From the FDA label for Concerta (application NDA021121). Other methylphenidate products — different forms, different strengths — are dosed differently. Follow the label for the one you were prescribed.
Prior to initiating CONCERTA treatment assess for ( 2.1 ): the presence of cardiac disease for family history of tics or Tourette' syndrome and clinically evaluate patients for motor or verbal tics or Tourette's syndrome Administer once daily in the morning with or without food. Swallow whole with liquids; do not chew, divide, or crush. ( 2.2 ) Recommended dosage in pediatric patients 6 to 17 years of age new to methylphenidate: starting dosage is18 mg once daily. May be increased weekly in 18 mg increments. Maximum dosage for pediatric patients ( 2.3 ): 6 to 12 years: 54 mg once daily 13 to 17 years: 72 mg once daily Recommended dosage in adults (up to 65 years of age) new to methylphenidate: starting dosage is 18 mg or 36 mg once daily. May be increased weekly in 18 mg increments, up to 72 mg once daily. ( 2.3 ) Patients currently using immediate-release methylphenidate: starting CONCERTA dosage is based on current dosage regimen. ( 2.4 ) 2.1 Pretreatment Screening Prior to treating patients with CONCERTA, assess: For the presence of cardiac disease (e.g., perform a careful history, family history of sudden death or ventricular arrhythmia, and physical exam) [see Warnings and Precautions (5.2) ].

Every methylphenidate product we track (14)
Same active ingredient — different manufacturer, form, price and FDA recall record. That last one is what our independent score measures.
The elimination half-life of methylphenidate is about 2.7 hours. This is the terminal elimination half-life of immediate-release methylphenidate in adults; the main metabolite (ritalinic acid) has little or no activity and does not extend the drug's action. Extended-release brands like Concerta and Ritalin LA don't change the molecule's true half-life — they only release it slowly, so their longer apparent duration comes from the delivery system, not slower elimination.
Half-life is how long the body takes to clear half a dose. It is not the same as how long a drug test can detect it, and it varies with age, kidney and liver function.
Frequently asked questions
What is methylphenidate?
CONCERTA ® is a central nervous system (CNS) stimulant. CONCERTA is available in four strengths. Each extended-release tablet for oral administration contains 18, 27, 36, or 54 mg of methylphenidate hydrochloride, USP. Chemically, methylphenidate hydrochloride is d,l (racemic) methyl α-phenyl-2-piperidineacetate hydrochloride, its empirical formula is C 14 H 19 NO 2 ∙HCl, and its structural formula is: Methylphenidate hydrochloride, USP is a white, odorless crystalline powder. Its solutions are acid to litmus. It is freely soluble in water and in methanol, soluble in alcohol, and slightly soluble in chloroform and in acetone. Its molecular weight is 269.77. CONCERTA also contains the following inactive ingredients: butylated hydroxytoluene, carnauba wax, cellulose acetate, hypromellose, lactose, phosphoric acid, poloxamer, polyethylene glycol, polyethylene oxides, povidone, propylene glycol, sodium chloride, stearic acid, succinic acid, synthetic iron oxides, titanium dioxide, and triacetin. It is possible that CONCERTA extended-release tablets may be visible on abdominal x-rays under certain circumstances, especially when digital enhancing techniques are utilized. Chemical Structure
What kind of drug is methylphenidate?
The FDA classifies methylphenidate as a central nervous system stimulant. CNS stimulants raise the levels of the brain's signaling chemicals dopamine and norepinephrine, either by releasing more of them or by blocking their reuptake. This heightened activity in attention and arousal circuits increases alertness, energy, and focus. If you are checking whether it is safe to combine with something else, the class is what matters — two drugs from the same class usually should not be stacked.
How long does methylphenidate stay in your system?
The elimination half-life of methylphenidate is about 2.7 hours — that is how long the body takes to clear half of a dose. This is the terminal elimination half-life of immediate-release methylphenidate in adults; the main metabolite (ritalinic acid) has little or no activity and does not extend the drug's action. Extended-release brands like Concerta and Ritalin LA don't change the molecule's true half-life — they only release it slowly, so their longer apparent duration comes from the delivery system, not slower elimination. Half-life is not the same as how long a drug test can detect the drug, and it varies with age, kidney and liver function.

Who shouldn’t take methylphenidate
CONCERTA is contraindicated in patients: Known to be hypersensitive to methylphenidate or other components of CONCERTA. Hypersensitivity reactions, such as angioedema and anaphylactic reactions, have been reported in patients treated with CONCERTA. [see Adverse Reactions (6) ] . Receiving concomitant monoamine oxidase inhibitors (MAOIs), and within 14 days following discontinuation of treatment with a MAO inhibitor because of the risk of a hypertensive crisis [see Drug Interactions (7) ] .

Methylphenidate drug interactions
Table 6 describes clinically significant drug interactions with CONCERTA. Table 6: Clinically Significant Drug Interactions Monoamine Oxidase Inhibitors Prevention or Management Concomitant use of CNS stimulants, including CONCERTA, with MAOIs or within 14 days after discontinuing an MAOI is contraindicated [ see Contraindications (4) ]. Mechanism and Clinical Effect(s) Concomitant use of MAOIs and CNS stimulants, including CONCERTA, can cause hypertensive crisis.

Risperidone Prevention or Management Monitor for signs of extrapyramidal symptoms. Mechanism and Clinical Effect(s) The risk of risperidone-associated…
Can you take methylphenidate with other medicines?
It depends on the medicine. We check it against the FDA labels rather than guessing: our interaction checker searches each drug's own label for the other and quotes what it says, naming the section it came from. Run methylphenidate against whatever else you take — and remember that a label not naming a drug is not the same as that combination being safe.
What brand names is methylphenidate sold under?
We track 14 methylphenidate-containing products in the U.S.: Concerta, Relexxii, Methylin, Ritalin-SR, Ritalin La, Ritalin, Daytrana and Aptensio XR, and 6 more. They are the same active ingredient; they differ in form, manufacturer, price and FDA recall record.
What forms does methylphenidate come in?
Across the brands we track, methylphenidate is currently marketed as tablet, extended release, solution, capsule, extended release, tablet, patch, tablet, orally disintegrating, capsule, tablet, chewable, tablet, chewable, extended release and suspension, extended release, per the FDA's National Drug Code Directory. Each form is dosed differently — follow the label for the exact product you were prescribed.
Is there a generic methylphenidate?
Yes. Our catalog lists 1 generic methylphenidate product alongside the brand versions. A generic has the same active ingredient and must meet the FDA's bioequivalence standard; it usually costs less. Ask your pharmacist which one your plan covers.
Has methylphenidate been recalled?
The FDA's Enforcement database lists 2 recall records whose product description mentions methylphenidate. The most recent: Focalin XR (dexmethylphenidate HCl) 5 mg (Jun 1, 2026). A recall applies to specific lots, not to the drug as a whole — check the record for the affected lot numbers.
