Why to Avoid Ritalin®
A
Schedule II Substance
Ritalin Side
Effects
from the Physicians' Desk Reference®
RITALIN-SR® methylphenidate hydrochloride USP sustained-release tablets.
WARNINGS - Ritalin should not be used in children
under six years, since safety and efficacy in this age group have not
been established. Sufficient data on safety and efficacy of long-term
use of Ritalin in children are not yet available. Although a causal relationship
has not been established, suppression of growth (ie, weight gain, and/or
height) has been reported with the long-term use of stimulants in children.
Therefore, patients requiring long-term therapy should be carefully monitored.
ADVERSE REACTIONS
Nervousness and insomnia are the most common adverse reactions but
are usually controlled by reducing dosage and omitting the drug in the
afternoon or evening. 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; dizzines; palpitations;
headache; dyskinesia; drowsiness; 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: leukopenia and/or anemia; a few
instances of scalp hair loss. In children, loss of appetite, abdominal
pain, weight loss during prolonged therapy, insomnia, and tachycardia
may occur more frequently; however, any of the other adverse reactions
listed above may also occur.
DRUG DEPENDENCE
Ritalin should be given cautiously to emotionally unstable patients, such
as those with a history of drug dependence or alcoholism, because such
patients may increase dosage on their own initiative. Chronically abusive
use can lead to marked tolerance and psychic dependence with varying degrees
of abnormal behavior. Frank psychotic episodes can occur, especially with
parental abuse. Careful supervision is required during drug withdrawal,
since severe depression as well as the effects of chronic over activity
can be unmasked. Long-term follow-up may be required because of the patient's
basic personality disturbances.
