Abstract
Doxycycline is a commonly used antibiotic, but rarely, it can induce pseudotumor cerebri (PTC), a condition marked by increased intracranial pressure without a mass lesion. We report a case of a 35-year-old woman with diabetes and stage 4 chronic kidney disease who developed headache and blurry vision two weeks after completing doxycycline for H. pylori. Imaging was unremarkable, but lumbar puncture showed elevated opening pressure (40 cm H₂O) with normal CSF, confirming PTC. The patient improved with acetazolamide and was asymptomatic on follow-up. This case underscores the need for clinicians to consider doxycycline-induced PTC in patients presenting with visual changes or headaches after antibiotic therapy.
