Boxed warning for Mydayis

Mydayis has a boxed warning for the risk of misuse and addiction. A boxed warning is the most serious warning from the FDA.

Mydayis is classified as a Schedule II controlled substance in the United States. A controlled substance is a drug the government regulates due to the risk of dependence or misuse. This means doctors and pharmacists must follow strict rules when prescribing and dispensing Mydayis. These rules are in place to help reduce the risk of misuse and addiction.

Mydayis has a high risk of misuse. Misuse means taking a drug in a way other than how it’s prescribed.

Misusing a stimulant, such as Mydayis, can cause serious side effects, overdose, and possibly death. It can also lead to addiction. Addiction means taking a drug even if it’s causing harm. Doctors sometimes refer to misuse and addiction as a substance use disorder.

These risks increase with higher doses of Mydayis and with misuse of the medication, such as through snorting or injection. Due to these risks, your doctor will prescribe the lowest effective dosage of Mydayis and will monitor how you’re doing during treatment. Tell your doctor if you have any concerns about misuse.

Be sure to store Mydayis in a safe, preferably locked place. Do not share Mydayis with anyone else. Make sure you dispose of any unused or expired Mydayis safely.

You can talk with your doctor or pharmacist to learn more about these risks.
