Does clarithromycin treat sinusitis?
Clarithromycin—a macrolide antibiotic—is commonly available in tablet, capsule, granule, and dry suspension formulations. It is indicated for infections caused by susceptible pathogenic bacteria. Clarithromycin is covered by China’s medical insurance program in the following dosage forms: tablets, granules, capsules, soft capsules, and dispersible tablets. So, can clarithromycin be used to treat sinusitis? Below, we address this question.

Can clarithromycin treat sinusitis?
Yes, clarithromycin can be used to treat sinusitis. As a commonly prescribed antibiotic, clarithromycin is primarily indicated for acute or chronic bacterial infections. Sinusitis is a relatively common bacterial inflammatory condition; therefore, clarithromycin represents a frequently adopted therapeutic option.
In addition to clarithromycin, patients with sinusitis may require adjunctive therapies. Commonly used agents include nasal sprays, oral traditional Chinese medicines, and mucolytic expectorants. Nasal irrigation with normal saline is also recommended.
Generally, follow-up visits are required after initiating treatment to assess clinical response. If standard pharmacotherapy proves ineffective, further evaluation—including sinus computed tomography (CT)—is warranted. Some patients may ultimately require surgical intervention to prevent adverse health consequences.
