About Sodium Hypochlorite

Indications of Sodium Hypochlorite

Sodium Hypochlorite is a chlorine-releasing oxidizing agent used, in appropriately diluted, medical-grade preparations, for its broad-spectrum antimicrobial (antibacterial, antiviral, antifungal, and sporicidal) activity. It is not an antibiotic and is not used as a systemic antimicrobial; it is a topical/local antiseptic and disinfectant. Its labeled and clinically established uses include:

  • Established/labeled use — antiseptic wound cleansing and irrigation: Diluted, medical-grade Sodium Hypochlorite solutions (e.g., Dakin's-type solutions at approximately 0.25%, 0.125%, or 0.0125–0.005% concentrations) are used for cleansing and irrigation of acute and chronic wounds, ulcers, and surgical sites to reduce microbial bioburden.
  • Guideline-supported dental/endodontic use: In dentistry, dilute Sodium Hypochlorite solution (commonly 0.5%–6%, selected by the treating dentist) is used as the standard root canal irrigant during endodontic (root canal) therapy to dissolve organic pulp tissue and disinfect the root canal system. This use requires administration by a qualified dental professional using specialized delivery.
  • Adjunct/institutional use: Diluted Sodium Hypochlorite solutions are also used as environmental/surface and instrument disinfectants in healthcare settings; this is a disinfection use rather than a therapeutic indication in a patient.

Important: Ordinary household bleach-strength Sodium Hypochlorite (typically 3%–8%, often with added surfactants/fragrances) is not the same as a medical-grade diluted preparation and must never be applied to skin/wounds, used in the eyes, or swallowed. Only formulations specifically labeled and diluted for the intended medical or dental use should be used on or in the body.

Dosage & Administration of Sodium Hypochlorite

IndicationTypical ConcentrationAdministration
Antiseptic wound cleansing/irrigationDakin's-type Sodium Hypochlorite solution, approximately 0.25%, 0.125%, or 0.0125%–0.005% (as selected by the clinician based on wound type)Irrigate or moisten sterile gauze/dressing with the solution and apply to the wound as directed, typically once to a few times daily, or as prescribed; do not use full-strength/higher concentrations than directed.
Root canal (endodontic) irrigationSodium Hypochlorite solution, typically 0.5%–6%, per the treating dentist's protocolAdministered only by a qualified dental professional using a syringe with a specialized irrigation needle placed short of the root apex, with copious, slow, low-pressure irrigation of the canal system during instrumentation.

See Precautions and Warnings for handling, dilution, and administration cautions applicable to Sodium Hypochlorite.

Side Effects of Sodium Hypochlorite

When medical-grade Sodium Hypochlorite is used at the correct, labeled dilution and as directed, it is generally well tolerated locally. Reported adverse effects include:

  • Common/local: Transient stinging, burning, or irritation at the application/irrigation site; temporary bleaching or discoloration of skin, hair, clothing, or dressings in contact with the solution.
  • Less common: Allergic contact dermatitis or hypersensitivity reaction at the site of use.
  • With inappropriate concentration, prolonged contact, or misuse: Chemical burns, tissue irritation, or delayed wound healing from cytotoxic effects on healthy tissue; in dental use, extrusion of Sodium Hypochlorite irrigant beyond the root apex can cause significant pain, swelling, tissue necrosis, or nerve injury (an uncommon but recognized procedural complication requiring immediate dental management).

Contraindications of Sodium Hypochlorite

Sodium Hypochlorite (in its medical-grade, appropriately diluted form) is contraindicated in:

  • Patients with known hypersensitivity/allergy to Sodium Hypochlorite or to chlorine-releasing compounds.
  • Oral ingestion or any internal/systemic administration — Sodium Hypochlorite preparations for wound or dental irrigation are for topical/local professional use only, never for swallowing.
  • Ophthalmic use — Sodium Hypochlorite must not be instilled in or allowed to contact the eyes.

Use of non-medical-grade or household-strength Sodium Hypochlorite (e.g., ordinary bleach) for wound care, dental irrigation, or any use on or in the body is not appropriate under any circumstance and is not a substitute for a medical-grade labeled product.

Frequently Asked Questions about Sodium Hypochlorite

What is Sodium Hypochlorite used for?

Sodium Hypochlorite, in medical-grade diluted solutions, is used as a topical antiseptic to cleanse and irrigate wounds and, in dentistry, as the standard irrigating solution during root canal (endodontic) treatment. It works by releasing chlorine-based compounds that kill or inactivate a broad range of bacteria, viruses, and fungi.

Can I use household bleach instead of a medical Sodium Hypochlorite product on a wound?

No. Ordinary household bleach is a much higher, non-medical-grade concentration of Sodium Hypochlorite and often contains added chemicals; it must never be applied to skin, wounds, or mucous membranes, or swallowed. Only a product specifically labeled and diluted for medical wound care should be used, and only as directed by a healthcare professional.

Is Sodium Hypochlorite safe to use during pregnancy or breastfeeding?

Medical-grade Sodium Hypochlorite used topically as directed has minimal systemic absorption, but formal safety data in pregnancy/lactation are limited. It should be used only if clearly needed and only under the guidance of a healthcare professional, who can weigh the potential benefit against any theoretical risk. It should never be swallowed at any time.

What are the side effects of Sodium Hypochlorite?

Correctly diluted Sodium Hypochlorite used as directed is usually well tolerated, though it can cause transient stinging, irritation, or bleaching/discoloration of skin, hair, or clothing at the site of use. Rarely, allergic skin reactions can occur. If the concentration is too high or contact is prolonged, chemical burns or tissue irritation can result, and in dental use, extrusion beyond the root canal apex can cause pain and swelling.

Is Sodium Hypochlorite an antibiotic?

No. Sodium Hypochlorite is an antiseptic and disinfectant, not an antibiotic. It works by direct chemical oxidation of microbial components at the site of application, rather than through the targeted biological mechanisms used by systemic antibiotic drugs, and it is not used to treat systemic infections.

What should I do if Sodium Hypochlorite is accidentally swallowed or gets in the eyes?

If Sodium Hypochlorite solution is swallowed, splashed in the eyes, or grossly overexposed to (for example, inhaling fumes from mixing it with another chemical), seek immediate emergency medical attention or contact a poison control center right away. For eye contact, rinse the eyes immediately and thoroughly with clean water while seeking medical help. Do not attempt specific home treatment on your own.
