[Visual hallucinations secondary to ciprofloxacin treatment]

Area of Science:

• Ophthalmology
• Pharmacology
• Clinical Medicine

Background:

• Ciprofloxacin, a fluoroquinolone antibiotic, is widely prescribed.
• Theophylline is a bronchodilator used for respiratory conditions.
• Adverse visual effects from drug interactions are a concern in patient care.

Observation:

• A 74-year-old woman developed visual hallucinations.
• The hallucinations began after administration of ciprofloxacin.
• The patient was also concurrently taking theophylline.

Findings:

• Cessation of ciprofloxacin led to the resolution of visual hallucinations.
• This suggests a potential link between ciprofloxacin and visual disturbances.
• The concurrent use of theophylline may have contributed to the adverse event.

Implications:

• Ophthalmologists should be aware of this uncommon adverse effect.
• Clinicians should consider potential visual disturbances when prescribing ciprofloxacin with theophylline.
• Further investigation into quinolone-theophylline interactions and visual side effects is warranted.
