FDA Boxed Warning (the FDA’s most serious warning)
Boxed (black-box) warning — from the FDA label
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 )] . WARNING: ABUSE, MISUSE, AND ADDICTION See full prescribing information for complete boxed warning. 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 ( 5.1 , 9.2 , 10 ): Before prescribing RELEXXII, assess each patient’s risk for abuse, misuse, and addiction.

Warnings
Important safety information
Risks to Patients with Serious Cardiac Disease: Avoid use in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrhythmias, coronary artery disease, or serious cardiac disease. ( 5.2 ) Increased Blood Pressure and Heart Rate: Monitor blood pressure and pulse. ( 5.3 ) Psychiatric Adverse Reactions: Prior to initiating RELEXXII, screen patients for risk factors for developing a manic episode. If new psychotic or manic symptoms occur, consider discontinuing RELEXXII. ( 5.4 ) Priapism: If abnormally sustained or frequent and painful erections occur, patients should seek immediate medical attention. ( 5.5 ) Peripheral Vasculopathy, including Raynaud’s Phenomenon: Careful observation for digital changes is necessary during RELEXXII treatment. Further clinical evaluation (e.g., rheumatology referral) may be appropriate for patients who develop signs or symptoms of peripheral vasculopathy. ( 5.6 ) Long-Term Suppression of Growth in Pediatric Patients: Closely monitor growth (height and weight) in pediatric patients. Pediatric patients not growing or gaining weight as expected may need to have their treatment interrupted. ( 5.7 ) Gastrointestinal Obstruction: Avoid use with preexisting GI narrowing. ( 5.8 ) Acute Angle Closure Glaucoma: RELEXXII-treated patients considered at risk for acute angle closure glaucoma (e.g., patients with significant hyperopia) should be evaluated by an ophthalmologist. ( 5.9 ) Increased Intraocular Pressure (IOP) and Glaucoma: 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 patients with a history of increased IOP or open angle glaucoma. ( 5.10 ) Motor and Verbal Tics, and Worsening of Tourette’s Syndrome: Before initiating RELEXXII, assess the family history and clinically evaluate patients for tics or Tourette’s syndrome. Regularly monitor patients for the emergence or worsening of tics or Tourette’s syndrome. Discontinue treatment if clinically appropriate. ( 5.11 ) 5.1 Abuse, Misuse, and Addiction 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. 5.2 Risks to Patients with Serious Cardiac Disease Sudden death has been reported in patients with structural cardiac abnormalities or other serious cardiac disease who were taking CNS stimulants at the recommended ADHD dosage. Avoid RELEXXII use in patients with known structural cardiac abnormalities, cardiomyopathy, serious cardiac arrhythmia, coronary artery disease, or other serious cardiac disease. 5.3 Increased Blood Pressure and Heart Rate CNS stimulants cause an increase in blood pressure (mean increase approximately 2 to 4 mm Hg) and heart rate (mean increase approximately 3 to 6 bpm) [see Adverse Reactions ( 6.1 )]. Some patients may have larger increases. Monitor all RELEXXII-treated patients for hypertension and tachycardia. 5.4 Psychiatric Adverse Reactions Exacerbation of Pre-existing Psychosis CNS stimulants may exacerbate symptoms of behavior disturbance and thought disorder in patients with a preexisting psychotic disorder. Induction of a Manic Episode in Patients with Bipolar Disorder CNS stimulants may induce a manic or mixed episode in patients. Prior to initiating RELEXXII treatment, screen patients for risk factors for developing a manic episode (e.g., comorbid or history of depressive symptoms, a family history of suicide, bipolar disorder, and depression). New Psychotic or Manic Symptoms CNS stimulants, at the recommended dosage, 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 to 0% of placebo-treated patients. If such symptoms occur, consider discontinuing RELEXXII. 5.5 Priapism Prolonged and painful erections, sometimes requiring surgical intervention, have been reported with methylphenidate use, including another formulation of methylphenidate hydrochloride extended-release tablets, in both adult and pediatric male patients [see Adverse Reactions ( 6.2 )] . 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 a methylphenidate withdrawal (drug holidays or during discontinuation). RELEXXII-treated patients who develop abnormally sustained or frequent and painful erections should seek immediate medical attention. 5.6 Peripheral Vasculopathy, including Raynaud’s Phenomenon CNS stimulants, such as RELEXXII, used to treat ADHD are associated with peripheral vasculopathy, including Raynaud’s phenomenon. Signs and symptoms are usually intermittent and mild; however, sequelae have included digital ulceration and/or soft tissue breakdown. Effects of peripheral vasculopathy, including Raynaud’s phenomenon, were observed in post-marketing reports and at the therapeutic dosage in all age groups throughout the course of treatment. Signs and symptoms generally improved after reduction or discontinuation of the CNS stimulant. Careful observation for digital changes is necessary during RELEXXII treatment. Further clinical evaluation (e.g., rheumatology referral) may be appropriate for RELEXXII-treated patients who develop signs or symptoms of peripheral vasculopathy. 5.7 Long-Term Suppression of Growth in Pediatric Patients RELEXXII is not approved for use and is not recommended in pediatric patients below 6 years of age [see Use in Specific Populations ( 8.4 )] . CNS stimulants have been associated with weight loss and slowing of growth rate in pediatric patients. Careful follow-up of weight and height in pediatric patients ages 7 to 10 years who were randomized to either methylphenidate or nonmedication treatment groups over 14 months, as well as in naturalistic subgroups of newly methylphenidate-treated and nonmedication-treated pediatric patients over 36 months (to the ages of 10 to 13 years), suggests that pediatric patients who received methylphenidate for 7 days per week throughout the year had a temporary slowing in growth rate (on average, a total of about 2 cm less growth in height and 2.7 kg less growth in weight over 3 years), without evidence of growth rebound during this development period. Closely monitor growth (weight and height) in RELEXXII-treated pediatric patients. Pediatric patients who are not growing or gaining height or weight as expected may need to have their treatment interrupted. 5.8 Potential for Gastrointestinal Obstruction Because the RELEXXII tablet is nondeformable and does not appreciably change in shape in the GI tract, RELEXXII should not ordinarily be administered to patients with preexisting severe gastrointestinal narrowing (pathologic or iatrogenic, for…
Who should not take Relexxii
RELEXXII is contraindicated in patients: with a known hypersensitivity to methylphenidate or other components of RELEXXII. Hypersensitivity reactions such as angioedema and anaphylactic reactions have been reported in patients treated with other methylphenidate products [see Adverse Reactions ( 6.2 )] . receiving concomitant treatment with monoamine oxidase inhibitors (MAOIs), and also within 14 days following discontinuation of treatment with a MAOI, because of the risk of hypertensive crisis [see Drug Interactions ( 7.1 )] . Known hypersensitivity to methylphenidate or other components of RELEXXII ( 4 ) Concurrent treatment with a monoamine oxidase inhibitor (MAOI), or use of an MAOI within the preceding 14 days ( 4 )
Overdose — what happens if you take too much
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. The pharmacokinetic profile of RELEXXII should be considered when treating patients with overdose. 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.

Interactions
Antihypertensive Drugs: Monitor blood pressure. Adjust dosage of antihypertensive drug as needed ( 7.1 ) 7.1 Clinically Important Drug Interactions Table 6 presents clinically important drug interactions with RELEXXII. Table 6: Drugs Having Clinically Important Interactions with RELEXXII Monoamine Oxidase Inhibitors (MAOI) Clinical Impact: Concomitant use of MAOIs and CNS stimulants can cause hypertensive crisis. Potential outcomes include death, stroke, myocardial infarction, aortic dissection, ophthalmological complications, eclampsia, pulmonary edema, and renal failure [see Contraindications ( 4 )] . Intervention: Do not administer RELEXXII concomitantly with MAOIs or within 14 days after discontinuing MAOI treatment. Antihypertensive Drugs Clinical Impact: RELEXXII may decrease the effectiveness of drugs used to treat hypertension [see Warnings and Precautions ( 5.3 )] . Intervention: Monitor blood pressure and adjust the dosage of the antihypertensive drug as needed. Halogenated Anesthetics Clinical Impact: Concomitant use of halogenated anesthetics and RELEXXII may increase the risk of sudden blood pressure and heart rate increase during surgery. Intervention: Avoid use of RELEXXII in patients being treated with anesthetics on the day of surgery. Risperidone Clinical Impact: Combined use of methylphenidate with risperidone when there is a change, whether an increase or decrease, in dosage of either or both medications, may increase the risk of extrapyramidal symptoms (EPS). Intervention: Monitor for signs of EPS.
How long does Methylphenidate Hydrochloride stay in your body?
The elimination half-life of methylphenidate hydrochloride is about 2.7 hours — the time it takes the body to clear about half of it. As a rule of thumb, a medicine is mostly gone after roughly 4 to 5 half-lives, though this varies from person to person with age and kidney or liver function. 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.

Frequently asked questions
- What does Relexxii treat?
- Relexxii (Methylphenidate Hydrochloride) may be used to treat attention deficit disorder with hyperactivity, depressive disorder, narcolepsy, based on NIH RxClass drug-classification data (conditions a drug may treat — not a verbatim copy of the FDA-approved label). This is general reference, not medical advice.
- How does Relexxii work?
- Relexxii is 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.
- How is Relexxii rated?
- pharmaranks gives Relexxii a composite score of 3.5 out of 5, currently based on 1 weighted source (FDA regulatory recall-safety data weighted highest). See our methodology at /how-we-rate.
- How much does Relexxii cost?
- Nobody can tell you what you will pay — your price is set by your insurer's formulary, your deductible and the pharmacy's markup, and none of those are published.
