The authors have identified a dosage error in the original online version of this article (1).

On page 2, at the top of the right column, the sentence that had read “He was placed on acetazolamide 250 mg twice daily” should have read “He was placed on acetazolamide 500 mg twice daily.”

This has been corrected online.
