This is the interactions section of this product’s FDA label — what the manufacturer documented for this drug. It is not a check of your medication list, and a drug missing from it has not been cleared: licensed clinical databases list far more interactions than any single label does. Before combining medicines, ask a pharmacist, who can check everything you take at once and will do it for free.

Drug interactions

7.1 Drugs Having
Clinically Important Interactions with Amphetamines Table 5: Drugs having clinically important interactions with amphetamines. MAO Inhibitors (MAOI) Clinical Impact MAOI antidepressants slow amphetamine metabolism, increasing amphetamines effect on the release of norepinephrine and other monoamines from adrenergic nerve endings causing headaches and other signs of hypertensive crisis. Toxic neurological effects and malignant hyperpyrexia can occur, sometimes with fatal results. Intervention Do not administer ADZENYS XR-ODT during or within 14 days following the administration of MAOI. Serotonergic Drugs Clinical Impact The concomitant use of ADZENYS XR-ODT and serotonergic drugs increases the risk of serotonin syndrome. Intervention Initiate with lower doses and monitor patients for signs and symptoms of serotonin syndrome, particularly during ADZENYS XR-ODT initiation or dosage increase. If serotonin syndrome occurs, discontinue ADZENYS XR-ODT and the concomitant serotonergic drug(s). Alkalinizing Agents Clinical Impact Increase blood levels and potentiate the action of amphetamine. Intervention Co-administration of ADZENYS XR-ODT and gastrointestinal alkalinizing agents should be avoided. Acidifying Agents Clinical Impact Lower blood levels and efficacy of amphetamines. Intervention Increase dose based on clinical response. Tricyclic Antidepressants Clinical Impact May enhance the activity of tricyclic or sympathomimetic agents causing striking and sustained increases in the concentration of d-amphetamine in the brain; cardiovascular effects can be potentiated. Intervention Monitor frequently and adjust or use alternative therapy based on clinical response.
7.2 Drug/Laboratory
