What is the primary treatment for acute bacterial sinusitis?

The primary treatment for acute bacterial sinusitis is antibiotic therapy. This is due to the nature of acute bacterial sinusitis, which typically arises from an infection caused by bacteria following a viral upper respiratory infection. Antibiotic therapy is essential because it targets the bacteria causing the infection, helping to reduce symptoms, eliminate the pathogen, and prevent complications.

In cases where symptoms persist beyond a certain period or worsen despite initial management, antibiotics can significantly improve recovery time and alleviate discomfort. While supportive care such as hydration is important, especially in helping the body recover, it does not directly combat the underlying bacterial infection.

Antihistamines may be useful in managing allergic rhinitis or minor sinus congestion but do not address the bacterial aspect of acute sinusitis. Surgical drainage is generally reserved for complicated cases where there is an abscess or significant obstruction that does not respond to medical management. Hence, antibiotic therapy is the most effective initial approach in treating acute bacterial sinusitis.
