Listerine Antiseptic Mouthwash, Plaque & Gingivitis Rinse – 250ml/500ml

Details

LISTERINE® Antiseptic Mouthwash is the original, powerful oral rinse designed to kill the germs responsible for bad breath, plaque, and gingivitis. It serves as a vital adjunct to brushing and flossing, offering 100% coverage across the mouth. In Tanzania and across Africa, it provides an accessible, evidence-based method to help control the prevalence of gum disease, a common, often-untreated chronic oral health issue.

Forms/Strengths

Available as a liquid oral rinse in three main sensory formulations (Cool Mint, Original, and Fresh Burst) and two common consumer volumes: 250ml and 500ml bottles.

Main Uses (with localized benefits)

• Plaque and Gingivitis Reduction: Penetrates the plaque biofilm to reduce the germs that cause the inflammation and bleeding associated with early gum disease.
• Bad Breath Control: Kills up to 99.9% of germs that cause persistent and chronic halitosis.
• Oral Hygiene Adjunct (Tanzania/Africa Relevance): Provides a superior level of antiseptic cleaning in areas where professional dental cleanings or regular advanced care may be less accessible.

Usage Instructions (Itemized with Dosage/Duration)

1. Measure: Pour 20 mL (approximately 4 teaspoonfuls) of the rinse into a cup.
2. Rinse: Vigorously swish the liquid around the teeth and gums for a full 30 seconds.
3. Frequency: Use the rinse full strength twice daily, in the morning and at night.
4. Post-Use: Spit out the rinse; do not swallow. Do not eat or drink for 30 minutes after rinsing.

Side Effects

Common side effects are generally localized and temporary, including a strong burning or tingling sensation during use, and a temporary alteration of taste perception after rinsing.

Interactions

This product is generally compatible with common dental restorative materials (fillings, crowns) and is not known to have significant negative systemic drug interactions when used as directed (i.e., not swallowed).

Warnings/Precautions (with localized warnings)

• Age Restriction: Do not use in children under 12 years of age.
• Do Not Swallow: Accidental ingestion, especially in large amounts, is toxic due to the essential oils and alcohol content. Seek medical assistance immediately if this occurs.
• Storage (Localized Warning): Store in a cool, dry place away from direct sunlight, which may affect product integrity (especially relevant in hot African climates).

Mechanism of Action

The fixed combination of four essential oils (Menthol, Thymol, Eucalyptol, and Methyl Salicylate) is lipophilic, allowing them to rapidly penetrate the lipid layers of the plaque biofilm. This penetration disrupts the cell wall structure of the bacteria that cause gingivitis and bad breath, effectively killing the germs via an antimicrobial action.
