Pre-treatment Screening

Prior to treating patients with ADZENYS XR-ODT, assess for the presence of cardiac disease (i.e., perform a careful history, family history of sudden death or ventricular arrhythmia, and physical exam) [see Warnings and Precautions (5.2)].

Assess the risk of abuse prior to prescribing, and monitor for signs of abuse and dependence while on therapy. Maintain careful prescription records, educate patients about abuse, monitor for signs of abuse and overdose, and periodically re-evaluate the need for ADZENYS XR-ODT use [see Warnings and Precautions (5.1), and Drug Abuse and Dependence (9)].

Dosing Considerations for All Patients

ADZENYS XR-ODT may be taken with or without food. Individualize the dosage according to the therapeutic needs and response of the patient.

ADZENYS XR-ODT should be taken as follows:

  • The tablet should remain in the blister pack until the patient is ready to take it.
  • The patient or caregiver should use dry hands to open the blister.
  • Tear along the perforation, bend the blister where indicated and peel back the blister's labeled backing to take out the tablet. The tablet should not be pushed through the foil.
  • As soon as the blister is opened, the tablet should be removed and placed on the patient's tongue.
  • The whole tablet should be placed on the tongue and allowed to disintegrate without chewing or crushing.
  • The tablet will disintegrate in saliva so that it can be swallowed.

Pediatric Patients

The recommended starting dosage is 6.3 mg once daily in the morning. Increase in increments of 3.1 mg or 6.3 mg at weekly intervals. The maximum recommended dose is 18.8 mg daily for patients 6 to 12 years, and 12.5 mg daily for patients 13 to 17 years [see Use in Specific Populations (8.3), Clinical Studies (14)].


The recommended dose is ADZENYS XR-ODT 12.5 mg daily.

Switching from Other Amphetamine Products

Patients taking ADDERALL XR may be switched to ADZENYS XR-ODT at the equivalent dose taken once daily [see Clinical Pharmacology (12.3)]. Refer to Table 1 for equivalent doses of ADZENYS XR-ODT and ADDERALL XR. ADDERALL XR (dextroamphetamine sulfate, dextroamphetamine saccharate, amphetamine aspartate monohydrate, and amphetamine sulfate extended-release capsules) is also referred to as mixed salts of a single-entity amphetamine product extended-release capsules (MAS ER).

Table 1: Equivalent Doses of ADZENYS XR-ODT and ADDERALL XR (Mixed Salts of a Single-Entity Amphetamine Product) Extended-Release Capsules
Amphetamine extended-release orally disintegrating tablets
3.1 mg 6.3 mg 9.4 mg 12.5 mg 15.7 mg 18.8 mg
Mixed salts of a single-entity amphetamine product extended-release capsules (MAS ER)
5 mg 10 mg 15 mg 20 mg 25 mg 30 mg

If switching from any other amphetamine products, discontinue that treatment, and titrate with ADZENYS XR-ODT using the titration schedule [ see Dosage and Administration (2.3), (2.4)].

Do not substitute for other amphetamine products on a milligram-per-milligram basis because of different amphetamine base compositions and differing pharmacokinetic profiles [see Warnings and Precautions (5.7)].

Dosage Modifications Due to Drug Interactions

Agents that alter urinary pH can impact urinary excretion and alter blood levels of amphetamine. Acidifying agents (e.g., ascorbic acid) decrease blood levels, while alkalinizing agents (e.g., sodium bicarbonate) increase blood levels. Adjust ADZENYS XR-ODT dosage accordingly [see Drug Interactions (7.1)].
