ABSTRACT
Introduction. Methotrexate (MTX) is an essential drug in the
treatment of acute lymphoblastic leukemia (ALLL). Like all
other drugs, its use is not without potential adverse effects such
as neurotoxicity (NT). In addition to the inherent risk of the
drug, concomitant use of certain substances may increase serum
MTX concentrations, which increases the risk of developing NT.
Reducing vitamin B12 levels is one of the mechanisms involved
in NT development. It has been reported in the literature that
dextromethorphan (DXM) is a useful drug for reversing this
adverse effect.
Clinical case: We report a case of a 10-year-old female with high
risk ALL who presents subacute MTX NT data two weeks after
receiving high dose MTX consolidation therapy; NT was reversed
within 12 hours of initiating DXM.
Conclusion. A quick retrieval of the NT frame by MTX was
obtained after the administration of DXM, as reported in literature.
Therefore, DXM treatment can be considered as a therapeutic
option for subacute NT by MTX. MTX NT is a rare condition in
this group of patients, so this publication is expected to contribute
to the spread of NT and its treatment, as well as to lead to future
research.
