Methylin Side Effects

Note: This document contains side effect information about methylphenidate. Some of the dosage forms listed on this page may not apply to the brand name Methylin.

For the Consumer

Applies to methylphenidate: oral capsule extended release, oral powder for suspension extended release, oral solution, oral tablet, oral tablet chewable, oral tablet extended release, oral tablet extended release chewable, oral tablet extended release disintegrating

Other dosage forms:

Warning

Oral route (Tablet, Extended Release, Disintegrating)

CNS stimulants, including methylphenidate extended-release orally disintegrating tablets, other methylphenidate-containing products, and amphetamines, have a high potential for abuse and dependence. Assess the risk of abuse prior to prescribing, and monitor for signs of abuse and dependence while on therapy.

Oral route (Capsule, Extended Release; Tablet; Tablet, Extended Release)

Use cautiously in emotionally unstable patients, such as those with a history of drug dependence or alcoholism, because of abuse potential. Chronic abuse can lead to marked tolerance and psychic dependence with varying degrees of abnormal behavior, including psychotic episodes. Careful supervision is required during drug withdrawal, since severe depression as well as the effects of chronic overactivity can be unmasked.

Oral route (Powder for Suspension, Extended Release; Tablet, Extended Release Chewable)

CNS stimulants, including methylphenidate hydrochloride, other methylphenidate-containing products, and amphetamines, have a high potential for abuse and dependence. Assess the risk of abuse prior to prescribing, and monitor for signs of abuse and dependence while on therapy

Oral route (Tablet, Chewable; Solution)

Use caution when prescribing to patients with a history of drug dependence or alcoholism. Chronic abusive use can lead to marked tolerance and psychological dependence with abnormal behavior. Psychotic episodes can occur, especially with parenteral abuse. Carefully supervise withdrawal from abusive use to avoid the onset of severe depression. Follow-up may be required following withdrawal from chronic therapeutic use, as symptoms of the underlying disorder may emerge.
