Cardiovascular evaluation after ECG changes on amphetamine (Adderall)
ECG changes that occur during treatment with an amphetamine should prompt reassessment for clinically significant cardiac adverse effects. Referral for cardiology evaluation and medication adjustment are recommended when significant cardiac abnormalities or symptoms are identified. [1]
Immediate safety actions
- The amphetamine should be discontinued while cardiac adverse effects are evaluated when ECG abnormalities or cardiac symptoms raise concern for serious underlying pathology. [1]
- Urgent clinical evaluation should be performed for red-flag symptoms such as chest pain, syncope, or shortness of breath because these symptoms require additional testing to determine whether serious cardiac adverse effects are present. [1]
- A 12-lead ECG should be repeated and interpreted in clinical context with physical examination and symptom history. [1]
Risk stratification for stimulant continuation vs discontinuation
- Cardiology consultation should be obtained when ECG findings raise concern for malignant arrhythmia or ischemia patterns. [1]
- In stimulant therapy, the emergence of conditions associated with sudden cardiac death or clinically significant uncontrolled arrhythmia should lead to consideration of discontinuation until further testing is completed. [1]
- Examples of ECG findings from the AHA/American Academy of Pediatrics framework that warrant cardiology consultation include prolonged QTc and patterns suggesting ischemia or inflammation (for example, abnormal T-wave morphology or ST-segment depression). [1]
ECG findings requiring cardiology consultation (examples)
- QTc prolongation thresholds and other abnormal repolarization patterns are included among ECG findings for which consultation is recommended. [1]
- Ventricular arrhythmias or conduction abnormalities with higher clinical concern are included among ECG findings for which consultation is recommended. [1]
Monitoring while on ADHD medications
- Blood pressure and pulse should be evaluated shortly after initiation of ADHD medication and then periodically thereafter. [1]
- Ongoing assessment should include inquiry about cardiac symptoms and new family history of sudden or unexplained death. [1]
Atomoxetine management for nausea (Strattera)
Nausea is a common side effect of atomoxetine. [3]
Atomoxetine dosing and administration for nausea
- Atomoxetine can be taken with or without food. [3]
- Prescriber adjustment of dose or trial continuation for tolerability is appropriate when adverse effects are present but serious cardiac symptoms are absent. [3]
When to escalate beyond symptom management on atomoxetine
- Atomoxetine should be assessed promptly for cardiac symptoms such as chest pain, shortness of breath, or fainting because medical attention is recommended for these symptoms while taking the medication. [3]
- If cardiac symptoms occur during atomoxetine therapy, further evaluation should proceed to determine whether serious cardiac adverse effects are present. [1]
