Common Overdose Symptoms of Tigecycline
Tigecycline, an antibiotic used for complicated infections, has no specific antidote. Overdose symptoms primarily involve nausea, vomiting, and diarrhea, reflecting its gastrointestinal side effects at high doses.[1]
What Happens in Animal Studies?
In mice and rats given tigecycline at supratherapeutic doses (up to 4 times human levels), symptoms included emesis, lethargy, and ataxia. No deaths occurred even at 100 times the human dose.[1][2]
Human Overdose Cases
Limited reports exist from clinical trials and post-marketing data. One case involved a patient receiving 200 mg (four times the standard 50 mg dose) who experienced transient nausea and vomiting without serious outcomes. Symptoms resolved with supportive care like gastric lavage and activated charcoal.[1]
Severe Overdose Risks
Excessive doses may lead to exaggerated side effects like severe nausea, abdominal pain, or pancreatitis. Hepatotoxicity or renal impairment could worsen in patients with pre-existing conditions, though direct causation is unconfirmed.[1][3]
What to Do in Case of Overdose
Discontinue tigecycline immediately. Provide supportive treatment: monitor vital signs, hydrate, and manage symptoms (e.g., antiemetics for vomiting). Hemodialysis removes little tigecycline due to high protein binding and large volume of distribution.[1][2]
