Acetohydroxamic acid is used for:
Treating certain types of chronic urinary infections (urea-splitting) in combination with surgery (for patients with stones) or antibiotic medicines. It may also be used for other conditions as determined by your doctor.

- your urine is infected by bacteria that do not respond to acetohydroxamic acid

Contact your doctor or health care provider right away if any of these apply to you.
