Scientists identify methylphenidate as an effective tool for combating chronic cancer related fatigue

A new meta-analysis in the May 2026 issue of JNCCN-Journal of the National Comprehensive Cancer Network provides updated evidence that methylphenidate-type psychostimulants-a class of medication that increases dopamine and norepinephrine availability in the brain-can provide meaningful relief for cancer-related fatigue.

Cancer-related fatigue affects nearly three-quarters of people living with cancer, according to some estimates, yet it remains one of the most undertreated symptoms in oncology.

According to the findings, the use of the prescription medications methylphenidate (MPH) or dexmethylphenidate (d-MPH) was associated with significant improvements in fatigue scores across widely validated scales relative to placebo. Those effects were shown to increase over time.

Bruno Almeida Costa, MD, Study Lead Author and Fellow, The University of Texas MD Anderson Cancer CenterWhat makes this finding particularly noteworthy is the time dimension: the benefit isn't fully apparent in the first couple of weeks, but by around five weeks it reaches a level that genuinely matters in terms of patients' daily energy and function."

For people dealing with a symptom that can be profoundly disabling, that is a meaningful contribution. I would encourage cancer care professionals to think of methylphenidate as one piece of a broader approach to managing fatigue, not as a standalone solution. The strongest evidence still belongs to exercise, cognitive-behavioral therapy, and mind-body practices. But those take time-often 8 to 12 weeks of consistent engagement-to reach their full benefit. Methylphenidate could serve as a bridge during that window, providing earlier relief while the longer-term strategies take effect."

Results were based on nine different double-blind, individually randomized, parallel-group, placebo-controlled, phase II/III trials evaluating either MPH or d-MPH in adults with advanced cancer or actively receiving cancer-directed treatment. There were 823 total patients included. The studies were published between May 2006 and July 2024 and primarily rated fatigue using the FACIT-F scale, consisting of a 13-item patient-reported questionnaire.

The authors point out that MPH has one of the "longest-standing and best-documented safety records among actively prescribed controlled substances." It has been on the market since 1955 and is approved for use in patients as young as 6 years old for ADHD and narcolepsy. The analysis found no statistically significant increase in side effects compared with placebo, though careful patient selection and regular monitoring remain important.

Dr. Costa added: "We are seeing a worrying trend of cancer diagnoses in younger adults who are building careers, raising families, and leading very active lives. For this population, fatigue can be especially disruptive because there's so much they need and want to do. Our findings show that a well-established, accessible medication can provide meaningful relief within weeks, giving clinicians a practical tool to help preserve daily functioning and support engagement with other treatments."
