Additions and/or revisions underlined These italics usually appear at the beginning of the section. In some cases, italics may be an inherent part of the label, and will most often appear in the body of the section. |
| Underlines | Any text that is underlined indicates text that has been added or revised. There are exceptions where underlining occurs in a section subtitle or heading. This is the case when there is just one word underlined in the body of the text. |
Sections

| PCI/PI/MG | Patient Counseling Information (PLR format only) - summarizes the information that a health care provider should convey to a patient (or caregiver when applicable) when a counseling discussion is taking place (e.g., a physician prescribing a drug during an office visit, a nurse providing discharge instructions at a hospital, or a pharmacist conveying information at a pharmacy). Patient Information - FDA approved patient labeling. Medication Guide - paper handouts that come with many prescription medicines. The guides address issues that are specific to particular drugs and drug classes, and they contain FDA-approved information that can help patients avoid serious adverse events. |
Only NDAs and CDER regulated BLAs are included in this database. ANDAs are not included.
Applications that remain active, even if the product has been discontinued, undergo safety-related labeling changes.
RELEXXII (NDA-216117)
(METHYLPHENIDATE HYDROCHLORIDE)
Safety-related Labeling Changes Approved by FDA Center for Drug Evaluation and Research (CDER)
09/23/2025 (SUPPL-3)
10/13/2023 (SUPPL-1)
Boxed Warning
Additions and/or revisions underlined:
WARNING: ABUSE, MISUSE, AND ADDICTION
RELEXXII has a high potential for abuse and misuse, which can lead to the development of a substance use disorder, including addiction. Misuse and abuse of CNS stimulants, including RELEXXII, 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 RELEXXII, assess each patient’s risk for abuse, misuse, and addiction. Educate patients and their families about these risks, proper storage of the drug, and proper disposal of any unused drug. Throughout RELEXXII treatment, reassess each patient’s risk of abuse, misuse, and addiction and frequently monitor for signs and symptoms of abuse, misuse, and addiction [see Warnings and Precautions (5.1) and Drug Abuse and Dependence (9.2)].
5 Warnings and Precautions
5.1 Abuse, Misuse, and Addiction
Additions and/or revisions underlined:
RELEXXII has a high potential for abuse and misuse. The use of RELEXXII exposes individuals to the risks of abuse and misuse, which can lead to the development of a substance use disorder, including addiction. RELEXXII can be diverted for non-medical use into illicit channels or distribution [see Drug Abuse and Dependence (9.2, 9.3)].
Misuse and abuse of CNS stimulants, including RELEXXII, 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 RELEXXII, 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 RELEXXII in a safe place, preferably locked, and instruct patients to not give RELEXXII to anyone else. Throughout RELEXXII treatment, reassess each patient’s risk of abuse, misuse, and addiction and frequently monitor for signs and symptoms of abuse, misuse, and addiction.
5.9 Acute Angle Closure Glaucoma
New subsection added:
There have been reports of angle closure glaucoma associated with methylphenidate treatment. Although the mechanism is not clear, RELEXXII-treated patients considered at risk for acute angle closure glaucoma (e.g., patients with significant hyperopia) should be evaluated by an ophthalmologist.
5.10 Increased Intraocular Pressure and Glaucoma
New subsection added:
There have been reports of an elevation of intraocular pressure (IOP) associated with methylphenidate treatment [see Adverse Reactions (6.2)].
Prescribe RELEXXII to patients with open-angle glaucoma or abnormally increased IOP only if the benefit of treatment is considered to outweigh the risk. Closely monitor RELEXXII-treated patients with a history of abnormally increased IOP or open angle glaucoma.
5.11 Motor and Verbal Tics, and Worsening of Tourette’s Syndrome
New subsection added:
CNS stimulants, including methylphenidate, have been associated with the onset or exacerbation of motor and verbal tics. Worsening of Tourette’s syndrome has also been reported [see Adverse Reactions (6.2)].
Before initiating RELEXXII, assess the family history and clinically evaluate patients for tics or Tourette’s syndrome. Regularly monitor RELEXXII-treated patients for the emergence or worsening of tics or Tourette’s syndrome, and discontinue treatment if clinically appropriate.
6 Adverse Reactions
Additions and/or revisions underlined:
The following are discussed in more detail in other sections of the labeling:
Abuse, Misuse, and Addiction [see Box Warning, Warnings and Precautions (5.1), and Drug Abuse and Dependence(9.2, 9.3)]
…
Acute Angle Closure Glaucoma [see Warnings and Precautions (5.9)]
Increased Intraocular Pressure and Glaucoma [see Warnings and Precautions (5.10)]
Motor and Verbal Tics, and Worsening of Tourette’s Syndrome [see Warnings and Precautions (5.11)]
6.2 Postmarketing Experience
Additions and/or revisions underlined:
…
Diplopia, Increased intraocular pressure, Mydriasis, Visual impairment
…
Nervous System Disorders: Convulsion, Grand mal convulsion, Dyskinesia, Serotonin syndrome in combination with serotonergic drugs, Motor and Verbal Tics
…
17 PCI/PI/MG (Patient Counseling Information/Patient Information/Medication Guide)
PATIENT COUNSELING INFORMATION
Additions and/or revisions underlined:
…
Abuse, Misuse, and Addiction
Educate patients and their families about the risks of abuse, misuse, and addiction of RELEXXII, which can lead to overdose and death, and proper disposal of any unused drug [see Warnings and Precautions (5.1), Drug Abuse and Dependence (9.2), and Overdosage (10)].Advise patients to store RELEXXII in a safe place, preferably locked, and instruct patients to not give RELEXXII to anyone else.
…
Suppression of Growth in Pediatric Patients
Advise patients, families and caregivers that RELEXXII may cause slowing of growth and weight loss [see Warnings and Precautions (5.7)].
Increased Intraocular Pressure (IOP) and Glaucoma
Advise patients that IOP and glaucoma may occur during treatment with RELEXXII [see Warnings and Precautions (5.10)].
Motor and Verbal Tics, and Worsening of Tourette’s Syndrome
Advise patients that motor and verbal tics and worsening of Tourette’s Syndrome may occur during treatment with RELEXXII. Instruct patients to notify their healthcare provider if emergence of new tics or worsening of tics or Tourette’s syndrome occurs [see Warnings and Precautions (5.11].
