1 interaction related to ritalin
Methylphenidate treats ADHD by inhibiting reuptake of dopamine and norepinephrine. St. John's Wort adds its own monoamine reuptake activity and is a strong inducer of the CYP3A4 drug-metabolising enzyme. A small published observation suggests St. John's Wort can blunt methylphenidate's effect on ADHD symptoms. There is also a theoretical, additive serotonergic risk, mainly relevant if other serotonergic drugs are present, but no confirmed serotonin syndrome cases have been reported for this specific pair.
