Uses and actions:
Boric acid (boracic acid) possesses bacteriostatic and fungistatic properties. Topical powder use has been superseded by more effective and less toxic disinfectants. Boric acid Pessaries and capsules however, inserted in the vagina have been used successfully as a treatment for vaginal yeast infections.
Boric acid should never be swallowed.
Absorption & fate of systemic boric acid:
About 50% of the amount absorbed is excreted in the urine within 12 hours, with the remainder probably excreted over three to seven days. The slow excretion of boric acid can lead to cumulative toxicity during repeated use. Symptoms of acute poisoning are vomiting and diarrhoea, rash and stimulation of the C.N.S., followed by depression. Chronic intoxication may lead to anorexia, debility, confusion, dermatitis, menstrual disorders, anaemia and convulsions.
Boric acid capsules should not be used during pregnancy. Prescribers may contact Stenlake Compounding Chemist for information relating to the use of Boric Acid to treat Candida Glabrata.
