Interactions between your selected drugs

fluoxetine ⇔ methylphenidate

Applies to: Prozac (fluoxetine) and Concerta (methylphenidate)

MONITOR: The coadministration with methylphenidate may increase the plasma concentrations of selective serotonin reuptake inhibitors (SSRIs). According to the manufacturer, human pharmacologic studies have shown that methylphenidate may inhibit the metabolism of SSRIs, and there have been reports that methylphenidate augments the clinical response to SSRIs.

MANAGEMENT: Pharmacologic response to SSRIs should be monitored more closely whenever methylphenidate (racemic) or dexmethylphenidate (the more pharmacologically active d-enantiomer) is added to or withdrawn from therapy, and the SSRI dosage adjusted as necessary.
