🩺 Clinical
Methylphenidate is used to control symptoms of attention deficit hyperactivity disorder (ADHD; condition that makes it hard to pay attention, control your behavior, and remain still or quiet) and to treat narcolepsy (condition that causes people to be very sleepy during the day and to fall asleep suddenly). Methylphenidate is in a class of medications called central nervous system (CNS) stimulants. It works by changing the amounts of certain natural substances in the brain.

⚠️ Warnings and Cautions ▾
5. WARNINGS AND PRECAUTIONS SECTION
5.1Abuse, Misuse, and Addiction Methylphenidate hydrochloride oral solution has a high potential for abuse and misuse. The use of methylphenidate hydrochloride oral solution exposes individuals to the risks of abuse and misuse, which can lead to the development of a substance use disorder, including addiction. Methylphenidate hydrochloride oral solution can be diverted for non-medical use into illicit channels or distribution [see Drug Abuse and Dependence (9.2)].
Misuse and abuse of CNS stimulants, including methylphenidate hydrochloride oral solution, can result in overdose and death [see Overdosage (10)], and this risk is increased with higher doses or unapproved methods of administration, such as snorting or injection. Before prescribing methylphenidate hydrochloride oral solution, assess each patient’s risk for abuse, misuse, and addiction. Educate patients and their families about these risks and proper disposal of any unused drug.
Advise patients to store methylphenidate hydrochloride oral solution in a safe place, preferably locked, and instruct patients to not give methylphenidate hydrochloride oral solution to anyone else. Throughout methylphenidate hydrochloride oral solution treatment, reassess each patient’s risk of abuse, misuse, and addiction and frequently monitor for signs and symptoms of abuse, misuse, and addiction.
5.2Risks to Patients with Serious Cardiac Disease Sudden death has been reported in patients with structural cardiac abnormalities or other serious cardiac disease who were treated with CNS stimulants at the recommended ADHD dosage. Avoid methylphenidate hydrochloride oral solution use in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrythmia, coronary artery disease, or other serious cardiac disease.
5.3Increased Blood Pressure and Heart Rate CNS stimulants cause an increase in blood pressure (mean increase approximately 2 to 4 mmHg) and heart rate (mean increase approximately 3 to 6 bpm). Some patients may have larger increases. Monitor all methylphenidate hydrochloride oral solution-treated patients for hypertension and tachycardia.
5.4Psychiatric Adverse Reactions Exacerbation of Pre-Existing Psychosis CNS stimulants may exacerbate symptoms of behavior disturbance and thought disorder in patients with a pre-existing psychotic disorder. Induction of a Manic Episode in Patients with Bipolar Illness CNS stimulants may induce a manic or mixed mood episode in patients. Prior to initiating methylphenidate hydrochloride oral solution treatment, screen patients for risk factors for developing a manic episode (e.g., comorbid or history of depressive symptoms or a family history of suicide, bipolar disorder, or depression).
New Psychotic or Manic Symptoms CNS stimulants, at the recommended dosages, may cause psychotic or manic symptoms (e.g., hallucinations, delusional thinking, or mania) in patients without a prior history of psychotic illness or mania. In a pooled analysis of multiple short-term, placebo-controlled studies of CNS stimulants, psychotic or manic symptoms occurred in approximately 0.1% of CNS stimulant-treated patients, compared with 0% of placebo-treated patients. If such symptoms occur, consider discontinuing methylphenidate hydrochloride oral solution.
5.5Priapism Prolonged and painful erections, sometimes requiring surgical intervention, have been reported with methylphenidate use in both adult and pediatric male patients. Although priapism was not reported with methylphenidate initiation, it developed after some time on methylphenidate, often subsequent to an increase in dosage. Priapism also occurred during methylphenidate withdrawal (drug holidays or during discontinuation).
Methylphenidate hydrochloride oral solution-treated patients who develop abnormally sustained or frequent and painful erections should seek immediate medical attention.

👥 Use in Specific Populations ▾
8. USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary Published studies and post marketing reports on methylphenidate use during pregnancy have not identified a drug-associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. There may be risks to the fetus associated with the use of CNS stimulants use during pregnancy (see Clinical Considerations). No effects on morphological development were observed in embryo-fetal development studies with oral administration of methylphenidate to pregnant rats and rabbits during organogenesis at doses up to 12 and 19 times, respectively, the maximum recommended human dose (MRHD) of 60 mg/day given to adults on a mg/m2 basis.
However, spina bifida was observed in rabbits at a dose 65 times the MRHD given to adults. A decrease in pup body weight was observed in a pre- and post-natal development study with oral administration of methylphenidate to rats throughout pregnancy and lactation at doses 7 times the MRHD given to adults (see Data). The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.
All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. Clinical Considerations Fetal/Neonatal Adverse Reactions CNS stimulants, such as methylphenidate hydrochloride oral solution, can cause vasoconstriction and thereby decrease placental perfusion.
No fetal and/or neonatal adverse reactions have been reported with the use of therapeutic doses of methylphenidate during pregnancy; however, premature delivery and low birth weight infants have been reported in amphetamine-dependent mothers. Data Animal Data In embryo-fetal development studies conducted in rats and rabbits, methylphenidate was administered orally at doses of up to 75 and 200 mg/kg/day, respectively, during the period of organogenesis. Malformations (increased incidence of fetal spina bifida) were observed in rabbits at the highest dose, which is approximately 65 times the MRHD of 60 mg/day given to adults on a mg/m2 basis.
The no effect level for embryo-fetal development in rabbits was 60 mg/kg/day (19 times the MRHD given to adults on a mg/m2 basis). There was no evidence of morphological development effects in rats, although increased incidences of fetal skeletal variations were seen at the highest dose level (12 times the MRHD of 60 mg/day given to adults on a mg/m2 basis), which was also maternally toxic. The no effect level for embryo-fetal development in rats was 25 mg/kg/day (4 times the MRHD on a mg/m2 basis).
When methylphenidate was administered to rats throughout pregnancy and lactation at doses of up to 45 mg/kg/day, offspring body weight gain was decreased at the highest dose (7 times the MRHD of 60 mg/day given to adults on a mg/m2 basis), but no other effects on postnatal development were observed. The no effect level for pre- and postnatal development in rats was 15 mg/kg/day (~2 times the MRHD given to adults on a mg/m2 basis).
8.2Lactation Risk Summary Limited published literature, based on milk sampling from seven mothers reports that methylphenidate is present in human milk, which resulted in infant doses of 0.16% to 0.7% of the maternal weight -adjusted dosage and a milk/plasma ratio ranging between 1.1 and 2.7. There are no reports of adverse effects on the breastfed infant and no effects on milk production. Long-term neurodevelopmental effects on infants from stimulant exposure are unknown.
The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for methylphenidate hydrochloride oral solution and any potential adverse effects on the breastfed infant from methylphenidate hydrochloride oral solution or from the underlying maternal condition. Clinical Consideration…
🆘 Overdosage ▾
10. OVERDOSAGE SECTION Clinical Effects of Overdose Overdose of CNS stimulants is characterized by the following sympathomimetic effects: Cardiovascular effects including tachyarrhythmias, and hypertension or hypotension. Vasospasm, myocardial infarction, or aortic dissection may precipitate sudden cardiac death.
Takotsubo cardiomyopathy may develop. CNS effects including psychomotor agitation, confusion, and hallucinations. Serotonin syndrome, seizures, cerebral vascular accidents, and coma may occur.
Life-threatening hyperthermia (temperatures greater than 104°F) and rhabdomyolysis may develop. Overdose Management Consider the possibility of multiple drug ingestion. Because methylphenidate has a large volume of distribution and is rapidly metabolized, dialysis is not useful.
Consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdose management recommendations.
🧬 Clinical Pharmacology ▾
12. CLINICAL PHARMACOLOGY
12.1Mechanism of Action Methylphenidate hydrochloride is a central nervous system (CNS) stimulant. The mode of therapeutic action in ADHD is not known.
12.2Pharmacodynamics Methylphenidate is a racemic mixture comprised of the d- and l-threo enantiomers. The d-threo enantiomer is more pharmacologically active than the l-threo enantiomer. Methylphenidate blocks the reuptake of norepinephrine and dopamine into the presynaptic neuron and increases the release of these monoamines into the extraneuronal space.
Cardiac Electrophysiology A formal QT study has not been conducted in subjects taking methylphenidate hydrochloride oral solution. The effect of dexmethylphenidate, the pharmacologically active d-enantiomer of methylphenidate hydrochloride oral solution, on the QT interval was evaluated in a double-blind, placebo- and open-label active (moxifloxacin)-controlled study following single doses of 40 mg dexmethylphenidate hydrochloride extended-release capsule in 75 healthy volunteers. Electrocardiograms were collected up to 12 hours postdose.
Frederica’s method for heart rate correction was employed to derive the corrected QT interval (QTcF). The maximum mean prolongation of QTcF intervals was less than 5 ms, and the upper limit of the 90% confidence interval was below 10 ms for all time-matched comparisons versus placebo. This was below the threshold of clinical concern and there was no evident exposure response relationship.
12.3Pharmacokinetics Absorption Following a single dose administration of 20 mg methylphenidate hydrochloride oral solution and 20 mg tablet of methylphenidate hydrochloride in healthy volunteers under fasted conditions, time to peak plasma concentration (Tmax) of methylphenidate was at 1 to 2 hours after dosing, and: The mean peak plasma concentration (Cmax) of methylphenidate was 9.1 ng/mL and 9.8 ng/mL, respectively. The mean area under concentration curve (AUC) of methylphenidate was 46.7 hour*ng/mL and 50.0 hour*ng/mL, respectively.
Effect of Food Ingestion of a high-fat meal with methylphenidate hydrochloride oral solution increased methylphenidate mean Cmax and AUC by about 13% and 25%, respectively. Time to Cmax (Tmax) was delayed by approximately 1 hour. Distribution Plasma protein binding is 10% to 33%.
The volume of distribution was 2.65 ±
1.11L/kg for d-methylphenidate and 1.80 ±
0.91L/kg for l-methylphenidate. Elimination The mean terminal half-life (t½) of methylphenidate was 2.7 hours following administration of 20 mg methylphenidate hydrochloride oral solution. The systemic clearance is 0.40 ±
0.12L/h/kg for d-methylphenidate and 0.73 ±
0.28L/h/kg for l-methylphenidate. Metabolism Methylphenidate is metabolized primarily by deesterification to alpha-phenyl-piperidine acetic acid (ritalinic acid), which has little or no pharmacologic activity. Excretion After oral dosing of radiolabeled methylphenidate in humans, about 90% of the radioactivity was recovered in urine.
The main urinary metabolite was ritalinic acid, accounting for approximately 80% of the dose. Specific Populations Male and Female Patients, Racial Groups, and Age The effect of gender, race, and age on the pharmacokinetics of methylphenidate after methylphenidate hydrochloride oral solution administration have not been studied. Patients with Renal Impairment Methylphenidate hydrochloride oral solution has not been studied in patients with renal impairment.
Since renal clearance is not an important route of methylphenidate clearance, renal impairment is expected to have little effect on the pharmacokinetics of methylphenidate hydrochloride oral solution. Patients with Hepatic Impairment Methylphenidate hydrochloride oral solution has not been studied in patients with hepatic impairment. Since methylphenidate is metabolized primarily to ritalinic acid by nonmicrosomal hydrolytic esterases that are widely distributed throughout the body, hepatic impairment is expected to have minimal effect on the p…
