Chlorhexidine Gluconate + Lidocaine (lignocaine) + Metronidazole is a triple-action periodontal gel containing Chlorhexidine Gluconate (an antiseptic), Lidocaine (a local anaesthetic), and Metronidazole (an antibiotic). It is used to treat painful infections of the gums and oral cavity, such as periodontitis and mouth ulcers. It works by eliminating the bacteria causing the infection while providing immediate numbing relief to the affected area.

Chlorhexidine Gluconate + Lidocaine (lignocaine) + Metronidazole is a topical periodontal formulation that combines Chlorhexidine Gluconate (Chlorhexidine Gluconate), Lidocaine (Lidocaine), and Metronidazole (Metronidazole). It is used as an adjunct in the management of inflammatory and infectious conditions of the gums, where local antimicrobial action and symptom relief are both required.

Chlorhexidine provides broad antiseptic activity by reducing bacterial load in the oral cavity. Metronidazole is effective against anaerobic bacteria commonly involved in periodontal infections, helping control infection at the local site. Lidocaine acts as a local anesthetic by blocking nerve signal transmission, providing temporary relief from pain and discomfort.

When applied topically, the formulation acts directly at the affected area, helping reduce microbial activity and improve patient comfort during oral hygiene measures. It is typically used for short-term management under dental supervision as part of a broader periodontal treatment plan, which may also include mechanical cleaning and oral hygiene practices.

The product should be used exactly as prescribed. Overuse or prolonged unsupervised application may lead to local irritation or reduced antimicrobial effectiveness.

Dentists and doctors may prescribe Chlorhexidine Gluconate + Lidocaine (lignocaine) + Metronidazole for:

Periodontal Diseases

Treatment of painful gingivitis, periodontitis, or inflammatory gum conditions.

Pericoronitis

Infection and swelling around a partially erupted tooth, common with wisdom teeth.

Mouth Ulcers

To reduce pain and prevent secondary bacterial infection in severe aphthous sores.

Post-Dental Surgery

To prevent localised infection (such as "dry socket") and manage pain following extractions or gum surgery.

Stomatitis

Inflammation of the mucous membrane of the mouth associated with bacterial overgrowth.

Chlorhexidine Gluconate + Lidocaine (lignocaine) + Metronidazole provides benefits such as:

• Triple-Action Relief: Manages infection, limits bacterial growth, and numbs pain in a single application.

• Fast-Acting Anaesthesia: Lidocaine begins to soothe localised pain within minutes of application.

• Deep Antibacterial Action: Metronidazole reaches anaerobic bacteria that are often resistant to other surface treatments.

• Sustained Antiseptic Effect: Chlorhexidine binds to oral tissues, providing a "reservoir" effect that continues to work after application.

• Improved Patient Comfort: Reduces the throbbing and sensitivity often associated with acute gum infections.

• Targeted Application: The gel format allows for precise placement on the affected area, minimising systemic exposure.

Chlorhexidine Gluconate + Lidocaine (lignocaine) + Metronidazole is generally well tolerated when used as an oral gel, but some localised effects are common.

Common Side Effects

• Temporary numbness of the tongue or cheeks

• Altered taste sensation (metallic or bitter taste)

• Mild, temporary stinging or burning right after application

• Temporary staining of the teeth or tongue (with prolonged use)

• Increased tartar (calculus) buildup on teeth

Uncommon Side Effects

• Dry mouth or oral irritation

• Localised swelling of the gums

• Nausea (usually only if a large amount of the gel is swallowed)

• Sensitivity of the teeth to hot or cold

Serious Side Effects

• Severe Allergic Reaction: Hives, swelling of the lips, face, or throat, or difficulty breathing.

• Mucosal Irritation: Severe peeling, blistering, or sloughing of the skin inside the mouth.

• Methemoglobinemia: A very rare condition (associated with lidocaine) causing blue/gray skin, headache, or fatigue.

Always follow the specific instructions provided by your dental professional.

Oral Application

• Wash your hands thoroughly before use.

• For better results, gently pat the affected area dry with a clean cotton swab or gauze before applying the gel.

• Apply a small amount of the gel (as directed) to the affected site using a clean fingertip or an applicator.

• Crucial: Do not rinse your mouth, drink, or eat for at least 30 to 60 minutes after application to allow the medicine to stay on the tissue.

• Use for the full duration of the prescription, even if the pain stops.

Chlorhexidine Gluconate + Lidocaine (lignocaine) + Metronidazole uses three distinct pathways to manage oral health:

• Chlorhexidine binds to bacterial cell walls and disrupts membrane integrity, increasing permeability and leading to leakage of cellular contents. This results in a reduction of the overall microbial load at the application site and helps control plaque-associated bacteria.

• Metronidazole is selectively active against anaerobic bacteria commonly involved in periodontal infections. Inside these organisms, it is converted into active compounds that interfere with bacterial DNA synthesis, leading to inhibition of bacterial growth and cell death.

• Lidocaine provides symptomatic relief by blocking voltage-gated sodium channels in nerve membranes. This prevents the generation and conduction of pain signals, resulting in temporary local analgesia at the site of application.

• Together, these actions help reduce infection, control bacterial activity, and relieve pain when the formulation is used as directed.

• To keep the medicine effective, avoid using toothpastes containing Sodium Lauryl Sulfate (SLS) immediately before or after application.

• Use a soft-bristled toothbrush during treatment to avoid further irritating the infected gum tissue.

• If you notice a "furry" feeling on your tongue or significant discolouration, a professional cleaning after treatment will resolve it.

Store the tube at room temperature in a cool, dry place away from direct sunlight. Ensure the cap is tightly closed after each use. Keep the medicine out of reach of children and pets.

• Alcohol (CAUTION): Avoid alcohol during treatment and for 24 hours after your last dose to prevent a "disulfiram-like" reaction (nausea/headache).

• Staining Foods (MILD): Coffee, tea, and red wine may increase the risk of temporary tooth staining while using this product.

• Warfarin (MILD): Metronidazole can slightly increase the blood-thinning effect of warfarin.

• Other Local Anaesthetics (CAUTION): Avoid using other numbing gels at the same time to prevent excessive absorption.

• Anionic Detergents (MILD): Avoid using mouthwashes with certain soaps or detergents that can deactivate Chlorhexidine.

• Blood Disorders (CAUTION): Use cautiously if you have a history of blood cell disorders (dyscrasias).

• Glaucoma (MILD): Some local anaesthetics should be used with caution, though systemic levels here are very low.

• Active Oral Fungal Infection (CAUTION): If you have oral thrush (candidiasis), this medicine may require an additional antifungal treatment.

Swallowing the entire tube could lead to systemic effects like dizziness, nausea, or a tingling sensation. If accidental ingestion occurs, contact a healthcare professional immediately.

If you miss a dose, apply it as soon as you remember. If it is almost time for your next dose, skip the missed one. Do not use extra gel to make up for a missed application.
