Summary
Theophylline overdose can cause severe metabolic issues like acidosis and hypokalemia, often missed by clinicians. Prompt recognition and holding theophylline are crucial for patient recovery.
Area of Science:
- Pulmonology
- Clinical Toxicology
- Internal Medicine
Background:
- Theophylline is a common medication for bronchospastic lung diseases.
- Theophylline overdose can lead to serious complications, including gastrointestinal, cardiac, metabolic, and acid-base disturbances.
- Under-recognition of theophylline's role in toxicity is a significant clinical challenge.
Observation:
- A case report details an 80-year-old male hospitalized with profound metabolic disturbances.
- Typical causes for the patient's abnormalities were ruled out.
- Elevated theophylline levels were detected, and the patient improved after discontinuation of the medication.
Findings:
- Theophylline toxicity can manifest as hypokalemia, lactic acidosis, and ketoacidosis.
- Clinicians often fail to suspect theophylline as the cause of these metabolic complications.
- The study reviews potential mechanisms for these rare metabolic disturbances.
Implications:
- A high index of suspicion for theophylline toxicity is essential in patients presenting with unexplained acidosis or hypokalemia.
- Early identification and management of theophylline toxicity can prevent severe patient outcomes.
- This highlights the importance of considering medication side effects in complex clinical presentations.
