Which of the following is NOT a contraindication for Ciprodex?

The correct choice identifies a scenario that does not prevent the use of Ciprodex. Ciprodex is an antibiotic and anti-inflammatory ear drop, and it is generally contraindicated in cases where there is a significant risk of negative effects from the medication.

A recent ear surgery would typically warrant caution or contraindication when considering Ciprodex, as applying any medication into a freshly operated area could interfere with healing or introduce infection. In contrast, having a history of hypersensitivity to ciprofloxacin or having an allergic reaction to steroids are specific scenarios that would directly oppose the use of Ciprodex since the components in the medication could provoke a severe allergic reaction.

The use of Ciprodex in viral infections of the external ear is also contraindicated because the antibiotic properties of ciprofloxacin are ineffective against viral infections and might lead to inappropriate treatment.

Thus, while history of hypersensitivity and allergic reactions are clear contraindications, and the use in viral infections is deemed unsuitable, having had recent ear surgery is a more nuanced situation that would typically require either avoidance or medical facility oversight. Therefore, this makes the notion of prior surgery a scenario that would not inherently contraindicate the use of Ciprodex when evaluated in a clinical context.
