Acetohydroxamic acid and Oxsoralen Topical

• Generic Name: acetohydroxamic acid
• Dosage Forms: n.a.

Acetohydroxamic acid helps prevent a build-up of ammonia in urine that can be caused by a bladder infection. Increased ammonia in urine can cause the growth of kidney stones.

Acetohydroxamic acid is used to keep urine ammonia levels low in people who have a certain type of chronic bladder infection.

Acetohydroxamic acid is not an antibiotic and will not treat the infection itself. acetohydroxamic acid is only part of a treatment program that may also include antibiotics to treat the infection, and surgery to remove kidney stones. Follow your doctor's instructions very closely.

Acetohydroxamic acid may also be used for purposes not listed in this medication guide.
