These factors may affect how you should use this medication.
Behaviour or mood changes: People taking this medication have reported agitation, hallucinations, symptoms of depression, and thoughts of self-harm. If you experience these types of symptoms while taking mixed salts amphetamine, contact your doctor immediately.
Bipolar disorder: This medication may trigger a mixed or manic episode for people with bipolar disorder. If you have a history of bipolar disorder, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed. Tell your doctor of any new or worsening mental problems while taking this medication.

If you have a history of seizures, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Exercise: Strenuous exercise may increase the risk of heart problems for people taking mixed salts amphetamine. People participating in strenuous exercise or activities should consult their doctor before taking mixed salts amphetamine extended release.

This medication should generally not be used by people with known structural heart abnormalities, such as abnormal size, missing or poorly functioning heart valves, or problems with blood vessels connected to the heart.

If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Mental health: Stimulant medications such as mixed salts amphetamine extended release appear to make behaviour and thought disturbances worse for people who have psychotic conditions.

If you experience symptoms such as hallucinations, mania (feeling unusually over-excited or uninhibited), or delusional thinking, or notice them in a family member who is taking this medication, contact your doctor as soon as possible.
If you have a history of psychosis or other mental illness such as depression, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Suicidal or agitated behaviour: People taking this medication may feel agitated (restless, anxious, aggressive, emotional, and feeling not like themselves), or they may want to hurt themselves or others.

However, this has been reported for children who use stimulants such as mixed salts amphetamine over long periods of time. Children who need long-term treatment should be carefully monitored for growth. Their doctor may also recommend a "drug holiday," where the medication is not given on weekends or during school holidays.

If you have Tourette's syndrome or develop tics while on this medication, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Vision problems: Difficulties with vision such as blurring of vision have been reported with stimulant use. If this problem persists, talk to your doctor.
