Boxed warning for Azstarys

Azstarys has a boxed warning for the risk of misuse and addiction. A boxed warning is the most serious warning from the Food and Drug Administration (FDA).

Risk of misuse and addiction. Azstarys has a risk of misuse. Misuse means a drug is taken in a way other than how it’s prescribed. 

Misusing any stimulant, including Azstarys, can cause serious side effects, overdose, and death. It can also lead to addiction. Addiction means taking a drug even if it’s causing harm.

These risks increase with higher doses of Azstarys, or when the drug is used in a way it’s not approved to be used, such as snorting or injecting it. Due to these risks, your doctor will prescribe the lowest effective dosage of Azstarys and will monitor how you’re doing during treatment. Tell your doctor if you have any concerns about misuse or addiction.

Be sure to store Azstarys in a safe, locked, place. Do not share Azstarys with anyone else. Dispose of any unused or expired Azstarys safely.
