and/or dentures, or swelling or fever develops, the patient's condition
needs to be re-evaluated by a doctor or dentist.
Overdose can injure the gums and continued use of hydrogen peroxide

‘black hairy tongue’ therefore using this product at high doses or for long
periods of time is not recommended.

Undesirable effects

Some cases of mucosal irritation and swelling of the oral tissues have been reported
specially with high doses or in continued use (see special warnings, above). The
symptoms will resolve on stopping treatment with Peroxyl.
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is
important. It allows continued monitoring of the benefit/risk balance of the medicinal
product. Healthcare professionals are asked to report any suspected adverse reactions via
Yellow Card Scheme at: www.mhra.gov.uk/yellowcard.

4.9.

Overdose
Peroxyl is a dilute hydrogen peroxide solution and is unlikely to cause the
symptoms of overdosage associated with strong solutions (30-40%).
Peroxyl contains levo-menthol which if accidentally ingested at excessive
amounts may cause convulsions, particularly in infants and children.

PHARMACOLOGICAL PROPERTIES

5.1.

Pharmacodynamic properties
Pharmacotherapeutic group: Antiinfectives and antiseptics for local oral
treatment
ATC code: A01AB02
Hydrogen peroxide is an oral antiseptic cleanser. The principal action is
brought about by contact of hydrogen peroxide with peroxidases and
catalases present in tissues and saliva, which causes the rapid release of
oxygen. This provides mechanical cleansing which flushes out mouth
debris, and helps in the treatment of oral irritations.

5.2.

Pharmacokinetic Properties
In the mouth, salivary peroxidase breaks down hydrogen peroxide to release
water and oxygen.

5.3.

Pre-clinical Safety Data
Low doses of hydrogen peroxide do not produce tissue damage or result in
neoplastic changes. Application of Peroxyl to abraded mucosa in the hamster
cheek pouch study over 21 days showed no adverse effect.

Hydrogen peroxide is not genotoxic in animals. The available data on
reproductive toxicology are incomplete but do not indicate an effect at low
concentrations.
