger than needed, according to a study conducted by researchers.
The standard amoxicillin is as effective as the stronger combination of amoxicillin-clavulanate in treating sinus infections, a report published in the Journal of the American Medical Association on April 18 revealed.
The use of antibiotics is highest among patients with sinus infections, but there is no consensus on which antibiotic is most effective against uncomplicated cases, scientists noted.

With nearly 5 million antibiotic prescriptions for adults with acute sinusitis in the United States each year, the findings have the potential to impact existing treatment practices substantially. The Cleveland Clinic experts found no benefit to amoxicillin-clavulanate, supporting standard-dose amoxicillin as the preferred antibiotic for adults with uncomplicated acute sinusitis.
Amoxicillin is a beta-lactam antibiotic belonging to the penicillin class that can be used to treat various bacterial infections.
The clavulanate compound inhibits an enzyme that allows bacteria to become resistant to amoxicillin. However, some bacteria that cause sinus infections do not contain the enzyme.
Amoxicillin and amoxicillin-clavulanate account for about 45% of all antibiotics prescribed for acute sinusitis; hence, it is imperative to determine the best choice between them.
In this latest study, insurance claims for over 521,000 adults with acute sinusitis from 2018 to 2023 were analyzed. All patients were treated with daily doses of either amoxicillin or amoxicillin-clavulanate.
According to results, both drugs exhibited similar failure rates; 3.1% for amoxicillin and 3% for amoxicillin-clavulanate. Experts recommend combination therapy for immunocompromised individuals; however, no differences in failure rates have been observed between patients in either case.
Moreover, the risk of developing other infections is higher with amoxicillin-clavulanate than with a single antibiotic.
