Ciprofloxacin-induced palatal tremor.

Area of Science:

• Neurology
• Pharmacology

Background:

• Antibiotic-induced movement disorders are rare but significant adverse effects.
• Ciprofloxacin is a broad-spectrum fluoroquinolone antibiotic with known neurological side effects.

Observation:

• An 84-year-old male patient developed palatal tremor during ciprofloxacin therapy.
• The tremor involved rhythmic movements of the soft palate, face, and trunk.
• Symptoms emerged during antibiotic treatment.

Findings:

• This case represents the first documented instance of palatal tremor secondary to ciprofloxacin use.
• Discontinuation of ciprofloxacin led to symptom resolution.
• Co-administration of sodium valproate was part of the treatment regimen.

Implications:

• Clinicians should consider ciprofloxacin as a potential cause of palatal tremor.
• Awareness of this adverse drug reaction is crucial for patient safety.
• Further research may elucidate the mechanisms of fluoroquinolone-induced movement disorders.
