Selling or giving away Zenzedi may harm others and is against the law.
WARNING: ABUSE, MISUSE, AND ADDICTION
Dextroamphetamine sulfate 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 dextroamphetamine sulfate, can result in overdose and death, and this risk is
increased with higher doses or unapproved methods of administration, such as snorting or
injection.
Before prescribing dextroamphetamine sulfate, 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 dextroamphetamine sulfate treatment, reassess
each patient’s risk of abuse, misuse, and addiction and frequently monitor for signs and symptoms
of abuse, misuse, and addiction.
Do not take Zenzedi if you or your child:
- are allergic to amphetamine products or any of the ingredients in Zenzedi.
- are taking or have taken within the past 14 days, a medicine used to treat depression called a
monoamine oxidase inhibitor (MAOI), including the antibiotic linezolid or the intravenous
medicine methylene blue.
