Antibiotic-induced convulsions
1Department of Medical Toxicology, Good Samaritan Regional Medical Center, Phoenix, Arizona, USA.
Abstract:
Convulsive episodes are associated with the use of a number of antimicrobial agents. Although seizures may be a feature of the disease being treated, antibiotics should be considered possible causes of seizures, particularly if suggested by temporal relationships between seizure activity and drug administration. The astute clinician should be aware of the clinical settings in which antibiotic-induced seizures occur, be familiar with likely agents and their mechanisms of toxicity, and be prepared to institute appropriate management directed at this adverse effect of antimicrobial therapy.
Insights
Antimicrobial agents can cause convulsive episodes, or seizures. Clinicians should consider antibiotics as a potential cause of seizures, especially when seizures occur shortly after drug administration.
Area of Science:
- Pharmacology
- Neurology
- Infectious Diseases
Background:
- Convulsive episodes are a recognized adverse effect of certain antimicrobial agents.
- Differentiating drug-induced seizures from those related to the underlying disease is crucial for effective management.
Purpose of the Study:
- To highlight the association between antimicrobial use and seizures.
- To inform clinicians about antibiotic-induced seizures and their management.
Main Methods:
- Review of clinical literature and case reports on antimicrobial-induced seizures.
- Analysis of temporal relationships between antimicrobial administration and seizure occurrence.
Main Results:
- Several antimicrobial agents are implicated as causes of seizures.
- Temporal association between drug administration and seizure activity is a key indicator.
Conclusions:
- Antibiotics should be considered a potential cause of seizures, especially when seizures correlate with drug administration.
- Awareness of causative agents, mechanisms of toxicity, and appropriate management strategies is essential for clinicians.
