Stimulant medications can cause a spike in blood pressure and all patients taking stimulant medications should have their blood pressure monitored to make sure increases in blood pressure are not causing additional health problems.


Methylphenidate can increase agitation and nervousness in patients, and therefore, people with pre-existing psychiatric conditions should be monitored and, if needed, stimulant medication treatment should be discontinued. Some psychiatric conditions, which may worsen with methylphenidate use, include: anxiety, bipolar disorder, depression and other mood disorders. For people with bipolar disorder, special care should be taken as stimulant medication can cause a mixed or manic episode.

Stimulant medications have not been shown to cause aggression or increase aggressive tendencies, however, care should be taken to monitor possible complications.
