Can roxithromycin treat sinusitis?

Roxithromycin is generally used to treat certain types of sinusitis. It is effective against bacterial sinusitis caused by pathogens sensitive to roxithromycin, but less effective for viral sinusitis or bacterial sinusitis involving drug-resistant organisms. If in doubt, it is recommended to consult a healthcare professional in advance. Detailed analysis is as follows:

Roxithromycin is typically appropriate for bacterial sinusitis when the infecting bacteria are susceptible to this antibiotic. Such sinusitis often presents with symptoms including purulent nasal discharge, worsening nasal congestion, and headache. Roxithromycin works by inhibiting bacterial protein synthesis, thereby preventing bacterial replication and reducing inflammatory responses to alleviate discomfort. It is particularly suitable for patients allergic to penicillin antibiotics or those who cannot use other antibiotics, serving as an alternative treatment option.

Its use is not recommended in cases of viral sinusitis, as antibiotics are ineffective against viral infections. Taking roxithromycin in such cases will not relieve symptoms and may increase the risk of adverse drug effects. Additionally, if the bacteria causing bacterial sinusitis are resistant to roxithromycin, the infection may not be adequately controlled, potentially leading to prolonged or worsened illness. In these situations, another antibiotic to which the bacteria are sensitive should be used instead.

During roxithromycin treatment, it is essential to complete the full course as prescribed by a physician; do not discontinue the medication prematurely even if symptoms improve. Monitor for possible adverse reactions such as nausea, diarrhea, or rash, and promptly inform your doctor of any abnormalities.
