The adult dose of Debrox should be used as 1 to 5 drops twice daily up to 4 days in affected ear(s).

Debrox is an otic solution containing carbamide peroxide 6.5%, used primarily as an earwax (cerumen) removal aid. When applied to the ear canal, it releases oxygen, causing a foaming action that softens and loosens impacted wax. Proper administration is critical to avoid otic irritation or damage to the tympanic membrane. Treatment is generally limited to a specific duration before medical consultation is required. Rationale: A. True is incorrect because the specific dosage range and frequency provided do not match the standard FDA-approved labeling for this otic medication. While the medication is used for cerumen removal, the clinical guidelines dictate a higher drop count to ensure adequate saturation of the wax within the external auditory canal. B. False is the correct answer because the standard adult dose for Debrox is 5 to 10 drops, not 1 to 5. The frequency is twice daily for up to 4 days. Providing only 1 to 5 drops may result in sub-therapeutic coverage, failing to effectively emulsify the impacted cerumen for subsequent irrigation.
