Natrio Tetraborico Vakos Xt (Borax)

Borax is used as a vaginal antiseptic to manage microbial presence in the genital tract.

• Vaginal antisepsis: reduces bacterial and fungal colonisation during routine gynecological care.
• Pre‑operative preparation: helps cleanse the vaginal area before surgical procedures.
• Adjunct to topical therapy: may be combined with other agents to enhance antimicrobial effect.

• Borax dissociates to borate ions that interfere with microbial enzyme systems and membrane integrity. The borate ion can bind to diol groups on cell‑surface proteins, disrupting metabolic pathways and inhibiting growth of bacteria and fungi. In the vaginal mucosa, this results in a reduction of microbial load without systemic absorption at typical topical concentrations.

Borax may cause local and systemic adverse reactions, most of which are related to irritation or hypersensitivity.

Common Side Effects

• Local irritation: burning or stinging sensation at the application site.
• Itching: mild pruritus of the vaginal mucosa.
• Discharge: increased vaginal secretions or mild watery discharge.
• Redness: erythema of surrounding skin.

Serious or Rare Side Effects

• Allergic reaction: hives, swelling, or anaphylaxis requiring immediate medical attention.
• Severe dermatitis: extensive skin inflammation and blistering.
• Systemic toxicity: nausea, vomiting, or renal impairment after excessive absorption.
• Chemical burns: deep tissue injury if applied to compromised mucosa.

When using Borax vaginal preparation, several precautions should be observed to minimise risk.

• Pregnancy: safety not established; avoid use unless prescribed.
• Breastfeeding: unknown safety; consider alternatives.
• Allergy: discontinue if hypersensitivity signs appear.
• Renal impairment: use with caution due to potential systemic absorption.
• Concurrent vaginal products: avoid mixing with other irritants or antiseptics.
• Store at ambient temperature: keep in original container, protect from moisture and direct sunlight.

Borax can interact with certain agents, affecting tolerability or efficacy.

Major Interactions (Avoid)

• Other vaginal antiseptics: combined use may increase irritation.
• Topical steroids: may mask early signs of adverse reaction.
• Sodium‑containing products: can alter pH and reduce effectiveness.

Moderate Interactions (Monitor Closely)

• Systemic antibiotics: monitor for additive antimicrobial effect.
• Contraceptive devices: assess for potential impact on device material.
• Skin sensitizers: increased risk of allergic response.
