T44.7
Poisoning by, adverse effect of and underdosing of beta-adrenoreceptor antagonists
Clinical Classification Guidelines
Medical Intelligence & Overview
ICD-10 code T44.7 covers incidents where individuals experience poisoning, adverse effects, or accidental underdosing related to beta-adrenoreceptor antagonists, commonly known as beta-blockers. These medications are widely used to manage heart conditions, high blood pressure, and other health issues. While effective, misuse or overdose can lead to serious health problems, making awareness of their potential effects important for both healthcare professionals and patients.
Causes & Symptoms
Clinical Causes: Intentional overdose, often due to suicide attempts or self-harm. Accidental overdose, especially in elderly patients or those taking multiple medications. Incorrect dosage administration, such as misreading prescription labels or misunderstanding instructions. Drug interactions which enhance the effects of beta-blockers, leading to toxicity. Underdosing or skipped doses that could affect treatment efficacy but are less likely to cause poisoning.
Key Symptoms: Slow heart rate (bradycardia) Low blood pressure (hypotension) Dizziness or lightheadedness, especially upon standing Fatigue or weakness Shortness of breath or bronchospasm, particularly in asthmatic patients Confusion or memory impairment in severe cases Nausea and vomiting Cold extremities or numbness Cardiac arrest in extreme overdoses
Diagnostic & Treatment
Diagnosis Path: Diagnosis involves a thorough medical history review and clinical examination. Blood tests can identify elevated levels of beta-blockers in the bloodstream, confirming poisoning. Electrocardiograms (ECGs) are useful to assess cardiac effects such as bradycardia or arrhythmias. Additional tests may include blood pressure monitoring and assessment of respiratory function to determine the severity of the effects.
Treatment Protocols: Treatment for poisoning by beta-adrenoreceptor antagonists can vary based on the severity of symptoms. Common approaches include:
