Treatment Plan Assessment for Influenza A with Allergic Conditions

Influenza A Management

• The American College of Physicians and Infectious Diseases Society of America recommend oseltamivir 75 mg PO twice daily × 5 days for influenza A treatment when initiated within 48 hours of symptom onset, reducing illness duration by approximately 24 hours and decreasing hospitalization rates and secondary complications 2, 3
• Monitoring for worsening symptoms, such as shortness of breath, high fever, chest pain, and unstable clinical factors like respiratory rate >24/min, oxygen saturation <90%, or inability to maintain oral intake, is essential 2, 5, 4
• Dose adjustment to 75 mg once daily is required if creatinine clearance is <30 ml/min, as recommended by the Infectious Diseases Society of America 2, 3, 6

Allergic Rhinitis and Conjunctivitis Management

• The American Academy of Allergy, Asthma, and Immunology recommends allergen avoidance and saline nasal spray PRN as appropriate adjunctive measures for allergic rhinitis management 1
• The American Academy of Allergy, Asthma, and Immunology suggests that ketotifen eye drops 1 drop both eyes twice daily is an excellent choice for allergic conjunctivitis, providing rapid onset and suitable for both acute and long-term treatment 1
• Cold compresses PRN are appropriate supportive measures for allergic conjunctivitis, as recommended by the American Academy of Allergy, Asthma, and Immunology 1

Antibiotic Consideration

• The Infectious Diseases Society of America recommends that antibiotics are NOT indicated at this time for previously well adults with acute bronchitis complicating influenza, in the absence of pneumonia 2, 5, 4
• Consider antibiotics only if the patient develops worsening symptoms, such as recrudescent fever or increasing dyspnea, or shows evidence of bacterial pneumonia, as recommended by the Infectious Diseases Society of America 2, 4
