Other important side effects of methylphenidate include:

There have been rare reports of Tourette's syndrome, a syndrome in which there are uncontrollable tics such as grimacing occurring with methylphenidate use. Because of the potential for side effects, methylphenidate should be used with caution by patients who have relatives with Tourette's syndrome or have the syndrome themselves or who have severe anxiety, seizures, psychosis, emotional instability, major depression, glaucoma, or motor tics.

Sudden discontinuation of long-term methylphenidate therapy may unmask depression. Gradual withdrawal, under supervision, is recommended.

Methylphenidate is habit forming and should be used cautiously in individuals with a history of drug or alcohol abuse. Chronic abuse can lead to tolerance and psychological dependence leading to abnormal behavior.

Priapism defined as painful and nonpainful penile erection lasting more than 4 hours, have been reported in pediatric and adult patients treated with stimulants. The erection usually resolves when the drug is stopped. Prompt medical attention is required in the event of suspected priapism.
