Boxed warning
WARNING: ABUSE, MISUSE, AND ADDICTION AZSTARYS 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 AZSTARYS, 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 AZSTARYS, 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 AZSTARYS 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 )].

AZSTARYS 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 AZSTARYS, can result in overdose and death ( 5.1 , 9.2 , 10 ): Before prescribing AZSTARYS, assess each patient’s risk for abuse, misuse, and addiction.

Dosing in kidney impairment
This label has no separate kidney-impairment dosing section. Check warnings and clinical pharmacology in the full label.
Preparation and administration
Administration Instructions Administer AZSTARYS orally once daily in the morning with or without food [see Clinical Pharmacology] . AZSTARYS capsules may be taken whole, or opened and the entire contents sprinkled into 50 mL of water or over 2 tablespoons of applesauce. Consume all the drug/food mixture immediately or within 10 minutes of mixing; do not store for future use [see Clinical Pharmacology] .
Drug interactions
Check serdexmethylphenidate chloride and dexmethylphenidate against a medication listLabel text (4 paragraphs)
Antihypertensive Drugs: Monitor blood pressure. Adjust dosage of antihypertensive drug as needed. ( 7.1 )
7.1 Clinically Important Interactions with AZSTARYS Table 1 presents clinically important drug interactions with AZSTARYS. Table 1: Clinically Important Drug Interactions with AZSTARYS Monoamine Oxidase Inhibitors (MAOIs) Clinical Impact Concomitant use of MAOIs and CNS stimulants, including AZSTARYS, 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 AZSTARYS concomitantly with MAOIs or within 14 days after discontinuing MAOI treatment [see Contraindications ( 4 )] Antihypertensive Drugs Clinical Impact AZSTARYS 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 AZSTARYS may increase the risk of sudden blood pressure and heart rate increase during surgery. Intervention Avoid use of AZSTARYS 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.
Contraindications
4 CONTRAINDICATIONS AZSTARYS is contraindicated in patients: with known hypersensitivity to serdexmethylphenidate, methylphenidate, or other components of AZSTARYS. Bronchospasm, rash, and pruritus have been reported in patients who received AZSTARYS. 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), or within 14 days following discontinuation of treatment with an MAOI, because of the risk of hypertensive crisis [see Drug Interactions ( 7.1 )] .
Known hypersensitivity to serdexmethylphenidate, methylphenidate, or product components. ( 4 ) Concurrent treatment with a monoamine oxidase inhibitor (MAOI), or use of an MAOI within the preceding 14 days. ( 4 )
Pregnancy and lactation
Pregnancy
8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to ADHD medications, including AZSTARYS, during pregnancy. Healthcare providers are encouraged to register patients by calling the National Pregnancy Registry for Psychostimulants at 1-866-961-2388. Risk Summary There are no available data on AZSTARYS use in pregnant women to evaluate for a drug- associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes; however, AZSTARYS contains dexmethylphenidate and serdexmethylphenidate, a prodrug of dexmethylphenidate.
Dexmethylphenidate is the d-threo enantiomer of racemic methylphenidate. Published studies and postmarketing 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 ). Embryo-fetal development studies in rats showed delayed fetal skeletal ossification at doses up to 3 times the maximum recommended human dose (MRHD) of 40 mg/day dexmethylphenidate hydrochloride given to adults based on plasma levels.
A decrease in pup weight in males was observed in a pre- and post-natal development study with oral administration of dexmethylphenidate to rats throughout pregnancy and lactation at doses 3 times the MRHD of 40 mg/day dexmethylphenidate hydrochloride given to adults based on plasma levels ( see Data ). No evidence of developmental effects were found in an embryo-fetal development study with oral administration of serdexmethylphenidate to rabbits during organogenesis at doses up to approximately 49 times the MRHD of 52 mg/day serdexmethylphenidate given to adults based on plasma levels ( 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 AZSTARYS, 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…
