Efficacy and safety of modafinil versus dexamethasone in cancer-related fatigue: a prospective randomized controlled study

The aim of this study was to compare the efficacy and safety of modafinil and dexamethasone in the management of cancer-related fatigue and their effects on quality of life (QoL). A prospective randomized controlled study was conducted, enrolling 80 cancer patients experiencing moderate or severe fatigue following at least three cycles of chemotherapy or a course of palliative/curative radiotherapy. Patients received either oral modafinil 100 mg or dexamethasone 4 mg daily for 14 days. Levels of fatigue, QoL and symptom severity were compared after 14–21 days. Both drugs were efficacious and safe in the management of fatigue and QoL. However, modafinil performed marginally better. Although modafinil demonstrated marginal superiority, both modafinil and dexamethasone can improve fatigue and QoL in cancer patients.
