Treatment for Infectious Mononucleosis (Mono): Options, Medications & Outlook
Evidence-based Infectious Mononucleosis (Mono) treatment: first-line medications, monitoring targets, escalation criteria, and long-term clinical outlook.
Updated March 27, 2026
Treatment for Infectious Mononucleosis (Mono) focuses on eradicating the causative organism, resolving infection, and preventing complications or recurrence. Infectious mononucleosis, caused by Epstein-Barr virus, presents with severe fatigue, sore throat, swollen lymph nodes, and splenomegaly. It primarily affects adolescents and young adults; strenuous activity must be avoided due to spleen rupture risk.
Clinical Context
The primary approach involves targeted antimicrobial, antiviral, antifungal, or antiparasitic therapy guided by culture and sensitivity results. Monitoring typically includes clinical response, temperature, inflammatory markers (CRP, WBC), and culture clearance. Treatment intensity is tailored to disease severity, patient comorbidities, and response. Guideline-directed therapy reduces the risk of complications, hospitalisation, and disease progression.
