Other reactions include hypersensitivity
(including skin rash, urticaria, fever, arthralgia, exfoliative dermatitis
, erythema multiforme
with histopathological findings of necrotizing vasculitis, and thrombocytopenic purpura); anorexia
; nausea; dizziness; palpitations; headache; dyskinesia
; blood pressure
and pulse changes, both up and down; tachycardia; angina
; cardiac arrhythmia
; abdominal pain
; weight loss during prolonged therapy. There have been rare reports of tourette's syndrome. Toxic psychosis has been reported. Although a definite causal relationship has not been established, the following have been reported in patients taking this drug: instances of abnormal liver function, ranging from transaminase elevation to hepatic coma
; isolated cases of cerebral arteritis and/or occlusion; leukopenia and/or anemia; transient depressed mood
; aggressive behavior; a few instances of scalp hair loss. Very rare reports of neuroleptic malignant syndrome
(nms) have been received, and, in most of these, patients were concurrently receiving therapies associated with nms. In a single report, a ten-year-old boy who had been taking methylphenidate for approximately 18 months experienced an nms-like event within 45 minutes of ingesting his first dose of venlafaxine. It is uncertain whether this case represented a drug-drug interaction, a response to either drug alone, or some other cause.
in short, there aer a barrage of side effects. I think the minimalist approach to medications is most ideal. Unless you absolutely require a medication to improve symptoms, they are best avoided. In general, however, most side effects are reduced with time. They are most prominent when a medication is first initiated. I have never seen motor tics with ritalin, but I have seen nervousness, insomnia, and decreased appetite
. Hope this helps.
