Stop the supplement and call a clinician immediately if new memory problems are marked, worsening, or accompanied by confusion or behavioral changes. Call 911 if confusion starts suddenly, especially with faintness, fever, headache, abnormal breathing, unconsciousness, injury, or danger to anyone. A memory problem that appears after starting a supplement does not prove the product caused it. Even so, the timing matters and deserves prompt medical attention.

When should you stop the supplement?
Stop using the product immediately if the change is serious. This includes pronounced confusion, major memory difficulty, or a marked change in thinking or behavior. The fda lists marked cognitive or behavioral changes among serious supplement reactions.
It advises consumers to stop the suspected product and seek care, even when they are unsure it caused the illness, before submitting a dietary supplement safety report. For milder but new memory trouble, contact a clinician promptly. Explain when the symptom began and how it relates to starting the supplement or changing its dose.
Which symptoms are an emergency?
Sudden confusion can signal an urgent medical problem. According to MedlinePlus guidance on confusion, call 911 when sudden confusion occurs, particularly with: Do not wait to see whether stopping the supplement makes sudden confusion disappear. If the confusion is new but not sudden, arrange a clinician appointment.
- Faintness or loss of consciousness
- Fever or headache
- Abnormal breathing
- An injury
- Risk of harm to the affected person or someone else
Did the supplement cause the problem?
The timing creates a reasonable suspicion, not proof. FDA adverse-event reports may be incomplete or unverified, and people may be using several products. These reports cannot establish how often a reaction occurs or whether a supplement caused it.
Other possible causes include prescription medicines, infections, low blood sugar, low oxygen, nutritional deficiencies, seizures, and stroke. A clinician needs to consider these possibilities instead of assuming the newest supplement is responsible. This distinction matters because stopping a suspected product may remove one risk without treating the actual cause. New confusion or memory difficulty still requires medical assessment.
What should you tell the clinician?
Prepare a complete list of everything the person takes. Include prescription medicines, nonprescription medicines, vitamins, minerals, herbs, and other supplements.
Also record: People using high doses, several supplements, or prescription medicines face greater risks from side effects or interactions. The NIH Office of Dietary Supplements recommends maintaining a complete medicine-and-supplement record to share with clinicians.
- The supplement's exact name and dose
- When use began and whether the dose changed
- When the memory or behavior change appeared
- Whether symptoms are constant or come and go
- Any other new symptoms
Why the product label may not settle the question
Dietary supplements are not FDA-approved for safety or effectiveness before sale. The FDA also warns that contaminated products may contain hidden prescription drugs, banned substances, or harmful chemicals; absence from its database does not establish that a product is safe under its hidden-ingredient guidance. A documented example came in April 2026.
The FDA warned consumers to stop using Addall XR Shot and Addall XL and seek care for symptoms after testing identified listed and undeclared stimulant-related ingredients in the products. After urgent medical needs are addressed, report the suspected reaction to the FDA. A report can flag a possible safety problem, but it does not by itself prove the supplement caused the memory change.
