Concerta Drug Interactions - What Every Concerta User Must Know


Courtesy of the FDA

Because of possible effects on blood pressure, CONCERTA® should be used cautiously with pressor agents.

Human pharmacologic studies have shown that methylphenidate may inhibit the metabolism of coumarin anticoagulants, anticonvulsants (eg, phenobarbital, phenytoin, primidone), and some antidepressants (tricyclics and selective serotonin reuptake inhibitors). Downward dose adjustment of these drugs may be required when given concomitantly with methylphenidate. It may be necessary to adjust the dosage and monitor plasma drug concentrations (or, in the case of coumarin, coagulation times), when initiating or discontinuing concomitant methylphenidate.

Serious adverse events have been reported in concomitant use with clonidine, although no causality for the combination has been established. The safety of using methylphenidate in combination with clonidine or other centrally acting alpha-2 agonists has not been systematically evaluated.

If you or someone you know has suffered a serious Concerta side effect, you may be entitled to compensation for your pain & suffering. To find out if you have a case, fill out the form below for a free case evaluation.

Weitz & Luxenberg is no longer accepting Concerta cases.
