Buy Colgate Peroxyl Medicated Mouthwash

Colgate Peroxyl Medicated Mouthwash is a medicated mouthwash used to relieve minor mouth and gum germs. 

The mint flavoured mouthwash kills germs and prevents them from spreading and causing infection. 

 

How Colgate Peroxyl Medicated Mouthwash works

When the peroxyl in the mouthwash comes into contact with your mouth tissue, oxygen is released in a bubbling action. This provides mechanical cleansing, flushing the mouth debris and helping to relieve oral irritations. 

 

Directions

Always use Colgate Peroxyl Medicated Mouthwash exactly as described in the patient information leaflet or as your doctor / Chemist4U pharmacist has told you. 

Rinse your mouth with 1 capful of peroxyl for 1 minute, then spit out. 

Use 3 times daily, after meals and at bedtime. 

 

Side effects

Like all medicines, Colgate Peroxyl Medicated Mouthwash may cause side effects in some people, but these won’t affect everybody. Common side effects include: 

 

  • Minor irritation and swelling of the mouth 
  • Injury to the gums
  • Feeling that your tongue is hairy

 

If you experience any side effects, including any not included in the patient information leaflet, you can report them using the MHRA Yellow Card Scheme.

 

Serious side effects

Seek emergency medical attention if you notice any signs of a severe allergic reaction, symptoms of which include swelling of the face and throat, skin rash, breathing difficulties and/or loss of consciousness.
