Is Ritalin a controlled substance? Its methylphenidate is Schedule II.
The federal schedule listing, its CFR citation and DEA code number, and the statutory criteria, quoted from the eCFR and the U.S. Code.
Yes. Methylphenidate is listed in Schedule II at 21 CFR 1308.12(d)(4) with DEA Controlled Substances Code Number 1724. "Ritalin" is a brand name and does not appear in the schedule text; the listing is for the substance. A related compound, serdexmethylphenidate, is separately listed in Schedule IV at 21 CFR 1308.14(f)(11), code 1729.

The short answer
Yes. Methylphenidate is listed in Schedule II at 21 CFR 1308.12(d)(4) with DEA Controlled Substances Code Number 1724. "Ritalin" is a brand name and does not appear in the schedule text; the listing is for the substance. A related compound, serdexmethylphenidate, is separately listed in Schedule IV at 21 CFR 1308.14(f)(11), code 1729.
The statute behind every schedule is Title 21 U.S.C. 812, part of the Controlled Substances Act. The regulation that lists substances one by one is 21 CFR part 1308, sections 1308.11 to 1308.15. This page quotes both. The CFR text was read from the eCFR versioner API for the issue current through October 29, 2026, and the statute from the 2024 U.S. Code edition published on govinfo. This is a classification page only: it contains no dosing, use, acquisition or synthesis information.
The methylphenidate entry, quoted
In the Schedule II section, paragraph (d) "Stimulants" lists five substances. Item (4) is "Methylphenidate 1724". Unlike the amphetamine entry next to it, the methylphenidate line in the eCFR text does not spell out salts and isomers, but the paragraph's lead-in applies to "any material, compound, mixture, or preparation which contains any quantity of the following substances". The statute's initial Schedule II list in 21 U.S.C. 812(c) also names methylphenidate, ending its stimulant paragraph with "(4) Methylphenidate."
The five entries read: (1) Amphetamine, its salts, optical isomers, and salts of its optical isomers 1100; (2) Methamphetamine, its salts, isomers, and salts of its isomers 1105; (3) Phenmetrazine and its salts 1631; (4) Methylphenidate 1724; (5) Lisdexamfetamine, its salts, isomers, and salts of its isomers 1205.
A different schedule for a related name
It is easy to assume that anything with "methylphenidate" in its name shares one schedule, and the CFR shows that is not so. Section 1308.14(f), the Schedule IV "Stimulants" paragraph, includes item (11) "Serdexmethylphenidate 1729". It is a separate entry with its own code and its own schedule. The two names must be read exactly as the CFR prints them, which is why this page quotes the line rather than paraphrasing it. The full Schedule IV stimulants paragraph lists: (1) Cathine 1230; (2) Diethylpropion 1610; (3) Fencamfamin 1760; (4) Fenproporex 1575; (5) Mazindol 1605; (6) Mefenorex 1580; (7) Modafinil 1680; (8) Pemoline 1530; (9) Phentermine 1640; (10) Pipradrol 1750; (11) Serdexmethylphenidate 1729; (12) Sibutramine 1675; (13) Solriamfetol 1650; (14) SPA 1635.
Brand names versus substances
Section 1308.12(a) says the schedule covers substances "by whatever official name, common or usual name, chemical name, or brand name designated, listed in this section". The section in fact lists chemical or official names and a text search of 1308.11 to 1308.15 for "Ritalin" finds nothing. The brand-to-ingredient pairing used in the headline of this page comes from common usage, not from the CFR, and a specific product's ingredients are stated on its FDA-approved label (see FDA's DailyMed). This page gives no dosing, use, obtaining or prescribing information.
The Schedule II listing, in the CFR's own words
The lead-in of 21 CFR 1308.12(d) reads:
(d) Stimulants. Unless specifically excepted or unless listed in another schedule, any material, compound, mixture, or preparation which contains any quantity of the following substances having a stimulant effect on the central nervous system:
Entries from Schedule II stimulants at 1308.12(d):
- (1) Amphetamine, its salts, optical isomers, and salts of its optical isomers 1100
- (2) Methamphetamine, its salts, isomers, and salts of its isomers 1105
- (3) Phenmetrazine and its salts 1631
- (4) Methylphenidate 1724
- (5) Lisdexamfetamine, its salts, isomers, and salts of its isomers 1205
What the statute requires for Schedule II
Title 21 U.S.C. 812(b) says a drug or other substance "may not be placed in any schedule unless the findings required for such schedule are made". For Schedule II the findings are: (A) The drug or other substance has a high potential for abuse. (B) The drug or other substance has a currently accepted medical use in treatment in the United States or a currently accepted medical use with severe restrictions. (C) Abuse of the drug or other substances may lead to severe psychological or physical dependence.
Those findings are the statutory test for putting a substance into the schedule. They are not a description of any person's use of a drug, and they are not a medical statement. The CFR sections 1308.11 to 1308.15 then list, substance by substance, what has been placed in each of the five schedules.
How to read and re-check a schedule listing
A schedule entry has a fixed shape. A lead-in sentence says which class of substance follows and often that the listing extends to salts, isomers and salts of isomers. Each line then names a substance and, in most sections, a four-digit DEA Controlled Substances Code Number. The opening paragraph of 1308.11 to 1308.14 says each substance "has been assigned the DEA Controlled Substances Code Number set forth opposite it". The number identifies the line; it is not a rating of risk.
- Open the section for the schedule you want: 21 CFR 1308.11 (Schedule I), 1308.12 (II), 1308.13 (III), 1308.14 (IV) or 1308.15 (V) in the eCFR.
- Find the paragraph for the class of substance: opiates, opium derivatives, hallucinogenic substances, depressants, stimulants, narcotic drugs, anabolic steroids and so on, each introduced by a lead-in sentence.
- Read the entry by its official or chemical name, not by brand name, and note the four-digit DEA Controlled Substances Code Number printed beside it.
- Check for words such as "unless specifically excepted" or "except" in the lead-in or the line itself, which limit what the entry covers.
- Confirm the date: the eCFR shows an "as of" date, and the schedules change by rulemaking.
