Who should not take Ciprofloxacin
A contraindication is a condition under which Ciprofloxacin (Ciprofloxacin) should not be taken because the risk outweighs the benefit. Ciprofloxacin has both absolute contraindications (do not use) and relative cautions (use only after careful review). This page summarises both at the 250mg, 500mg, 750mg dosing range.
Absolute contraindications
According to the prescribing information for Ciprofloxacin, absolute contraindications typically include severe allergic reactions to the active ingredient or excipients, severe hepatic or renal impairment, certain cardiovascular conditions, and concurrent use of specific interacting medications. The exact list depends on the molecule and is detailed in the official label.
Relative cautions
Relative cautions are situations where Ciprofloxacin can be used but with extra monitoring, dose reduction or alternative considered. These often include mild-to-moderate organ impairment, age extremes, multiple comorbidities, and complex medication regimens. Ciprofloxacin inhibits bacterial DNA gyrase (topoisomerase II) and topoisomerase IV, enzymes essential for DNA replication, transcription and repair.
