Infectious mononucleosis (glandular fever) is associated with fatigue, fever, sore throat and swollen lymph nodes. The severity of symptoms can vary. In extreme cases, throat swelling can cause breathing difficulties and other complications requiring hospitalisation. The duration of symptoms is variable and can last for months. Few treatments are available and there are no universal criteria for using steroids in glandular fever. While steroids are generally reserved for severe complications, there are reports of practitioners treating symptomatic people with steroids. Infectious mononucleosis often affects young people at a time in their education where they need to be continually productive and the potential long duration of the condition is perhaps a key factor in prescribing such a potent drug for symptom control.
