Methylphenidate for ADHD rejected from the WHO Essential Medicines List due to uncertainties in benefit-harm profile
Open accessAbstract
Attention deficit hyperactivity disorder (ADHD) is a common psychiatric disorder with estimated global prevalence rates between 3% and 5% in children and 2.5% in adults, depending on the classification system used. The psychostimulant methylphenidate is one of the most frequently used medications for ADHD. In this analysis article we describe shortly the evidence in the field, an application for inclusion of methylphenidate on the WHO Model List of Essential Medicines, the comments raised to the application and the WHO Expert Committee’s decision. The application of getting methylphenidate on the WHO list was overzealous in reporting potential benefits, without highlighting key uncertainties and harms. Decisions encompassing medicines candidate to the WHO Model List should not be based on speculation about potential benefits and should fully incorporate areas of uncertainties. Even though methylphenidate has been used for over 60 years, the evidence concerning the benefits of this medication in children, adolescents and adults with ADHD is uncertain. The decision of the committee was to not include methylphenidate in the WHO Model List of Essential Medicines ‘due to uncertainties in the estimates of benefit, and concerns regarding the quality and limitations of the available evidence for both benefit and harm’.

“As a result, clinicians often approach the prescription of psychostimulants with caution, concerned about the potential for worsening substance use outcomes and the risk of mis-use [69,71].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
