T46.4X
Poisoning by, adverse effect of and underdosing of angiotensin-converting-enzyme inhibitors
Clinical Classification Guidelines
Medical Intelligence & Overview
ICD-10 code T46.4X pertains to cases of poisoning, adverse effects, or underdosing of angiotensin-converting enzyme (ACE) inhibitors. These medications are primarily prescribed to treat high blood pressure and heart failure, but improper use or overdose can lead to serious health concerns. Recognizing the causes, symptoms, and management strategies can help in understanding this medical condition.
Causes & Symptoms
Clinical Causes: Accidental overdose of ACE inhibitors Intentional self-harm or overdose Misuse or incorrect dosing by healthcare providers or patients Drug interactions leading to increased levels of medication Reduced elimination due to kidney impairment Use of expired or improperly stored medication
Key Symptoms: Persistent or severe cough Dizziness, especially upon standing Low blood pressure (hypotension) Elevated potassium levels (hyperkalemia) Fatigue or weakness Nausea and vomiting Kidney dysfunction signs such as decreased urine output Swelling of the face, lips, or throat in cases of allergic reactions Altered mental status in severe cases Chest pain or irregular heartbeat
Diagnostic & Treatment
Diagnosis Path: Blood tests to measure potassium, renal function (creatinine, BUN) Electrocardiogram (ECG) to detect cardiac effects Serum drug levels if available Assessment for other causes of symptoms, such as infections or cardiac issues
Treatment Protocols: Discontinuing the ACE inhibitor medication immediately Monitoring vital signs closely Administering intravenous fluids to support blood pressure and kidney function Use of medications such as calcium gluconate to treat hyperkalemia Administering vasopressors in cases of severe hypotension Dialysis in cases of significant kidney impairment or high drug levels Supporting airway, breathing, and circulation as needed Addressing allergic reactions with antihistamines or epinephrine if necessary
