Supportive Care Recommendations for Pediatric Acute Sinusitis and Conjunctivitis

Core Supportive Measures

Rest and hydration – Adequate rest and fluid intake support the immune response and maintain mucosal function in children with acute sinusitis. (American Academy of Pediatrics guideline) 1, 2
Analgesics as needed – Acetaminophen or ibuprofen can be used for pain relief, headache, and fever control. (American Academy of Pediatrics guideline) 1, 2
Warm facial compresses – Applying warm packs to the sinus areas reduces discomfort and promotes drainage. (American Academy of Pediatrics guideline) 1, 2
Steamy showers – Inhalation of steam helps loosen secretions and improves nasal drainage. (American Academy of Pediatrics guideline) 1
Head‑of‑bed elevation – Sleeping with the head of the bed elevated facilitates sinus drainage and lessens congestion. (American Academy of Pediatrics guideline) 1, 2

Smoke and pollution avoidance – Eliminating exposure to cigarette smoke and outdoor air pollution is recommended to prevent symptom worsening. (American Academy of Pediatrics guideline) 1, 2
Allergen avoidance – When allergic rhinitis contributes to sinusitis, known allergens should be avoided. (American Academy of Pediatrics guideline) 1, 2

Severe headache or high fever (≥ 39 °C) – Worsening symptoms, especially severe headache or high fever, warrant prompt provider contact. (American Academy of Pediatrics guideline) 1, 2
No improvement within 3–5 days – Lack of clinical improvement after 3–5 days of supportive care should trigger evaluation. (American Academy of Pediatrics guideline) 1, 2
Orbital complications – New eye swelling, proptosis, or impaired eye movement suggest orbital involvement and need urgent assessment. (American Academy of Pediatrics) 3
Intracranial complications – Altered mental status or severe headache raises concern for intracranial spread and requires immediate evaluation. (American Academy of Pediatrics) 3

Routine decongestants, antihistamines, or mucolytics – These agents are not recommended for acute bacterial sinusitis because evidence of benefit is limited. (American Academy of Pediatrics guideline) 4, 3
Unnecessary imaging – Plain radiographs, CT, or MRI are not indicated in uncomplicated acute bacterial sinusitis; they do not alter management and expose the child to radiation. (American Academy of Pediatrics guideline) 4, 5, 6

The American Academy of Pediatrics recommends treatment with amoxicillin-clavulanate for 10-14 days, or until the patient is symptom-free for 7 consecutive days, for a child with uncomplicated bacterial sinusitis 7
The American Academy of Pediatrics recommends a high dose of amoxicillin-clavulanate, 80-90 mg/kg/day (amoxicillin component) with 6.4 mg/kg/day of clavulanate, divided into 2 daily doses, with a maximum of 2 grams per dose, for a child with uncomplicated bacterial sinusitis 7, 8
For a 35 kg child, this translates to approximately 2,800-3,150 mg/day of amoxicillin, divided into two doses 7

The American Academy of Pediatrics establishes that treatment should continue for 10-14 days or until the patient is symptom-free for 7 days, resulting in a minimum of 10 days of therapy, to prevent relapse and ensure complete eradication of bacterial pathogens 7, 9
This duration is necessary to prevent relapse and ensure complete eradication of bacterial pathogens, such as Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis 7

The American Academy of Pediatrics recommends reevaluating the child after 72 hours (3 days) of treatment 7, 9
If there is no improvement or if symptoms worsen, consider changing to a second-line antibiotic, reevaluating the diagnosis, or investigating complications 7, 10

Never use azithromycin for bacterial sinusitis in children due to resistance rates of 20-25% for S. pneumoniae and H. influenzae 7, 9
Do not interrupt treatment prematurely, even if the child improves after 5-7 days, as this increases the risk of relapse 7, 9
Do not use first-generation cephalosporins (cefalexin) as they do not adequately cover H. influenzae 7, 9

The American Academy of Pediatrics recommends intranasal corticosteroids (mometasone, fluticasone) twice a day to reduce mucosal inflammation 9
Irrigation with saline solution for symptomatic relief 7, 9
Analgesics (paracetamol, ibuprofen) for pain and fever 9
Adequate hydration and warm facial compresses 9

Lack of improvement after 7 days of appropriate second-line antibiotic therapy 9
Recurrent sinusitis (≥3 episodes per year) 9
Suspected orbital complications (proptosis, eyelid edema, limited extraocular movements) or central nervous system complications (severe headache, photophobia, seizures) 7, 10
