Which substance is used to treat ear wax blockage?

  1. Ciprofloxacin + Hydrocortisone

  2. Carbamide Peroxide (Debrox)

  3. Naphazoline

  4. Cyclosporine

The correct answer is: Carbamide Peroxide (Debrox)

Carbamide Peroxide (Debrox) is the correct answer for treating ear wax blockage. Carbamide Peroxide works by breaking down the earwax, helping to soften and disperse it, making it easier to remove. It is a common over-the-counter medication used for the treatment of impacted earwax. The other options are incorrect: A. Ciprofloxacin + Hydrocortisone is used to treat bacterial ear infections but not specifically for ear wax blockage. C. Naphazoline is a decongestant used for nasal congestion, not for treating ear wax blockage. D. Cyclosporine is an immunosuppressant medication used to prevent organ rejection after transplant surgery, not for ear wax blockage.
