Which treatment should be avoided in children with acute sinusitis?

In the context of treating acute sinusitis in children, the use of antihistamines is generally advised against, primarily due to their potential side effects and the lack of evidence supporting their effectiveness in this specific condition. Antihistamines can dry up mucous membranes, potentially leading to thicker secretions, which may worsen sinus drainage and prolong symptoms. Additionally, they can cause sedation and other adverse effects, particularly in younger patients.

On the other hand, decongestants and saline nasal sprays are often considered appropriate for relieving symptoms of acute sinusitis, as they can help reduce nasal congestion and improve drainage. Antibiotics are typically reserved for cases where a bacterial infection is suspected or confirmed, especially if symptoms are severe or persistent, but they should be used judiciously. Thus, it is the use of antihistamines that is discouraged in the management of acute sinusitis in children, making this choice the most appropriate regarding treatment in this scenario.
