pharmachologic effect

Boric acid is a powerful antiseptic. It destroys various microorganisms due to the processes of coagulation and denaturation (the violation of the tertiary structure of the protein molecule) of their intracellular proteins. Boric acid is active against various bacteria, viruses, fungi and ectoparasites (lice, mites).

The drug is used for external use. After application to the mucous membrane or skin, it exerts a pharmacological effect and destroys microorganisms causative agents of infectious pathology. Boric acid can be partially absorbed into the systemic circulation.

Indications for use

The use of boric acid as an antiseptic is shown for etiotropic (destruction of the pathogen microorganism) treatment of various infectious processes of skin and mucous membranes, these include:

  • Acute otitis media (infectious inflammation of the outer and middle ear), which uses a solution of boric acid.
  • Infections of the skin - fungal skin damage caused by various fungi and purulent-inflammatory processes (furuncle, carbuncle, pyoderma, eczema ).
  • Conjunctivitis is an infectious inflammation of the conjunctiva of the eyes.
  • Pediculosis is an ectoparasitosis caused by lice.
  • In the complex treatment of scabies (parasitism in the skin of an itch mite).
  • Colpitis is an infectious pathological process of the vaginal mucosa.

The main condition for the correct use of the drug is the integrity of the skin or mucous membranes.

Contraindications for use

The use of boric acid is contraindicated for various pathological and physiological states of the organism, which include:

  • Violation of the integrity of the skin or mucous membranes (including the eardrum) in the area of ​​application of the drug.
  • Individual intolerance or hypersensitivity reaction to boric acid or ancillary components of its various dosage forms.
  • Pregnancy at any time and breastfeeding - as boric acid is absorbed into the systemic bloodstream from the surface of the skin or mucous membranes, its negative impact on the developing fetus is not ruled out.
  • Violation of the functional activity of the kidneys with the development of their deficiency.
  • Children under the age of 15 years.

Before you start using the drug, you need to make sure there are no contraindications.

Dosing and Administration

Regardless of the dosage form, Boric acid is used only externally. It is applied to the area of ​​localization of the infectious inflammatory process. There are such ways of using different medicinal forms of the drug:

  • A solution of boric acid - applied to the skin or scalp (with pediculosis) with a cotton-tampon 2-3 times a day. For treatment of acute otitis media, the solution is instilled into the external auditory meatus in the amount of 1-2 drops 2-3 times a day.
  • Ointment - is applied to the mucous membranes with a uniform thin layer, with conjunctivitis a small amount of ointment is placed under the conjunctival sac. Ointment is applied 2 times a day.
  • Powder - this dosage form is used to treat infectious processes in the skin accompanied by wetting (wet eczema), the affected area is powdered with a thin layer 2 times a day.

The duration of the course of treatment is determined by the severity of the course of the main infectious pathological process, the degree of decrease in the intensity of symptoms and the tolerability of the drug. Usually the treatment course is set individually by the attending physician.

Side effects

Most side effects and negative reactions during the application of boric acid are associated with its absorption into the systemic bloodstream, these include:

  • Dyspeptic syndrome (nausea, vomiting, unstable stool, abdominal pain)
  • From the central nervous system - headache, confusion (until its complete absence), convulsions .
  • On the part of the cardiovascular system - a decrease in systemic arterial pressure (hypotension), up to a shock state, tachycardia (rapidity of heart contractions).
  • From the urinary system - a decrease in the daily volume of urine (a decrease in diuresis).

It is also possible to develop local negative side effects in the area of ​​application of the drug in the form of reaction of irritation, desquamation (sloughing of the epithelium). Sometimes allergic reactions develop on the skin in the form of rash and itching, urticaria (a characteristic rash and swelling of the skin, reminiscent of a nettle burn). In rare cases, the most severe course of the allergic reaction is angioneurotic edema of Quincke (pronounced edema of the skin and subcutaneous tissue in the face and external genital organs) and anaphylactic shock (a progressive decrease in systemic arterial pressure with the development of multiple organ failure).

special instructions

Before applying boric acid, you should carefully read the instructions to the drug, it is important to pay attention to several features regarding its use:

  • You can not wash cavity organs (stomach, intestines) with a solution of boric acid, as this can lead to severe overdose and absorption of a large amount of boric acid into the systemic bloodstream.

Then, the oppression of the functional activity of the nervous system, the confusion of consciousness, up to its loss, a marked decrease in systemic arterial pressure, are added. With chronic poisoning (the absorption of a small amount of boric acid into the blood for a long time), anemia (anemia), stomatitis (inflammation of the oral mucosa), alopecia (hair loss), cachexia (pronounced general exhaustion), and menstrual cycle disorders. In the case of an overdose, general detoxification and symptomatic therapy are carried out.
