Product description

Hydrogen Peroxide Medicated mouthwash

Peroxyl is a medicated mouthwash used to relieved minor mouth and gum irritations by killing germs and/or preventing them from spreading and causing infection.

When Peroxyl comes into contact with mouth tissue, oxygen is released in a bubbling action providing mechanical cleansing to flush out mouth debris and help in the relief of oral irritations.

How to Use

Always use Peroxyl exactly as your dentist or pharmacist has told you. You should check with your dentist or pharmacist if you are not sure. You should not use Peroxyl at high doses or for a long time.

The duration of the treatment should not exceed 7 days.

Adults and children over 12 years: rinse with 10 ml (one capful, 10 ml line within cap) of Peroxyl for 1 minute, then spit out.

Use 3 times daily, after meals and at bedtime, or as directed by your dentist or pharmacist.

Children age 6-12 years: As above but under the supervision of an adult.

Do not store above 25°C, do not use Peroxyl after the expiry date which refers to the last day of that month or if you notice any signs of deterioration.

Hazards and Cautions

Possible side effects:

Like all medicines, Peroxyl® can cause side effects, although not everybody gets them, these may include: minor irritation and swelling of the mouth, injury to the gums, black stain on the tongue and a feeling that your tongue is hairy. You are more likely to experience these side effects if you use Peroxyl® for a long time or at high doses. These side effects should disappear when you stop using Peroxyl®. If you experience any untoward problems please tell your dentist or pharmacist.

Before you use Peroxyl:

Do not use Peroxyl® if you are allergic (hypersensitive) to hydrogen peroxide or any of the other ingredients of Peroxyl®. You should speak to your dentist or doctor if you have a month irritation that persists beyond 7 days of treatment or is severe, if you have irritation due to the wearing of braces and/or dentures, if you develop swelling in the mouth or develop a fever.

Keep out of the reach and sight of children

Special warnings:

Do not use in children under the age of 6 years. Do Not Swallow. Avoid contact with eyes.


Consult your doctor or dentist before use. Peroxyl contains levo-menthol, which if accidentally ingested in excessive amounts may cause fits (particularly in children or infants). If you, or anybody else using Peroxyl® experience fits, seek medical help, always take this container with you.

Really works! This mouthwash was recommended by my dentist for gum irratation I had. You aren't supposed to take it for more then 7 days in a row and when you spit it out it's bubbly. It really does a great job and sorts out any minor infections and bad breath that goes with it! 12 March 2010
Peroxal Mouth Wash Really is an excellent product - in my opinion is much better than any other mouthwash. 15 November 2011
Mouthwash After struggling to find this in the store I ordered 5 bottles on line as it sells out quickly. It was recommended by my dentist and, as well as treating and keeping gums healthy, it feels really fresh and does not stain your teeth. 29 October 2013
