Jaundice and eosinophilia associated with amitriptyline.

Area of Science:

• Pharmacology
• Hepatology
• Clinical Medicine

Background:

• Amitriptyline is a widely prescribed tricyclic antidepressant.
• Known side effects of amitriptyline include various hepatic complications.
• The association between amitriptyline and eosinophilia has not been previously reported.

Observation:

• A patient with depression developed eosinophilia and jaundice during amitriptyline treatment.
• The patient's symptoms improved significantly after amitriptyline was withdrawn.

Findings:

• The co-occurrence of eosinophilia and jaundice in a patient treated with amitriptyline is a novel observation.
• The resolution of symptoms upon drug withdrawal strongly suggests a causal relationship.

Implications:

• This case report expands the spectrum of known hepatic complications associated with amitriptyline.
• Clinicians should consider amitriptyline as a potential cause of eosinophilia and jaundice in patients presenting with these symptoms.
• Further investigation into the mechanisms of amitriptyline-induced hepatotoxicity may be warranted.
