Care Chlorhexidine Digluconate 0.2% Antiseptic Peppermint Mouthwash - 300ml (BRAND MAY VARY)

What Is Chlorhexidine Mouthwash and How Does It Help?

If you've been dealing with sore, bleeding gums, persistent mouth ulcers, or your dentist has flagged early signs of gum disease, you're probably looking for something that actually works. Chlorhexidine mouthwash is one of the most clinically recognised antiseptic rinses available over the counter in the UK. This 300ml bottle contains chlorhexidine digluconate at a 0.2% concentration — the standard therapeutic strength used in dental practice — with a refreshing peppermint flavour to make daily use more comfortable. You can browse our full range of oral health products to find everything you need for a complete mouth care routine.

Gum disease affects a significant proportion of UK adults, and the NHS recommends antiseptic mouthwashes as part of a broader oral hygiene approach. This product is available without a prescription, making it easy to access when you need it most.

How Does Chlorhexidine Digluconate 0.2% Mouthwash Work?

Chlorhexidine digluconate is a broad-spectrum antiseptic agent. It works by binding to bacterial cell membranes and disrupting their integrity, which kills the bacteria responsible for plaque formation, gingivitis, and oral infections. What makes it particularly effective is its substantivity — it adheres to oral tissues and continues releasing antimicrobial activity for several hours after you've finished rinsing.

• Binds to negatively charged bacterial cell walls, causing membrane disruption
• Kills both gram-positive and gram-negative bacteria commonly found in the mouth
• Reduces dental plaque accumulation when used consistently
• Provides residual antimicrobial activity for up to 12 hours post-rinse

Who Should Use This Antiseptic Peppermint Mouthwash?

This mouthwash is suitable for adults and young people aged 12 and over who need targeted antiseptic support for their oral health. It's particularly useful if you've recently had dental surgery, are managing gingivitis, or have been advised by your dentist to use an antibacterial rinse. It's not a replacement for brushing and flossing — think of it as an additional layer of protection.

• Adults with gingivitis or early-stage gum disease
• Patients recovering from dental extractions or oral surgery
• People with recurrent mouth ulcers or oral infections
• Those with dentures or orthodontic appliances prone to plaque build-up

Is This Mouthwash Suitable for Sensitive Mouths and How Should It Be Stored?

If you have a known allergy to chlorhexidine or any of the excipients in this formulation, do not use this product. People with sensitive oral tissues may notice a temporary burning sensation or altered taste — this is common and usually settles with continued use. Store the bottle below 25°C, away from direct sunlight, and keep it out of reach of children. Do not use after the expiry date printed on the label.

What Do You Need to Know Before Using This Mouthwash?

Before using this product, read the following contraindications and warnings carefully. Not everyone is suitable for this mouthwash, and it's important to check before you start.

• Do not use if you are allergic to chlorhexidine digluconate or any other ingredient in the formulation
• Not suitable for children under 12 years of age
• Do not swallow — this product is for rinsing only
• Avoid contact with eyes and ears
• If you have open wounds or ulcers in the mouth, use with caution and seek dental advice first
• Inform your dentist or pharmacist if you are pregnant or breastfeeding before use

There are no significant systemic drug interactions associated with chlorhexidine mouthwash used at this concentration, as absorption through the oral mucosa is minimal. However, note the following:

• Do not use immediately after toothpaste — rinse your mouth with water first, as some toothpaste ingredients (such as sodium lauryl sulphate) may reduce the effectiveness of chlorhexidine
• Avoid using alongside other mouthwashes unless directed by a healthcare professional

How Should You Use This Antiseptic Mouthwash?

Using this mouthwash correctly makes a real difference to how well it works. Follow these steps each time you use it:

1. Measure 10ml of the mouthwash using the cap or a measuring cup
2. Rinse thoroughly around your mouth for approximately one minute
3. Spit the mouthwash out completely — do not swallow
4. Do not eat, drink, or rinse your mouth with water for at least 30 minutes afterwards
5. Use twice daily — morning and evening — after brushing your teeth

What Are the Possible Side Effects of This Mouthwash?

Like all medicines, this product can cause side effects, although not everyone will experience them. Knowing what to look out for helps you manage them early.

Common side effects:

• Brown staining of teeth, tongue, and dental restorations — particularly with prolonged use
• Altered or reduced taste sensation (dysgeusia)
• Mild burning or tingling sensation in the mouth
• Temporary increase in tartar (calculus) build-up

Less common side effects:

• Mouth irritation or soreness
• Swollen or painful salivary glands (parotid gland swelling)
• Allergic reactions — including rash, itching, or in rare cases, anaphylaxis (seek emergency help immediately if this occurs)

Tooth staining is the most frequently reported concern. It is generally reversible with professional dental cleaning and does not indicate damage to the tooth enamel itself.

Correct storage keeps the product effective and safe for the duration of use. Follow these guidelines:

• Store below 25°C in a cool, dry place
• Keep away from direct sunlight and heat sources

• Do not use after the expiry date printed on the bottle or carton
